Accounting Policies [Abstract]
Basis of Presentation, Significant Accounting Policies and Recently-Issued Accounting Pronouncements	Basis of Presentation, Significant Accounting Policies and Recently-Issued Accounting Pronouncements The accompanying unaudited condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the Securities and Exchange Commission (“SEC”) on February 23, 2023. The unaudited condensed consolidated financial statements are unaudited and have been prepared on a basis consistent with that used to prepare the audited annual consolidated financial statements and include, in the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair statement of the condensed consolidated financial statements. The unaudited condensed consolidated balance sheet at December 31, 2022 was derived from audited financial statements, but does not include all disclosures required by GAAP. The operating results for the quarter ended March 31, 2023 are not necessarily indicative of the results expected for the full year ending December 31, 2023. Use of estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, primarily those related to determining the stand-alone selling price for separate deliverables in the Company’s subscription revenue arrangements, allowance for doubtful accounts, cancellations and credits, fair value of assets and liabilities assumed in a business combination, recoverability of goodwill and long-lived assets, useful lives associated with long-lived assets and right-of-use assets, income taxes, contingencies, fair value of contingent consideration, fair value of convertible senior notes, redemption value of redeemable non-controlling interest, and the valuation and assumptions underlying stock-based compensation. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 at March 31, 2023 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s allowance for credit losses, and the carrying value of goodwill and other long-lived assets. While there was not a material impact to the Company’s consolidated financial statements for the quarter ended March 31, 2023, the Company’s future assessment of the magnitude and duration of COVID-19 and other factors could result in material impacts to the Company’s consolidated financial statements in future reporting periods. Significant accounting policies The Company’s significant accounting policies are detailed in “Note 2 - Significant Accounting Policies" of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. There have been no material changes to the Company’s significant accounting policies. Recently-adopted accounting pronouncements There have been no recently adopted accounting pronouncements since the filing of the Company's Annual Report on Form 10-K for the year ended December 31, 2022. Recently-issued accounting pronouncements The Company has evaluated all recent accounting pronouncements and believes that none of them will have a material effect on the company’s financial statements.

Equity Method Investments and Joint Ventures [Abstract]
Redeemable Non-Controlling Interest	Redeemable Non-Controlling Interest In September 2018, the Company entered into an agreement with Japanese Cloud Computing and M30 LLC (the “Investors”) to engage in the investment, organization, management, and operation of a Japanese subsidiary (“BlackLine K.K.”) of the Company that is focused on the sale of the Company's products in Japan. In October 2018, the Company initially contributed approximately $4.5 million in cash in exchange for 51% of the outstanding common stock of BlackLine K.K. In November 2021, the Company made a further investment in BlackLine K.K. of $2.3 million that, including additional investments in BlackLine K.K. of $2.2 million by existing third-party investors in November 2021, maintained the Company's majority ownership of 51%. As the Company continues to control a majority stake in BlackLine K.K., the entity has been consolidated. All of the common stock held by the Investors is callable by the Company or puttable by the Investors upon certain contingent events. Should the call or put option be exercised, the redemption value will be determined based upon a prescribed formula derived from the discrete revenues of BlackLine K.K. and the Company and may be settled, at the Company’s discretion, with Company stock or cash. As a result of the put right available to the Investors in the future, the redeemable non-controlling interest in BlackLine K.K. is classified outside of permanent equity in the Company’s consolidated balance sheets, and the balance is reported at the greater of the initial carrying amount adjusted for the redeemable non-controlling interest's share of earnings, or its estimated redemption value. The resulting changes in the estimated redemption amount are recorded within retained earnings or, in the absence of retained earnings, additional paid-in-capital. The following table summarizes the activity in the redeemable non-controlling interest for the periods indicated below: Quarter Ended March 31, 2023 2022 Balance at beginning of period $ 23,895 $ 28,699 Net income (loss) attributable to redeemable non-controlling interest (excluding adjustment to non-controlling interest) 85 (3) Foreign currency translation (20) (128) Adjustment to redeemable non-controlling interest 5,192 (3,417) Balance at end of period $ 29,152 $ 25,151

The valuation techniques used to measure the fair values of our instruments that were classified as Level 1 were derived from quoted market prices for identical instruments in active markets. The valuation techniques used to measure the fair values of Level 2 instruments were derived from broker reports that utilized quoted market prices for similar instruments. In conjunction with the 2013 Acquisition, option holders of BlackLine Systems, Inc. were allowed to cancel their stock option rights and receive a cash payment equal to the amount of calculated gain (less applicable expense and other items) had they exercised their stock options and then sold their common shares as part of the 2013 Acquisition. As a condition of the 2013 Acquisition, the Company is obligated to pay additional cash consideration to certain equity holders since the Company realized taxable income for the year ended December 31, 2022. The maximum contingent cash consideration payable of $8.0 million is due on or before November 15, 2023. Accordingly, at March 31, 2023, the additional cash consideration was classified as a Level 1 liability. As a condition of the FourQ Acquisition that occurred on January 26, 2022, the Company agreed to pay additional cash consideration if FourQ realized certain firm-specific targets, including the amount and timing of new and incremental combined bookings from FourQ and BlackLine, and revenues from a specified FourQ customer over a three-year period subsequent to the acquisition date. The maximum cash consideration to be distributed is $73.2 million. Changes in the significant inputs used in the fair value measurement, specifically a change in new and incremental combined bookings from FourQ and the Company, can significantly impact the fair value of the contingent consideration liability. At March 31, 2023, the fair value of the contingent consideration liability was $36.7 million. Changes in the fair value of contingent consideration are recorded as general and administrative expenses in the unaudited condensed consolidated statements of operations.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date loss, adjusted for discrete items arising in that quarter. The Company’s annual estimated effective tax rate differs from the U.S. federal statutory rate of 21% primarily as a result of state taxes, foreign taxes, and changes in the Company’s valuation allowance for income taxes. For the quarters ended March 31, 2023 and 2022, the Company recorded $0.6 million tax expense and $12.9 million income tax benefit, respectively. The $13.5 million difference between the $0.6 million income tax expense for the quarter ended March 31, 2023, and the $12.9 million income tax benefit for the quarter ended March 31, 2022, resulted primarily from the partial release of $14.0 million of existing valuation allowance recognized during the quarter ended March 31, 2022, along with changes in the mix of profitable jurisdictions. For the quarters ended March 31, 2023 and 2022, for purposes of calculating its income tax attributed to continuing operations, the Company continued to maintain a full valuation allowance on its U.S. federal and state net deferred tax assets as it was more likely than not that those deferred tax assets will not be realized.

Accounting Policies [Abstract]
Use of estimates	Use of estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, primarily those related to determining the stand-alone selling price for separate deliverables in the Company’s subscription revenue arrangements, allowance for doubtful accounts, cancellations and credits, fair value of assets and liabilities assumed in a business combination, recoverability of goodwill and long-lived assets, useful lives associated with long-lived assets and right-of-use assets, income taxes, contingencies, fair value of contingent consideration, fair value of convertible senior notes, redemption value of redeemable non-controlling interest, and the valuation and assumptions underlying stock-based compensation. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances. Actual results could differ from those estimates.
