Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation These Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). Certain prior year amounts have been reclassified for consistency with the current year presentation. Such reclassifications impacted the classification of general and administrative expenses and research and development expenses. These insignificant reclassifications had no effect on the reported results of operations, cash flows, or financial position. Changes in Accounting Policies The Company has consistently applied the accounting policies described in this Note 2 to all periods presented in these Consolidated Financial Statements, except for the Company's adoption of certain accounting standards described in more detail under " Recently adopted accounting pronouncements " in this Note 2 below. Dollar Amounts The dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars, except per share amounts, or as noted within the context of each footnote disclosure. Use of Estimates The preparation of these Consolidated Financial Statements in conformity with GAAP requires the Company to make certain estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses during the reporting period. The complexity and judgment required in the Company's estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in determining the nature and timing of satisfaction of performance obligations and determining the standalone selling price of performance obligations, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for credit losses, the determination of the period of benefit for deferred commissions, operating lease right-of-use assets and operating lease liabilities, useful lives of assets, depreciation and amortization, fair value of assets acquired and liabilities assumed for business combinations, income taxes and deferred tax asset valuation, valuation of stock awards, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. Actual results could differ from those estimates and such differences could be material to the Company's consolidated financial position and results of operations. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase, or the ability to be settled in cash within a period of three months, to be cash equivalents, except for commercial paper which is classified as short-term investments, if any. The Company has a cash management program that provides for the investment of excess cash balances, primarily in short-term money market instruments. Trade and Other Receivables Trade and other receivables are primarily comprised of trade receivables, net of allowance for credit losses, contract assets and unbilled receivables. The Company records trade accounts receivable for its unconditional rights to consideration arising from the Company's performance under contracts with customers. The Company's standard billing terms are generally within thirty to sixty days from the date of the invoice. The carrying value of such receivables, net of the allowance for credit losses, represents their estimated net realizable value. When developing its estimate of expected credit losses on trade and other receivables, the Company considers the available information relevant to assessing the collectability of cash flows, which includes a combination of both internal and external information relating to past events, current conditions, and future forecasts as well as relevant qualitative and quantitative factors that relate to the environment in which the Company operates. Contract assets represent conditional rights to consideration that have been recognized as revenue in advance of billing the customer. Unbilled receivables represent unconditional rights to consideration arising from revenue that have been recognized in advance of billing the customer. Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of prepaid third-party software subscription and license fees, deferred project costs and prepaid taxes. Property and Equipment, Net Property and equipment are recorded at cost, less accumulated depreciation. Maintenance, repairs and minor replacements are charged to expense as incurred. Depreciation on property and equipment, with the exception of leasehold improvements, is recorded using the straight-line method over the estimated useful lives of the assets. Depreciation on leasehold improvements is recorded using the shorter of the lease term or useful life. When property is retired or disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gains or losses are reflected in the Consolidated Statements of Comprehensive Income (Loss) in the period of disposal. Internal-Use Software Costs incurred to develop internal-use software during the application development stage are capitalized, stated at cost, and depreciated using the straight-line method over the estimated useful lives of the assets. Application development stage costs generally include salaries and personnel costs and third-party contractor expenses associated with internal-use software development, configuration and coding. Capitalization of such costs begins when the preliminary project stage is complete and ceases at the point in which the project is substantially complete and is ready for its intended purpose. Capitalized internal-use software is included in property and equipment, net in the Consolidated Balance Sheets. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and noncurrent operating lease liabilities in the Company's Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset over the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company includes any anticipated lease incentives in the determination of lease liability. The Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. The Company gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when determining its incremental borrowing rates. The Company’s lease terms will include options to extend the lease when it is reasonably certain the Company will exercise that option. Leases with a term of 12 months or less are not recorded on the Company's Consolidated Balance Sheet. The Company’s lease agreements do not contain any residual value guarantees. Deferred Costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are capitalized and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. T he Company determined the period of benefit by taking into consideration its customer contracts and expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for contract renewals). The Company also capitalizes amounts earned by employees other than sales representatives who earn incentive payments under compensation plans that are also tied to the value of customer contracts acquired. There were no such amounts capitalized in the years ended December 31, 2022 and 2021. Amortization of deferred costs is included in selling and marketing expense in the Consolidated Statements of Comprehensive Income (Loss). Deferred Implementation Costs The Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), associated with contract arrangements where services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts that are expected to be recoverable. Deferred implementation costs are amortized ratably over the remaining contract term once the revenue recognition criteria for the respective performance obligation has been met and revenue recognition commences. Deferred implementation costs are included in prepaid and other current assets and other assets, noncurrent in the Consolidated Balance Sheets. Amortization of deferred implementation costs is included in cost of subscription and cost of services revenues in the Consolidated Statements of Comprehensive Income (Loss). Deferred Revenue Deferred revenue primarily consists of customer invoicing in advance of revenues being recognized. The Company generally invoices its customers annually in advance for subscription services and maintenance and support services. Deferred revenue anticipated to be recognized during the next twelve-month period is recorded as current deferred revenue and the remaining portion is recorded as noncurrent deferred revenue. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes comparison of future cash flows expected to be generated by the asset or group of assets with the associated assets’ carrying value. If the carrying value of the asset or group of assets exceeds its expected future cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value. Business Combinations, Intangible Assets and Goodwill The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the purchase method of accounting. The allocation of the purchase price in a business combination requires management to make significant estimates in determining the fair value of acquired assets and assumed liabilities, especially with respect to intangible assets. The excess of the purchase price in a business combination over the fair value of these tangible and intangible assets acquired and liabilities assumed is recorded as goodwill. Critical estimates in valuing certain intangible assets include, but are not limited to, projected revenue, discount rate, obsolescence rate, cost of sales, operating expenses and customer attrition rate. The Company estimates fair value primarily utilizing the income and market approaches, including the multi-period excess earnings method for certain intangible assets. Its estimat es are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Consolidated Statement of Comprehensive Income (Loss). Intangible assets that have finite lives are amortized over their useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. During this review, the Company reevaluates the significant assumptions used in determining the original cost and estimated lives of the intangible assets. Although the assumptions may vary from asset to asset, they generally include operating results, changes in the use of the asset, cash flows and other indicators of value. Management then determines whether the remaining useful life continues to be appropriate or whether there has been an impairment of the intangible assets based primarily upon whether expected future undiscounted cash flows are sufficient to support the assets group's recovery. If impairment exists, the Company would adjust the carrying value of the assets to fair value, generally determined by a discounted cash flow analysis. Goodwill represents the excess of the purchase consideration over the net of the acquisition-date fair value of identifiable assets acquired, including identifiable intangible assets, and liabilities assumed in connection with business combinations. Goodwill is not amortized but is assessed for impairment as of November 30 of each fiscal year, or more frequently if events or changes in circumstances indicate the fair value of the Company’s sole reporting unit has been reduced below its carrying value. When conducting the annual goodwill impairment assessment, a two-step process is used. The first step is to perform an optional qualitative evaluation as to whether it is more likely than not that the fair value of the Company’s sole reporting unit is less than its carrying value, using an assessment of relevant events and circumstances. In performing this assessment, the Company is required to make assumptions and judgments including but not limited to an evaluation of macroeconomic conditions as they relate to the business, industry and market trends, as well as the overall future financial performance of the reporting unit and future opportunities in the markets in which it operates. