Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Discontinued Operations On October 31, 2023, Synchronoss Technologies, Inc. entered into an Asset Purchase Agreement with Lumine Group Software Solutions (Ireland) Limited, pursuant to which the Company sold its Messaging and NetworkX businesses. This transaction represents a strategic shift designed to maximize shareholder value and allow the Company to solely focus on providing cloud-centric solutions. In connection with the sale transaction, the Company determined its Messaging and NetworkX Businesses qualified for discontinued operations accounting treatment in accordance with ASC 205-20. Accordingly, the operating results of, and costs to separate the Messaging and NetworkX businesses are reported in Net loss from discontinued operations, net of taxes in the Consolidated Statements of Operations for all periods presented. In addition, the related assets and liabilities held prior to the sale are reported as Assets and liabilities of discontinued operations on the Consolidated Balance Sheets. The notes to the financial statements have been adjusted on a retrospective basis. For additional information, see Note 4. Divestitures and Discontinued Operations of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary and entities in which the Company has a controlling interest. Investments in less than majority-owned companies in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. Investments in less than majority-owned companies in which the Company does not have the ability to exert significant influence over the operating and financial policies of the investee are accounted for using the cost method. All material intercompany transactions and accounts are eliminated in consolidation. Unless otherwise noted, tables are presented in U.S. dollars in thousands. Certain columns and rows may not add due to the use of rounded numbers. Percentages presented are calculated from the underlying numbers in thousands. Earnings per share amounts are computed independently for earnings from continuing operations, earnings from discontinued operations and net earnings. As a result, the sum of per-share amounts may not equal the total. Unless otherwise noted, all amounts and disclosures included in the Notes to Consolidated Financial Statements reflect only the Company's continuing operations except for the Consolidated Statements of Cash Flows, which are presented for the whole company. For supplemental cash flow disclosures, see Note 4. Divestitures and Discontinued Operations of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K. During the fourth quarter of 2023 there was a change in the capital structure due to a reverse stock split, which decreased the number of common shares outstanding. The Company retroactively displayed the effect of the change in the Consolidated Balance Sheets, and retroactively adjusted the computations of basic and diluted EPS for all periods presented on the Consolidated Statement of Operations. For additional information, see Note 15. Capital Structure of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K. Risks and Uncertainties There continue to be uncertainties regarding the current geopolitical tensions. The Company is closely monitoring the impact of the geopolitical environment on all aspects of its business, including how it will impact its customers, employees, suppliers, vendors, business partners and distribution channels. While the geopolitical environment did not materially affect the Company’s financial results and business operations for the year ended December 31, 2023, the Company is unable to predict the impact these factors will have on its financial position and operating results due to numerous uncertainties. The Company will continue to assess the evolving impact of geopolitical tensions and will make adjustments to its operations as necessary. Recently Issued Accounting Standards Standards issued not yet adopted Standard Description Effect on the financial statements Update 2023-09 - Income Taxes (Topic 740) - Improvements to Income Tax Disclosures The amendments in this Update related to the rate reconciliation and income taxes paid disclosures improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. The Company continues to evaluate these changes and does not anticipate any material impact on the Company’s consolidated financial position or results of operations upon adoption. Planned date of adoption: January 1, 2025 Update 2023-07 - Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures The amendments in this Update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this Update Requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this Update and all existing segment disclosures in Topic 280. The Company continues to evaluate these changes and does not anticipate any material impact on the Company’s consolidated financial position or results of operations upon adoption. Planned date of adoption: January 1, 2024 Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Revenue Recognition Revenues are recognized when control of the promised goods or services are transferred to the Company’s customers, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company generates all of its revenue from contracts with customers. Subscription and Transaction revenues consist of revenues derived from the processing of transactions through the Company’s service platforms, providing enterprise portal management services on a subscription basis and maintenance agreements on software licenses. The Company generates revenue from Subscription services from monthly active user fees, software as a service (“SaaS”) fees, hosting and storage fees, and fees for the related maintenance support for those services. In most cases, the subscription or transaction arrangement is a single performance obligation comprised of a series of distinct services that are substantially the same and that have the same pattern of transfer (i.e., distinct days of service). The Company applies the variable consideration allocation exception when the terms of variable payment relate specifically to efforts to satisfy the performance obligation or the transfer of service based on usage within the corresponding period, under Topic 606 Section 10-25-14(b) – in such situations the revenue booked and the revenue billed for any month are the same. When the Company does not allocate variable consideration to distinct periods of service or apply the variable consideration allocation exception, the total estimated transaction price is recognized ratably over the term of the contract, where the level of service provided to the customer does not vary significantly from one period to another. Transaction service arrangements include services such as processing equipment orders, new account setup and activation, number port requests, credit checks and inventory management. Transaction revenues are principally based on a contractual price per transaction and are recognized based on the number of transactions processed during each reporting period. Revenues are recorded based on the total number of transactions processed at the applicable price established in the relevant contract. Many of the Company’s contracts guarantee minimum volume transactions from the customer. In these instances, if the customer’s total estimated transaction volume for the period is expected to be less than the contractual amount, the Company records revenues at the minimum guaranteed amount ratably over the period covered by the minimum. Setup fees for transactional service arrangements are deferred until set up activities are completed and recognized on a straight‑line basis over remaining expected customer relationship period. Revenues are presented net of discounts, which are volume level driven. In accordance with Topic 606 Section 10-50-20, any credits due to customers, which are generally performance driven and based upon system availability or response times to incidents, are determined and accounted for as a reduction to revenue in the period in which the services are provided. The Company recognizes revenues from support and maintenance performance obligations over the service delivery period. The Company’s software licenses typically provide for a perpetual or term right to use the Company’s software. The Company has concluded that in most cases its software license is distinct as the customer can benefit from the software on its own. Software revenue is typically recognized when the software is delivered to the customer. Contracts that include software customization or specified upgrades may result in the combination of the customization services with the software license as one performance obligation. The Company does not have a history of returns, or refunds of is software licenses, however, in limited instances, the Company may constrain consideration to high-risk customers, until collection is resolved. The Company’s professional services include software development and customization. The contracts generally include project deliverables specified by each customer. The performance obligations in the agreements are generally combined into one deliverable and generally result in the transfer of control over time. The underlying deliverable is owned and controlled by the customer and does not create an asset with an alternative use to us. The Company recognizes revenue on fixed fee contracts on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation, or ratably to the extent the level of effort to satisfy the performance obligation is materially consistent each period. Most of the Company’s contracts with customers contain multiple performance obligations which generally include either 1) a perpetual software license with support and maintenance and sometimes a hosting agreement or 2) a term SaaS agreement, frequently sold along with professional services. For these contracts, the Company accounts for individual goods and services separately if they are distinct performance obligations. This often requires significant judgment based upon knowledge of the products, the solution provided and the structure of the sales contract. In SaaS agreements, the Company provides a service to the customer which combines the software functionality, maintenance and hosting into a single performance obligation when the customer doesn’t have the ability to take possession of the underlying software license. The Company may also sell the same three goods and services in a contract, but there may be three performance obligations, where the customer has the right to take possession of the software license without significant penalty. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. The Company estimates standalone selling prices of software based on observable inputs of past transactions to similarly situated customers. When such observable data is not available for certain software licenses because there is a limited number of transactions or prices are highly variable, the Company will estimate the standalone selling price using the residual approach. Standalone selling prices of services are typically determined based on observable transactions when these services are sold on a standalone basis to similarly situated customers or estimated using a cost-plus margin approach. Estimating the transaction price of variable consideration including the variable quantity subscription or transaction contracts in a multiple performance obligation arrangement requires significant judgment. The Company generally estimates this variable consideration at the most likely amount to which the Company expects to be entitled and in certain cases based on the expected value. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company reviews and updates these estimates on a quarterly basis. The Company’s typical performance obligations include the following: Performance Obligation When Performance Obligation is Typically Satisfied How Standalone Selling Price is Typically Estimated Software License Software License Upon shipment or made available for download (point in time) Observable transactions or residual approach when prices are highly variable or uncertain Software License with significant customization Over the performance of the customization and installation of the software (over time) Residual approach Hosting Services As hosting services are provided (over time) Estimated using a cost-plus margin approach Professional Services Consulting As work is performed (over time) Observable transactions Customization SaaS: Over the remaining term of the SaaS agreement License: Over the performance of the customization and installation of the software (over time) Observable transactions Transaction Services As transaction is processed (over time) Observable transactions Subscription Services Customer Support Ratably over the course of the support contract (over time) Observable transactions SaaS Over the course of the SaaS service once the system is available for use (over time) Estimated using a cost-plus margin approach The payments for the Company’s performance obligations are typically due within 90 days of services being provided for Software License, Professional Services, and Subscription Services, and due within 90 days of transaction for Transaction Services. Deferred Revenue Deferred revenues represent billings to customers for services in advance of the performance of services, with revenues recognized as the services are rendered. Service Level Standards Pursuant to certain contracts, the Company is subject to service level standards and to corresponding penalties for failure to meet those standards. All performance-related penalties are reflected as a corresponding reduction of the Company’s revenues. These penalties, if applicable, are recorded in the month incurred and were insignificant for the years ended December 31, 2023, 2022 and 2021, respectively. Cost of Revenues Cost of services includes all direct