Audit evidence for API billing reconciliation
A focused hub on binders, samples, and retention—aligned with how we teach the craft at API Connect HQ.
What “good evidence” means here
For API charges, evidence is re-performable: another competent reviewer can start from your index, open the same digests, and arrive at the same variance conclusions without a live walkthrough. Screenshots alone rarely meet that bar.
Core artifacts
- Invoice and price-book excerpts for the exact period
- Usage-to-invoice map with version stamps
- Cutoff calendar stating timezones
- Sample index with file digests
- Exception log and residual-risk acceptance
-
Define scope
Name vendors, products, and the billing window before collecting files.
-
Collect once, label twice
Every file gets a human label and a digest recorded in the index.
-
Test, then narrate
Run the map and samples; write short narratives only for residual items.
-
Handoff
Sign the binder and schedule the next period’s owner while context is fresh.

Put the methods into a cohort
Reading helps; practicing on a live invoice cycle embeds the habit.
