Basis of Presentation, Significant Accounting Policies, and Recently-Issued Accounting Pronouncements	6 Months Ended
	Jun. 30, 2026
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, 2025, which was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2026. 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 unaudited condensed consolidated financial statements. The unaudited condensed consolidated balance sheet at December 31, 2025 was derived from audited financial statements, but does not include all disclosures required by GAAP. The operating results for the quarter and six months ended June 30, 2026 are not necessarily indicative of the results expected for the full year ending December 31, 2026. 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 the 1.00% Convertible Senior Notes due in 2029 (the “2029 Notes” or “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 at June 30, 2026 and through the date of this report. The accounting matters assessed included, but were not limited to, the 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 unaudited condensed consolidated financial statements for the quarter and six months ended June 30, 2026, the Company’s future assessment of these accounting matters 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 - Basis of Presentation, Significant Accounting Policies, and Recently-Issued Accounting Pronouncements” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. There have been no material changes to the Company’s significant accounting policies during the six months ended June 30, 2026. Recently-adopted accounting pronouncements In July 2025, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which the Company adopted during the quarter ended March 31, 2026. The adoption did not have a material impact on the Company's condensed consolidated financial statements. Recently-issued accounting pronouncements not yet adopted In September 2025, the FASB issued ASU No. 2025-06, Intangible - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 removes all references to prescriptive and sequential software development stages. ASU 2025-06 requires entities to begin capitalizing software costs when management authorizes and commits to funding the software project, and it is probable that the project will be completed and the software will be used for its intended purpose. For public business entities, ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-06 on its consolidated financial statements and related disclosures. The Company does not intend to early adopt. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), and in January 2025, the FASB issued Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date ("ASU 2025-01").

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2026
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 income, adjusted for discrete items arising in that quarter. The Company’s annual estimated effective tax rate differed from the U.S. federal statutory rate of 21% primarily as a result of non- deductible officer compensation, stock-based compensation shortfalls, foreign taxes, changes in the Company’s valuation allowance for income taxes, and a one-time tax benefit associated with the base erosion and anti-abuse tax. For the quarters ended June 30, 2026 and 2025, the Company recorded $3.5 million and $6.2 million in income tax expense, respectively. For the six months ended June 30, 2026 and 2025, the Company recorded $9.4 million and $10.8 million in income tax expense, respectively. The decrease in income tax expense for the quarter and six months ended June 30, 2026, compared to the quarter and six months ended June 30, 2025, resulted primarily from a one-time tax benefit associated with the base erosion and anti-abuse tax recognized in the current quarter, along with changes in the mix of profitable jurisdictions.

- Definition

The entire disclosure for income tax.

Segment Reporting [Abstract]

Segment Information

Management has concluded that the Company has one operating and reportable segment. The Company provides subscription and support services that consist of a cloud-based platform that drives digital finance transformation and also provides professional services that consist of implementation and consulting services. The technology used in the subscription and support services is based on a single software platform that is deployed to and implemented by customers. The Company manages the business activities on a consolidated basis, and operating segments have not been aggregated. The accounting policies for the operating segment are consistent with those discussed in “Note 2 - Basis of Presentation, Significant Accounting Policies, and Recently-Issued Accounting Pronouncements” in the Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The Company’s Chief Operating Decision Maker (“CODM”) assesses performance for the operating segment and decides how to allocate resources based on the review of net income. The CODM uses net income, among other measures, for budgeting and resource allocation purposes. Expenses significant to the segment were determined to be cost of revenues, sales and marketing expenses, research and development expenses, general and administrative expenses, interest expense, and the provision for (benefit from) income taxes, all of which are presented in the unaudited condensed consolidated statements of operations for the quarters and six months ended June 30, 2026 and 2025. During the quarter and six months ended June 30, 2026, other significant expenses included depreciation expense of $8.6 million and $17.0 million, respectively, as well as amortization expense of $3.8 million and $7.6 million, respectively. During the quarter and six months ended June 30, 2025, other significant expenses included depreciation expense of $8.0 million and $15.9 million, respectively, as well as amortization expense of $3.5 million and $7.1 million, respectively.

