Brex has introduced an AI-native accounting application programming interface (API) aimed at automating accounting workflows and enabling real-time connectivity with enterprise resource planning (ERP) platforms and other financial software.

The company said the API is built to automate accounting workflows from end to end and support continuous, two-way data exchange between Brex and ERPs, instead of relying on traditional, one-way bank feeds.

This two-way connection is intended to allow finance teams to capture required information at the time a transaction is made and send it into their ERP in real time.

Brex noted that key accounting fields can also flow from ERPs back into its platform so that spending rules and business context are applied when transactions occur, with the goal of reducing manual work and speeding up period-end close.

The API includes real-time webhooks and additional endpoints that alert connected accounting systems as soon as new activity happens. This removes the need for batch processing and manual updates.

The company added that, when used with its accounting AI features and automation tools, the API can support processes from transaction coding through to export preparation and closing the books.

Brex chief technology officer James Reggio said: “With accounting, accuracy and speed can’t be trade-offs.

“Our AI-native accounting API brings intelligent automation and real-time, enriched data to finance teams and their ERP partners, executing work like coding transactions and preparing exports on their behalf so they can close the books faster with confidence.”

The accounting API will initially be available through integrations with Rillet and Campfire, which Brex described as AI-native ERP platforms.

Rillet founder and CEO Nicolas Kopp said: “The manual month-end close is a relic. At Rillet, we believe in the zero-day close.

“By pairing Brex’s real-time data with Rillet’s automation engine, your ledger is always current from prepaids to accruals to multi-entity consolidation. Your finance team can start acting on audit-ready financials in real time.”
