# Brex Brings AI-Native Accounting Automation to ERPs Brex's AI-native Accounting API automates workflows end-to-end and enables deeper integrations with ERP systems and other key integration partners. **URL Source:** https://www.brex.com/journal/press/brex-launches-ai-native-accounting-api --- **SAN FRANCISCO, January 21, 2026** — Brex, the intelligent finance platform, today announced a new AI-native Accounting API designed to automate accounting workflows end-to-end and enable deeper, real-time integrations with enterprise resource planning (ERP) systems and other key integration partners. Brex’s Accounting API goes beyond traditional bank-feed integrations by enabling two-way data flow between Brex and ERPs. This enables teams to harness Brex’s rich transaction data, capturing the information they need upfront and pushing it to their ERP in real time. The result is end-to-end accounting automation, improved accuracy, and a faster month-end close. The Accounting API will first launch with [Rillet](https://www.rillet.com/) and [Campfire](http://campfire.ai), two of the leading AI-native ERPs. Today, most finance teams still rely on batch exports, CSV uploads, and manual reconciliation to manage accounting workflows. These processes introduce delays, missing context, and errors that compound at month-end, making it difficult for finance leaders to trust their data or operate strategically. Brex’s AI-native Accounting API is built to remove these gaps by keeping accounting data continuously synchronized and automatically executing accounting work as transactions happen, rather than waiting until the close, no matter what ERP the company is closing their books in. “With accounting, accuracy and speed can’t be trade-offs,” said James Reggio, CTO of Brex. “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 Brex Accounting API unlocks: - **Two-way data sync** to capture all accounting data finance teams need upfront, and nothing they don't. Key accounting fields flow from ERPs into Brex so all policy is enforced with business context captured at the point of transaction. - **Real-time webhooks and expanded endpoints** that notify accounting systems the moment transactions happen, eliminating batch processing and manual updates. - **Deep integration with Brex's Accounting AI** workflows and automations, allowing finance teams to automate the entire accounting process, from swipe to close. "The manual month-end close is a relic,” said Rillet's founder and CEO Nicolas Kopp. “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." "As we continue to support more rapidly growing and public companies, our integration with Brex represents the future they need: rich transaction data flowing in real time, with zero manual reconciliation," said John Glasgow, founder and CEO at Campfire. "Every finance team can have enterprise-grade power without the complexity." In addition to the Accounting API, Brex also recently introduced new AI-driven accounting capabilities designed to further eliminate manual work and reduce errors: - **Accounting Workflows:** New Brex workflows can automatically prepare and send expenses to ERPs without human intervention. In just the first few months, customers have already eliminated 10,000+ hours of manual work. - **AI-Driven Expense Coding**: Brex AI continuously learns and suggests the best value for every field employees have to fill in. In addition, Brex AI identifies patterns and suggests rules and mappings for perfect accuracy and control in auto-coding expenses. - **ERP Validation Rules:** Brex can now automatically understand data constraints coded within ERP systems and enforce them within Brex to ensure expenses are coded correctly from the start. Together, these capabilities help finance teams maintain audit-ready data at all times and turn month-end close into a predictable, continuous process. ## Related Articles ### [Brex and Tekion Partner to Bring Embedded Spend Management to the Modern Auto Dealership ](https://www.brex.com/journal/press/brex-for-tekion-spend) Brex is the first fully embedded corporate card and spend management solution that delivers a native spend management experience designed for automotive dealer groups. ### [Brex Helps Power OpenAI Global Spend and Financial Operations](https://www.brex.com/journal/press/brex-helps-power-open-ai-global-spend-and-financial-operations) OpenAI is using Brex to help run their global spend and financial operations. ### [Brex x FTB](https://www.brex.com/journal/press/brex-announces-partnership-with-fifth-third-bank) Intelligent finance for the businesses that power America: Brex and Fifth Third Bank unite to deliver AI-native corporate cards and automation at unprecedented scale. ### [Brex Announces Partnership with Oracle as First Fintech Global Issuer to Power B2B Payments in Oracle Fusion Cloud ERP](https://www.brex.com/journal/press/brex-announces-partnership-with-oracle-fusion) Powering the future of enterprise payments: Brex is the first fintech embedded in Oracle Cloud ERP, enabling global companies to pay suppliers instantly and intelligently. ### [Brex Announces Launch of Stablecoin Payments](https://www.brex.com/journal/press/brex-announces-launch-of-stablecoin-payments) Powering the next generation of business: Brex will be the first global corporate card to offer instant balance payments with stablecoins, helping customers operate globally with speed. ### [Brex Partners with DoorDash for Business to Deliver DashPass to Brex Corporate Cardholders](https://www.brex.com/journal/press/brex-partners-with-door-dash-for-business) A new way to fuel productivity: Brex partners with DoorDash for Business to bring DashPass perks and rewards to Brex corporate cardholders.
