Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1. Description of Business and Summary of Significant Accounting Policies Description of Business RingCentral, Inc. (the “Company”) is a provider of software-as-a-service (“SaaS”) solutions that enables businesses to communicate, collaborate and connect. The Company was incorporated in California in 1999 and was reincorporated in Delaware on September 26, 2013. Basis of Presentation and Consolidation The Company's unaudited condensed consolidated financial statements and accompanying notes reflect all adjustments (all of which are normal, recurring in nature and those discussed in these notes) that are, in the opinion of management, necessary for a fair presentation of the interim periods presented. All intercompany balances and transactions have been eliminated in consolidation. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending December 31, 2022. Certain information and note disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 1, 2022. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The significant estimates made by management affect revenues, the allowance for doubtful accounts, valuation of long-term investments, deferred and prepaid sales commission costs, goodwill, useful lives of intangible assets, share-based compensation, capitalization of internally developed software, liability and equity allocation of convertible senior notes, return reserves, provision for income taxes, uncertain tax positions, loss contingencies, sales tax liabilities and accrued liabilities. Management periodically evaluates these estimates and will make adjustments prospectively based upon the results of such periodic evaluations. Actual results may differ from these estimates. In particular, the Company evaluates its deferred and prepaid sales commission balances for possible recoverability whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable, and as a result of the uncertainty regarding Avaya’s financial condition, the Company performed a recoverability assessment based on the facts and circumstances known to date. There can be no assurances that the Company’s current estimates are accurate or will not subsequently need to be revised as additional information regarding Avaya’s financial status and condition is made publicly available. Refer to Note 3, Financial Statement Components in this Quarterly Report on Form 10-Q for further information regarding our assessment of the recoverability of our deferred and prepaid sales commission balances with Avaya. Segment Information The Company has determined that the chief executive officer is the chief operating decision maker. The Company’s chief executive officer reviews financial information presented on a consolidated basis for purposes of assessing performance and making decisions on how to allocate resources. Accordingly, the Company has determined that it operates in a single reportable segment. Concentrations As of September 30, 2022 and December 31, 2021, none of the Company’s customers accounted for more than 10% of the Company’s total accounts receivable. Long-lived assets by geographic location are based on the location of the legal entity that owns the asset. As of September 30, 2022 and December 31, 2021, approximately 95% of the Company’s consolidated long-lived assets were located in the U.S. No other single country outside of the U.S. represented more than 10% of the Company’s consolidated long-lived assets. Recent Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued optional guidance for a limited time to ease the potential burden in accounting for or recognizing the effects of reference rate reform, particularly, the risk of cessation of the London Interbank Offered Rate (“LIBOR”) on financial reporting. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are elective and are effective upon issuance for all entities through December 31, 2022. The amendments in this ASU are not expected to have a material impact on the Company's consolidated financial statements. Recently Adopted Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity. This update simplifies the accounting for convertible instruments by eliminating the conversion option separation model for convertible debt that can be settled in cash. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This update also eliminates the treasury stock method and instead requires entities to calculate the impact of convertible instruments on diluted earnings per share when the instruments may be settled in cash or shares. The required use of the if-converted method did not impact the diluted net loss per share as the Company was in a net loss position. The Company adopted this update, effective January 1, 2022, using the modified retrospective method. Upon adoption, the Company is no longer recording the conversion feature of its convertible senior notes in equity. Instead, the Company combined the previously separated equity component with the liability component, which together is now classified as debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and amortized as interest expense. Accordingly, the Company recorded a decrease to accumulated deficit of approximately $93.8 million, a decrease to additional paid-in capital of $329.3 million, and an increase to convertible senior notes, net of approximately $235.5 million. Prior period financial statements were not restated.

