Let agents run your Brex spend management

QX issues cards, monitors transactions, chases missing receipts and flags policy breaks—so finance teams stop reconciling and start steering the business.

@QX Any spend I should be worried about this week?
QX
Marketing is 23% over budget on paid ads, and three transactions over $5k are missing receipts—including a $12k AWS charge from Tuesday. Want me to ping the cardholders?

Stop chasing receipts, reconciling transactions, and policing budgets line by line. Hand it to an agent.

Receipts

Receipts collected automatically

QX spots every transaction missing a receipt or memo, pings the cardholder where they work, and follows up until it's filed—so month-end close stops being a manual chase.

Controls

Cards issued in seconds

Onboard a new hire, spin up a vendor card, or tighten a limit on the fly. The agent provisions the card, sets the right controls, and routes it to the right person.

Oversight

Budgets that watch themselves

Every transaction gets categorised, matched against policy, and checked against the budget. Anomalies, overspend and unusual vendors surface the moment they happen—not at quarter-end.