materials, direct labor and those indirect costs related to revenues such as indirect labor, materials and supplies and facilities cost, exclusive of depreciation and amortization expense. Research and Development Software development costs are accounted for in accordance with either ASC 985-20, “Software - Costs of Software to be Sold, Leased or Marketed,” or ASC 350-40, “Internal-Use Software.” Costs associated with the planning and designing phase of software development are classified as research and development costs and are expensed as incurred. The amounts capitalized include external direct costs of services used in developing internal-use software, and employee compensation and related expenses of personnel directly associated with the development activities. Once technological feasibility has been determined, a portion of the costs incurred in development, including coding, testing and quality assurance, are capitalized until available for general release to clients. Amortization is calculated on a solution-by-solution basis and is recognized over the estimated economic life of the software, typically ranging two The unamortized software development costs and amortization expense were as follows: Year ended December 31, 2023 2022 2021 Unamortized software development costs $ 19,327 $ 18,374 $ 17,040 Software development amortization expense $ 13,633 $ 10,265 $ 7,630 The Company recognized no impairment charges to its capitalized software intangible assets for the years ended December 31, 2023, 2022 and 2021, respectively. Concentration of Credit Risk The Company’s financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents at several major financial institutions. The Company believes that concentration of credit risk with respect to accounts receivable is limited because of the creditworthiness of its major customers. The Company’s top five customers accounted for 96.6%, 94.6% and 92.4% of net revenues for the years ended December 31, 2023, 2022 and 2021, respectively. Contracts with these customers typically run for three Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of acquisition to be cash equivalents. Accounts Receivable Accounts receivable include amounts billed to customers, claims, and unbilled revenue, which consists of amounts recognized as sales but not yet billed. Substantially all amounts of unbilled receivables are expected to be billed and collected in the subsequent year. The Company had unbilled receivable balances of $0.7 million and $0.5 million as of December 31, 2023 and 2022, respectively. Allowance for Credit Losses The Company is exposed to credit losses primarily through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Customers are pooled based on sharing specific risk factors, including geographic location. Due to the short-term nature of such receivables, the estimated accounts receivable that may not be collected is based on aging of the accounts receivable balances. Customers are assessed for credit worthiness upfront through a credit review, which includes assessment based on our analysis of their financial statements when a credit rating is not available. The Company evaluates contract terms and conditions, country and political risk, and may require prepayment to mitigate risk of loss. Specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company monitors changes to the receivables balance on a timely basis, and balances are written off as they are determined to be uncollectible after all collection efforts have been exhausted. Estimates of potential credit losses are used to determine the allowance; they are based on assessment of anticipated payment and all other historical, current and future information that is reasonably available. Fair Value of Financial Instruments and Liabilities The Company includes disclosures of fair value information about financial instruments and liabilities, whether or not recognized on the Consolidated Balance Sheets, for which it is practicable to estimate that value. Due to their short-term nature, the carrying amounts reported in the financial statements approximate the fair value for cash and cash equivalents, marketable securities, accounts receivable and accounts payable. Property and Equipment Property and equipment and leasehold improvements are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 5 years, or the lesser of the related initial term of the lease or useful life for leasehold improvements. Amortization of property and equipment recorded under a capital lease is included with depreciation expense. Expenditures for routine maintenance and repairs are charged against operations, while major replacements, improvements and additions are capitalized. Noncontrolling Interests and Mandatorily Redeemable Financial Instruments Noncontrolling interests (“NCI”) are evaluated by the Company and are shown as either a liability, temporary equity (shown between liabilities and equity) or as permanent equity depending on the nature of the redeemable features at amounts based on formulas specific to each entity. Generally, mandatorily redeemable NCIs are classified as liabilities and non-mandatorily redeemable NCIs are classified outside of stockholders’ equity in the Consolidated Balance Sheets as temporary equity under the caption Redeemable noncontrolling interests, and are measured at their redemption values at the end of each period. If the redemption value is greater than the carrying value, an adjustment is recorded in retained earnings to record the NCI at its redemption value. Redeemable NCIs that are mandatorily redeemable are classified as a liability in the Consolidated Balance Sheets under either other current liabilities or other long-term liabilities, depending on the remaining duration until settlement, and are measured at the amount of cash that would be paid if settlement occurred at the balance sheet date with any change from the prior period recognized as interest expense. If the noncontrolling interest is not currently redeemable yet probable of becoming redeemable, the Company is required to either (1) accrete changes in the redemption value over the period from the date of issuance to the earliest redemption date of the instrument using an appropriate methodology, usually the interest method, or (2) recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. The Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the noncontrolling interest to the greater of the estimated redemption value, which approximates fair value, at the end of each reporting period or the initial carrying amount. Net income attributable to NCIs reflects the portion of the net income (loss) of consolidated entities applicable to the NCI stockholders in the accompanying Consolidated Statements of Operations. The net income attributable to NCI is classified in the Consolidated Statements of Operations as part of consolidated net income and deducted from total consolidated net income to arrive at the net income attributable to the Company. Investments in Affiliates and Other Entities In the normal course of business, Synchronoss enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by Synchronoss in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. Synchronoss determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if Synchronoss is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When Synchronoss is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest. The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over and holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for using the cost method unless the investment had a readily determinable fair value, at which it would then be reported. If an entity fails to meet the characteristics of a VIE, the Company then evaluates such entity under the voting model. Under the voting model, the Company consolidates the entity if they determine that they, directly or indirectly, have greater than 50% of the voting shares, and determine that other equity holders do not have substantive participating rights. Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including other definite-lived intangible assets. Goodwill is reviewed for impairment annually in the fourth quarter or when an interim triggering event has occurred indicating potential impairment. The Company has concluded that it has one operating segment and one reporting unit. The Company tests for goodwill impairment on its reporting unit. During the Company’s qualitative assessment, the Company makes significant estimates, assumptions, and judgments, around the financial performance of the Company, changes in share price, and forecasts of earnings, working capital requirements, and cash flows. The Company considers each reporting unit's historical results and operating trends as well as any strategic difference from the Company’s historical results when determining these assumptions. The Company can opt to perform a qualitative assessment to test a reporting unit’s goodwill for impairment or the Company can directly perform the quantitative impairment test. If the Company determines that the fair value of a reporting unit is more likely than not to be less than its carrying amount, a quantitative impairment test is performed. Fair value estimates used in the quantitative impairment test are calculated using a combination of the income and market approaches. The income approach is based on the present value of future cash flows of each reporting unit, while the market approach is based on certain multiples of selected guideline public companies or selected guideline transactions. The approaches incorporate a number of market participant assumptions including future growth rates, discount rates, income tax rates and market activity in assessing fair value and are reporting unit specific. If the carrying amount exceeds the reporting unit's fair value, the Company recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The fair value measurement associated with the quantitative goodwill impairment test is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. Significant changes in the underlying assumptions used to value goodwill could significantly increase or decrease the fair value estimates used for impairment assessments. In order to assess the reasonableness of the estimated fair value of the Company’s reporting unit, the Company compares the aggregate reporting unit fair value to the Company’s market capitalization on an overall basis and calculates an implied control premium (the excess of the sum of the reporting units’ fair value over the Company’s market capitalization on an overall basis). The Company evaluates the control premium by comparing it to observable control premiums from recent comparable transactions. If the implied control premium is determined to not be reasonable in light of these recent transactions, the Company re-evaluates its reporting unit fair values, which may result in an adjustment to the discount rate and/or other assumptions. This re-evaluation could result in a change to the estimated fair value of the reporting unit. If the fair value of a reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not impaired. If the fair value of the reporting unit is less than its carrying amount, goodwill is impaired and the excess of the reporting unit’s carrying value over the fair value is recognized as an impairment loss. Impairment of Long-Lived Assets A review of long-lived assets for impairment is performed when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If an indication of impairment is present, the Company compares the estimated undiscounted future cash flows to be generated by the asset to the asset’s carrying amount. If the undiscounted future cash flows are less than the carrying amount of the asset, the Company records an impairment loss equal to the amount by which the asset’s carrying amount exceeds its fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. This fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. Significant changes in the underlying assumptions used to value long lived assets could significantly increase or decrease the fair value estimates used for impairment assessments. Long lived assets that do not have indefinite lives are amortized/depreciated over their useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reevaluates the useful life determinations each year to determine whether events and circumstances warrant a revision to the remaining useful lives. Leases Whenever the Company enters into a new arrangement, it must determine, at the inception date, whether the arrangement contains a lease. This determination generally depends on whether the arrangement conveys to the Company the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset. If a lease exists, the Company must then determine the separate lease and non-lease components of the arrangement. Each right to use an underlying asset conveyed by a lease arrangement should generally be considered a separate lease component if it both: (i) can benefit the Company without depending on other resources not readily available to the Company and (ii) does not significantly affect and is not significantly affected by other rights of use conveyed by the lease. Aspects of a lease arrangement that transfer other goods or services to the Company but do not meet the definition of lease components are considered non-lease components. The consideration owed by the Company pursuant to a lease arrangement is generally allocated to each lease and non-lease component for accounting purposes. However, the Company has elected to not separate lease and non-lease components. Each lease component is accounted for separately from other lease components, but together with the associated non-lease components. For each lease, the Company must then determine: • The lease term - The lease term is the period of the lease not cancellable by the Company, together with periods covered by: (i) renewal options the Company is reasonably certain to ex