Amortization of developed technology is included in cost of revenues and amortization of customer relationships is included in sales and marketing expenses in the Condensed Consolidated Statements of Operations. Estimated amortization expense for acquired intangible assets for the following fiscal years is as follows (in thousands): 2022 (remaining) $ 41,198 2023 150,457 2024 147,099 2025 132,930 2026 onwards 113,057 Total estimated amortization expense $ 584,741 Accrued liabilities consisted of the following (in thousands): September 30, 2022 December 31, 2021 Accrued compensation and benefits $ 45,286 $ 48,911 Accrued sales, use, and telecom related taxes 37,557 30,463 Accrued marketing 68,278 52,547 Operating lease liabilities, short-term 16,685 18,686 Other accrued expenses 173,450 129,191 Total accrued liabilities $ 341,256 $ 279,798 Deferred and Prepaid Sales Commission Costs Amortization expense for the deferred and prepaid sales commission costs was $31.5 million and $19.9 million for the three months ended September 30, 2022 and 2021, respectively, and $81.5 million and $53.3 million for the nine months ended September 30, 2022 and 2021, respectively. There was no impairment loss in relation to the deferred commissions costs capitalized for the periods presented. In October 2019, the Company entered into certain agreements for a strategic partnership with Avaya Holdings Corp. (“Avaya”) and its subsidiaries, including Avaya Inc. In connection with the strategic partnership, the Company prepaid Avaya in the Company's class A Common Stock predominantly for future sales commission to be earned for each qualified unit of Avaya Cloud Office by RingCentral (“ACO”) sold during the term of the partnership. The unutilized prepaid sales commission is refundable and payable to the Company at the end of the contractual term. Avaya recently disclosed in its earnings release, among other things, a substantial doubt about its ability to continue as a “going concern.” While Avaya provided preliminary third quarter financial information and related disclosures, it also indicated that it would be unable to timely file its Form 10-Q for the quarter ended June 30, 2022. Avaya has not made any additional financial information publicly available with respect to its third quarter or its financial results for its fiscal year ended September 30, 2022. The Company evaluates the recoverability of its deferred and prepaid sales commission balance whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Avaya continues to sell the ACO product and earn sales commissions, which the Company is applying against the prepaid sales commission balance, but as a result of the uncertainty regarding Avaya’s financial condition, the Company performed a recoverability assessment based on the facts and circumstances known to date. While the Company lacks Avaya's financial information, in light of Avaya's public disclosures, the Company has recorded a non-cash asset write-down charge of $124.9 million, out of which $21.7 million of this balance is accrued interest and is recorded in other expenses in the Condensed Consolidated Statement of Operations. As of September 30, 2022, the remaining prepaid sales commission balance was $162.2 million. The Company will continue to evaluate the recoverability of the assets on an ongoing basis and if the evaluation indicates that the carrying amount of the assets is not recoverable, the Company may incur significant incremental write down charges in the future.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 4. Fair Value of Financial Instruments The Company measures and reports certain cash equivalents, including money market funds and certificates of deposit, in addition to its long-term investments at fair value in accordance with the provisions of the authoritative accounting guidance that addresses fair value measurements. This guidance establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: Level 1: Observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Other inputs, such as quoted prices for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3: Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques. The financial assets carried at fair value were determined using the following inputs (in thousands): Fair Value at Level 1 Level 2 Level 3 Cash equivalents: Money market funds $ 214,565 $ 214,565 $ — $ — Non-current assets: Long-term investments $ 28,911 $ — $ — $ 28,911 Fair Value at Level 1 Level 2 Level 3 Cash equivalents: Money market funds $ 175,663 $ 175,663 $ — $ — Non-current assets: Long-term investments $ 199,965 $ — $ — $ 199,965 Marketable equity investments $ 8,600 $ 8,600 $ — $ — The Company’s other financial instruments, including accounts receivable, accounts payable, and other current liabilities, are carried at cost, which approximates fair-value due to the relatively short maturity of those instruments. Long-Term Investments As of September 30, 2022 and December 31, 2021, t he fair value of the Company's long-term investments in convertible and redeemable preferred stock issued by Avaya was $28.9 million and $200.0 million , respectively. The Company classifies