Three hard problems, one API

Checker handles the infrastructure layer that every fintech needs but nobody wants to build twice.

Smart payment routing

Automatically select the lowest-cost, highest-reliability provider for every transaction. Failover to backups in under 100ms when a rail goes down.

Automated reconciliation

Match every incoming and outgoing transaction to your general ledger in real time. Catch mismatches and flag them before month-end.

Compliance automation

Auto-generate MAS transaction reports, FATF screening, and audit trails. Stay ready for regulatory examination at any time.

How a payment flows through Checker

"We had three bank integrations that each reconciled differently. Checker replaced all three with one consistent data model. Our month-end close went from two days to half a day."

Sanjay K., Head of Payments Engineering at a regional marketplace platform, from our early-access program

"The compliance layer was what sold us. We were spending engineer time reading MAS circulars and writing conditional routing logic. Checker abstracts all of that."
