Accounting Policies [Abstract]
Nature of Business	Nature of Business Rimini Street, Inc. (the “Company”) is a global provider of end-to-end enterprise software support, products and services.
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The Unaudited Condensed Consolidated Financial Statements, which include the accounts of the Company and its wholly-owned subsidiaries, are prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”). All significant intercompany balances and transactions have been eliminated. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by U.S. GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the Unaudited Condensed Consolidated Financial Statements have been included. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s Audited Consolidated Financial Statements for the year ended December 31, 2022, included in the Company’s 2022 Annual Report on Form 10-K as filed with the SEC on March 1, 2023 (the “2022 Form 10-K”). The accompanying Unaudited Condensed Consolidated Balance Sheet and related disclosures as of December 31, 2022 have been derived from the Company’s audited financial statements. The Company’s financial condition as of March 31, 2023, and operating results for the three months ended March 31, 2023, are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period or for the year ending December 31, 2023.
Use of Estimates	Use of Estimates The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires the Company to make judgments, assumptions, and estimates that affect the amounts reported in its consolidated financial statements and accompanying notes. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes are reasonable under the circumstances to determine the carrying values of assets and liabilities that are not readily apparent from other sources. The Company’s accounting estimates include, but are not necessarily limited to, valuation of accounts receivable, valuation assumptions for stock options and leases, deferred income taxes and the related valuation allowances, and the evaluation and measurement of contingencies. To the extent there are material differences between the Company’s estimates and actual results, the Company’s future consolidated results of operations may be affected.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Standards. The following accounting standards were adopted during fiscal year 2023: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and amended in December 2022 with ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU 2020-04 provides guidance to alleviate the burden in accounting for reference rate reform by allowing certain expedients and exceptions in applying U.S. GAAP to contracts, hedging relationships and other transactions impacted by reference rate reform. The provisions apply only to those transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. Adoption of the provisions of ASU 2020-04 are optional and are effective from March 12, 2020 through December 31, 2024, as amended by ASU 2022-06. During the three months ended March 31, 2023, the Company adopted the optional relief guidance provided under ASU 2020-04 after modifying its interest rate swap agreement in connection with the amendment of the Credit Facility to implement certain changes in the reference rate from LIBOR to the Secured Overnight Financing Rate (“SOFR”). The application of this expedient preserves the presentation of the derivative consistent with past presentation and did not have a material impact on our Unaudited Condensed Consolidated Financial Statements.
Earnings Per Share	The Company computes earnings per share in accordance with ASC Topic 260, Earnings per Share. Basic earnings per share of Common Stock is computed by dividing net income attributable to common stockholders by the weighted average number of shares of basic Common Stock outstanding. Diluted earnings per share of Common Stock is calculated by adjusting the basic earnings per share of Common Stock for the effects of potential dilutive Common Stock shares outstanding such as stock options, restricted stock units and warrants.