these investments as Level 3 in the fair value hierarchy based on the nature of the fair value inputs and judgment involved in the valuation process. The Company uses a lattice model to value these investments and relies on observable inputs including share-price, credit spread, and volatility. The model also incorporates judgments relating to the probability of special redemption triggers, the expected holding period of the investment, interest rates, and expected recoverability. These investments are reported at fair value in long-term investments in the Condensed Consolidated Balance Sheets with net unrealized gain (loss) recorded in other expense . The Company recognized an unrealized loss of $77.4 million and $48.7 million for the three months ended September 30, 2022 and 2021, respectively, and a net unrealized loss of $174.0 million and $15.3 million for the nine months ended September 30, 2022 and 2021, respectively. In determining the fair value of the investment, the Company also considered Avaya's recent public disclosures. Volatility in the global economic climate and financial markets, including the effects of rising inflation and associated economic slowdown, the ongoing Russian invasion of Ukraine, and the investee's financial and liquidity position, could result in a significant change in the underlying share-price of the Company’s investee and their financial position, resulting in a material change in the value of the long-term investments, requiring impairment charges. Marketable Equity Investments During the three months ended September 30, 2022, the Company completed the sale of its marketable equity investments for proceeds of $3.2 million. During the three and nine months ended September 30, 2022, the Company recognized a loss from its marketable equity investments of $1.8 million and $5.4 million , respectively, which was reported in other expense in the Condensed Consolidated Statement of Operations. Other Non-Marketable Investments As of September 30, 2022, the Company had an immaterial amount of non-marketable investments held in debt and equity securities without readily determinable fair values in which it had neither a controlling interest nor significant influence. These investments are carried at cost under the measurement alternative as part of long-term investments in the Condensed Consolidated Balance Sheets. Convertible Senior Notes As of September 30, 2022, the fair value of the 0% convertible senior notes due 2026 (the “2026 Notes”) was approximately $498.8 million, and 0% convertible senior notes due 2025 (the “2025 Notes”) was approximately $840.8 million. The fair value for the convertible notes was determined based on the quoted price for such notes in an inactive market on the last trading day of the reporting period and is considered as Level 2 in the fair value hierarchy.

Convertible Senior Notes	Note 5. Convertible Senior Notes In March 2018, the Company issued $460.0 million aggregate principal amount of 0% convertible senior notes due 2023 in a private placement, including the exercise in full of the over-allotment options of the initial purchasers (the "2023 Notes"). The 2023 Notes would have matured on March 15, 2023, unless repurchased or redeemed earlier by the Company or converted pursuant to their terms. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $449.5 million. In the second quarter of 2021, the Company redeemed the remaining outstanding principal balance of its 2023 Notes. In March 2020, the Company issued $1.0 billion aggregate principal amount of 0% convertible senior notes due 2025 in a private placement to qualified institutional buyers (the "2025 Notes"). The 2025 Notes will mature on March 1, 2025, unless earlier repurchased or redeemed by the Company or converted pursuant to their terms. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $986.5 million. In September 2020, the Company issued $650.0 million aggregate principal amount of 0% convertible senior notes due 2026 in a private placement to qualified institutional buyers (the "2026 Notes"). The 2026 Notes will mature on March 15, 2026, unless earlier repurchased or redeemed by the Company or converted pursuant to their terms. The total net proceeds from the debt offering, after deducting initial purchase discounts and debt issuance costs, were approximately $640.2 million. The 2023 Notes, 2025 Notes and 2026 Notes (collectively, the “Notes”) are senior, unsecured obligations of the Company that do not bear regular interest, and the principal amount of the Notes do not accrete. The Notes may bear special interest under specified circumstances relating to the Company's failure to comply with its reporting obligations under the indentures governing each of the Notes (collectively, the "Notes Indentures") or if the Notes are not freely tradeable as required by each respective Notes Indenture. Other Terms of the Notes 2025 Notes 2026 Notes $1,000 principal amount initially convertible into number of the Company’s Class A Common Stock, par value $0.0001 2.7745 shares 2.3583 shares Equivalent initial approximate conversion price per share $ 360.43 $ 424.03 