Billing schedule
A billing schedule is the sequence of invoices a contract generates, timing, amounts and triggers, derived from contract shape rather than chosen at invoicing time.
The schedule is where contract terms become cash. Annual prepaid, quarterly in advance, monthly in arrears and milestone-triggered produce identical ARR and entirely different working capital. The schedule must therefore be derivable from the contract record, not reconstructed by a person reading the agreement each cycle.
Schedules drift from contracts through amendments. A mid-term upgrade, a co-terminated add-on or a partial credit each change the sequence, and where the change is applied in the billing system but not the contract record, the two diverge permanently. Reconciling them is the control.
Where it breaks
Amendments are applied to invoices without updating the contract record, so deferred revenue requires a manual plug every period.

Commercial commitment, invoicing, recognition, and collection answer different questions. Reconcile the clocks without treating them as one metric.
