# Billing Threshold Invoice Trigger Check

Check whether accrued usage crossed the billing threshold that should trigger an invoice.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
The billing threshold amount, the accrued usage, and the invoices issued in the period.

## Workflow
1. Record the billing threshold amount.
2. Sum accrued usage in the period.
3. Compare the accrued total to the threshold.
4. Return the check without billing changes.

## Output contract
subscription | threshold_amount | accrued_usage | threshold_reached | invoice_expected | invoice_found

## Fictional acceptance test
Fictional subscription carries a 500.00 threshold and accrued usage of 620.00, 120.00 over the line: an invoice should exist for the period and the ledger shows none.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