The Company’s intra-entity sales are eliminated upon consolidation. The Company disaggregates its revenue from contracts with customers by geographic location, as it believes it best depicts how the nature, amount, timing, and uncertainty of its revenues and cash flows are affected by economic factors.

The following table sets forth the Company’s revenues by geographic region (in thousands):


	Quarter Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025
United States	$	126,426	$	119,258	$	250,798	$	235,628
International	61,396		52,767		120,179		103,328
	$	187,822	$	172,025	$	370,977	$	338,956

For the quarter ended June 30, 2026, the United Kingdom (U.K.) represented 10% of total revenues. For the six months ended June 30, 2026, no countries outside the United States (“U.S.”) represented 10% or more of total revenues.

The measure of segment assets is reported in the unaudited condensed consolidated balance sheets as total consolidated assets. The following table sets forth the Company’s long-lived assets, which consist of property and equipment, net, and lease right-of-use assets by geographic region (in thousands):


	June 30, 2026		December 31, 2025
United States	$	12,833	$	14,467
International	23,746		21,544
	$	36,579	$	36,011

Net Income per Share

Earnings Per Share [Abstract]

Net Income per Share

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share amounts):


	Quarter Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025
Basic net income per share
Numerator:
Net income attributable to BlackLine, Inc.	$	16,481	$	8,292	$	24,607	$	14,347
Denominator:
Weighted average shares	58,529		62,143		58,981		62,481
Basic net income per share attributable to BlackLine, Inc.	$	0.28	$	0.13	$	0.42	$	0.23

Diluted net income per share
Numerator:
Net income attributable to BlackLine, Inc.	$	16,481	$	8,292	$	24,607	$	14,347
Interest expense, net of taxes	1,710		130		2,751		255


Net income attributable to BlackLine, Inc. for diluted calculation	$	18,191	$	8,422	$	27,358	$	14,602
Denominator:
Weighted average shares	58,529		62,143		58,981		62,481
Dilutive effect of securities	171		476		353		554
Dilutive effect of convertible senior notes	9,858		1,385		9,858		1,385
Shares used to calculate diluted net income per share	68,558		64,004		69,192		64,420
Diluted net income per share attributable to BlackLine, Inc.	$	0.27	$	0.13	$	0.40	$	0.23

The Company computes basic earnings per share attributable to BlackLine, Inc. using the weighted average number of common shares outstanding. The Company computes diluted earnings per share attributable to BlackLine, Inc. using the weighted average number of common shares outstanding plus the effect of potentially dilutive shares, which is based on the weighted-average shares of common stock underlying stock options and unvested stock awards using the treasury stock method, and the effect of the convertible senior notes using the if-converted method.

The weighted average impact of potentially dilutive securities that were excluded from the diluted per share calculations because they were anti-dilutive were as follows (in thousands):


	Quarter Ended June 30,		Six Months Ended June 30,
	2026	2025	2026	2025
Stock options - service-only vesting conditions	587	382	569	429

Restricted stock units - service-only vesting conditions	4,584	1,618	3,527	1,581
Restricted stock units - performance and service conditions	244	141	162	89
Restricted stock units - market and service conditions	647	375	518	285

Contingently returnable common shares	221	—	221	—
Total shares excluded from net income per share	6,283	2,516	4,997	2,384