The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for any accrued and unpaid special interest. In addition, upon the occurrence of a make-whole fundamental change or a redemption period, each as defined in the respective Notes Indentures, the Company will, in certain circumstances, increase the conversion rate by a number of additional shares for a holder that elects to convert its Notes in connection with such make-whole fundamental change or during the relevant redemption period. The Notes will be convertible at certain times and upon the occurrence of certain events in the future. Further, on or after December 1, 2024 for the 2025 Notes, and December 15, 2025 for the 2026 Notes, until the close of business on the scheduled trading day immediately preceding the maturity date, holders of the Notes may convert all or a portion of their notes regardless of these conditions. Under the terms of the respective Notes Indentures, effective January 1, 2022, the Company made an irrevocable election to settle the principal portion of the Notes only in cash, with the conversion premium to be settled in cash or shares. During the three months ended September 30, 2022, the conditions allowing holders of the 2025 Notes and 2026 Notes to convert were not met. The Notes may be convertible thereafter if one or more of the conversion conditions specified in the indentures are satisfied during future measurement periods. The Company may redeem the Notes at its option, on or after March 5, 2022 for the 2025 Notes, and March 20, 2023 for the 2026 Notes, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid special interest to, but excluding the redemption date, subject to certain conditions. No sinking fund is provided for the Notes. Upon the occurrence of a fundamental change (as defined in each respective Notes Indentures) prior to the maturity date, holders may require the Company to repurchase all or a portion of the 2025 Notes or 2026 Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased, plus any accrued and unpaid special interest to, but excluding, the fundamental change repurchase date. The net carrying amount of the liability component of the Notes as of September 30, 2022 were as follows (in thousands): 2025 Notes 2026 Notes Principal $ 1,000,000 $ 650,000 Unamortized issuance cost (6,555) (6,152) Net carrying amount (1) $ 993,445 $ 643,848 (1) The net carrying amount was increased on January 1, 2022 as a result of the adoption of ASU No. 2020-06. Refer to Note 1, Description of Business and Summary of Significant Accounting Policies , in this Quarterly Report on Form 10-Q for further information. The following table sets forth the total interest expense recognized related to the Notes (in thousands): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Amortization of debt discount (1) $ — $ 15,122 $ — $ 45,645 Amortization of debt issuance cost (1) 1,118 776 3,350 2,335 Total interest expense related to the Notes (1) $ 1,118 $ 15,898 $ 3,350 $ 47,980 (1) The decrease in total interest expense during the three and nine months ended September 30, 2022 was due to the derecognition of the unamortized debt discount, partially offset by the increase in the amortization of issuance costs previously recognized in equity. These changes were the result of the Company’s adoption of ASU No. 2020-06, as of January 1, 2022, as described in Note 1, Description of Business and Summary of Significant Accounting Policies. Capped Calls In connection with the offering of the Notes, the Company entered into privately-negotiated capped call transactions relating to each series of notes with certain counterparties (collectively the “Capped Calls”). The initial strike price of the Notes corresponds to the initial conversion price of each of the Notes. The Capped Calls are generally intended to reduce or offset the potential dilution to the Class A Common Stock upon any conversion of the Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. The Capped Calls are subject to either adjustment or termination upon the occurrence of specified extraordinary events affecting the Company, including a merger event; a tender offer; and a nationalization, insolvency or delisting involving the Company. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including changes in law; insolvency filings; and hedging disruptions. The Capped Call transactions are recorded in stockholders’ equity and are not accounted for as derivatives. The following table below sets forth key terms and costs incurred for the Capped Calls related to each of the Notes: 2023 Notes 2025 Notes 2026 Notes Initial approximate strike price per share, subject to certain adjustments $ 81.45 $ 360.43 $ 424.03 Initial cap price per share, subject to certain adjustments $ 119.04 $ 480.56 $ 556.10 Net cost incurred (in millions) $ 49.9 $ 60.9 $ 41.8 Class A Common Stock covered, subject to anti-dilution adjustments (in millions) 5.6 2.8 1.5 Settlement commencement date 1/13/2023 1/31/2024 2/13/2025 Settlement expiration date 3/13/2023 2/28/2024 3/13/2025 All of the capped call transactions, including the capped call relating to the 2023 Notes, were outstanding as of September 30, 2022.