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of revenue The Company disaggregates revenue from contracts with customers into the nature of the products and services and geographical regions. The Company’s geographic regions are the Americas, Europe, the Middle East and Africa (“EMEA”), and Asia Pacific (“APAC”). The majority of the Company’s revenue is from the TMT sector.

Trade Accounts Receivable and Contract balances The Company classifies its right to consideration in exchange for deliverables as either a receivable or a contract asset. A receivable is a right to consideration that is unconditional (i.e. only the passage of time is required before payment is due). For example, the Company recognizes a receivable for revenues related to its time and materials and transaction or volume-based contracts. The Company presents such receivables in Trade accounts receivable, net in its consolidated statements of financial position at their net estimated realizable value. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables and other applicable factors. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. For example, the Company would record a contract asset if it records revenue on a professional services engagement but are not entitled to bill until the Company achieves specified milestones. Contract asset balance at December 31, 2023 and 2022 was $1.2 million and $13.3 million, respectively. Amounts collected in advance of services being provided are accounted for as contract liabilities, which are presented as deferred revenue on the accompanying balance sheet and are realized with the associated revenue recognized under the contract. Nearly all of the Company's contract liabilities balance is related to services revenue, primarily subscription services contracts. The Company’s contract assets and liabilities are reported in a net position on a customer basis at the end of each reporting period. Significant changes in the contract liabilities balance (current and noncurrent) during the period are as follows: Contract Liabilities 1 Balance - January 1, 2023 $ 1,948 Revenue recognized in the period (164,378) Amounts billed but not initially recognized as revenue 163,525 Balance - December 31, 2023 $ 1,095 _____________________________ 1 Comprised of Deferred Revenue. $1.9 million of revenue recognized in the period was included in the contract liability balance at the beginning of the period. Revenues recognized during the year ended December 31, 2023 for performance obligations satisfied or partially satisfied in previous periods were immaterial. Contract acquisition costs In connection with the adoption of Topic 606 and the related cost accounting guidance under Accounting Standards Codification (“ASC”) 340, the Company is required to capitalize certain contract acquisition costs consisting primarily of commissions and bonuses paid when contracts are signed. For contracts that have a duration of less than one year, the Company follows a Topic 606 practical expedient and expenses these costs over the estimated customer life, because it does not pay commissions upon renewals that are commensurate with the initial contract. During the years ended December 31, 2023, 2022 and 2021 the amounts of amortization were not material and there were no impairments in relation to costs capitalized. Contract Fulfillment Costs Under ASC 340-40, the Company evaluates whether or not it should capitalize the costs of fulfilling a contract. Such costs would be capitalized when they are not within the scope of other standards and: (1) are directly related to a contract; (2) generate or enhance resources that will be used to satisfy performance obligations; and (3) are expected to be recovered. As of December 31, 2023 and 2022, the Company had $0.2 million and nil of capitalized contract fulfillment costs, respectively. Transaction price allocated to the remaining performance obligations Topic 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of December 31, 2023. The Company has elected not to disclose transaction price allocated to remaining performance obligations for: 1. Contracts with an original duration of one year or less, including contracts that can be terminated for convenience without a substantive penalty; 2. Contracts for which the Company recognizes revenues based on the right to invoice for services performed; 3. Variable consideration allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation in accordance with Topic 606 Section 10-25-14(b), for which the criteria in Topic 606 Section 10-32-40 have been met. This applies to a limited number of situations where the Company is dependent upon data from a third party or where fees are highly variable. Many of the Company’s performance obligations meet one or more of these exemptions. Specifically, the Company has excluded the following from the Company’s remaining performance obligations, all of which will be resolved in the period in which amounts are known: • consideration for future transactions, above any contractual minimums; • consideration for success-based transactions contingent on third-party data; • credits for failure to meet future service level requirements. As of December 31, 2023, the aggregate amount of transaction price allocated to remaining performance obligations, other than those meeting the exclusion criteria above, was $231.9 million, of which approximately 57.3% is expected to be recognized as revenues within 2 years, and the remainder thereafter. Estimates of revenue expected to be recognized in future periods also exclude unexercised customer options to purchase services that do not represent material rights to the customer. Customer options that do not represent a material right are only accounted for in accordance with Topic 606 when the customer exercises its option to purchase additional goods or services.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures and Discontinued Operations	Divestitures and Discontinued Operations Discontinued Operations Messaging and NetworkX Businesses Sale On October 31, 2023 (the “Closing Date”), Synchronoss Technologies, Inc. and certain of its affiliated entities (such entities, together with the Company, the “Company Group”) entered into an Asset Purchase Agreement (the “Agreement”) with Lumine Group Software Solutions (Ireland) Limited, a private limited company incorporated under the laws of Ireland, Lumine Group UK Holdco Ltd, Incognito Software Systems Inc., Lumine Group US Holdco, Inc., Lumine Group Australia Holdco Pty Ltd, Openwave Messaging (Ireland) Limited, Razersight Software Solutions Ireland Limited, Spatial Software Solutions Ireland Limited, Razorsight Software Solutions US Inc., and Openwave Messaging US Inc. (such entities, the “Buyer”), pursuant to which the Company Group sold its Messaging and NetworkX businesses (the “Messaging and NetworkX Businesses”) to Buyer (the “Transaction”) for a total purchase price of up to $41,800,000 (the “Purchase Price”), and Buyer assumed certain liabilities of the Messaging and Digital Businesses. Lumine Group Inc., the parent entity of Lumine Group Software Solutions (Ireland) Limited, guaranteed certain obligations of Buyer under the Agreement pursuant to a separate Limited Guaranty, by and between Lumine Group Inc. and the Company, dated as of the date of the Agreement. The Purchase Price, which is subject to set-off rights in certain circumstances and certain adjustments, is payable as follows: (i) $31,300,000 (as adjusted) was paid in cash to the Company on the Closing Date, (ii) an additional $7,200,000 was deposited by Buyer into an escrow account on the Closing Date (which amount will remain in escrow until reconciliation of a net tangible asset adjustment), with any amounts in such escrow account to be released from escrow to either Buyer or the Company, based on whether such reconciliation indicates a deficit or a surplus in net tangible assets relative to a negotiated target amount, following such reconciliation process, which could take in excess of 150 days following the Closing Date for the initial portion of the net tangible asset reconciliation and 300 days or more following the Closing Date for reconciliation of certain specified assets to be completed, (iii) an additional $300,000 in cash (which amount was not deposited into an escrow account) may become payable to the Company in accordance with the terms of the Agreement in the event that the voluntary disclosure process with respect to certain sales tax matters related to the Messaging and NetworkX Businesses are resolved by the Company within 9 months following the Closing Date, and (iv) an additional amount of up to $3,000,000 in cash (which amount was not deposited into an escrow account) may become payable to the Company as an earn-out based on the achievement of specified gross revenue targets for the Messaging and NetworkX Businesses in fiscal year 2023. Pursuant to the Certificate of Designations of the Series B Perpetual Non-Convertible Preferred Stock, on November 3, 2023 the Company redeemed 9,874 shares of its outstanding Series B Preferred Stock by using $10,000,000 of the Purchase Price, of which $9.9 million was related to principal and $0.1 million was related to accrued dividend. This transaction represents a strategic shift designed to maximize shareholder value and allow the Company to solely focus on providing cloud-centric solutions. In connection with the sale transaction, the Company determined its Messaging and NetworkX Businesses qualified for discontinued operations accounting treatment in accordance with ASC 205-20. The Company allocated $28.6 million goodwill to the transaction using level 3 estimates, and recognized a loss on divestiture of $16.4 million reported in Loss on divestiture in the Consolidated Statements of Operations.

(“iQmetrix ”), entered into an Asset Purchase Agreement, pursuant to which Synchronoss has agreed to sell its Digital Experience Platform and activation solutions (the “DXP Business”) to iQmetrix for up to a total purchase price of $14 million. The purchase price is payable as follows: (i) $7.5 million on the closing date of the Transaction, (ii) $0.5 million deposited into an escrow account on the Closing Date, (iii) $1 million paid twelve (12) months from the Closing Date, and (iv) $5 million that may be payable as an earn-out. This transaction closed on May 11, 2022. The Company received the $7.5 million cash payment on the transaction close date. The Company received the $0.5 million payment in escrow during the third quarter of 2022 in accordance with the terms of the Asset Purchase Agreement. The remaining $1 million escrow payment has not been received by the Company in accordance with the agreement.

For the goodwill allocation, the fair value of the Core reporting unit was estimated using a combination of the income approach, which incorporates the use of the discounted cash flow method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. Based on the fair value of the Core reporting unit and the aggregate consideration received in the transaction, the Company determined the attributable fair value of goodwill to the DXP Business was $7.6 million. The transaction resulted in a $2.5 million gain for the year ended December 31, 2022.

The A/R Facility transaction includes (i) Receivables Purchase Agreements (the “Receivables Purchase Agreements”) dated as of the Closing Date, among the Company, as initial servicer, SN Technologies, LLC, a wholly owned special purpose subsidiary of the Company (“SN Technologies”), as seller, Norddeutsche Landesbank Girozentrale, as administrative agent (the “Administrative Agent”), and the purchasers party thereto, the group agents party thereto and the originators party thereto; (ii) Purchase and Sale Agreements (the “Purchase and Sale Agreements”) dated as of the Closing Date, between the Company Group, as originators (the “Originators”), and SN Technologies, as purchaser; (iii) the Administration Agreement (the “Administration Agreement”) dated as of the Closing Date, between the Company, as servicer, and Finacity Corporation, as administrator; and (iv) the Performance Guaranty (the “Performance Guaranty”) dated as of the Closing Date made by the Company in favor of the Administrative Agent. Pursuant to the Purchase and Sale Agreements, the Originators will sell existing and future accounts receivable (and related assets) (the “Receivables”) to SN Technologies in exchange for cash and/or subordinated notes.

The Company’s commitment fee shall equal 0.85% per annum on the average daily unused outstanding capital. Pursuant to the Performance Guaranty, the Company guarantees the performance of the Originators of their obligations under the Purchase and Sale Agreements. The Company has not agreed to guarantee any obligations of SN Technologies or the collection of any of the receivables and will not be responsible for any obligations to the extent the failure to perform such obligations by the Company or any Originators results from receivables being uncollectible on account of the insolvency, bankruptcy or lack of creditworthiness or other financial inability to pay of the related obligor. Unless earlier terminated or subsequently extended pursuant to the terms of the Receivables Purchase Agreement, the A/R Facility will expire on June 23, 2025.

The Company drew $12.0 million on the A/R Facility in 2023, and had repaid the balance in 2023. The interest associated with the draw and repayment was not material for the period. The draw down and subsequent repayment of the A/R Facility represent financing activity, as reported in the Statement of Cash Flows.

Fair Value Measurements	Fair Value Measurements In accordance with accounting principles generally accepted in the United States, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy prioritizes the inputs used to measure fair value as follows: • Level 1 - Observable inputs - quoted prices in active markets for identical assets and liabilities; • Level 2 - Observable inputs other than the quoted prices in active markets for identical assets and liabilities includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and • Level 3 - Unobservable inputs - includes amounts derived from valuation models where one or more significant inputs are unobservable and require the Company to develop relevant assumptions.

The offering was conducted pursuant to an underwriting agreement (the “Notes Underwriting Agreement”) dated June 25, 2021, by and among the Company and B. Riley Securities, Inc., as representative of the several underwriters (the “Notes Underwriters”). At the closing, the Company issued $125.0 million aggregate principal amount of Senior Notes, inclusive of $5.0 million aggregate principal amount of Senior Notes issued pursuant to the full exercise of the Notes Underwriters’ option to purchase additional Senior Notes. The Notes Underwriting Agreement contains customary representations, warranties and covenants of the Company, customary conditions to closing, indemnification obligations of the Company and the Notes Underwriters, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. On June 30, 2021, the Company entered into an indenture (the “Base Indenture”) and a supplemental indenture (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) with The Bank of New York Mellon Trust Company National Association, as trustee (the “Trustee”), between the Company and the Trustee. The Indenture establishes the form and provides for the issuance of the Senior Notes. The Senior Notes are senior unsecured obligations of the Company and rank equally in right of payment with all of the Company’s existing and future senior unsecured and unsubordinated indebtedness. The Senior Notes are effectively subordinated in right of payment to all of the Company’s existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to all existing and future indebtedness of the Company’s subsidiaries, including trade payables. The Senior Notes bear interest at the rate of 8.375% per annum. Interest on the Senior Notes is payable quarterly in arrears on January 31, April 30, July 31 and October 31 of each year, commencing on July 31, 2021. The Senior Notes will mature on June 30, 2026, unless redeemed prior to maturity. The Company may, at its option, at any time and from time to time, redeem the Senior Notes for cash in whole or in part (i) on or after June 30, 2022 and prior to June 30, 2023, at a price equal to $25.75 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or after June 30, 2023 and prior to June 30, 2024, at a price equal to $25.50 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, (iii) on or after June 30, 2024 and prior to June 30, 2025, at a price equal to $25.25 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, and (iv) on or after June 30, 2025 and prior to maturity, at a price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption. On and after any redemption date, interest will cease to accrue on the redeemed Senior Notes. The Indenture contains customary events of default and cure provisions. If an uncured default occurs and is continuing, the Trustee or the holders of at least 25% of the principal amount of the Senior Notes may declare the entire amount of the Senior Notes, together with accrued and unpaid interest, if any, to be immediately due and payable. In the case of an event of default involving the Company’s bankruptcy, insolvency or reorganization, the principal of, and accrued and unpaid interest on, the principal amount of the Senior Notes, together with accrued and unpaid interest, if any, will automatically, and without any declaration or other action on the part of the Trustee or the holders of the Senior Notes, become due and payable.

