What is being tested
Did a revised invoice replace the prior version rather than create an additional payable? The boundary for this investigation is supplier invoice revision versus new liability. Begin with the disputed transaction or population, then identify which original invoice establishes the observed position and which revision notice supports the comparison. A difference in totals should not replace this question.
Evidence: original invoice
For supplier invoice revision versus new liability, original invoice must be linked to revision notice. Keep the issued document version and line-level quantity, currency and service period. A header total cannot establish which component is being tested. Retain later corrections as linked versions, so a replacement does not create a second liability.
Evidence: revision notice
For supplier invoice revision versus new liability, revision notice must be linked to replacement invoice. Preserve the source owner, transaction reference, period and accepted version. Explain which field answers the financial question and which facts still require confirmation. Incomplete supporting records should create a named evidence gap rather than an assumed quantity, price or entitlement.
Evidence: replacement invoice
For supplier invoice revision versus new liability, replacement invoice must be linked to open-item ledger. Keep the issued document version and line-level quantity, currency and service period. A header total cannot establish which component is being tested. Retain later corrections as linked versions, so a replacement does not create a second liability.
Evidence: open-item ledger
For supplier invoice revision versus new liability, open-item ledger must be linked to original invoice. Use the opening position, dated movements and closing position together. Preserve the distinction between requested, authorized and posted changes. The reconciliation should explain how the source item moved through the account, not simply assert that the final total agrees.
Reconciliation logic
Trace the supplier's supersession instruction and compare remaining open balances after replacement. Build the comparison at the level identified by original invoice and retain the governing version from revision notice. Show intermediate classifications and excluded items separately; a net total can hide an unsupported component or a correctly offset correction.
Exception conditions
A supplemental invoice may add scope rather than replace the original. Treat the item as an unresolved exception only when the comparison described here cannot be supported by the linked original invoice, revision notice, replacement invoice, open-item ledger. Document the conflicting input or rule. A plausible operational explanation requires validation, but it should not be discarded to maximize an apparent financial difference.
Human review and outcome
AP confirms the revision authority and posting history. Retain a version-to-liability bridge and prevent double payment. Keep the reviewer's reason and source references with that disposition. A supported correction should be followed to the revised record or settlement; an accepted explanation can close the question with no adjustment. Missing authority or evidence should remain an open task rather than a confirmed recovery.
Limitations and processing boundary
A PO, acceptance record or supplier credit request alone cannot prove a complete recovery. The authoritative supplier, contract, PO, invoice and receipt processor is not complete. Treat commercial interpretation, authorized acceptance and final credit application as separate validation steps. In this scenario, absence of original invoice or revision notice limits whether the comparison can be completed. The review method describes what people should validate, not a promise that AuditRes automatically detects or executes this specific outcome.