The denominator for diluted net income per share attributable to BlackLine, Inc. does not include any effect from the Capped Calls as this effect would be anti-dilutive. In the event of conversion of the 2029 Notes, shares delivered to the Company under the Capped Calls would offset the dilutive effect of the shares that the Company would issue under the Notes. Refer to “Note 8 - Convertible Senior Notes” for additional information on the Notes and the related Capped Calls.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation—From time to time, the Company may become subject to legal proceedings, claims, and litigation arising in the ordinary course of business. The Company is not currently a party to any legal proceedings, nor is it aware of any pending or threatened litigation that would have a material adverse effect on the Company’s business, operating results, cash flows, or financial condition should such litigation be resolved unfavorably. Indemnification—In the ordinary course of business, the Company may provide indemnification of varying scope and terms to customers, vendors, investors, directors, and officers with respect to certain matters, including, but not limited to, losses arising out of its breach of such agreements, services to be provided by the Company, or from intellectual property infringement claims made by third parties. These indemnification provisions may survive termination of the underlying agreement and the maximum potential amount of future payments the Company could be required to make under these indemnification provisions may not be subject to maximum loss clauses. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is indeterminable. The Company has never paid a material claim, nor has it been sued in connection with these indemnification arrangements. At June 30, 2026 and December 31, 2025, the Company has not accrued a liability for these indemnification arrangements because the likelihood of incurring a payment obligation, if any, in connection with these indemnification arrangements was not probable or reasonably estimable. Operating Leases — At June 30, 2026, the Company committed $25.0 million for a lease signed but not yet commenced. This lease, which is expected to commence within the next twelve months, has a lease term of 15.5 years

Debt Disclosure [Abstract]

Convertible Senior Notes

2029 Notes

At June 30, 2026, the Company had $675.0 million aggregate principal amount of the 1.00% 2029 Notes outstanding. The 2029 Notes consisted of the following (in thousands):


	June 30, 2026		December 31, 2025
Liability:
Principal	$	675,000	$	675,000
Unamortized debt issuance costs	(7,681)		(8,954)
Net carrying amount	$	667,319	$	666,046

The effective interest rate of the 2029 Notes, excluding the conversion option, remained 1.40% at June 30, 2026.

The Company carries the 2029 Notes at face value less unamortized debt issuance costs in the unaudited condensed consolidated balance sheets and presents the fair value for disclosure purposes only. The estimated fair value was determined based on the actual bids and offers of the 2029 Notes in an over-the-counter market on the last trading day of the period. The estimated fair value of the 2029 Notes, based on a market approach at June 30, 2026, was approximately $623.0 million, which represents a Level 2 valuation.

During the quarter ended June 30, 2026, the Company recognized $0.6 million of interest expense related to the amortization of debt issuance costs and $1.7 million of coupon interest expense. During the quarter ended June 30, 2025, the Company recognized $0.6 million of interest expense related to the amortization of debt issuance costs and $1.7 million of coupon interest expense.

During the six months ended June 30, 2026, the Company recognized $1.3 million of interest expense related to the amortization of debt issuance costs and $3.4 million of coupon interest expense. During the six months ended June 30, 2025, the Company recognized $1.3 million of interest expense related to the amortization of debt issuance costs and $3.4 million of coupon interest expense.

The 2029 Notes were not convertible at June 30, 2026. It is the Company’s current intent to settle conversions of the 2029 Notes through “combination settlement”, which involves repayment of the principal portion in cash and any excess of the conversion value over the principal amount in shares, cash, or a combination for any further value.

In connection with the offering of the 2029 Notes, the Company entered into privately-negotiated capped call transactions (the “2029 Capped Calls” and together with the 2026 Capped Calls (as defined below), the “Capped Calls”). There have been no changes to the condition of the 2029 Notes since December 31, 2025, and the 2029 Capped Calls were unchanged and still outstanding at June 30, 2026.

2026 Notes

On March 15, 2026, the scheduled maturity date of the 0.00% 2026 Notes (the “2026 Notes”), the Company repaid the total outstanding $230.2 million aggregate principal amount pursuant to the terms of the 2026 Notes with cash on hand.