Commitments and Contingencies	Note 7. Commitments and Contingencies Legal Matters The Company is subject to certain legal proceedings described below, and from time to time may be involved in a variety of claims, lawsuits, investigations, and proceedings relating to contractual disputes, intellectual property rights, employment matters, regulatory compliance matters, and other litigation matters relating to various claims that arise in the normal course of business. The Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed probable and can be reasonably estimated. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using reasonably available information. The Company develops its views on estimated losses in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. Actual claims could settle or be adjudicated against the Company in the future for materially different amounts than the Company has accrued due to the inherently unpredictable nature of litigation. Legal fees are expensed in the period in which they are incurred. Patent Infringement Matter On April 25, 2017, Uniloc USA, Inc. and Uniloc Luxembourg, S.A. (together, “Uniloc”) filed in the U.S. District Court for the Eastern District of Texas two actions against the Company alleging infringement of U.S. Patent Nos. 7,804,948; 7,853,000; and 8,571,194 by RingCentral’s Glip unified communications application. The plaintiffs seek a declaration that the Company has infringed the patents, damages according to proof, injunctive relief, as well as their costs, attorney’s fees, expenses and interest. On October 9, 2017, the Company filed a motion to dismiss or transfer requesting that the case be transferred to the United States District Court for the Northern District of California. In response to the motion, plaintiffs filed a first amended complaint on October 24, 2017. The Company filed a renewed motion to dismiss or transfer on November 15, 2017. Although briefing on that motion has been completed, the motion has not yet been decided. On February 5, 2018, Uniloc moved to stay the litigation pending the resolution of certain third-party inter partes review proceedings (“IPRs”) before the United States Patent and Trademark Office. On February 9, 2018, the court stayed the litigation pending resolution of the IPRs without prejudice to or waiver of the Company’s motion to dismiss or transfer. This litigation is still in its early stages. Based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company’s condensed consolidated financial statements, it is not possible to provide an estimated amount of any such loss or range of loss that may occur. The Company intends to vigorously defend against this lawsuit. CIPA Matter On June 16, 2020, Plaintiff Meena Reuben (“Reuben”) filed a complaint against the Company for a putative class action lawsuit in California Superior Court for San Mateo County. The complaint alleges claims on behalf of a class of individuals for whom, while they were in California, the Company allegedly intercepted and recorded communications between individuals and the Company’s customers without the individual’s consent, in violation of the California Invasion of Privacy Act (“CIPA”) Sections 631 and 632.7. Reuben seeks statutory damages of $5,000 for each alleged violation of Sections 631 and 632.7, injunctive relief, and attorneys’ fees and costs, and other unspecified amount of damages. On July 7, 2020, the Court granted the parties’ stipulation to extend time for the Company to respond to the Reuben’s complaint. The parties participated in mediation on August 24, 2021. On September 16, 2021, Reuben filed an amended complaint. The Company filed a demurrer to the amended complaint on October 18, 2021. Reuben filed her opposition on November 8, 2021, and the Company filed its reply on November 22, 2021. A hearing was held on January 6, 2022. The Court overruled the Company’s demurrer and the parties are now engaged in discovery. This litigation is still in its early stages. Based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company’s condensed consolidated financial statements, it is not possible to provide an estimated amount of any such loss or range of loss that may occur. The Company intends to vigorously defend against this lawsuit. Other Matter On June 14, 2019, the Company filed suit in the Superior Court of California, County of Alameda, against Bright Pattern, Inc. and two of its officers, alleging that the defendants negotiated a potential acquisition of Bright Pattern by RingCentral fraudulently and in bad faith. The Company seeks its costs incurred in negotiating under the Letter of Intent (“LOI”) that the parties entered into and damages for lost opportunity as a result of forgoing another acquisition opportunity, and attorneys’ fees and costs. On August 26, 2019, Bright Pattern filed a cross-complaint against the Company and two of its executive officers alleging breach of the LOI as well as tort claims arising from the Company's allegedly inducing Bright Pattern to enter into the LOI and subsequent extensions while allegedly misstating the timeframe for the proposed transaction. As damages, Bright Pattern seeks audit fees it allegedly incurred, a $5 million break-up fee, its alleged “cash burn” during the negotiations, and unspecified lost opportunity damages. The Company filed a demurrer to Bright Pattern’s amended cross-complaint, as well as a related motion to strike. On May 7, 2020, the court denied both the motion to strike and demurrer. On July 19, 2022, the parties filed a joint motion to stay the proceedings, which the court granted on July 20, 2022. Based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company’s condensed consolidated financial statements, it is not possible to provide an estimated amount of any loss or range of loss that may occur. The Company intends to vigorously prosecute and defend this lawsuit.