(the “Agent”), a related party, pursuant to which the Company may offer and sell, from time to time, up to $18.0 million of the Company’s 8.375% Senior Notes due 2026.

Stockholders' Equity Note [Abstract]
Capital Structure	Capital Structure Reverse Stock Split On December 4, 2023, the Company’s stockholders approved proposals at a special meeting of stockholders (the “Special Meeting”) amending the Company’s Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), to effect a reverse stock split of the Company’s common stock, $0.0001 par value (“Common Stock”), at a ratio in the range of 1-for-5 to 1-to-20, and an associated reduction in the number of shares of Common Stock the Company is authorized to issue. On December 4, 2023, the Company’s Board of Directors (the “Board”) approved a final split ratio of 1-for-9 (the “Reverse Stock Split”) where each nine (9) shares of Common Stock issued and outstanding immediately prior to the Effective Time shall, automatically and without any action on the part of the respective holders thereof, be combined and converted into one (1) share of Common Stock. Following such approvals, the Company filed an amendment to the Certificate of Incorporation (the “Certificate of Amendment”) to effect the Reverse Stock Split with the Secretary of State of the State of Delaware on December 8, 2023 as of 4:01 p.m. Eastern Time. The Certificate of Amendment states that the Company is authorized to issue two classes of stock to be designated common stock (“Common Stock”) and preferred stock (“Preferred Stock”). The number of shares of Common Stock authorized to be issued is sixteen million six hundred sixty-six thousand six hundred sixty-seven (16,666,667), par value $0.0001 per share, and the number of shares of Preferred Stock authorized to be issued is ten million (10,000,000), par value $0.0001 per share. As of the opening of trading on December 11, 2023, the Company’s Common Stock began trading on a post-split basis under CUSIP number 87157B400. The Company’s Common Stock will continue to trade on the Nasdaq Capital Market under the symbol “SNCR.” The Reverse Stock Split was effected simultaneously for all shares of Common Stock issued and outstanding, and affected all holders of the Company’s Common Stock uniformly and does not affect any stockholder’s percentage ownership interests in the Company, except with respect to the treatment of fractional shares. The Company did not issue fractional shares for post-Reverse Stock Split shares in connection with the Reverse Stock Split. Stockholders who otherwise were entitled to receive a fractional share of Common Stock had such fractional share rounded up to the nearest whole share. The Company retroactively displayed the effect of the Reverse Stock Split change in the Consolidated Balance Sheets, and retroactively adjusted the computations of basic and diluted EPS for all periods presented on the Consolidated Statement of Operations. As of December 31, 2023, the Company’s authorized capital stock was 26,666,667 shares of stock with a par value of $0.0001, of which 16,666,667 shares were designated as common stock and 10,000,000 shares were designated as preferred stock, 150,000 of which were designated Series B Perpetual Non-Convertible Preferred Stock. Common Stock Each holder of common stock is entitled to vote on all matters and is entitled to one vote for each share held. Dividends on common stock will be paid when, and if, declared by the Company’s Board of Directors. No common stock dividends have ever been declared or paid by the Company. Common Stock Offering On June 29, 2021, the Company closed its underwritten public offering of common stock, par value $0.0001 per share. The offering was conducted pursuant to an underwriting agreement (the “Underwriting Agreement”) dated June 24, 2021, by and between the Company and B. Riley Securities, Inc., as representative of the several underwriters (the “Underwriters”) for net proceeds of $102.3 million. At the closing, the Company issued 4,700,855 shares of common stock, inclusive of 427,351 shares of common stock issued pursuant to the full exercise of the Underwriters’ option to purchase additional shares of common stock. The Company used the net proceeds for the redemption of the Series A Convertible Preferred Stock. Treasury Stock Prior to 2021, the Company held 795,779 shares in Treasury. In the second quarter of 2021, the entire balance of Treasury Stock was sold in the underwritten public offering. Any related additional paid in capital and par values were removed from the common stock numbers. Treasury Stock balance is nil as of December 31, 2023. Preferred Stock The Board of Directors is authorized to issue preferred shares and has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of preferred stock. Series B Non-Convertible Preferred Stock On June 30, 2021, the Company closed a private placement of 75,000 shares of its Series B Perpetual Non-Convertible Preferred Stock, par value $0.0001 per share, with an initial liquidation preference of $1,000 per share (the “Series B Preferred Stock”), for net proceeds of $72.8 million (the “Series B Transaction”). The sale of the Series B Preferred Stock was pursuant to the Series B Preferred Stock Purchase Agreement, dated as of June 24, 2021 (the “Series B Purchase Agreement”), between the Company and B. Riley Principal Investments, LLC (“BRPI”). In connection with the closing of the Series B Transaction, the Company (i) filed a Certificate of Designation with the State of Delaware setting forth the rights, preferences, privileges, qualifications, restrictions and limitations on the Series B Preferred Stock (the “Series B Certificate”) and (ii) entered into an Investor Rights Agreement with B. Riley Financial, Inc. (“B. Riley Financial”) and BRPI setting forth certain governance and registration rights of B. Riley Financial with respect to the Company. Certificate of Designation of the Series B Preferred Stock The rights, preferences, privileges, qualifications, restrictions and limitations of the shares of Series B Preferred Stock are set forth in the Series B Certificate. Under the Series B Certificate, the holders of the Series B Preferred Stock are entitled to receive, on each share of Series B Preferred Stock on a quarterly basis, an amount equal to the dividend rate, as described in the following sentence, divided by four and multiplied by the then-applicable Liquidation Preference per share of Series B Preferred Stock (collectively, the “Preferred Dividends”). The dividend rate is (1) 9.5% per annum for the period commencing on June 30, 2021 and ending on and including December 31, 2021, (2) 13% per annum for the year commencing on January 1, 2022 and ending on and including December 31, 2022; and (3) 14% per annum for the year commencing on January 1, 2023 and thereafter. The Preferred Dividends will be due in cash on January 1, April 1, July 1 and October 1 of each year (each, a “Series B Dividend Payment Date”). The Company may choose to pay the Series B Preferred Dividends in cash or in additional shares of Series B Preferred Stock. In the event the Company does not declare and pay a dividend in cash on any Series B Dividend Payment Date, the unpaid amount of the Preferred Dividend will be added to the Liquidation Preference. As of December 31, 2023, the Liquidation Value and Redemption Value of the Series B Preferred Shares was $63.0 million. Each share of Series B Preferred Stock is redeemable at the option of the holder upon the occurrence of a “Fundamental Change” at (i) par in the case of a payment in cash or (ii) 1.5 times par in the case of payment in shares of Common Stock (such shares being, “Registrable Securities”), subject to certain limitations on the amount of stock that could be issued to the holders of Series B Stock. In addition, the Company will be permitted to redeem outstanding shares of the Series B Preferred Stock at any time for the sum of the then-applicable Liquidation Preference and the accrued but unpaid dividends. Pursuant to the Series B Certificate, the Company will be required to use (i) the first $50.0 million of proceeds from certain transactions (i.e., disposition, sale of assets, tax refunds) received by the Company to redeem for cash, shares of the Series B Preferred Stock, on a pro rata basis among each holder of Series B Preferred Stock and (ii) the next $25.0 million of proceeds from certain transactions received by the Company may be used by the Company to buy back shares of Common Stock and to the extent, not used for such purpose by the Company, to redeem, for cash, shares of the Series B Preferred Stock, on a pro rata basis among each holder of the Series B Preferred Stock. The Company is required to obtain the prior written consent of the holders holding at least a majority of the outstanding shares of the Series B Preferred Stock before taking certain actions, including: (i) certain dividends, repayments and redemptions; (ii) any amendment to the Company’s certificate of incorporation that adversely affects the rights, preferences, privileges or voting powers of the Series B Preferred Stock; and (iii) issuances of stock ranking senior or equivalent to shares of the Series B Preferred Stock (including additional shares of the Series B Preferred Stock) in the priority of payment of dividends or in the distribution of assets upon any liquidation, dissolution or winding up of the Company. Other than with respect to the foregoing consent rights, the Series B Preferred Stock is non-voting stock. Investor Rights Agreement On June 30, 2021, the Company, B. Riley Financial and BRPI entered into an Investor Rights Agreement (the “Investor Rights Agreement”). Pursuant to the Investor Rights Agreement, for so long as affiliates of B. Riley Financial beneficially own at least 10% of the outstanding shares of common stock (unless such equity threshold percentage is not met due to dilution from equity issuances), B. Riley Financial is entitled to nominate one Class II director (the “B. Riley Nominee”) to the Company’s board of directors (the “Board”), who shall be an employee of B. Riley Financial or its affiliates and is approved by the Board, such approval not to be unreasonably withheld. For so long as affiliates of B. Riley Financial beneficially own 5% or more but less than 10% of the outstanding shares of common stock (unless such equity threshold percentage is not met due to dilution from equity issuances), B. Riley Financial is entitled to certain board observer rights.

