# Usage-Based Billing Accuracy Check

## Inputs
A fixed-version usage export, meter aggregation definition, invoice quantities and approved rounding rules.

## Workflow
1. Record the billing period and aggregation rule before summing.
2. Compare billable event totals with invoiced units.
3. Show the unit and amount difference using only the supplied price.
4. Return evidence for billing review without editing invoices.

## Output contract
Meter | period | expected units | invoiced units | unit difference | amount difference

## Fictional acceptance test
Fictional period: approved usage is 2400 units; invoice has 2250 units at 0.20 each. Report 150 missing units and a 30.00 difference, subject to billing review.

## Review gates
Deduplicate events and confirm late-event cutoffs before reporting a discrepancy. Do not treat estimates as charges owed.