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no additional tests are required to be performed in assessing goodwill for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, the Company performs a second step, consisting of a quantitative assessment of goodwill impairment. This quantitative assessment requires the Company to compare the fair value of its reporting unit with its carrying value. If the carrying amount exceeds the fair value, an impairment charge will be recognized, however, loss cannot exceed the total amount of goodwill allocated to the reporting unit. Based on the results of the qualitative review of goodwill performed as of November 30, 2022, the Company did not identify any indicators of impairment. As such, the quantitative assessment described above was not necessary. Equity Investments Investments in equity securities of privately held companies without readily determinable fair value, where the Company does not exercise significant influence over the investee, are recorded at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee. Adjustments resulting from impairment, fair value, or observable price changes are accounted for in the Consolidated Statements of Comprehensive Income (Loss). Financial Instruments The carrying amount of the Company’s financial instruments, which include cash equivalents, receivables and accounts payable, and equity investments approximates their fair values at December 31, 2022 and 2021. For additional information on the Company’s fair value measurements, see Note 10 to the Consolidated Financial Statements. Convertible Senior Notes Historically, in accounting for the issuance of the Notes, the Company separated each of the Notes into liability and equity components. The carrying amounts of the liability components were calculated by measuring the fair value of similar liabilities that did not have associated convertible features. The carrying amount of the equity components representing the conversion option were determined by deducting the fair value of the liability components from the par value of the respective Notes. These differences represented debt discounts that were amortized to interest expense over the respective terms of the Notes using the effective interest rate method. The equity components were not remeasured as long as they continued to meet the conditions for equity classification. In accounting for the issuance costs related to the Notes, the Company allocated the total amount of issuance costs incurred to the liability and equity components based on their relative values. Issuance costs attributable to the liability components were being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the respective terms of the Notes. The issuance costs attributable to the equity components were netted against the respective equity components in additional paid-in capital. Effective January 1, 2021, the Company early adopted ASU 2020-06, Debt - Debt with Conversion and Other Options ("Subtopic 470-20") and Derivatives and Hedging - Contracts in an Entity's Own Equity ("Subtopic 815-40"); for the impact of adoption of the new standard, refer to "Recently Adopted Accounting Pronouncements" below. Under the new standard, the Company records the principal amount of the Notes as a liability. Issuance costs attributable to the Notes are being amortized on a straight-line basis over the respective terms of the Notes and are presented as a direct deduction from c onvertible debt, net, noncurrent. The 2024 Notes, with a principal amount of $143.8 million, mature on May 15, 2024, unless redeemed or converted in accordance with their terms prior to such date. At December 31, 2022, the Company had $203.6 million of cash and cash equivalents. The Company believes its existing cash and cash equivalents will provide adequate liquidity and capital resources to meet its operational requirements, anticipated capital expenditures and coupon interest payments for the Notes for the next twelve months. Capital markets have tightened recently in response to the macroeconomic environment making new financing more difficult and/or expensive and the Company may not be able to obtain such financing on terms acceptable to it or at all. Research and Development Research and development costs for software sold to customers are generally expensed as incurred. These costs include salaries and personnel costs, including employee benefits, third-party contractor expenses, software development tools, an allocation of facilities and depreciation expenses and other expenses in developing new solutions and upgrading and enhancing existing solutions. Software Development Costs Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins upon the establishment of technological feasibility, which is generally the completion of a working prototype that has been certified as having no critical bugs and is a release candidate. Amortization begins once the software is ready for its intended use, generally based on the pattern in which the economic benefits will be consumed. To date, software development costs incurred between completion of a working prototype and general availability of the related product have not been material. Treasury Stock The Company is authorized to make treasury stock purchases in the open market pursuant to the share repurchase program, which was approved by its Board of Directors on August 28, 2008. The Company accounts for the purchase of treasury stock under the cost method. For additional information on the Company’s stock repurchase program, see Note 12 to the Consolidated Financial Statements. There were no treasury stock repurchases under the program for the years ended December 31, 2022, 2021 and 2020. Revenue Recognition The Company derives its revenues primarily from subscriptions, services, and associated software maintenance and support services. The Company determines revenue recognition through the following steps: • identification of the contract, or contracts, with a customer; • identification of the performance obligations in the customer contract(s); • determination of the transaction price; • allocation of the transaction price to each performance obligation in the customer contract(s); and • recognition of revenue when, or as, the Company satisfies a performance obligation. Subscription revenue Subscription revenue primarily consists of subscription fees that give customers access to one or more of the Company's cloud applications with related customer support. The Company generally recognizes subscription revenue ratably over the contractual term of the arrangement beginning with commencement of service. Subscription revenue related to certain offerings, where fees are based on a number of transactions, are recognized on a usage basi s. The Company's subscription contracts do not provide customers with the right to take possession of the software supporting the service and, as a result, are accounted for as service contracts. The Company's subscription contracts are generally one to five years in length, billed annually in advance, and non-cancelable. Maintenance and support revenue Maintenance and support revenue includes customer support for on-premises licenses and the right to unspecified software updates and enhancements. The Company recognizes revenue from maintenance and support arrangements ratably over the period in which the services are provided. The Company's maintenance and support contracts are generally one year in length, billed annually in advance, and non-cancelable. Services revenue Services revenue primarily consists of fees for configuration services, consulting and training. The Company typically sells its services either on a fixed-fee or time-and-material basis. Services revenue is generally recognized as the services are performed for time and material contracts, or on a proportional performance basis for fixed-price contracts. Training revenue is recognized as the services are rendered. Significant judgments are required in determining whether services contained in the Company's customer subscription contracts are considered distinct, including whether the services are capable of being distinct and whether they are separately identifiable. Services deemed to be distinct are accounted for as a separate performance obligation on a relative standalone selling price basis and revenue is recognized as the services are performed. If services are determined not to be distinct, the services and the subscription are considered to be a single performance obligation and revenue is recognized over the contractual term of the subscription beginning on the date subscription services are made available to the customer. The associated revenue is allocated between subscription and services. Customer contracts with multiple performance obligations A portion of the Company's customer contracts contain multiple performance obligations. Significant judgment is required in determining whether multiple performance obligations contained in a single customer contract are capable of being distinct and are separately identifiable. An obligation determined to be distinct is accounted for as a separate performance obligation and revenue for that separate performance obligation is recognized when, or as, the Company satisfies the performance obligation. If obligations are determined not to be distinct, those obligations are accounted for as a single, combined performance obligation. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. Disaggregation of revenue The Company categorizes revenue from external customers by geographic area based on the location of the customer's headquarters. For additional information regarding the Company's revenue by geography, see Note 19 to the Consolidated Financial Statements. Foreign Currency The Company has certain contracts denominated in foreign currencies and therefore a portion of the Company’s revenue is subject to foreign currency risks. Gains and losses from foreign currency transactions, such as those resulting from the settlement of receivables, are classified in other income, net included in the accompanying Consolidated Statements of Comprehensive Income (Loss). The functional currency of PROS France SAS ("PROS France") is the Euro. The financial statements of this subsidiary are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, historical rates of exchange for equity, and average rates of exchange for the p eriod for revenue and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity (deficit). Noncash Share-Based Compensation The Company's Amended and Restated 2017 Equity Incentive Plan (the "2017 Stock Plan") provides for noncash share-based compensation through the grant of: (i) restricted stock awards; (ii) restricted stock unit awards - time, performance and market-based ("RSUs"); (iii) stock options; (iv) stock appreciation rights ("SARs"); (v) phantom stock; and (vi) performance awards, such as market stock units ("MSUs"). To date, the Company has granted RSUs and MSUs from this plan. The Company issues common stock from its pool of authorized stock upon exercise of stock options, settlement of SARs and MSUs or upon vesting of RSUs. In November 2021, the Company granted inducement awards in an aggregate amount of 332,004 shares in accordance with NYSE Rule 303A.08. These inducement awards were in the form of RSUs granted to certain new employees in connection with the acquisition of EveryMundo. As part of the EveryMundo acquisition in November 2021, the purchase agreement included equity consideration of 273,120 shares of the Company's common stock to be issued to the recipients contingent on their employment with the Company during a two-year period. Based on the underlying agreements, this portion of the consideration was determined to represent post-combination noncash share-based compensation expense from an accounting perspective as opposed to purchase consideration. The following table presents the number of awards outstanding for each award