Share-Based Payment Arrangement [Abstract]
Stock Plans	Stock Plans In March 2015, the Company adopted the 2015 Equity Incentive Plan (the “2015 Plan”). The 2015 Plan replaces the Company’s prior 2000 Equity Incentive Plan and the 2006 Equity Incentive Plan. Beginning March 2015, all awards were granted under the 2015 Plan. In addition, any awards that were previously granted under any prior Plans that terminate without issuance of shares, shall be eligible for issuance under the 2015 Plan. Under the 2015 Plan, the Company may grant to its employees, outside directors and consultants awards in the form of non-qualified stock options, shares of restricted stock, stock units, or stock appreciation rights and performance shares. The Company’s Board of Directors administers the Plan and is responsible for determining the individuals to be granted options or shares, the number of options or shares each individual will receive, the price per share and the exercise period of each option. The maximum number of shares of common stock authorized for issuance under the 2015 Plan is 4,688,576 shares as of December 31, 2023. On December 15, 2017, the Compensation Committee adopted the 2017 New Hire Equity Incentive Plan (“2017 Plan”), which is intended to be exempt from the stockholder approval requirements under the “inducement grant exception” provided by the Inducement Rule. The Committee authorized the issuance of stock grants to new hires, with the purpose of promoting the long-term success of the Company and the creation of stockholder value by (a) providing for the attraction and retention of new employees with exceptional qualifications, (b) encouraging new employees to focus on critical long-range objectives, and (c) linking new employees directly to stockholder interests through increased stock ownership. As required by the Inducement Rule, the Company issues a press release promptly upon issuing shares to new employees pursuant to the 2017 Plan. The maximum number of shares of common stock authorized for issuance under the 2017 Plan is 229,635 shares as of December 31, 2023. As of December 31, 2023, there were 0.7 million shares available for the grant or award under the Company’s 2015 Plan and 0.1 million shares available for the grant or award under the Company’s 2017 Plan. The Company’s performance based cash units granted to employees under the Long Term Incentive (“LTI”) Plans have been accounted for as liability awards, due to the Company’s intent and the ability to settle such awards in cash upon vesting and has reflected such awards in accrued expenses on the Condensed Consolidated Balance Sheet. As of December 31, 2023, the liability for such awards is approximately $0.4 million. Stock-Based Compensation The following table summarizes stock-based compensation expense related to all of the Company’s stock awards included by operating expense categories, as follows: Year Ended December 31, 2023 2022 2021 Cost of revenues $ 109 $ 249 $ 719 Research and development 1,291 1,472 2,313 Selling, general and administrative 2,990 2,743 4,529 Total stock-based compensation expense $ 4,390 $ 4,464 $ 7,561 The following table summarizes stock-based compensation expense related to all of the Company’s stock awards included by award types, as follows: Year Ended December 31, 2023 2022 2021 Stock options $ 1,334 $ 1,981 $ 3,061 Restricted stock awards 2,930 2,500 4,356 Performance based cash units 126 (17) 144 Total stock-based compensation before taxes $ 4,390 $ 4,464 $ 7,561 Tax benefit $ 958 $ 938 $ 1,541 The total stock-based compensation cost related to unvested equity awards as of December 31, 2023 was approximately $4.0 million. The expense is expected to be recognized over a weighted-average period of approximately 0.7 years. The total stock-based compensation cost related to unvested performance-based cash units as of December 31, 2023 was approximately $0.2 million. The expense is expected to be recognized over a weighted-average period of approximately 1.2 years. Stock Options Stock options that were granted under the Company’s Plans generally vest one-third of the shares on the first, second and third anniversary of the grant date subject to optionee’s continuous service. Other than as set forth in Note 15. Capital Structure, there were no significant changes to the Company’s Stock Option Plans during the year ended December 31, 2023.

The total intrinsic value of stock options exercisable as of December 31, 2023 and 2022 was nil and nil, respectively. Awards of Restricted Stock and Performance Stock Restricted stock awards (“Restricted Stock”) granted under the Company’s Plans generally vest one-third of the applicable shares on the first, second, and third anniversary of the date of grant, subject to continuous service provided. Generally, performance stock awards granted under the Company’s 2015 Plan vest at the end of a three-year period based on service and achievement of certain performance objectives determined by the Company’s Board of Directors.

Income Taxes	Income Taxes The components of (loss) income from continuing operations before income taxes are as follows: Year Ended December 31, 2023 2022 2021 Domestic $ (48,967) $ (34,752) $ (53,746) Foreign 19,656 27,974 16,694 Total $ (29,311) $ (6,778) $ (37,052) The components of income tax (expense) benefit from continuing operations are as follows: Year Ended December 31, 2023 2022 2021 Current: Federal $ (1,114) $ (1,159) $ 6,443 State (67) (62) (65) Foreign (821) 1,139 635 Deferred: Federal (2,747) (26) (26) State 3 157 (21) Foreign 3 10 1,821 Income tax (provision) benefit $ (4,743) $ 59 $ 8,787 The Company recognized approximat ely $4.7 million in relat ed income tax expense and $0.1 million in related income tax benefit during the years ended December 31, 2023 and 2022, respectively. The effective tax rate was approximately (16.2)% for the year ended December 31, 2023, which was lower than the U.S. federal statutory rate primarily due to the impact of Global Intangible Low-Taxed Income, attributable to income in foreign jurisdictions and the impact of the U.S. capitalization of research expenses, and the impact of recognizing a deferred tax liability associated with changes in management’s indefinite reinvestment assertion under APB 23 for one foreign jurisdiction. This decrease was partially offset by loss jurisdictions where full valuation allowances have been recorded, foreign rate differential and GAAP to statutory adjustments. The Company’s effective tax rate was approximately 0.9% for the year ended December 31, 2022, which was lower than the U.S. federal statutory rate primarily due to the impact of Global Intangible Low-Taxed Income, attributable to income in foreign jurisdictions and the impact of the U.S. capitalization of research expenses, and the divestiture of the DXP and Activation assets. This decrease was partially offset by loss jurisdictions where full valuation allowances have been recorded and foreign income tax credits generated in the period. Reconciliations of the statutory tax rates and the effective tax rates from continuing operations for the years ended December 31, 2023, 2022 and 2021 are as follows: Year Ended December 31, 2023 2022 2021 Statutory rate 21.0 % 21.0 % 21.0 % State taxes, net of federal benefit (0.2) % 0.8 % (0.3) % Effect of rates different than statutory 4.2 % 30.2 % 3.9 % Minority interest — % 0.6 % (0.1) % Stock based compensation (1.9) % (14.5) % (4.1) % Foreign basis differences 5.0 % 16.1 % 5.4 % Regulatory matters — % — % (7.1) % Other permanent adjustments (3.3) % (3.3) % (2.2) % Withholding tax (2.8) % — % — % Federal and foreign tax credits 0.6 % 1.6 % 0.3 % Change in valuation allowance 4.8 % 89.2 % 9.0 % Uncertain tax positions 0.1 % (2.3) % (3.5) % Other — % (0.1) % (0.4) % Divestiture of assets — % (17.6) % — % Global intangible low-taxed income (20.5) % (131.3) % (9.8) % NOL carryback and other refund claims — % — % 11.6 % Deferred tax adjustments (1.1) % 2.2 % — % Return to provision (1.2) % 8.3 % — % ABP 23 liability (20.9) % — % — % Effective tax rate (16.2) % 0.9 % 23.7 % Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows: As of December 31, 2023 2022 Deferred tax assets: Accrued liabilities $ 486 $ 935 Deferred revenue — 824 Bad debts reserve 3,163 2,219 Deferred compensation 4,150 4,164 Federal net operating loss carry forwards 4,271 4,871 State net operating loss carry forwards 8,641 8,771 Foreign net operating loss carry forwards 4,999 7,030 Lease obligations 5,706 6,509 Capital loss carry forwards 7,633 5,449 Intangible assets 1,470 2,392 Basis difference 6,372 6,454 Credits 3,331 7,815 Fixed assets 639 732 Interest limitation 1,088 32 Capitalization of research expenses 21,805 12,155 Other 33 233 Total deferred tax assets $ 73,787 $ 70,585 Deferred tax liabilities: Unrepatriated Earnings $ (6,604) $ — Basis difference (2,078) (2,880) Depreciation and amortization (666) (709) Prepaids (323) (466) Lease assets (2,524) (3,470) Other (734) (497) Total deferred tax liabilities (12,929) (8,022) Less: valuation allowance (64,065) (63,029) Net deferred income tax (liabilities) assets $ (3,207) $ (466) As of December 31, 2023, the Company has federal and state income tax net operating loss (“NOL”) carryforwards of $20.3 million and $148.9 million, respectively, including NOL carryforwards which will expire at various dates from 2025 through 2041, and NOL carryforwards which do not expire. The Company also has foreign NOL carryforwards in various jurisdictions of $36.5 million that have various carryforward periods. Such NOL carryforwards expire as follows: Year NOL carryforward 2024 $ — 2025 445 2026-2041 169,612 Indefinite 35,683 Total $ 205,740 As of December 31, 2022, the Company has federal and state income tax credit carryforwards of $2.2 million and $1.5 million, respectively, including state credits of approximately $0.4 million which will expire in 2024, other credits which will expire at various dates from 2025 through 2039 and credits which do not expire. In evaluating the Company’s ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, the Company begins with historical results and incorporates assumptions including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates the Company is using to manage the underlying businesses. The foreign NOL carryforwards in the income tax returns filed included unrecognized tax benefits taken in prior years. The NOLs for which a deferred tax asset is recognized for financial statement purposes in accordance with ASC 740 are presented net of these unrecognized tax benefits. The Company continues to evaluate the ability to realize all of its net deferred tax assets at each reporting date and records a benefit for deferred tax assets to the extent it has deferred tax liabilities that provide a source of income to benefit the deferred tax asset. As a result of this analysis, the Company recorded a valuation allowance against the net deferred tax assets of certain foreign jurisdictions as the realization of these assets is not more likely than not, given uncertainty of future earnings in these jurisdictions. The valuation allowance increased by $1.0 million during the year ended December 31, 2023 and decreased by $5.9 million during the year ended December 31, 2022, respectively. The increase in tax year ended December 31, 2023 is primarily related to an increase in deferred tax assets including capital loss carryforward, interest expense limitation and capitalization of research expenditures, net of utilization of tax credit and net operating loss carryforwards. This increase was partially offset by an increase in deferred tax liabilities primarily associated with changes in management’s indefinite reinvestment assertion under APB 23 for one foreign jurisdiction. The decrease in tax year ended December 31, 2022 is primarily related to a decrease in deferred tax assets including deferred revenue, intangibles and net operating loss, interest expense and tax credit carryforwards, net of capitalization of research expenditures. This decrease was partially offset by a decrease in deferred tax liabilities primarily associated with intangible assets during the period. The Company's accounting policy is to record the tax impacts of Global Intangible Low-Taxed Income as a period cost. The Company’s current accounting policy related to stranded tax effects in accumulated other comprehensive income is to review and reclassify on an item-by-item basis. The Company is subject to taxation in the United States and various states and foreign jurisdictions. As of December 31, 2023, the Company’s tax years for 2020 through 2023 are subject to examination by the tax authorities. With few exceptions, as of December 31, 2023, the Company is no longer subject to U.S. federal, state, local, or foreign examinations by tax authorities for years before 2020. Additionally, to the extent we utilize our NOL carryforwards in the future, the tax years in which the attribute was generated may still be adjusted upon examination by the tax authorities in the future period when the attribute is utilized. During 2021 the Internal Revenue Service commenced an audit of certain of the Company’s prior year U.S. federal income tax filings, including the 2013 through 2020 tax years. The audit is currently ongoing and while receipt of the associated refunds would materially improve its financial position, the Company does not believe that the results of this audit will have a material effect on its financial position or results of operations. Due to the ongoing audit, U.S. federal tax returns for years 2013 – 2020 remain subject to future examination by the tax authorities. The Company received $4.3 million in federal tax refunds in the second quarter of 2022. There is no change to the Company’s position on the remaining tax refunds. Our policy has been to leave our cumulative unremitted foreign earnings invested indefinitely outside the United States, and we intend to continue this policy for most of our foreign subsidiaries. During 2023, we changed our indefinite reinvestment assertion for our Indian subsidiary and recorded a deferred tax liability associated with the outside basis difference. The Company continues to assert permanent reinvestment of foreign earnings in all other foreign jurisdictions. Due to the timing and circumstances of repatriation of such earnings, if any, it is not practicable to determine the unrecognized deferred tax liability relating to such amounts. In March 2020, in response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses. The CARES Act amends the Net Operating Loss provisions of the Tax Cuts and Jobs Act, allowing for the carryback of losses arising in tax years 2018, 2019 and 2020, to each of the five taxable years preceding the taxable year of loss. On October 8, 2021, the Organization for Economic Co-operation and Development (“OECD”) released a statement on the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting, which agreed to a two-pillar solution to address tax challenges of the digital economy. On December 20, 2021, the OECD released Pillar Two model rules defining a 15% global minimum tax rate for large multinational corporations (the “Pillar Two Framework”). The OECD continues to release additional guidance and countries are implementing legislation with widespread adoption of the Pillar Two Framework expected by 2024. The Company is not currently subject to these rules but is continuing to evaluate the Pillar Two Framework and its potential impact on future periods. On March 11, 2021 the American Rescue Plan Act ("ARPA") was signed into law. The legislation was aimed at addressing the continuing economic and health impacts of the COVID-19 pandemic. This legislative relief, along with the previous governmental relief packages provide for numerous changes to current tax law. ARPA does not materially impact the Company’s financial statements. On August 16, 2022, the Inflation Reduction Act of 2022 ("IRA") was signed into law. This legislation includes significant changes relating to tax, climate change, energy and health care. Among other provisions, the IRA introduces a book minimum tax assessed on financial statement income of certain large corporations and an excise tax on share repurchases. The Company does not anticipate these provisions will have a material impact on our results of operations or financial position, when effective. On January 31, 2024, the House of Representatives passed a proposed tax bill which, among other provisions, aims to reinstate 100% bonus depreciation for property placed in service in 2023 and through 2025 and to allow taxpayers to expense domestic research costs retroactively back to 2022 and prospectively through tax years beginning before 2026. Enactment remains uncertain and the Company continues to monitor the ongoing developments in the proposed legislation. A reconciliation of the amounts of unrecognized tax benefits excluding interest, are as follows: Unrecognized tax benefits Balance at December 31, 2020 $ 3,283 Decrease related to lapse of Statute of Limitations (827) Increase for tax positions of current period 2,058 Balance at December 31, 2021 4,514 Decrease related to lapse of Statute of Limitations (1,043) Increase for tax positions of current period 966 Balance at December 31, 2022 4,437 Decrease related to lapse of Statute of Limitations (64) Balance at December 31, 2023 $ 4,373 Included in the balance of unrecognized tax benefits associated with uncertain tax positions as of the years ended December 31, 2023 and 2022, are $3.8 million and $3.9 million, respectively, of tax benefits that, if recognized, would affect the effective tax rate. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in interest expense. The liability for unrecognized tax benefits excludes accrued interest of $0.7 million, $0.4 million and $0.4 million, for the years ended December 31, 2023 , 2022 and 2021, respectively. The Company does not believe that it is reasonably possible that any of its currently unrecognized tax benefits primarily related to research and development credits and other U.S. tax positions, may be recognized by the end of 2024 as a result of a lapse of the statute of limitations.

