Overview


Brex covers the issuing side of payments: corporate cards, spend controls, expense management, and bill pay, with an API for programmatic card creation. Brex became part of Capital One in April 2026.

Underwriting is based on company cash balances rather than personal guarantees. Cards carry per-employee and per-category limits, receipts are captured against transactions, and spend data syncs to NetSuite, QuickBooks, and Xero. The product is US-focused.

Common use cases


  • Issue corporate cards with per-employee spend limits
  • Automate expense capture and categorisation
  • Pay vendor bills from a single approval workflow
  • Sync spend data into NetSuite or QuickBooks

Key Features


  • Corporate cards with spend limits and real-time controls
  • Expense management with receipt capture and categorization
  • Bill pay and vendor payment automation
  • Multi-entity spend management for portfolio companies
  • ERP integrations with NetSuite, QuickBooks, and Xero
  • Programmable spend policies and approval workflows
