✅ What the AI can do
- Query transactions, card expenses and reimbursements by date, merchant, employee, department, compliance status or spend limit.
- View spend limits and remaining balances; in Claude, edit memos, receipts, attendees and spend limits on your own transactions.
- Connect Brex to Claude for automating your company's finances. Finance monitors compliance and runs powerful queries. Employees get personalized memo guidance, policy answers, and status updates. Permission-based access ensures admin oversight while streamlining management.
⛔ What it can't do / limits
- Can't approve or reject expenses, create reimbursements, or change your team's transactions; use the Brex dashboard or mobile app for those.
Plans & requirements
- An admin must do a one-time setup before employees can use Brex in Claude or ChatGPT.
- Creating or updating purchasing and employee cards is admin-only.