During the quarters ended June 30, 2026 and 2025, the Company recognized no interest expense and $0.2 million interest expense related to the amortization of debt issuance costs, respectively.

During the six months ended June 30, 2026 and 2025, the Company recognized interest expense related to the amortization of debt issuance costs of $0.2 million and $0.4 million, respectively.

Redeemable Non-Controlling Interest

6 Months Ended

Jun. 30, 2026

Equity Method Investments and Joint Ventures [Abstract]

Redeemable Non-Controlling Interest

The Company operates in Japan through BlackLine K.K., in which it holds a 53% controlling interest. The non-controlling interests are held by Japanese Cloud Computing, M30 LLC, and Masamune Mimura (the “Investors”). 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 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 Company classified the marketable debt securities as available-for-sale debt securities at the time of purchase and reevaluated such classification at each balance sheet date. The valuation techniques used to measure the fair values of 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.

Foreign currency forward contracts are classified within the Level 2 value hierarchy, as the valuation inputs are not actively traded, and the valuation inputs are based on quoted market prices for similar instruments, including currency spot and forward rates.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Basis of Presentation, Significant Accounting Policies, and Recently-Issued Accounting Pronouncements (Policies)	6 Months Ended
	Jun. 30, 2026
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 the 1.00% Convertible Senior Notes due in 2029 (the “2029 Notes” or “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 at June 30, 2026 and through the date of this report. The accounting matters assessed included, but were not limited to, the 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 unaudited condensed consolidated financial statements for the quarter and six months ended June 30, 2026, the Company’s future assessment of these accounting matters and other factors could result in material impacts to the Company’s consolidated financial statements in future reporting periods.
Recently-adopted accounting pronouncements and Recently-issued accounting pronouncements not yet adopted	Recently-adopted accounting pronouncements In July 2025, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which the Company adopted during the quarter ended March 31, 2026. The adoption did not have a material impact on the Company's condensed consolidated financial statements. Recently-issued accounting pronouncements not yet adopted In September 2025, the FASB issued ASU No. 2025-06, Intangible - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 removes all references to prescriptive and sequential software development stages. ASU 2025-06 requires entities to begin capitalizing software costs when management authorizes and commits to funding the software project, and it is probable that the project will be completed and the software will be used for its intended purpose. For public business entities, ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-06 on its consolidated financial statements and related disclosures. The Company does not intend to early adopt. In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), and in January 2025, the FASB issued Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date ("ASU 2025-01"). ASU 2024-03 requires public companies to disclose, in interim and reporting periods, additional information about certain expenses in the financial statements. For public business entities, ASU 2024-03, as clarified by ASU 2025-01, is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company is currently evaluating the impact that the standard will have on the disclosures within its consolidated financial statements. The Company does not intend to early adopt.
Derivative Instruments	Derivative Instruments The Company uses foreign currency forward contracts with an approximate maturity of one month to mitigate foreign currency exchange rate fluctuations on certain foreign currency-denominated monetary assets. Under ASC 815, Derivatives and Hedging, these contracts are not designated as hedging instruments. The fair value of the forward contracts, estimated based on prevailing exchange rates of the various hedged currencies at the end of the period, is reported as either prepaid expenses and other current assets or accrued expenses and other current liabilities in the unaudited condensed consolidated balance sheets. At June 30, 2026, the total gross notional amount of forward contracts was $51.0 million. Refer to “Note 7 - Fair Value Measurements” for additional information on the fair value classification of the forward contracts. For the quarter and six months ended June 30, 2026, the net gains from the forward contracts were $0.5 million and $1.4 million, respectively, which were recorded in general and administrative expenses. For the quarter and six months ended June 30, 2025, the net loss from the forward contracts, which was recorded in general and administrative expenses, was $1.4 million. Cash flows from the settlement of the forward contracts are classified as operating activities in the unaudited condensed statements of cash flows.

- Definition

Disclosure of accounting policy for its derivative instruments and hedging activities.
