BlackLine makes cloud-based software for corporate finance and accounting teams, focused on automating the financial close process — the labor-intensive work that happens between recording transactions in an ERP and publishing financial statements. Every quarter and year-end, accounting teams must reconcile accounts, match transactions, prepare journal entries, manage intercompany transactions, and consolidate results. BlackLine replaces the spreadsheets traditionally used for this work with automated, auditable workflows. BlackLine's core product suite, Record-to-Report, covers account reconciliations, transaction matching, journal entries, task management, consolidation, and intercompany management. A newer and growing suite, Invoice-to-Cash, covers cash application, collections, credit and risk management, and electronic invoicing, helping companies collect cash faster and reduce DSO. BlackLine sells on a SaaS subscription model, with subscription revenue accounting for over 90% of total revenue. BlackLine is transitioning from per-seat pricing to a platform model based on company size — revenue, legal entities, ERP count, and transaction volume — which decouples revenue growth from user count. BlackLine sells primarily to mid-size and large enterprises, with particular focus on complex multinationals, and relies heavily on a partner ecosystem including SAP, Accenture, Deloitte, EY, and KPMG to drive deals. SAP is BlackLine's most important go-to-market partner, with SAP customers accounting for roughly 26% of BlackLine's revenue. In late 2025, BlackLine launched Verity, a suite of AI agents embedded throughout its platform for reconciliation automation, collections, and accruals.