Earnings Per Share [Abstract]
Earnings per Common Share (“EPS”)	Earnings per Common Share (“EPS”) Basic EPS is computed based upon the weighted average number of common shares outstanding for the year. Diluted EPS is computed based upon the weighted average number of common shares outstanding for the year plus the dilutive effect of common stock equivalents using the treasury stock method and the average market price of the Company’s common stock for the year. The Company includes participating securities (Redeemable Convertible Preferred Stock - Participation with Dividends on Common Stock that contain preferred dividend) in the computation of EPS pursuant to the two-class method. The two-class method of computing earnings per share is an allocation method that calculates earnings per share for common stock and participating securities. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company. The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income attributable to common stockholders per common share from operations.

Commitments and Contingencies Disclosure [Abstract]
Legal Matters	Legal Matters In the ordinary course of business, the Company is regularly subject to various claims, suits, regulatory inquiries and investigations. The Company records a liability for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable, and the loss can be reasonably estimated. Management has also identified certain other legal matters where they believe an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against the Company, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the Company’s business, financial position, results of operations, or cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. In the third quarter of 2017, the SEC and Department of Justice (the “DoJ”) initiated investigations in connection with certain financial transactions that the Company effected in 2015 and 2016 and its disclosure of and accounting for such transactions, which the Company restated in the third quarter of 2018 in its restated annual and quarterly financial statements for 2015 and 2016. On June 7, 2022 the SEC approved the Offer of Settlement and filed an Order Instituting Cease-And-Desist Proceedings pursuant to Section 21C of the Securities Exchange Act of 1934, Making Findings, and Imposing a Cease-And-Desist Order (the “SEC Order”). Pursuant to the terms of the SEC Order, the Company consented to pay a civil penalty in the amount of $12.5 million in equal quarterly installments over two years and to cease and desist from committing or causing any violations of Sections 10(b), 13(a), 13(b)(2)(A) and 13(b)(2)(B) of the Exchange Act and the associated rules thereunder. In addition, failure to comply with the provisions of the SEC Order could result in further actions by one or both governmental agencies which could have a material adverse effect on the Company’s results of operations. The expense associated with this settlement of the SEC Order has previously been accrued in the Company’s financial statements. Also on June 7, 2022, the SEC filed a civil action against two former members of the Company’s management team, alleging misconduct arising out of the restated transactions that took place in 2015 and 2016 investigated by the SEC as set forth above. The Company may be required to indemnify the former members of management in that action for certain costs and expenses, including reasonable attorney’s fees. At this time it is not possible for us to estimate the amount, if any, of such indemnification obligations. On or about July 12, 2023, the Company filed a complaint in the Superior Court of the State of Delaware against iQmetrix Global Ltd. (“iQmetrix") for breach of the asset purchase and transition services agreements by and between the Company and iQmetrix as a result of iQmetrix’s failure to pay amounts due under those agreements in excess of $1,200,000. On September 11, 2023, iQmetrix filed its “Answer Defenses and Counterclaims” against the Company, claiming the Company breached the asset purchase, transition services and software license agreements, committed fraud and breached the implied covenant of good faith and fair dealing entitling iQmetrix to an amount to be determined at trial. On October 10, 2023, the Company filed its “Answer to Defendant’s Counterclaims” denying all counts asserted by iQmetrix and asserting certain affirmative defenses thereto. The Company believes that the counterclaims are without merit, and the Company intends to defend all such counterclaims. Due to the inherent uncertainty of litigation, the Company cannot predict the outcome of the litigation and can give no assurance that the asserted claims will not have a material adverse effect on its financial position, prospects, or results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Discontinued Operations	On October 31, 2023, Synchronoss Technologies, Inc. entered into an Asset Purchase Agreement with Lumine Group Software Solutions (Ireland) Limited, pursuant to which the Company sold its Messaging and NetworkX businesses. This transaction represents a strategic shift designed to maximize shareholder value and allow the Company to solely focus on providing cloud-centric solutions. In connection with the sale transaction, the Company determined its Messaging and NetworkX Businesses qualified for discontinued operations accounting treatment in accordance with ASC 205-20. Accordingly, the operating results of, and costs to separate the Messaging and NetworkX businesses are reported in Net loss from discontinued operations, net of taxes in the Consolidated Statements of Operations for all periods presented. In addition, the related assets and liabilities held prior to the sale are reported as Assets and liabilities of discontinued operations on the Consolidated Balance Sheets. The notes to the financial statements have been adjusted on a retrospective basis. For additional information, see Note 4. Divestitures and Discontinued Operations of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary and entities in which the Company has a controlling interest. Investments in less than majority-owned companies in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. Investments in less than majority-owned companies in which the Company does not have the ability to exert significant influence over the operating and financial policies of the investee are accounted for using the cost method. All material intercompany transactions and accounts are eliminated in consolidation. Unless otherwise noted, tables are presented in U.S. dollars in thousands. Certain columns and rows may not add due to the use of rounded numbers. Percentages presented are calculated from the underlying numbers in thousands. Earnings per share amounts are computed independently for earnings from continuing operations, earnings from discontinued operations and net earnings. As a result, the sum of per-share amounts may not equal the total. Unless otherwise noted, all amounts and disclosures included in the Notes to Consolidated Financial Statements reflect only the Company's continuing operations except for the Consolidated Statements of Cash Flows, which are presented for the whole company. For supplemental cash flow disclosures, see Note 4. Divestitures and Discontinued Operations of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K. During the fourth quarter of 2023 there was a change in the capital structure due to a reverse stock split, which decreased the number of common shares outstanding. The Company retroactively displayed the effect of the change in the Consolidated Balance Sheets, and retroactively adjusted the computations of basic and diluted EPS for all periods presented on the Consolidated Statement of Operations. For additional information, see Note 15. Capital Structure of the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K.
Risks and Uncertainties	Risks and Uncertainties There continue to be uncertainties regarding the current geopolitical tensions. The Company is closely monitoring the impact of the geopolitical environment on all aspects of its business, including how it will impact its customers, employees, suppliers, vendors, business partners and distribution channels. While the geopolitical environment did not materially affect the Company’s financial results and business operations for the year ended December 31, 2023, the Company is unable to predict the impact these factors will have on its financial position and operating results due to numerous uncertainties. The Company will continue to assess the evolving impact of geopolitical tensions and will make adjustments to its operations as necessary.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Standards issued not yet adopted Standard Description Effect on the financial statements Update 2023-09 - Income Taxes (Topic 740) - Improvements to Income Tax Disclosures The amendments in this Update related to the rate reconciliation and income taxes paid disclosures improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. The Company continues to evaluate these changes and does not anticipate any material impact on the Company’s consolidated financial position or results of operations upon adoption. Planned date of adoption: January 1, 2025 Update 2023-07 - Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures The amendments in this Update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this Update Requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this Update and all existing segment disclosures in Topic 280. The Company continues to evaluate these changes and does not anticipate any material impact on the Company’s consolidated financial position or results of operations upon adoption. Planned date of adoption: January 1, 2024
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Revenues are recognized when control of the promised goods or services are transferred to the Company’s customers, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company generates all of its revenue from contracts with customers. Subscription and Transaction revenues consist of revenues derived from the processing of transactions through the Company’s service platforms, providing enterprise portal management services on a subscription basis and maintenance agreements on software licenses. The Company generates revenue from Subscription services from monthly active user fees, software as a service (“SaaS”) fees, hosting and storage fees, and fees for the related maintenance support for those services. In most cases, the subscription or transaction arrangement is a single performance obligation comprised of a series of distinct services that are substantially the same and that have the same pattern of transfer (i.e., distinct days of service). The Company applies the variable consideration allocation exception when the terms of variable payment relate specifically to efforts to satisfy the performance obligation or the transfer of service based on usage within the corresponding period, under Topic 606 Section 10-25-14(b) – in such situations the revenue booked and the revenue billed for any month are the same. When the Company does not allocate variable consideration to distinct periods of service or apply the variable consideration allocation exception, the total estimated transaction price is recognized ratably over the term of the contract, where the level of service provided to the customer does not vary significantly from one period to another. Transaction service arrangements include services such as processing equipment orders, new account setup and activation, number port requests, credit checks and inventory management. Transaction revenues are principally based on a contractual price per transaction and are recognized based on the number of transactions processed during each reporting period. Revenues are recorded based on the total number of transactions processed at the applicable price established in the relevant contract. Many of the Company’s contracts guarantee minimum volume transactions from the customer. In these instances, if the customer’s total estimated transaction volume for the period is expected to be less than the contractual amount, the Company records revenues at the minimum guaranteed amount ratably over the period covered by the minimum. Setup fees for transactional service arrangements are deferred until set up activities are completed and recognized on a straight‑line basis over remaining expected customer relationship period. Revenues are presented net of discounts, which are volume level driven. In accordance with Topic 606 Section 10-50-20, any credits due to customers, which are generally performance driven and based upon system availability or response times to incidents, are determined and accounted for as a reduction to revenue in the period in which the services are provided. The Company recognizes revenues from support and maintenance performance obligations over the service delivery period. The Company’s software licenses typically provide for a perpetual or term right to use the Company’s software. The Company has concluded that in most cases its software license is distinct as the customer can benefit from the software on its own. Software revenue is typically recognized when the software is delivered to the customer. Contracts that include software customization or specified upgrades may result in the combination of the customization services with the software license as one performance obligation. The Company does not have a history of returns, or refunds of is software licenses, however, in limited instances, the Company may constrain consideration to high-risk customers, until collection is resolved. The Company’s professional services include software development and customization. The contracts generally include project deliverables specified by each customer. The performance obligations in the agreements are generally combined into one deliverable and generally result in the transfer of control over time. The underlying deliverable is owned and controlled by the customer and does not create an asset with an alternative use to us. The Company recognizes revenue on fixed fee contracts on the proportion of labor hours expended to the total hours expected to complete the contract performance obligation, or ratably to the extent the level of effort to satisfy the performance obligation is materially consistent each period. Most of the Company’s contracts with customers contain multiple performance obligations which generally include either 1) a perpetual software license with support and maintenance and sometimes a hosting agreement or 2) a term SaaS agreement, frequently sold along with professional services. For these contracts, the Company accounts for individual goods and services separately if they are distinct performance obligations. This often requires significant judgment based upon knowledge of the products, the solution provided and the structure of the sales contract. In SaaS agreements, the Company provides a service to the customer which combines the software functionality, maintenance and hosting into a single performance obligation when the customer doesn’t have the ability to take possession of the underlying software license. The Company may also sell the same three goods and services in a contract, but there may be three performance obligations, where the customer has the right to take possession of the software license without significant penalty. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. The Company estimates standalone selling prices of software based on observable inputs of past transactions to similarly situated customers. When such observable data is not available for certain software licenses because there is a limited number of transactions or prices are highly variable, the Company will estimate the standalone selling price using the residual approach. Standalone selling prices of services are typically determined based on observable transactions when these services are sold on a standalone basis to similarly situated customers or estimated using a cost-plus margin approach. Estimating the transaction price of variable consideration including the variable quantity subscription or transaction contracts in a multiple performance obligation arrangement requires significant judgment. The Company generally estimates this variable consideration at the most likely amount to which the Company expects to be entitled and in certain cases based on the expected value. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information (historical, current and forecasted) that is reasonably available. The Company reviews and updates these estimates on a quarterly basis. The Company’s typical performance obligations include the following: Performance Obligation When Performance Obligation is Typically Satisfied How Standalone Selling Price is Typically Estimated Software License Software License Upon shipment or made available for download (point in time) Observable transactions or residual approach when prices are highly variable or uncertain Software License with significant customization Over the performance of the customization and installation of the software (over time) Residual approach Hosting Services As hosting services are provided (over time) Estimated using a cost-plus margin approach Professional Services Consulting As work is performed (over time) Observable transactions Customization SaaS: Over the remaining term of the SaaS agreement License: Over the performance of the customization and installation of the software (over time) Observable transactions Transaction Services As transaction is processed (over time) Observable transactions Subscription Services Customer Support Ratably over the course of the support contract (over time) Observable transactions SaaS Over the course of the SaaS service once the system is available for use (over time) Estimated using a cost-plus margin approach The payments for the Company’s performance obligations are typically due within 90 days of services being provided for Software License, Professional Services, and Subscription Services, and due within 90 days of transaction for Transaction Services. Deferred Revenue Deferred revenues represent billings to customers for services in advance of the performance of services, with revenues recognized as the services are rendered. Service Level Standards Pursuant to certain contracts, the Company is subject to service level standards and to corresponding penalties for failure to meet those standards. All performance-related penalties are reflected as a corresponding reduction of the Company’s revenues. These penalties, if applicable, are recorded in the month incurred and were insignificant for the years ended December 31, 2023, 2022 and 2021, respectively.
Cost of Revenues	Cost of Revenues Cost of services includes all direct materials, direct labor and those indirect costs related to revenues such as indirect labor, materials and supplies and facilities cost, exclusive of depreciation and amortization expense.
Research and Development	Research and Development Software development costs are accounted for in accordance with either ASC 985-20, “Software - Costs of Software to be Sold, Leased or Marketed,” or ASC 350-40, “Internal-Use Software.” Costs associated with the planning and designing phase of software development are classified as research and development costs and are expensed as incurred. The amounts capitalized include external direct costs of services used in developing internal-use software, and employee compensation and related expenses of personnel directly associated with the development activities. Once technological feasibility has been determined, a portion of the costs incurred in development, including coding, testing and quality assurance, are capitalized until available for general release to clients. Amortization is calculated on a solution-by-solution basis and is recognized over the estimated economic life of the software, typically ranging two