type as of December 31, 2022 and 2021 (in thousands): Year Ended December 31, Award type 2022 2021 Restricted stock units (time-based) 2,235 2,145 Restricted stock units (performance-based) — 140 Market stock units 216 126 EveryMundo Equity consideration 137 273 Restricted stock units. The fair value of the RSUs (time-based and performance-based) is based on the closing price of the Company’s stock on the date of grant and is amortized over the vesting period. RSUs include (i) time-based awards and (ii) performance-based awards in which the number of shares that vest are based upon achievement of certain internal performance metrics set by the Company. Market stock units. MSUs are performance-based awards that vest based upon the Company’s relative shareholder return. The actual number of MSUs that will be eligible to vest is based on the total shareholder return of the Company relative to the total shareholder return of the Russell 2000 Index ("Index") over a 3-year period ending December 31, 2023 and December 31, 2024 ("Performance Period"), respectively. The MSUs will vest on January 31, 2024 and January 31, 2025, respectively. The maximum number of shares issuable upon vesting is 200% of the MSUs initially granted based on the average price of the Company's common stock relative to the Index during the Performance Period. The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The determination of the fair value of the MSUs is affected by the Company’s stock price and a number of assumptions including the expected volatility of the Company’s stock and the Index, its risk-free interest rate and expected dividends. The Company’s expected volatility at the date of grant was based on the historical volatilities of the Company and the Index over the Performance Period. Equity consideration. The fair value of the equity consideration stock awards is based on the closing price of the Company’s stock on the date of grant and is amortized over the vesting period. If factors change and the Company employs different assumptions, noncash share-based compensation expense may differ significantly from what has been recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned noncash share-based compensation expense. Future noncash share-based compensation expense and unearned noncash share-based compensation will increase to the extent that the Company grants additional equity awards to employees. At December 31, 2022, there were an estimated $68.1 million of total unrecognized compensation costs related to noncash share-based compensation arrangements. These costs will be recognized over a weighted average period of 2.5 years. For further discussion of the Company’s noncash share-based compensation plans, see Note 14 to the Consolidated Financial Statements. Income Taxes The Company uses the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. The Company reviews its deferred tax assets for recovery. A valuation allowance is esta blished when the Company believes it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in the Company’s tax provision in the period of change. The Company accounts for uncertain income tax positions recognized in an enterprise’s financial statements in accordance with the income tax topic of the ASC issued by the FASB. This interpretation requires companies to use a prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in its tax returns. This guidance provides clarification on recognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. The Company recognizes accrued interest and penalties related to income taxes, if any, as a component of income tax expense. For additional information regarding the Company’s income taxes, see Note 15 to the Consolidated Financial Statements. Segment Reporting The Company reports as one operating segment with the Chief Executive Officer ("CEO") acting as the Company’s chief operating decision maker. The Company’s CEO reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has a single reporting unit, and there are no segment managers who are held accountable for operations, operating results or components below the consolidated unit level. Earnings Per Share The Company computes basic earnings (loss) per share by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding. Diluted earnings (loss) per share is computed by giving effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible notes using the if-converted method. Dilutive potential common shares consist of shares issuable upon the exercise of stock options, shares of unvested restricted stock units, market stock units and equity consideration, and settlement of stock appreciation rights, if any. When the Company incurs a net loss, the effect of the Company's outstanding stock options, stock appreciation rights,

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Business Combinations EveryMundo On November 30, 2021, the Company acquired EveryMundo LLC ("EveryMundo"), a privately held company based in Miami, Florida, for a cash consideration, net of cash acquired, of approximately $79.5 million and an equity consideration of approximately $10.0 million. Since the equity consideration is contingent on certain employees' continued employment with the Company for a two-year period, it was determined, based on accounting guidance, the related amounts should be treated as post-combination compensation and accordingly are not included as part of the purchase price allocation. EveryMundo is a digital offer marketing pioneer that enables brands to broaden their digital reach and deepen customer engagement, providing greater control over direct and indirect channels they participate in to help create superior brand experiences and foster brand loyalty over time. Since the acquisition date and for the year ended December 31, 2021, the Company has included $1.1 million of revenue and $1.4 million of net loss related to EveryMundo in its Consolidated Statements of Comprehensive Income (Loss). During the years ended December 31, 2022 and 2021, the Company incurred acquisition-related costs of zero and $2.4 million, respectively, consisting primarily of advisory, legal, accounting and other professional fees, and integration costs.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Measurements The Company adopted fair value measurements guidance for financial and nonfinancial assets and liabilities. The guidance defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. The guidance defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. The guidance establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 : Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 : Quoted prices for similar assets or liabilities in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 : Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A portion of the Company’s existing cash and cash equivalents are invested in short-term interest bearing obligations with original maturities less than 90 days, principally various types of money market funds. The Company does not enter into investments for trading or speculative purposes. At December 31, 2022 and 2021, the Company had approximately $168.1 million and $203.3 million invested in treasury money market funds. The fair value of the treasury money market funds is determined based on quoted market prices, which represents level 1 in the fair value hierarchy as defined by Accounting Standard Codification ("ASC") 820, " Fair Value Measurement and Disclosure ." The fair value of the Company's Notes is classified in the level 2 hierarchy. See Note 16 for further detail regarding the Notes. As of December 31, 2022 and 2021, the Company had $7.1 million and $5.5 million, respectively, of equity securities in privately held companies and a venture fund, which are included in other assets, noncurrent in the Consolidated Balance Sheet. These investments are accounted for at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee. The Company estimates the fair value of its equity investments by considering available information such as pricing in recent rounds of financing and any other readily available market data, which represents level 3 in the fair value hierarchy. An impairment charge to current earnings is recorded when the cost of the investment exceeds its fair value and if a qualitative assessment indicated that the investment is impaired.

Noncash Share-based Compensation [Abstract]
Noncash Share-based Compensation	Noncash Share-Based Compensation Employee Noncash Share-based Compensation Plans 2017 Stock Plan. The Company’s 2017 Stock Plan provides for the issuance of awards to employees, officers, directors and certain other individuals providing services to the Company who are eligible to receive awards. In May 2021, the Company's stockholders approved an amendment to the 2017 Stock Plan increasing the aggregate amount of shares available for issuance to 7,650,000. The Company may provide these incentives through the grant of: (i) restricted stock awards; (ii) RSUs (time, performance and market-based); (iii) stock options; (iv) SARs; (v) phantom stock; and (vi) performance awards, such as MSUs. As of December 31, 2022, there were no outstanding equity awards under any of the previous Company stock plans. As of December 31, 2022, the Company had outstanding equity awards to acquire 2,204,569 shares of its common stock held by the Company’s employees, directors and consultants under the 2017 Stock Plan (assuming MSU performance at 100% of the MSUs initially granted), and inclusive of 1,988,883 RSUs and 215,686 MSUs. As of December 31, 2022, 2,983,140 shares remain available for grant under the 2017 Stock Plan. As of December 31, 2022, there were no options, SARs, restricted stock awards or phantom stock issued under the 2017 Stock Plan. Inducement awards. In November 2021, the Company granted inducement awards in an aggregate amount of 332,004 shares in accordance with NYSE Rule 303A.08. These inducement awards were in the form of RSUs granted to certain new employees in connection with the acquisition of EveryMundo. As of December 31, 2022, the Company had 245,816 outstanding equity inducement awards (the inducement awards, together with the 2017 Stock Plan are referred to as the "Stock Plans"). Equity consideration. As part of the EveryMundo acquisition in November 2021, the purchase agreement included equity consideration of 273,120 shares of the Company's common stock to be issued to the recipients contingent on their employment with the Company during a two-year period. Based on the underlying agreements, this portion of the consideration was determined to represent post-combination noncash share-based compensation expense from an accounting perspective as opposed to purchase consideration. The grant date fair value of the equity consideration stock awards is $36.32 and they vest in equal annual installments over a two-year period from the grant date . As of December 31, 2022, the Company had 136,560 outstanding equity consideration shares. Noncash share-based compensation expense for all noncash share-based payment awards granted is determined based on the grant date fair value of the award. The Company recognizes compensation expense, net of estimated forfeitures, which represents noncash share-based awards expected to vest on a straight-line basis over the requisite service period of the award, which is generally the vesting term. Noncash share-based awards typically vest over four years. The Company estimates forfeiture rates based on its historical experience for grant years where the majority of the vesting terms have been satisfied. Changes in estimated forfeiture rates are recognized through a cumulative catch-up adjustment in the period of change and thus impact the amount of noncash