THE REALITY

Brex is brilliant at what it does. Useless at everything else your data needs to touch.

Brex's native adaptors cover the basics but reaching ERP, treasury + non-Brex travel tools means custom integration. Cash forecasting lags because business-banking events arrive in batch. AI projects on spend + cash data hit Brex's per-business rate ceilings.

The integration tool you've already tried probably can't fix it.

What Zapier + iPaaS reach

SaaS-to-SaaS. Useful, until it isn't.

Connectors for Brex, Slack + a thousand other SaaS apps. Cheap + fast for the easy half of integration. Where they hit a wall:

ERP that should see Brex card + ACH spend against open POs + budgets
Accounting platforms beyond Brex's native QBO/NetSuite adaptors
Treasury + cash forecasting needing live business-banking + ACH event flow
Travel management tools outside Brex Travel
Data warehouses + AI agents needing live cash + spend position for forecasting

What Rayven reaches

Cards, banking, ERP, AP + AI. One platform.

The integration platform built for what other tools can't (or won't) reach - plus an AI data fabric, MCP server + app builder layered on top. Australian-priced.

Brex + every ERP, accounting + AP system
Banking, ERP, cards, OCR + custom-built connectors.
Files, legacy SQL, FTP + custom-built connectors
Real-time bidirectional sync, tier-aware + rate-limit-safe
AI Data Fabric, MCP, automation + custom apps included

WHAT YOU CAN BUILD

Brex + Rayven: AI, automation + tools that reach every system you run.

ERP + budgets → Brex

Budget + PO context drives card controls

BEYOND INTEGRATION

Integration is the start with Rayven.

Rayven isn't just a Brex connector. It's the operational software platform underneath - so once Brex is connected, four more capabilities come online by default.

AI-ready data layer (AI Data Fabric)

Brex data joined with ERP, IoT + legacy - contextualised, unified + structured so AI models, agents + tools can use it without ETL prep work.
Learn more →

Live AI access (Rayven MCP)

Claude, ChatGPT + Gemini get live, governed access to Brex + every other connected system. Your AI stops guessing - cites real Brex records + numbers.
Learn more →

Automation + AI agents

Workflows + AI agents act on Brex data without human intervention - escalate at-risk accounts, trigger operational work, auto-update forecasts, draft customer comms.
Learn more →

Custom apps + portals

Unified customer portals, ops dashboards, mobile field apps, partner portals - built on top of integrated Brex data. No separate BI tool, no separate dev stack.
Learn more →

All on top of your existing stack. No rip + replace. Brex stays Brex. Rayven works on what you've already built. Specifically tuned for Brex ACH + card event reconciliation + business-banking dual-endpoint orchestration.

What is Brex integration?

Brex integration is the practice of connecting Brex's card + business banking + treasury platform to the rest of your finance stack - ERP, accounting, treasury + AI - so card spend, ACH + banking events flow in real-time. Rayven delivers Brex integration as part of an AI data fabric.

How does Rayven connect Brex to other systems?

Rayven uses Brex's REST API + webhooks via OAuth 2.0 for real-time bidirectional sync. Card transactions, ACH events, business-banking activity + budget-rule triggers all flow as first-class integration events. See the Rayven Platform.

What systems can Rayven connect Brex to?

Rayven connects Brex to 600+ systems including NetSuite ERP, QuickBooks Online, Sage Intacct, treasury + cash-management systems, travel tools + custom AP + budgeting systems.

How long does Brex integration take with Rayven?

Most Brex integrations go live in 2-12 weeks. A single Brex-to-ERP or Brex-to-treasury flow runs in 2-3 weeks; a multi-entity spend + cash fabric with AI policy + budget controls on top runs 6-12 weeks. Choose DIY, done-for-you or hybrid delivery.

Does Brex have a native API? Why does Rayven add value on top?

Yes - Brex ships a REST API + webhooks with OAuth 2.0. Rayven adds value because production sync needs more than a connector: per-business rate-limit handling, ACH + card transaction reconciliation, beyond-the-native-adaptor ERP coverage + the AI/agent + treasury integration layers on top. Read more in how Rayven works.

What are the most common Brex integration use cases?

Top use cases are card-to-GL posting beyond native adaptors, business-banking-to-treasury flow, budget-driven card controls, AI duplicate-spend detection + AI agents on live cash. See the automations above for specifics.

What are the technical specifics of Brex integration with Rayven?

Rayven uses Brex's REST API + webhooks via OAuth 2.0 for real-time bidirectional sync. Per-business rate limits managed natively via batching, queuing + back-pressure so end-of-day settlement bursts never throttle out. Card transactions, ACH events, business-banking activity, cash sweeps, vendor-master records, custom fields + budget-rule data are preserved with field-level mapping into NetSuite ERP, Sage Intacct, QuickBooks Online, treasury + AI targets - including ERPs beyond Brex's native adaptors. ACH + card events arrive on separate endpoints; Rayven orchestrates a dual-endpoint reconciliation so cash + spend stay in lockstep. Business-banking webhook delivery patterns are normalised against the card webhook stream. Live ERP budget burn + open POs flow back into Brex as card-policy rules so spend ceilings track the budget. Multi-entity Brex estates reconcile via Rayven's spend-master layer. Validated against Brex Essentials, Premium + Enterprise tiers + Brex Business Banking. Configurable to your local tax + compliance environment.