Concentration of Credit Risk	Concentration of Credit Risk The Company’s financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents at several major financial institutions. The Company believes that concentration of credit risk with respect to accounts receivable is limited because of the creditworthiness of its major customers.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of acquisition to be cash equivalents.
Accounts Receivable	Accounts Receivable
Allowance for Credit Losses	Allowance for Credit Losses The Company is exposed to credit losses primarily through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Customers are pooled based on sharing specific risk factors, including geographic location. Due to the short-term nature of such receivables, the estimated accounts receivable that may not be collected is based on aging of the accounts receivable balances.
Fair Value of Financial Instruments and Liabilities	Fair Value of Financial Instruments and Liabilities The Company includes disclosures of fair value information about financial instruments and liabilities, whether or not recognized on the Consolidated Balance Sheets, for which it is practicable to estimate that value. Due to their short-term nature, the carrying amounts reported in the financial statements approximate the fair value for cash and cash equivalents, marketable securities, accounts receivable and accounts payable. In accordance with accounting principles generally accepted in the United States, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy prioritizes the inputs used to measure fair value as follows: • Level 1 - Observable inputs - quoted prices in active markets for identical assets and liabilities; • Level 2 - Observable inputs other than the quoted prices in active markets for identical assets and liabilities includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and • Level 3 - Unobservable inputs - includes amounts derived from valuation models where one or more significant inputs are unobservable and require the Company to develop relevant assumptions.
Property and Equipment	Property and Equipment Property and equipment and leasehold improvements are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 5 years, or the lesser of the related initial term of the lease or useful life for leasehold improvements. Amortization of property and equipment recorded under a capital lease is included with depreciation expense. Expenditures for routine maintenance and repairs are charged against operations, while major replacements, improvements and additions are capitalized.
Noncontrolling Interests and Mandatorily Redeemable Financial Instruments	Noncontrolling Interests and Mandatorily Redeemable Financial Instruments Noncontrolling interests (“NCI”) are evaluated by the Company and are shown as either a liability, temporary equity (shown between liabilities and equity) or as permanent equity depending on the nature of the redeemable features at amounts based on formulas specific to each entity. Generally, mandatorily redeemable NCIs are classified as liabilities and non-mandatorily redeemable NCIs are classified outside of stockholders’ equity in the Consolidated Balance Sheets as temporary equity under the caption Redeemable noncontrolling interests, and are measured at their redemption values at the end of each period. If the redemption value is greater than the carrying value, an adjustment is recorded in retained earnings to record the NCI at its redemption value. Redeemable NCIs that are mandatorily redeemable are classified as a liability in the Consolidated Balance Sheets under either other current liabilities or other long-term liabilities, depending on the remaining duration until settlement, and are measured at the amount of cash that would be paid if settlement occurred at the balance sheet date with any change from the prior period recognized as interest expense. If the noncontrolling interest is not currently redeemable yet probable of becoming redeemable, the Company is required to either (1) accrete changes in the redemption value over the period from the date of issuance to the earliest redemption date of the instrument using an appropriate methodology, usually the interest method, or (2) recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of each reporting period. The Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the noncontrolling interest to the greater of the estimated redemption value, which approximates fair value, at the end of each reporting period or the initial carrying amount. Net income attributable to NCIs reflects the portion of the net income (loss) of consolidated entities applicable to the NCI stockholders in the accompanying Consolidated Statements of Operations. The net income attributable to NCI is classified in the Consolidated Statements of Operations as part of consolidated net income and deducted from total consolidated net income to arrive at the net income attributable to the Company.
Investments in Affiliates and Other Entities	Investments in Affiliates and Other Entities In the normal course of business, Synchronoss enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by Synchronoss in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. Synchronoss determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if Synchronoss is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When Synchronoss is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest. The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over and holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for using the cost method unless the investment had a readily determinable fair value, at which it would then be reported. If an entity fails to meet the characteristics of a VIE, the Company then evaluates such entity under the voting model. Under the voting model, the Company consolidates the entity if they determine that they, directly or indirectly, have greater than 50% of the voting shares, and determine that other equity holders do not have substantive participating rights.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including other definite-lived intangible assets. Goodwill is reviewed for impairment annually in the fourth quarter or when an interim triggering event has occurred indicating potential impairment. The Company has concluded that it has one operating segment and one reporting unit. The Company tests for goodwill impairment on its reporting unit. During the Company’s qualitative assessment, the Company makes significant estimates, assumptions, and judgments, around the financial performance of the Company, changes in share price, and forecasts of earnings, working capital requirements, and cash flows. The Company considers each reporting unit's historical results and operating trends as well as any strategic difference from the Company’s historical results when determining these assumptions. The Company can opt to perform a qualitative assessment to test a reporting unit’s goodwill for impairment or the Company can directly perform the quantitative impairment test. If the Company determines that the fair value of a reporting unit is more likely than not to be less than its carrying amount, a quantitative impairment test is performed. Fair value estimates used in the quantitative impairment test are calculated using a combination of the income and market approaches. The income approach is based on the present value of future cash flows of each reporting unit, while the market approach is based on certain multiples of selected guideline public companies or selected guideline transactions. The approaches incorporate a number of market participant assumptions including future growth rates, discount rates, income tax rates and market activity in assessing fair value and are reporting unit specific. If the carrying amount exceeds the reporting unit's fair value, the Company recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The fair value measurement associated with the quantitative goodwill impairment test is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. Significant changes in the underlying assumptions used to value goodwill could significantly increase or decrease the fair value estimates used for impairment assessments. In order to assess the reasonableness of the estimated fair value of the Company’s reporting unit, the Company compares the aggregate reporting unit fair value to the Company’s market capitalization on an overall basis and calculates an implied control premium (the excess of the sum of the reporting units’ fair value over the Company’s market capitalization on an overall basis). The Company evaluates the control premium by comparing it to observable control premiums from recent comparable transactions. If the implied control premium is determined to not be reasonable in light of these recent transactions, the Company re-evaluates its reporting unit fair values, which may result in an adjustment to the discount rate and/or other assumptions. This re-evaluation could result in a change to the estimated fair value of the reporting unit. If the fair value of a reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not impaired. If the fair value of the reporting unit is less than its carrying amount, goodwill is impaired and the excess of the reporting unit’s carrying value over the fair value is recognized as an impairment loss.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets A review of long-lived assets for impairment is performed when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. If an indication of impairment is present, the Company compares the estimated undiscounted future cash flows to be generated by the asset to the asset’s carrying amount. If the undiscounted future cash flows are less than the carrying amount of the asset, the Company records an impairment loss equal to the amount by which the asset’s carrying amount exceeds its fair value. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. This fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. Significant changes in the underlying assumptions used to value long lived assets could significantly increase or decrease the fair value estimates used for impairment assessments. Long lived assets that do not have indefinite lives are amortized/depreciated over their useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The Company reevaluates the useful life determinations each year to determine whether events and circumstances warrant a revision to the remaining useful lives.