share-based compensation expense to be recognized in future periods. Noncash share-based compensation expense is allocated to expense categories on the Consolidated Statements of Comprehensive Income (Loss). The following table summarizes noncash share-based compensation expense, net of amounts capitalized, for the years ended December 31, 2022, 2021 and 2020 (in thousands). For the Year Ended December 31, 2022 2021 2020 Share-based compensation: Cost of revenue $ 3,898 $ 3,679 $ 2,132 Operating expenses: Selling and marketing 12,360 10,407 6,536 Research and development 12,496 8,288 6,061 General and administrative 13,960 12,701 9,670 Total included in operating expenses 38,816 31,396 22,267 Total share-based compensation expense $ 42,714 $ 35,075 $ 24,399 At December 31, 2022, there were an estimated $68.1 million of total unrecognized compensation costs related to noncash share-based compensation arrangements. These costs will be recognized over a weighted average period of 2.5 years. RSUs (time-based) The Company has granted time-based RSUs under the Stock Plans. Time-based RSUs granted to employees, directors and consultants have historically vested in equal annual installments over a one to four-year period from the grant date. RSUs granted in 2022 vest 25% after one year and in equal quarterly installments for the remaining term of the award which is typically three additional years. The following table summarizes the Company's unvested time-based RSUs as of December 31, 2022, and changes during the year then ended (number of shares in thousands): Number of Weighted Weighted Unvested at December 31, 2021 2,145 $ 43.57 Granted 1,416 30.03 Vested (869) 40.95 Forfeited (457) 39.49 Unvested at December 31, 2022 2,235 $ 36.39 2.60 The weighted average grant-date fair value of the time-based RSUs granted during the years ended December 31, 2022, 2021 and 2020 was $30.03, $43.28 and $52.62, respectively. The total fair value as of the respective vesting date of time-based RSUs vested during the years ended December 31, 2022, 2021 and 2020 was $24.6 million , $32.9 million and $46.7 million , respectively. RSUs (performance-based) During 2019 and 2020, the Company granted performance-based RSUs ("PRSUs") under the 2017 Stock Plan to certain executive employees. The actual number of PRSUs that were eligible to vest pursuant to these awards, up to a maximum of 200% of the PRSUs initially granted, was based upon achievement of certain internal performance metrics, as defined by each award's plan documents or individual award agreements. The shares earned from the 2019 PRSUs vested on January 15, 2022. No shares were earned from the 2020 PRSUs. The following table summarizes the Company's unvested PRSUs as of December 31, 2022, and changes during the year then ended (number of shares in thousands): Number of Weighted Weighted Unvested at December 31, 2021 140 $ 42.93 Granted — — Vested (75) 33.05 Forfeited (65) 54.23 Unvested at December 31, 2022 — $ — 0 The weighted average grant-date fair value of the performance-based RSUs granted during the year ended December 31, 2020 was $54.23. The total fair value as of the respective vesting date of performance-based RSUs vested during the year ended December 31, 2022 was $2.1 million. MSUs I n 2021 and 2022, the Company granted MSUs to certain executive employees under the Stock Plans. The MSUs are performance-based awards that vest based upon the Company’s relative shareholder return. The actual number of MSUs that will be eligible to vest is based on the total shareholder return of the Company relative to the total shareholder return of the Index over the 3-year Performance Period. The 2021 MSUs will vest on January 31, 2024 and the 2022 MSUs will vest on January 31, 2025. The MSUs maximum number of shares issuable upon vesting is 200% of the MSUs initially granted. The Company did not grant any MSUs in 2020. The following table summarizes the Company's MSUs activity for the year ended December 31, 2022 (number of shares in thousands): Number of Weighted Weighted Unvested at December 31, 2021 126 $ 56.05 Granted 117 37.65 Vested — — Forfeited (27) 56.05 Expired — — Unvested at December 31, 2022 216 $ 43.34 1.63 The total fair value as of the respective vesting date of the MSUs vested during the years ended December 31, 2022, 2021 and 2020 was zero , $10.7 million and $12.7 million , respectively. The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The determination of the fair value of the MSUs is affected by the Company's stock price and a number of assumptions including the expected volatilities of the Company's stock and the Index, its risk-free interest rate and expected dividends. The Company's expected volatility at the date of grant was based on the historical volatilities of the Company and the Index over the Performance Period. The Company did not estimate a forfeiture rate for the MSUs due to the limited size, the vesting period and nature of the grantee population and the lack of history of granting this type of award. Significant assumptions used in the Monte Carlo simulation model for MSUs granted during the year ended December 31, 2022 and 2021 are as follows: For the Year Ended December 31, 2022 2021 Volatility 54.50% 53.29% Risk-free interest rate 1.20% 0.22% Expected award life in years 2.97 2.97 Dividend yield —% —% Employee Stock Purchase Plan The Company's Employee Stock Purchase Plan ("ESPP") provides for eligible employees to purchase shares on an after-tax basis in an amount between 1% and 10% of their annual pay: (i) on June 30 of each year at a 15% discount of the fair market value of the Company's common stock on January 1 or June 30, whichever is lower, and (ii) on December 31 of each year at a 15% discount of the fair market value of the Company's common stock on July 1 or December 31, whichever is lower. An employee may not purchase more than $5,000 in either of the six-month measurement periods described above or more than $10,000 annually. In May 2021, the Company's stockholders approved an amendment to the ESPP Plan increasing the aggregate amount of shares available for issuance under the ESPP to 1,000,000. During the year ended December 31, 2022, the Company issued 106,586 shares under the ESPP. As of December 31, 2022, 387,125 shares remain authorized and available for issuance under the ESPP. As of December 31, 2022, the Company held approximately $1.1 million on behalf of employees for future purchases under the ESPP, and this amount was recorded in accrued liabilities in the Company's Consolidated Balance Sheet.

During the year ended December 31, 2022, the Company's effective tax rate was impacted primarily by changes in valuation allowance. The tax effects of temporary differences and other tax attributes that give rise to significant portions of the deferred tax assets and liabilities as of December 31, 2022 and 2021 are as follows (in thousands): Year Ended December 31, 2022 2021 Noncurrent deferred taxes: Property and equipment $ (812) $ (694) Noncash share-based compensation 3,611 3,235 Disallowed interest expense 2,664 9,290 Capitalized software (66) (1,534) Amortization 2,074 1,364 Operating lease right-of-use assets (8,238) (6,374) Operating lease liabilities 12,305 10,914 R&E tax credit carryforwards 16,862 14,886 Capitalized research and development expenses 18,089 — Deferred revenue 1,823 1,879 Federal Net Operating Losses ("NOLs") 92,960 92,960 State NOLs 3,589 3,165 State Credits 4,157 4,157 Foreign NOLs 15,381 11,759 Foreign tax credit carryforward 2,057 2,168 Other (671) (223) Total noncurrent deferred tax assets 165,785 146,952 Less: Valuation allowance (165,671) (146,832) Total net deferred tax asset $ 114 $ 120 The net deferred tax asset is classified as other assets, noncurrent in the accompanying Consolidated Balance Sheets. The Company continues to record a valuation allowance against its U.S. Federal, U.S. State, and France net deferred tax balances. This valuation allowance is evaluated periodically and will be reversed partially or in whole if business results and the economic environment have sufficiently improved to support realization of some or all of the Company's deferred tax assets. In performing the analysis throughout 2022, the Company determined that there was no sufficient positive evidence to outweigh the current and historic negative evidence to determine that it was more likely than not that the deferred assets would not be realized. Therefore, the Company continues to have a valuation allowance against net deferred tax assets as of December 31, 2022 and 2021. The U.S. federal net operating losses, R&E tax credit and U.S. foreign tax credit carryforward amount available to be used in future periods, taking into account the Section 382 annual limitation and current year losses, is approximately $443.2 million, $21.0 million and $2.1 million, respectively. The Company’s net operating losses will begin to expire in 2024, R&E credits will begin to expire in 2031, and foreign tax credits began to expire in 2022. The U .S. net operating losses generated after January 1, 2018 have no expiration. Also included in foreign net operating losses are $55.0 million of French carryforwards which have no expiration. The Company has federal and state net operating loss carryforwards related to current and prior year operations and acquisitions. Internal Revenue Code Section 382 ("Section 382") places certain limitations on the annual amount of U.S. net operating loss carryforwards that can be utilized when a change of ownership occurs. The Company believes the past acquisitions were changes in ownership pursuant to Section 382, subjecting federal acquired net operating losses to limitations. According to French tax law, the net operating loss carryforwards are not subject to ownership change limitations. Undistributed earnings of the Company’s foreign subsidiaries are considered permanently reinvested and, accordingly, no provision for U.S. federal or state income taxes or non-U.S. withholding taxes has been provided thereon. The cumulative amount of positive undistributed earnings of the Company’s non-U.S. subsidiaries, if any, was minimal for the years ended December 31, 2022 and 2021. The Company is presently investing in international operations located in Europe, North America, the United Arab Emirates, Australia, Hong Kong and Singapore. The Company is funding the working capital needs of its foreign operations through its U.S. operations. In the future, the Company plans to utilize its foreign undistributed earnings, as well as continued funding from its U.S. operations, to support its continued foreign investment. For the year ended December 31, 2022, the Company had no balance in its reserve for unrecognized tax benefits. The balances for net unrecognized tax benefits for the years ended December 31, 2021 and 2020 were immaterial. The Company recorded immaterial amounts for interest and penalties to tax expense as of December 31, 2021 and 2020, respectively. During 2021, the Company determined that the statute of limitations concluded for specific positions and removed these positions from the uncertain tax positions. The Company continually monitors tax positions and will evaluate if any new positions need to be added during the next twelve months. The following table sets forth the changes to the Company's unrecognized tax benefit for the year ended December 31, 2022, 2021 and 2020 (in thousands): Year Ended December 31, 2022 2021 2020 Beginning balance $ — $ 14 $ 14 Changes based on tax positions related to prior year — — — Changes due to settlement — (14) — Ending balance $ — $ — $ 14 The table above has been updated to reflect gross tax liability, exclusive of interest and penalties and other offsetting amounts.