Stockholders' Deficit and Convertible Preferred Stock	Note 8. Stockholders’ Deficit and Convertible Preferred Stock Share Repurchase Program On December 13, 2021, the Company's board of directors authorized a share repurchase program under which it may repurchase up to $100 million of the Company's outstanding shares of Class A Common Stock. Under the program, share repurchases may be made at the Company's discretion from time to time in open market transactions, privately negotiated transactions, or other means. The program does not obligate the Company to repurchase any specific dollar amount or to acquire any specific number of shares of its Class A Common Stock. The timing and number of any shares repurchased under the program will depend on a variety of factors, including stock price, trading volume, and general business and market conditions. The authorization is effective until December 31, 2022. During the three and nine months ended September 30, 2022, the Company repurchased and subsequently retired 419,214 and 840,255 shares of our Class A Common Stock, respectively, for an aggregate amount of $20.0 million and $45.0 million, respectively. As of September 30, 2022, $55.0 million remained available under the Company's share repurchase authorization. Series A Convertible Preferred Stock On November 8, 2021, the Company entered into the Investment Agreement, pursuant to which the Company sold to Searchlight Investor, in a private placement exempt from registration under the Securities Act of 1933, as amended, 200,000 shares of newly-issued Series A Convertible Preferred Stock, par value $0.0001 per share, for an aggregate purchase price of $200 million. The Series A Convertible Preferred Stock issued to Searchlight Investor pursuant to the Investment Agreement is convertible into shares of the Company's Class A Common Stock, par value $0.0001 per share, at a conversion price of $269.22 per share, subject to adjustment as provided in the certificate of designations specifying the terms of such shares. The transactions contemplated by the Investment Agreement closed on November 9, 2021. The Series A Convertible Preferred Stock ranks senior to the shares of the Company’s Class A Common Stock and Class B Common Stock with respect to rights on the distribution of assets on any voluntary or involuntary liquidation or winding up of the affairs of the Company. The Series A Convertible Preferred Stock is a zero coupon, perpetual preferred stock, with a liquidation preference of $1,000 per share and other customary terms, including with respect to mandatory conversion and change of control premium under certain circumstances. The shares of Series A Convertible Preferred Stock shall not be redeemable or otherwise mature, other than for a liquidation or a specified change in control event as provided in the certificate of designations specifying the terms of such shares. Holders of Series A Convertible Preferred Stock will be entitled to vote with the holders of the Class A Common Stock and Class B Common Stock on an as-converted basis.

The total intrinsic value of options exercised during the nine months ended September 30, 2022 and 2021 was $13.3 million and $122.5 million, respectively. There is no remaining unamortized share-based compensation expense. Employee Stock Purchase Plan The Company's Employee Stock Purchase Plan (“ESPP”) allows eligible employees to purchase shares of the Company’s Class A Common Stock at a discounted price through payroll deductions. As of September 30, 2022, there was a total of $0.8 million of unrecognized share-based compensation expense, net of estimated forfeitures, related to the ESPP, which will be recognized on a straight-line basis over the remaining weighted-average vesting period of approximately 0.1 years.