Leases	Leases Whenever the Company enters into a new arrangement, it must determine, at the inception date, whether the arrangement contains a lease. This determination generally depends on whether the arrangement conveys to the Company the right to control the use of an explicitly or implicitly identified fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset. If a lease exists, the Company must then determine the separate lease and non-lease components of the arrangement. Each right to use an underlying asset conveyed by a lease arrangement should generally be considered a separate lease component if it both: (i) can benefit the Company without depending on other resources not readily available to the Company and (ii) does not significantly affect and is not significantly affected by other rights of use conveyed by the lease. Aspects of a lease arrangement that transfer other goods or services to the Company but do not meet the definition of lease components are considered non-lease components. The consideration owed by the Company pursuant to a lease arrangement is generally allocated to each lease and non-lease component for accounting purposes. However, the Company has elected to not separate lease and non-lease components. Each lease component is accounted for separately from other lease components, but together with the associated non-lease components. For each lease, the Company must then determine: • The lease term - The lease term is the period of the lease not cancellable by the Company, together with periods covered by: (i) renewal options the Company is reasonably certain to exercise or that are controlled by the lessor and (ii) termination options the Company is reasonably certain not to exercise. • The present value of lease payments is calculated based on: – Lease payments - Lease payments include certain fixed and variable payments, less lease incentives, together with amounts probable of being owed by the Company under residual value guarantees and, if reasonably certain of being paid, the cost of certain renewal options and early termination penalties set forth in the lease arrangement. Lease payments exclude consideration that is: (i) not related to the transfer of goods and services to the Company and (ii) allocated to the non-lease components in a lease arrangement, except for the classes of assets where the Company has elected to not separate lease and non-lease components. – Discount rate - The discount rate must be determined based on information available to the Company upon the commencement of a lease. Lessees are required to use the rate implicit in the lease whenever such rate is readily available; however, as the implicit rate in the Company's leases is generally not readily determinable, the Company generally uses the hypothetical incremental borrowing rate it would have to pay to borrow an amount equal to the lease payments, on a collateralized basis, over a timeframe similar to the lease term. • Lease classification - In making the determination of whether a lease is an operating lease or a finance lease, the Company considers the lease term in relation to the economic life of the leased asset, the present value of lease payments in relation to the fair value of the leased asset and certain other factors, including the lessee's and lessor's rights, obligations and economic incentives over the term of the lease. Generally, upon the commencement of a lease, the Company will record a lease liability and a right-of-use (ROU) asset. However, the Company has elected, for certain classes of underlying assets with initial lease terms of twelve months or less (known as short-term leases), to not recognize a lease liability or ROU asset. Lease liabilities are initially recorded at lease commencement as the present value of future lease payments. ROU assets are initially recorded at lease commencement as the initial amount of the lease liability, together with the following, if applicable: (i) initial direct costs and (ii) lease payments made, net of lease incentives received, prior to lease commencement. Over the lease term, the Company generally increases its lease liabilities using the effective interest method and decreases its lease liabilities for lease payments made. The Company generally amortizes its ROU assets over the shorter of the estimated useful life or the lease term and assesses its ROU assets for impairment, similar to other long-lived assets. For finance leases, amortization expense and interest expense are recognized separately in the Consolidated Statements of Operations, with amortization expense generally recorded on a straight-line basis and interest expense recorded using the effective interest method. For operating leases, a single lease cost is generally recognized in the Consolidated Statements of Operations on a straight-line basis over the lease term. Lease costs for short-term leases not recognized in the Consolidated Balance Sheets are recognized in the Consolidated Statements of Operations and are expensed as incurred. Variable lease costs not initially included in the lease liability and ROU asset impairment charges are expensed as incurred.
Income Taxes	Income Taxes In March 2020, in response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law. The CARES Act provides numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses. The CARES Act amends the Net Operating Loss provisions of the Tax Cuts and Jobs Act, allowing for the carryback of losses arising in tax years 2018, 2019 and 2020, to each of the five taxable years preceding the taxable year of loss. Since we conduct operations on a global basis, our effective tax rate has and will depend upon the geographic distribution of our pre-tax earnings among locations with varying tax rates. We account for the effects of income taxes that result from our activities during the current and preceding years. Under this method, deferred income tax liabilities and assets are based on the difference between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse or be utilized. The realization of deferred tax assets is contingent upon the generation of future taxable income. A valuation allowance is recorded if it is “more likely than not” that a portion or all of a deferred tax asset will not be realized. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. We recognize a tax benefit from an uncertain tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The amount of the accrual for which an exposure exists is measured by determining the amount that has a greater than 50 percent likelihood of being realized upon the settlement of the position. Components of the reserve are classified as current or a long-term liability in the Consolidated Balance Sheets based on when we expect each of the items to be settled. We record interest and penalties accrued in relation to uncertain tax benefits as a component of interest expense. While we believe we have identified all reasonably identifiable exposures and that the reserve we have established for identifiable exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures may be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause us to either materially increase or reduce the carrying amount of our tax reserves. In general, tax returns for the y ear 2018 and thereafter are subject to future examination by tax authorities. Additionally, to the extent we utilize our NOL carryforwards in the future, the tax years in which the attribute was generated may still be adjusted upon examination by the tax authorities in the future period when the attribute is utilized. Our policy has been to leave our cumulative unremitted foreign earnings invested indefinitely outside the United States, and we intend to continue this policy. Although distributions to the U.S. are generally not subject to U.S. federal taxes, the Company continues to assert permanent reinvestment of foreign earnings. Due to the timing and circumstances of repatriation of such earnings, if any, it is not practicable to determine the unrecognized deferred tax liability relating to such amounts.
Foreign Currency Exchange	Foreign Currency Exchange The functional currency of non-U.S. entities is translated into U.S. dollars for balance sheet accounts using the month end rates in effect as of the balance sheet date and average exchange rate for revenue and expense accounts for each respective period. The translation adjustments are deferred as a separate component of stockholders’ equity within accumulated other comprehensive income.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Reporting on comprehensive income requires components of other comprehensive income, including unrealized gains or losses on available-for-sale securities, to be included as part of total comprehensive income. Comprehensive income is comprised of net income, translation adjustments and unrealized gains and losses on available-for-sale securities. The components of comprehensive income are included in the Consolidated Statements of Comprehensive (Loss) Income.
Basic and Diluted Net Income Attributable to Common Stockholders per Common Share	Basic and Diluted Net Income Attributable to Common Stockholders per Common Share Basic EPS is computed based upon the weighted average number of common shares outstanding for the year, excluding amounts associated with restricted shares. Diluted EPS is computed based upon the weighted average number of common shares outstanding for the year plus the potential dilutive effect of common stock equivalents using the treasury stock method and the average market price of the Company’s common stock for the year. The potential dilutive effect of common stock includes stock options, convertible debt and unvested restricted stock. The dilutive effects of stock options and restricted stock awards are based on the treasury stock method. The dilutive effect of the assumed conversion of convertible debt is determined using the if-converted method. The after-tax effect of interest expense related to the convertible securities is added back to net income, and the convertible debt is assumed to have been converted into common shares at the beginning of the period. The Company includes participating securities (Redeemable Convertible Preferred Stock - Participation with Dividends on Common Stock that contain preferred dividend) in the computation of EPS pursuant to the two-class method. The two-class method of computing earnings per share is an allocation method that calculates earnings per share for common stock and participating securities. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.
Stock-based Compensation	Stock-Based Compensation As of December 31, 2023, the Company maintains two stock-based compensation plans. The Company utilizes the Black-Scholes pricing model to determine the fair value of stock options on the dates of grant. Restricted stock awards are measured based on the fair market values of the underlying stock on the dates of grant. The Company recognizes stock-based compensation over the requisite service period with an offsetting credit to additional paid-in capital. For the Company’s performance restricted stock awards and units, the Company estimates the number of shares the recipient is to receive by applying a probability of achieving the performance goals. The actual number of shares the recipient receives is determined at the end of the performance period based on the results achieved versus goals based on the performance targets, such as revenues and earnings before interest, tax, depreciation and amortization (“EBITDA”) after certain adjustments, and Total Shareholder Return (TSR). The compensation cost is recognized using straight line method over the requisite service period for each vesting tranche. Performance based stock awards are measured at the closing stock price on the grant date and are recognized straight line over the requisite service period. Performance based cash units are measured at the closing stock price at the reporting period end date and are recognized straight line over the requisite service period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility was calculated based on historical information of the Company’s stock. The average expected life was determined using historical stock option exercise activity. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The Company has never declared or paid cash dividends on the common equity and does not anticipate paying any cash dividends on the common equity in the foreseeable future. Forfeitures are accounted for as they occur.

Revenue from Contract with Customer [Abstract]