Debt Instrument [Line Items]
Long-term Debt [Text Block]	Convertible Senior Notes The Company issued $143.8 million principal amount of the 2024 Notes in May 2019 and $150.0 million principal amount of the 2027 Notes in September 2020. The interest rate for the 2024 Notes is fixed at 1% per annum and interest is payable semi-annually in arrears on May 15 and November 15 of each year, commencing on November 15, 2019. The interest rate for the 2027 Notes is fixed at 2.25% per annum and int erest is payable semiannually in arrears in cash on March 15 and September 15 of each year, beginning on March 15, 2021. The effective interest rate related to the amortization of the liability component of the 2024 Notes and the 2027 Notes prior to the adoption of ASU 2020-06 was 6.6% and 8.5%, respectively . The 2024 Notes mature on May 15, 2024 and the 2027 Notes mature on September 15, 2027, unless redeemed or converted in accordance with their terms prior to such date. Each $1,000 of principal of the 2024 Notes will initially be convertible into 15.1394 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $66.05 per share. Each $1,000 of principal of the 2027 Notes will initially be convertible into 23.9137 shares of the Company’s common stock, which is equivalent to an initial conversion price of approximately $41.82 per share. The initial conversion price for each of the Notes is subject to adjustment upon the occurrence of certain specified events. The Notes are each general unsecured obligations and rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated, are effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and are structurally subordinated to all indebtedness and other liabilities of the Company's subsidiaries (including trade payables but excluding intercompany obligations owed to the Company or its subsidiaries). On or after February 15, 2024 and June 15, 2027, respectively, to the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2024 and 2027 Notes, respectively, regardless of the contingent conversion conditions described herein. Upon conversion, the Company will pay or deliver cash, shares of its common stock or a combination of cash and shares of its common stock, at its election, as described in the indenture governing the 2024 and 2027 Notes. Holders may convert their 2024 and 2027 Notes at their option at any time prior to the close of business on the business day immediately preceding February 15, 2024 and June 15, 2027, respectively, only under the following circumstances: • during the five consecutive business day period immediately following any five consecutive trading day period (the "Measurement Period") in which the trading price per 2024 and 2027 Note, respectively, for each day of that Measurement Period was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate on each such day; • during any calendar quarter commencing after the calendar quarter ending on June 30, 2019 and December 31, 2020, respectively, if the last reported sale price of the common stock for 20 or more trading days (whether or not consecutive) in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; or • upon the occurrence of specified corporate events. If a fundamental change (as defined in the relevant indenture governing the applicable series of Notes) occurs prior to the maturity date, holders of each of the Notes may require the Company to repurchase all or a portion of their notes for cash at a repurchase price equal to 100% of the principal amount at maturity of the Notes, plus any accrued and unpaid interest to, but excluding, the repurchase date. In accordance with accounting guidance on embedded conversion features at the time of the Notes issuance, the Company valued and bifurcated the conversion options associated with each of the Notes from the respective host debt instrument, which is referred to as debt discount, and recorded the conversion option of each of the Notes in stockholders’ equity at the time of the issuance of the Notes. Effective January 1, 2021, the Company early adopted ASU 2020-06, Debt - Debt with Conversion and Other Options and Derivatives and Hedging - Contracts in an Entity's Own Equity. Upon adoption of the new standard, the Company removed t he debt discount and adjusted the debt issuance cost which was previously allocated between the liability and the equity component, resulting in an increase of $68.8 million to convertible debt, net. In addition, the Company recorded a reduction to additional paid-in capital of $80.1 million related to the equity conversion component of the outstanding convertible notes which was previously separated and recorded in equity. The net cumulative impact of the adoption of the standard was recorded as a decrease to accumulated deficit. As of December 31, 2022, the 2024 and 2027 Notes are not yet convertible, and their remaining life is approximately 16 months and 56 months, respectively. As of December 31, 2022 and 2021, the fair value of the principal amount of the Notes was $263.7 million and $299.4 million, respectively. The estimated fair value was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, including the Company's stock price and interest rates, which represents level 2 in the fair value hierarchy. The Notes consist of the following (in thousands): December 31, 2022 December 31, 2021 Liability component: Principal $ 293,750 $ 293,750 Less: debt issuance cost, net of amortization (3,971) (5,463) Net carrying amount $ 289,779 $ 288,287 The following table sets forth total interest expense recognized related to the Notes (in thousands): Year Ended December 31, 2022 2021 2020 Coupon $ 4,813 $ 4,813 $ 2,422 Amortization of debt issuance costs 1,491 1,491 733 Amortization of debt discount — — 7,970 Total $ 6,304 $ 6,304 $ 11,125 Capped Call Transactions In May 2019 and in September 2020, in connection with the offering of the 2024 and 2027 Notes, respectively, the Company entered into privately negotiated capped call transactions (collectively, the "Capped Call") with certain option counterparties. The Capped Call transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock initially underlying the Notes, at a strike price that corresponds to the initial conversion price of the Notes, also subject to adjustment, and are exercisable upon conversion of the Notes. The Capped Call transactions are intended to reduce potential dilution to the Company’s common stock and/or offset any cash payments the Company will be required to make in excess of the principal amounts upon any conversion of Notes, and to effectively increase the overall conversion price of the 2024 Notes from $66.05 to $101.62 per share and for the 2027 Notes from $41.82 to $78.90 per share. As the Capped Call transactions meet certain accounting criteria, they are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of the Capped Call was $16.4 million and $25.3 million for the 2024 and 2027 Notes, respectively, and was recorded as part of additional paid-in capital.

The Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. The Company is not currently involved in any outstanding litigation that it believes, individually or in the aggregate, will have a material adverse effect on its business, financial condition, results of operations or cash flows. Purchase Commitments The purchase commitments consist of agreements to purchase goods and services entered into the ordinary course of business, mainly related to infrastructure platforms, business technology software and support, and other services. The following table summarizes the non-cancelable unconditional purchase commitments for each of the next five years and thereafter as of December 31, 2022 (in thousands): Year Ending December 31, Amount 2023 $ 34,541 2024 40,385 2025 44,131 2026 47,416 2027 — Thereafter — Total $ 166,473 Indemnification The Company’s software agreements generally include certain provisions for indemnifying customers against liabilities if the Company’s software solutions infringe a third party’s intellectual property rights.

