What is account reconciliation software?

Software that standardizes, controls, and automates matching account balances to supporting detail during the close. BlackLine replaces spreadsheets with one governed workspace where matching, certification, and preparation are automated and Verity™ AI handles the rest.

How accurate is BlackLine's transaction matching?

Over 99% matching accuracy on billions of transactions. High-volume, high-complexity matching runs automatically, so only exceptions reach a person.

Can AI prepare reconciliations without breaking SOX controls?

Yes. Every AI action is rule-validated, human-approved where required, and logged to an immutable audit trail. Governed by ISO 42001. Segregation of duties is enforced automatically, so the same person can never prepare and approve a reconciliation; and the full record of who did what, and when, satisfies SOX Section 404's requirement for a documented internal control structure. The rules themselves, whether for zero balance accounts, general ledger to subledger tie-outs, amortization schedules, or other reconciliation types, are transparent and available for auditors to review directly, alongside the reconciliations they produce.

Does BlackLine reconciliation work across multiple ERPs?

Yes. BlackLine is ERP-agnostic and unifies data from any ERP, subledger, and bank into one governed reconciliation workspace. Out-of-the-box connectors cover SAP, Oracle, NetSuite, Workday, Microsoft Dynamics, and more than 30 ERPs and source systems. With SAP specifically, the relationship goes deeper: BlackLine is the only SAP Solution Extension partner in the record-to-report space, including financial close and intercompany, premium-qualified by SAP itself. Actually, SAP even runs its own reconciliations on BlackLine.

Why reconciliation burns out finance teams

Reconciliation is where the close grinds to a halt. Teams spend weeks on low-risk tick-and-tie work and wrestle VLOOKUPs to match millions of transactions — eroding capacity, risking material error, and pushing skilled accountants toward the exit.

Millions of lines, by hand

Brute-force matching across disconnected systems and spreadsheets doesn't scale with transaction volume.

Material error hides in the noise

Manual prep and sample-based review leave high-risk items undiscovered until an auditor finds them.

Your best people, on the lowest work

Senior accountants spend the close certifying low-risk balances instead of investigating real exposure.

How BlackLine Delivers

BlackLine replaces brute-force matching with intelligent, rules-based automation. By reconciling millions of transactions in minutes and surfacing high-risk anomalies, we free your accountants to focus on strategic analysis rather than spreadsheet wrangling.

How BlackLine automates account reconciliation

On a single governed foundation, market-leading matching and auto-certification do the volume, and agentic AI prepares entire reconciliations on its own.
