“The usage-to-invoice mapping worksheet from Module 3 caught a duplicate gateway fee we had been absorbing for two quarters.” — Minseo P., revenue controller, Busan

Three habits that keep API billing reviews defensible
We emphasize reproducible steps your colleagues can re-run next period—not one-off spreadsheet heroics.
-
Anchor every variance to a metering source
Learn to label request IDs, usage windows, and price-book versions so a variance cannot float without an owner.
-
Separate timing gaps from true overcharges
Cutoff policies, delayed webhook delivery, and prepaid drawdowns look similar until you chart them against settlement calendars.
-
Package evidence for people who were not in the room
Build binders that walk an external reviewer from invoice line to log excerpt without requiring a live demo.