Segment Reporting Disclosure [Text Block]	Segment and Geographic Information The Company operates as one segment with a single reporting unit. Operating segments are the components of an enterprise where separate financial information is evaluated regularly by the chief operating decision-maker, who is the Company's Chief Executive Officer, in deciding how to allocate resources and assessing financial performance. The Company's chief operating decision-maker allocates resources and assesses performance based upon discrete financial information at the consolidated level. Revenue by Geography The Company presents financial information on a consolidated basis and does not assess the profitability of its geographic regions. Accordingly, the Company does not attempt to comprehensively assign or allocate costs to these regions and does not produce reports for, or measure the performance of, its geographic regions based on any asset-based metrics. International revenue for the years ended December 31, 2022, 2021 and 2020, amounted to approximately $177.8 million, $162.5 million and $170.1 million, respectively, representing 64%, 65% and 67%, respectively, of annual revenue.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Principles of Consolidation and Basis of PresentationThese Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP"). Certain prior year amounts have been reclassified for consistency with the current year presentation. Such reclassifications impacted the classification of general and administrative expenses and research and development expenses. These insignificant reclassifications had no effect on the reported results of operations, cash flows, or financial position.
Accounting Standards Update and Change in Accounting Principle	Changes in Accounting Policies The Company has consistently applied the accounting policies described in this Note 2 to all periods presented in these Consolidated Financial Statements, except for the Company's adoption of certain accounting standards described in more detail under " Recently adopted accounting pronouncements " in this Note 2 below.
Dollar amounts	Dollar Amounts The dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars, except per share amounts, or as noted within the context of each footnote disclosure.
Use of estimates	Use of Estimates The preparation of these Consolidated Financial Statements in conformity with GAAP requires the Company to make certain estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses during the reporting period. The complexity and judgment required in the Company's estimation process, as well as issues related to the assumptions, risks and uncertainties inherent in determining the nature and timing of satisfaction of performance obligations and determining the standalone selling price of performance obligations, affect the amounts of revenue, expenses, unbilled receivables and deferred revenue. Estimates are also used for, but not limited to, receivables, allowance for credit losses, the determination of the period of benefit for deferred commissions, operating lease right-of-use assets and operating lease liabilities, useful lives of assets, depreciation and amortization, fair value of assets acquired and liabilities assumed for business combinations, income taxes and deferred tax asset valuation, valuation of stock awards, other current liabilities and accrued liabilities. Numerous internal and external factors can affect estimates. Actual results could differ from those estimates and such differences could be material to the Company's consolidated financial position and results of operations.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase, or the ability to be settled in cash within a period of three months, to be cash equivalents, except for commercial paper which is classified as short-term investments, if any. The Company has a cash management program that provides for the investment of excess cash balances, primarily in short-term money market instruments.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]	Trade and Other Receivables Trade and other receivables are primarily comprised of trade receivables, net of allowance for credit losses, contract assets and unbilled receivables. The Company records trade accounts receivable for its unconditional rights to consideration arising from the Company's performance under contracts with customers. The Company's standard billing terms are generally within thirty to sixty days from the date of the invoice. The carrying value of such receivables, net of the allowance for credit losses, represents their estimated net realizable value. When developing its estimate of expected credit losses on trade and other receivables, the Company considers the available information relevant to assessing the collectability of cash flows, which includes a combination of both internal and external information relating to past events, current conditions, and future forecasts as well as relevant qualitative and quantitative factors that relate to the environment in which the Company operates. Contract assets represent conditional rights to consideration that have been recognized as revenue in advance of billing the customer. Unbilled receivables represent unconditional rights to consideration arising from revenue that have been recognized in advance of billing the customer.
Prepaid Expenses and Other Assets [Policy Text Block]	Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of prepaid third-party software subscription and license fees, deferred project costs and prepaid taxes.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment, Net Property and equipment are recorded at cost, less accumulated depreciation. Maintenance, repairs and minor replacements are charged to expense as incurred. Depreciation on property and equipment, with the exception of leasehold improvements, is recorded using the straight-line method over the estimated useful lives of the assets. Depreciation on leasehold improvements is recorded using the shorter of the lease term or useful life. When property is retired or disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gains or losses are reflected in the Consolidated Statements of Comprehensive Income (Loss) in the period of disposal.
Internal-use software	Internal-Use Software Costs incurred to develop internal-use software during the application development stage are capitalized, stated at cost, and depreciated using the straight-line method over the estimated useful lives of the assets. Application development stage costs generally include salaries and personnel costs and third-party contractor expenses associated with internal-use software development, configuration and coding. Capitalization of such costs begins when the preliminary project stage is complete and ceases at the point in which the project is substantially complete and is ready for its intended purpose. Capitalized internal-use software is included in property and equipment, net in the Consolidated Balance Sheets.
Lessee, Leases [Policy Text Block]	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current operating lease liabilities and noncurrent operating lease liabilities in the Company's Consolidated Balance Sheet. ROU assets represent the Company’s right to use an underlying asset over the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company includes any anticipated lease incentives in the determination of lease liability. The Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. The Company gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when determining its incremental borrowing rates. The Company’s lease terms will include options to extend the lease when it is reasonably certain the Company will exercise that option. Leases with a term of 12 months or less are not recorded on the Company's Consolidated Balance Sheet. The Company’s lease agreements do not contain any residual value guarantees.
Revenue Recognition, Customer Acquisitions [Policy Text Block]	Deferred Costs Sales commissions earned by the Company's sales representatives are considered incremental and recoverable costs of obtaining a customer contract. Sales commissions are capitalized and amortized on a straight-line basis over the period of benefit, which the Company has determined to be five to eight years. T he Company determined the period of benefit by taking into consideration its customer contracts and expected renewals of those customer contracts (as the Company currently does not pay an incremental sales commission for contract renewals). The Company also capitalizes amounts earned by employees other than sales representatives who earn incentive payments under compensation plans that are also tied to the value of customer contracts acquired. There were no such amounts capitalized in the years ended December 31, 2022 and 2021. Amortization of deferred costs is included in selling and marketing expense in the Consolidated Statements of Comprehensive Income (Loss).
Deferred Charges, Policy [Policy Text Block]	Deferred Implementation Costs The Company capitalizes certain contract fulfillment costs, including personnel and other costs (such as hosting, employee salaries, benefits and payroll taxes), associated with contract arrangements where services are not distinct from other undelivered performance obligations in its customer contracts. The Company analyzes implementation costs and capitalizes those costs directly related to customer contracts that are expected to be recoverable. Deferred implementation costs are amortized ratably over the remaining contract term once the revenue recognition criteria for the respective performance obligation has been met and revenue recognition commences. Deferred implementation costs are included in prepaid and other current assets and other assets, noncurrent in the Consolidated Balance Sheets. Amortization of deferred implementation costs is included in cost of subscription and cost of services revenues in the Consolidated Statements of Comprehensive Income (Loss).
Revenue Recognition, Deferred Revenue [Policy Text Block]	Deferred Revenue    Deferred revenue primarily consists of customer invoicing in advance of revenues being recognized. The Company generally invoices its customers annually in advance for subscription services and maintenance and support services. Deferred revenue anticipated to be recognized during the next twelve-month period is recorded as current deferred revenue and the remaining portion is recorded as noncurrent deferred revenue.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates that the carrying amount of an asset or group of assets may not be recoverable. The impairment review includes comparison of future cash flows expected to be generated by the asset or group of assets with the associated assets’ carrying value. If the carrying value of the asset or group of assets exceeds its expected future cash flows (undiscounted and without interest charges), an impairment loss is recognized to the extent that the carrying amount of the asset exceeds its fair value.
