Records and measurement boundaries
Retain the original service entry, reversal and replacement records, approval history, invoice match result and payment status. Request the reason for reversal and the scope of service actually accepted. Capture event timestamps so the reviewer can distinguish the state at payment approval from the state visible in a current export.
Checks that resolve this question
Trace the original entry to any replacement before declaring acceptance missing. Check whether quantity, service period, cost center or scope changed. Recalculate the supported invoice portion only after the service owner confirms the final acceptance. Review credits and rebills together to prevent a corrected entry from creating a second payment or a duplicate discrepancy.
The finance and operations decision
AP should return an event timeline and a payment disposition approved by the service owner and finance. An unresolved acceptance question can be routed through the organization's payment policy; a supported billing adjustment needs supplier acknowledgment. Keep the original match and the corrected evidence so the control decision remains explainable.
Limits of the conclusion
This guide does not instruct AP to withhold payment automatically. A reversed entry is evidence of a change, not proof that no service occurred or that the supplier owes a refund.