Income Tax Disclosure [Abstract]
Income Taxes	Note 10. Income Taxes The provision for income taxes was $0.9 million and $0.6 million for the three months ended September 30, 2022 and 2021, respectively, and $2.9 million and $1.4 million for the nine months ended September 30, 2022 and 2021, respectively. The provision for income taxes for the three and nine months ended September 30, 2022 and 2021 consisted primarily of foreign income taxes and state minimum taxes. For the three and nine months ended September 30, 2022 and 2021, the provision for income taxes differed from the U.S. federal statutory rate primarily due to foreign and state taxes currently payable. The Company realized no benefit for the current year losses due to the full valuation allowance against the U.S. and foreign net deferred tax assets in certain foreign jurisdictions. The realization of tax benefits of net deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that certain net deferred tax assets will be realizable. Accordingly, the Company continues to provide a full valuation allowance against the entire domestic and the majority of the foreign net deferred tax assets as of September 30, 2022 and December 31, 2021. The Company intends to maintain the full valuation allowance on the U.S. and certain foreign net deferred tax assets until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three and nine months ended September 30, 2022, there were no material changes to the total amount of unrecognized tax benefits. The 2017 Tax Cuts and Jobs Act amended Sec. 174 to require that specified research and experimental (SR&E) expenditures be capitalized and amortized over five years or fifteen years depending on where the expenditures are incurred. This provision applies to tax years beginning on or after January 1, 2022. Additionally, the final FTC regulations were published in the Federal Register on January 4, 2022 which resulted in significant changes and updates for allocation and apportionment of foreign taxes, creditability of foreign taxes and other provisions affecting FTC calculation. The final FTC regulations are generally effective for foreign taxes paid or accrued in tax years beginning on or after December 28, 2021. Due to full valuation allowance position and taxable loss for the US jurisdiction, the Company does not believe that either of these new provisions will have a material impact on its financial statements.

Earnings Per Share [Abstract]
Basic and Diluted Net Loss Per Share	Note 11. Basic and Diluted Net Loss Per Share Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, stock options, restricted stock units, ESPP, convertible senior notes, and convertible preferred stock, to the extent dilutive. For the three and nine months ended September 30, 2022 and 2021, all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive. The following table sets forth the computation of the Company’s basic and diluted net loss per share of common stock (in thousands, except per share data): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Numerator Net loss $ (284,616) $ (146,751) $ (595,103) $ (257,893) Denominator Weighted-average common shares outstanding for basic and diluted net loss per share 95,575 91,811 95,097 91,213 Basic and diluted net loss per share $ (2.98) $ (1.60) $ (6.26) $ (2.83) The following table summarizes the potentially dilutive common shares that were excluded from diluted weighted-average common shares outstanding because including them would have had an anti-dilutive effect (in thousands): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Shares of common stock issuable under equity incentive plans outstanding 4,064 4,276 3,703 3,955 Shares of common stock related to convertible preferred stock 743 — 743 — Shares of common stock related to convertible senior notes — — — 179 Potential common shares excluded from diluted net loss per share 4,807 4,276 4,446 4,134 Under the terms of the respective Notes Indentures, effective January 1, 2022, the Company made an irrevocable election to settle the principal portion of the Notes only in cash, with the conversion premium to be settled in cash or shares. Upon the adoption of ASU No. 2020-06 on January 1, 2022, the Company calculates the potential dilutive effect of its 2025 Notes and 2026 Notes under the if-converted method. Under this method, only the amounts settled in excess of the principal will be considered in diluted earnings per share, in line with the terms of the Notes Indentures.