Business Combinations, Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Business Combinations, Intangible Assets and Goodwill The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the purchase method of accounting. The allocation of the purchase price in a business combination requires management to make significant estimates in determining the fair value of acquired assets and assumed liabilities, especially with respect to intangible assets. The excess of the purchase price in a business combination over the fair value of these tangible and intangible assets acquired and liabilities assumed is recorded as goodwill. Critical estimates in valuing certain intangible assets include, but are not limited to, projected revenue, discount rate, obsolescence rate, cost of sales, operating expenses and customer attrition rate. The Company estimates fair value primarily utilizing the income and market approaches, including the multi-period excess earnings method for certain intangible assets. Its estimat es are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Consolidated Statement of Comprehensive Income (Loss). Intangible assets that have finite lives are amortized over their useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. During this review, the Company reevaluates the significant assumptions used in determining the original cost and estimated lives of the intangible assets. Although the assumptions may vary from asset to asset, they generally include operating results, changes in the use of the asset, cash flows and other indicators of value. Management then determines whether the remaining useful life continues to be appropriate or whether there has been an impairment of the intangible assets based primarily upon whether expected future undiscounted cash flows are sufficient to support the assets group's recovery. If impairment exists, the Company would adjust the carrying value of the assets to fair value, generally determined by a discounted cash flow analysis. Goodwill represents the excess of the purchase consideration over the net of the acquisition-date fair value of identifiable assets acquired, including identifiable intangible assets, and liabilities assumed in connection with business combinations. Goodwill is not amortized but is assessed for impairment as of November 30 of each fiscal year, or more frequently if events or changes in circumstances indicate the fair value of the Company’s sole reporting unit has been reduced below its carrying value. When conducting the annual goodwill impairment assessment, a two-step process is used. The first step is to perform an optional qualitative evaluation as to whether it is more likely than not that the fair value of the Company’s sole reporting unit is less than its carrying value, using an assessment of relevant events and circumstances. In performing this assessment, the Company is required to make assumptions and judgments including but not limited to an evaluation of macroeconomic conditions as they relate to the business, industry and market trends, as well as the overall future financial performance of the reporting unit and future opportunities in the markets in which it operates. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no additional tests are required to be performed in assessing goodwill for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, the Company performs a second step, consisting of a quantitative assessment of goodwill impairment. This quantitative assessment requires the Company to compare the fair value of its reporting unit with its carrying value. If the carrying amount exceeds the fair value, an impairment charge will be recognized, however, loss cannot exceed the total amount of goodwill allocated to the reporting unit. Based on the results of the qualitative review of goodwill performed as of November 30, 2022, the Company did not identify any indicators of impairment. As such, the quantitative assessment described above was not necessary.
Investment, Policy	Equity Investments Investments in equity securities of privately held companies without readily determinable fair value, where the Company does not exercise significant influence over the investee, are recorded at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee. Adjustments resulting from impairment, fair value, or observable price changes are accounted for in the Consolidated Statements of Comprehensive Income (Loss).
Fair Value of Financial Instruments, Policy [Policy Text Block]	Financial Instruments The carrying amount of the Company’s financial instruments, which include cash equivalents, receivables and accounts payable, and equity investments approximates their fair values at December 31, 2022 and 2021. For additional information on the Company’s fair value measurements, see Note 10 to the Consolidated Financial Statements.
Debt, Policy [Policy Text Block]	Convertible Senior NotesHistorically, in accounting for the issuance of the Notes, the Company separated each of the Notes into liability and equity components. The carrying amounts of the liability components were calculated by measuring the fair value of similar liabilities that did not have associated convertible features. The carrying amount of the equity components representing the conversion option were determined by deducting the fair value of the liability components from the par value of the respective Notes. These differences represented debt discounts that were amortized to interest expense over the respective terms of the Notes using the effective interest rate method. The equity components were not remeasured as long as they continued to meet the conditions for equity classification. In accounting for the issuance costs related to the Notes, the Company allocated the total amount of issuance costs incurred to the liability and equity components based on their relative values. Issuance costs attributable to the liability components were being amortized on a straight-line basis, which approximates the effective interest rate method, to interest expense over the respective terms of the Notes. The issuance costs attributable to the equity components were netted against the respective equity components in additional paid-in capital. Effective January 1, 2021, the Company early adopted ASU 2020-06, Debt - Debt with Conversion and Other Options ("Subtopic 470-20") and Derivatives and Hedging - Contracts in an Entity's Own Equity ("Subtopic 815-40"); for the impact of adoption of the new standard, refer to "Recently Adopted Accounting Pronouncements" below. Under the new standard, the Company records the principal amount of the Notes as a liability. Issuance costs attributable to the Notes are being amortized on a straight-line basis over the respective terms of the Notes and are presented as a direct deduction from c onvertible debt, net, noncurrent. The 2024 Notes, with a principal amount of $143.8 million, mature on May 15, 2024, unless redeemed or converted in accordance with their terms prior to such date. At December 31, 2022, the Company had $203.6 million of cash and cash equivalents. The Company believes its existing cash and cash equivalents will provide adequate liquidity and capital resources to meet its operational requirements, anticipated capital expenditures and coupon interest payments for the Notes for the next twelve months. Capital markets have tightened recently in response to the macroeconomic environment making new financing more difficult and/or expensive and the Company may not be able to obtain such financing on terms acceptable to it or at all.
Research, Development, and Computer Software, Policy [Policy Text Block]	Research and Development Research and development costs for software sold to customers are generally expensed as incurred. These costs include salaries and personnel costs, including employee benefits, third-party contractor expenses, software development tools, an allocation of facilities and depreciation expenses and other expenses in developing new solutions and upgrading and enhancing existing solutions. Software Development Costs Capitalization of software development costs for software to be sold, leased, or otherwise marketed begins upon the establishment of technological feasibility, which is generally the completion of a working prototype that has been certified as having no critical bugs and is a release candidate. Amortization begins once the software is ready for its intended use, generally based on the pattern in which the economic benefits will be consumed. To date, software development costs incurred between completion of a working prototype and general availability of the related product have not been material.
Treasury Stock [Text Block]	Treasury Stock The Company is authorized to make treasury stock purchases in the open market pursuant to the share repurchase program, which was approved by its Board of Directors on August 28, 2008. The Company accounts for the purchase of treasury stock under the cost method. For additional information on the Company’s stock repurchase program, see Note 12 to the Consolidated Financial Statements. There were no treasury stock repurchases under the program for the years ended December 31, 2022, 2021 and 2020.
Revenue recognition	Revenue Recognition The Company derives its revenues primarily from subscriptions, services, and associated software maintenance and support services. The Company determines revenue recognition through the following steps: • identification of the contract, or contracts, with a customer; • identification of the performance obligations in the customer contract(s); • determination of the transaction price; • allocation of the transaction price to each performance obligation in the customer contract(s); and • recognition of revenue when, or as, the Company satisfies a performance obligation. Subscription revenue Subscription revenue primarily consists of subscription fees that give customers access to one or more of the Company's cloud applications with related customer support. The Company generally recognizes subscription revenue ratably over the contractual term of the arrangement beginning with commencement of service. Subscription revenue related to certain offerings, where fees are based on a number of transactions, are recognized on a usage basi s. The Company's subscription contracts do not provide customers with the right to take possession of the software supporting the service and, as a result, are accounted for as service contracts. The Company's subscription contracts are generally one to five years in length, billed annually in advance, and non-cancelable. Maintenance and support revenue Maintenance and support revenue includes customer support for on-premises licenses and the right to unspecified software updates and enhancements. The Company recognizes revenue from maintenance and support arrangements ratably over the period in which the services are provided. The Company's maintenance and support contracts are generally one year in length, billed annually in advance, and non-cancelable. Services revenue Services revenue primarily consists of fees for configuration services, consulting and training. The Company typically sells its services either on a fixed-fee or time-and-material basis. Services revenue is generally recognized as the services are performed for time and material contracts, or on a proportional performance basis for fixed-price contracts. Training revenue is recognized as the services are rendered. Significant judgments are required in determining whether services contained in the Company's customer subscription contracts are considered distinct, including whether the services are capable of being distinct and whether they are separately identifiable. Services deemed to be distinct are accounted for as a separate performance obligation on a relative standalone selling price basis and revenue is recognized as the services are performed. If services are determined not to be distinct, the services and the subscription are considered to be a single performance obligation and revenue is recognized over the contractual term of the subscription beginning on the date subscription services are made available to the customer. The associated revenue is allocated between subscription and services. Customer contracts with multiple performance obligations A portion of the Company's customer contracts contain multiple performance obligations. Significant judgment is required in determining whether multiple performance obligations contained in a single customer contract are capable of being distinct and are separately identifiable. An obligation determined to be distinct is accounted for as a separate performance obligation and revenue for that separate performance obligation is recognized when, or as, the Company satisfies the performance obligation. If obligations are determined not to be distinct, those obligations are accounted for as a single, combined performance obligation. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. Disaggregation of revenue The Company categorizes revenue from external customers by geographic area based on the location of the customer's headquarters. For additional information regarding the Company's revenue by geography, see Note 19 to the Consolidated Financial Statements.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency The Company has certain contracts denominated in foreign currencies and therefore a portion of the Company’s revenue is subject to foreign currency risks. Gains and losses from foreign currency transactions, such as those resulting from the settlement of receivables, are classified in other income, net included in the accompanying Consolidated Statements of Comprehensive Income (Loss). The functional currency of PROS France SAS ("PROS France") is the Euro. The financial statements of this subsidiary are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, historical rates of exchange for equity, and average rates of exchange for the p eriod for revenue and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity (deficit).
