The billing threshold amount, the accrued usage, and the invoices issued in the period.
How it works
- Record the billing threshold amount.
- Sum accrued usage in the period.
- Compare the accrued total to the threshold.
- Return the check without billing changes.
The output
subscription | threshold_amount | accrued_usage | threshold_reached | invoice_expected | invoice_found
Worked fictional example
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.
Checks and limits
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.