Subsequent Events Date of Annual Meeting of Stockholders On November 3, 2022, the Company filed a Form 8-K with the SEC announcing that the Company’s board of directors scheduled the Company’s annual meeting of stockholders for December 15, 2022. Amended and Restated Bylaws On and effective November 7, 2022, the Company’s board of directors adopted amendments to the Amended and Restated Bylaws. The amendments, among other things, enhance disclosure and procedural requirements in connection with stockholder nominations of directors in accordance with Rule 14a-19 under the Exchange Act of 1934, as amended. Costs Associated with Exit or Disposal Activities On November 7, 2022, the Company’s board of directors approved a reduction in force plan (the “Plan”) as part of broader efforts to align the Company’s cost base with its strategic priorities in the current environment. The Plan is expected to reduce the Company’s full-time employees by approximately 10%. The Company estimates the aggregate restructuring costs associated with the Plan to be approximately $10.0 million to $15.0 million, primarily consisting of severance payments, employee benefits and related costs. The Company expects to incur these charges in the fourth quarter of 2022 and the first quarter of 2023. The Company expects the reduction in force to be substantially complete by the first quarter of 2023, subject to local law and consultation requirements, which may extend the process beyond the first quarter of 2023 in certain countries. The Company may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur as a result of or in connection with the implementation of the Plan.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The Company's unaudited condensed consolidated financial statements and accompanying notes reflect all adjustments (all of which are normal, recurring in nature and those discussed in these notes) that are, in the opinion of management, necessary for a fair presentation of the interim periods presented. All intercompany balances and transactions have been eliminated in consolidation. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire year ending December 31, 2022. Certain information and note disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”).
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The significant estimates made by management affect revenues, the allowance for doubtful accounts, valuation of long-term investments, deferred and prepaid sales commission costs, goodwill, useful lives of intangible assets, share-based compensation, capitalization of internally developed software, liability and equity allocation of convertible senior notes, return reserves, provision for income taxes, uncertain tax positions, loss contingencies, sales tax liabilities and accrued liabilities. Management periodically evaluates these estimates and will make adjustments prospectively based upon the results of such periodic evaluations. Actual results may differ from these estimates. In particular, the Company evaluates its deferred and prepaid sales commission balances for possible recoverability whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable, and as a result of the uncertainty regarding Avaya’s financial condition, the Company performed a recoverability assessment based on the facts and circumstances known to date. There can be no assurances that the Company’s current estimates are accurate or will not subsequently need to be revised as additional information regarding Avaya’s financial status and condition is made publicly available. Refer to Note 3, Financial Statement Components in this Quarterly Report on Form 10-Q for further information regarding our assessment of the recoverability of our deferred and prepaid sales commission balances with Avaya.
Segment Information	Segment Information The Company has determined that the chief executive officer is the chief operating decision maker. The Company’s chief executive officer reviews financial information presented on a consolidated basis for purposes of assessing performance and making decisions on how to allocate resources. Accordingly, the Company has determined that it operates in a single reportable segment.
Concentrations	Concentrations As of September 30, 2022 and December 31, 2021, none of the Company’s customers accounted for more than 10% of the Company’s total accounts receivable. Long-lived assets by geographic location are based on the location of the legal entity that owns the asset. As of September 30, 2022 and December 31, 2021, approximately 95% of the Company’s consolidated long-lived assets were located in the U.S. No other single country outside of the U.S. represented more than 10% of the Company’s consolidated long-lived assets.
Recent Accounting Pronouncements Not Yet Adopted and Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued optional guidance for a limited time to ease the potential burden in accounting for or recognizing the effects of reference rate reform, particularly, the risk of cessation of the London Interbank Offered Rate (“LIBOR”) on financial reporting. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are elective and are effective upon issuance for all entities through December 31, 2022. The amendments in this ASU are not expected to have a material impact on the Company's consolidated financial statements. Recently Adopted Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity's Own Equity. This update simplifies the accounting for convertible instruments by eliminating the conversion option separation model for convertible debt that can be settled in cash. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. This update also eliminates the treasury stock method and instead requires entities to calculate the impact of convertible instruments on diluted earnings per share when the instruments may be settled in cash or shares. The required use of the if-converted method did not impact the diluted net loss per share as the Company was in a net loss position. The Company adopted this update, effective January 1, 2022, using the modified retrospective method. Upon adoption, the Company is no longer recording the conversion feature of its convertible senior notes in equity. Instead, the Company combined the previously separated equity component with the liability component, which together is now classified as debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and amortized as interest expense. Accordingly, the Company recorded a decrease to accumulated deficit of approximately $93.8 million, a decrease to additional paid-in capital of $329.3 million, and an increase to convertible senior notes, net of approximately $235.5 million. Prior period financial statements were not restated.