Noncash share-based compensation	Noncash Share-Based Compensation The Company's Amended and Restated 2017 Equity Incentive Plan (the "2017 Stock Plan") provides for noncash share-based compensation through the grant of: (i) restricted stock awards; (ii) restricted stock unit awards - time, performance and market-based ("RSUs"); (iii) stock options; (iv) stock appreciation rights ("SARs"); (v) phantom stock; and (vi) performance awards, such as market stock units ("MSUs"). To date, the Company has granted RSUs and MSUs from this plan. The Company issues common stock from its pool of authorized stock upon exercise of stock options, settlement of SARs and MSUs or upon vesting of RSUs. In November 2021, the Company granted inducement awards in an aggregate amount of 332,004 shares in accordance with NYSE Rule 303A.08. These inducement awards were in the form of RSUs granted to certain new employees in connection with the acquisition of EveryMundo. As part of the EveryMundo acquisition in November 2021, the purchase agreement included equity consideration of 273,120 shares of the Company's common stock to be issued to the recipients contingent on their employment with the Company during a two-year period. Based on the underlying agreements, this portion of the consideration was determined to represent post-combination noncash share-based compensation expense from an accounting perspective as opposed to purchase consideration. The following table presents the number of awards outstanding for each award type as of December 31, 2022 and 2021 (in thousands): Year Ended December 31, Award type 2022 2021 Restricted stock units (time-based) 2,235 2,145 Restricted stock units (performance-based) — 140 Market stock units 216 126 EveryMundo Equity consideration 137 273 Restricted stock units. The fair value of the RSUs (time-based and performance-based) is based on the closing price of the Company’s stock on the date of grant and is amortized over the vesting period. RSUs include (i) time-based awards and (ii) performance-based awards in which the number of shares that vest are based upon achievement of certain internal performance metrics set by the Company. Market stock units. MSUs are performance-based awards that vest based upon the Company’s relative shareholder return. The actual number of MSUs that will be eligible to vest is based on the total shareholder return of the Company relative to the total shareholder return of the Russell 2000 Index ("Index") over a 3-year period ending December 31, 2023 and December 31, 2024 ("Performance Period"), respectively. The MSUs will vest on January 31, 2024 and January 31, 2025, respectively. The maximum number of shares issuable upon vesting is 200% of the MSUs initially granted based on the average price of the Company's common stock relative to the Index during the Performance Period. The Company estimates the fair value of MSUs on the date of grant using a Monte Carlo simulation model. The determination of the fair value of the MSUs is affected by the Company’s stock price and a number of assumptions including the expected volatility of the Company’s stock and the Index, its risk-free interest rate and expected dividends. The Company’s expected volatility at the date of grant was based on the historical volatilities of the Company and the Index over the Performance Period. Equity consideration. The fair value of the equity consideration stock awards is based on the closing price of the Company’s stock on the date of grant and is amortized over the vesting period. If factors change and the Company employs different assumptions, noncash share-based compensation expense may differ significantly from what has been recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned noncash share-based compensation expense. Future noncash share-based compensation expense and unearned noncash share-based compensation will increase to the extent that the Company grants additional equity awards to employees. At December 31, 2022, there were an estimated $68.1 million of total unrecognized compensation costs related to noncash share-based compensation arrangements. These costs will be recognized over a weighted average period of 2.5 years. For further discussion of the Company’s noncash share-based compensation plans, see Note 14 to the Consolidated Financial Statements.
Income taxes	Income Taxes The Company uses the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. The Company reviews its deferred tax assets for recovery. A valuation allowance is esta blished when the Company believes it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in the Company’s tax provision in the period of change. The Company accounts for uncertain income tax positions recognized in an enterprise’s financial statements in accordance with the income tax topic of the ASC issued by the FASB. This interpretation requires companies to use a prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in its tax returns. This guidance provides clarification on recognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. The Company recognizes accrued interest and penalties related to income taxes, if any, as a component of income tax expense. For additional information regarding the Company’s income taxes, see Note 15
Segment Reporting, Policy [Policy Text Block]	Segment Reporting The Company reports as one operating segment with the Chief Executive Officer ("CEO") acting as the Company’s chief operating decision maker. The Company’s CEO reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has a single reporting unit, and there are no segment managers who are held accountable for operations, operating results or components below the consolidated unit level.
Earnings per share	Earnings Per ShareThe Company computes basic earnings (loss) per share by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding. Diluted earnings (loss) per share is computed by giving effect to all dilutive potential common shares outstanding during the period using the treasury stock method and convertible notes using the if-converted method. Dilutive potential common shares consist of shares issuable upon the exercise of stock options, shares of unvested restricted stock units, market stock units and equity consideration, and settlement of stock appreciation rights, if any. When the Company incurs a net loss, the effect of the Company's outstanding stock options, stock appreciation rights, restricted stock units, market stock units, equity consideration and convertible notes are not included in the calculation of diluted earnings (loss) per share as the effect would be anti-dilutive. Accordingly, basic and diluted net loss per share are identical.
Recent accounting pronouncements	Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08 , Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contract with Customers ("Topic 805") , which amends ASC 805 to require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. This new standard is effective for the Company's interim and annual periods beginning January 1, 2023, and earlier adoption is permitted. The Company early adopted Topic 805 in the fourth quarter of 2021 and there was no impact on the Company's Consolidated Financial Statements as of the adoption date. The Company appli ed the standard prospectively to the acquisition of EveryMundo which occurred in November 2021. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options ("Subtopic 470-20") and Derivatives and Hedging - Contracts in an Entity's Own Equity ("Subtopic 815-40") , which simplifies the accounting for certain convertible instruments, amends the guidance on derivative scope exceptions for contracts in an entity's own equity, and modifies the guidance on diluted earnings per share calculations as a result of these changes. This new standard is effective for the Company's interim and annual periods beginning January 1, 2022, and earlier adoption is permitted on January 1, 2021. The Company may elect to apply the amendments on a retrospective or modified retrospective basis. The Company early adopted the new standard effective January 1, 2021 on the modified retrospective basis. The adoption decreased additional paid-in capital by $80.1 million related to the equity conversion component of the outstanding convertible notes which was previously separated and recorded in equity, and increased convertible debt, net by $68.8 million related to the removal of the debt discounts and adjustment of debt issuance cost recorded under the previous standard. The net cumulative effect of the adjustments of $11.3 million was recorded as a decrease to the opening balance of the accumulated deficit as of January 1, 2021. As a result of the adoption, the noncash interest expense was lower for the year ended December 31, 2022 and will be lower for the remaining term of the outstanding convertible notes. The adoption had no impact on the Consolidated Statements of Cash Flows. Consolidated Financial Statements for the year ended December 31, 2020 remain as previously reported. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("Topic 326") , in order to improve financial reporting of expected credit losses on financial instruments and other commitments to extend credit. Topic 326 requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in current GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The Company adopted Topic 326 as of January 1, 2020 using the modified retrospective method and there was no material impact on the Company's Consolidated Financial Statements as of the adoption date. Recent Accounting Pronouncements With the exception of the new standards discussed above, there have been no other recent accounting pronouncements or changes in accounting pronouncements during the year ended December 31, 2022, that are of significance or potential significance to the Company.
