Accounting Policies [Abstract]
THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES	The Company and Significant Accounting Policies The Company 8x8, Inc. ("8x8" or the "Company") was incorporated in California in February 1987 and was reincorporated in Delaware in December 1996. The Company trades under the symbol "EGHT" on the Nasdaq Global Select Market. The Company is a leading Software-as-a-Service ("SaaS") provider of contact center, voice, video, chat, and enterprise-class API solutions powered by one global cloud communications platform. 8x8 empowers workforces worldwide by connecting individuals and teams, so they can collaborate faster and work smarter from anywhere. 8x8 provides real-time business analytics and intelligence, giving its customers unique insights across all interactions and channels on its platform, so they can support a distributed and hybrid working model while delighting their end-customers and accelerating their business. A majority of all revenue is generated from communication services subscriptions and platform usage. The Company also generates revenue from sales of hardware and professional services, which are complementary to the delivery of its integrated technology platform. Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. Accordingly, certain information and disclosures normally included in the Company's annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2026 and notes thereto included in the Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. The Company conducts its operations through one operating and reportable segment. In the opinion of the Company's management, these condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the Company's financial position, results of operations and cash flows for the periods presented. 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 March 31, 2027. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity, 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. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to revenue recognition, current expected credit losses, returns reserve for expected cancellations, fair value of and/or potential impairment of goodwill and value and useful life of long-lived assets (including intangible assets and right-of-use assets), capitalized internal-use software costs, benefit period for deferred contract acquisition costs, stock-based compensation, incremental borrowing rate used to calculate operating lease liabilities, convertible senior notes fair value, litigation, and other contingencies. The Company bases its estimates on known facts and circumstances, historical experience, and various other assumptions. Actual results could differ from those estimates under different assumptions or conditions. Significant Accounting Policies There have been no material changes from the significant accounting policies previously disclosed in Part II, Item 8 of the Form 10-K, except for the following: Net Income (Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) available to stockholders (numerator) by the weighted average number of vested, unrestricted shares of common stock outstanding during the period (denominator). Diluted net income per share is computed on the basis of the weighted average number of shares of common stock, plus the effect of dilutive potential shares of common stock outstanding during the period. Dilutive potential shares of common stock from stock options, shares under the Amended and Restated 1996 Employee Stock Purchase Plan (the "ESPP"), Restricted Stock Units ("RSUs"), Performance Stock Units ("PSUs") and warrants are computed using the treasury stock method. Potential shares of common stock attributable to the Company's convertible senior notes due 2028 (the "2028 Notes") as discussed below in Note 8, Convertible Senior Notes and Term Loan, are evaluated using the if-converted method, which requires testing both cash and share settlement assumptions and applying the more dilutive result. For periods where a net loss was recognized, basic and diluted net loss per share are the same, as the effect of potential shares of common stock would be anti-dilutive. Change in Reporting Presentation The Company has revised its anti-dilutive shares disclosure for the three months ended June 30, 2025 to include approximately 28.2 million potential shares of common stock attributable to its 2028 Notes. These shares are anti-dilutive in all periods presented under the if-converted method. This revision had no impact on basic or diluted net loss per share and the condensed consolidated financial statements for any period presented. See Note 11, Net Loss Per Share, for further details. Recently Adopted Accounting Pronouncements In November 2024, the FASB issued ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies whether the induced conversion guidance can be applied to the settlement of a convertible debt instrument that does not require the issuance of equity securities upon conversion. This update is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company has adopted ASU 2024-04 on a prospective basis, and this ASU does not have a material impact on the condensed consolidated financial statements. In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, providing a practical expedient to calculating current expected credit loss by assuming that the current conditions as of the balance sheet date will not change for the remaining life of the asset. This expedient can only be applied to current accounts receivable and current contract assets. This update is effective for annual reporting periods beginning after December 15, 2025, and interim periods within those annual reporting periods, and this update is applied prospectively. The Company has elected the expedient and adopted ASU 2025-05 on a prospective basis during the three months ended June 30, 2026. This ASU does not have a material impact on the condensed consolidated financial statements. Recently Issued Not Yet Adopted Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (Topic 220): Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures, and issued subsequent amendments to the implementation guidance (including ASU 2025-01), which requires companies to disclose additional information about specific expense categories in the notes to financial statements. This guidance will be effective for the Company's annual disclosures beginning for the fiscal year ending March 31, 2028 and for interim period disclosures beginning in the fiscal year ending March 31, 2029. The Company is currently evaluating the impact this guidance will have on the presentation of its condensed consolidated financial statements and accompanying notes. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which updates the accounting model by replacing the project stage approach with a probable-to-complete threshold, relocates website development guidance into Subtopic 350-40, and requires enhanced disclosures for capitalized software costs. This guidance will be effective for the Company's interim and annual disclosures beginning for the fiscal year ending March 31, 2029. The Company is currently evaluating the impact this guidance will have on its condensed consolidated financial statements and accompanying notes. There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three months ended June 30, 2026 that are of significance or potential significance to us.
