One schema, every cloud.

UFMS keys are designed to round-trip cleanly through every major cloud and through the FOCUS billing spec. Pick your target, copy the snippet, paste it into your IaC. The right values land in the right places.

FOCUS v1.0

FinOps Open Cost and Usage Specification. The standard billing schema published by the FinOps Foundation. UFMS keys map onto FOCUS columns at the row level.

Editor's noteFOCUS columns use PascalCase. Tag dictionary entries inside FOCUS keep their original case from the cloud provider.
