What to provide

The draft invoice, the metered usage export, the pricing tiers and the billing period.

Workflow

  1. List usage line items on the draft invoice.
  2. Recompute each charge from the usage export and the tier rates.
  3. Flag lines where the charge deviates from the recomputed amount.
  4. Return the check without editing the invoice.

Output contract

Line | usage qty | tier rate | expected | invoiced | flag | reviewer

Fictional acceptance test

Fictional invoice: 6 usage lines; 5 recompute correctly and 1 charges 41,000 metered events at the wrong tier, overbilling by 3,700. Flag 1 line.

Review gates and limits

Re-check the tier table in effect for the billing period. Corrections are proposed for review, never applied by this check.
