What Brex does

Brex is a corporate card and spend management platform for startups and mid-market companies. Its AI features auto-suggest GL coding, flag anomalous or out-of-policy transactions, and power dynamic approval chains and travel rule enforcement. It's used for card issuance, bill pay, reimbursements, and multi-entity expense management rather than as a standalone AI bookkeeping tool.

What you get: AI-suggested GL coding, Anomaly/compliance detection, Dynamic approval chains, Multi-entity expense management, Bill pay and reimbursements, Travel booking with policy rules, Live budget tracking.

Typical jobs: issue corporate cards with automatic expense coding; enforce travel and spend policy across entities; flag out-of-policy or anomalous transactions automatically; consolidate bill pay and reimbursements for a scaling startup.

Worth knowing: Advanced AI compliance and multi-entity features require the paid Premium tier; Enterprise pricing is not published.

What users complain about: One reviewer described a 1-star experience where account closure did not automatically disable the linked card, resulting in a $108 unauthorized charge with an unresponsive fraud-dispute process; others noted Brex 'only supports a USD account and doesn't accept check payments.'
