When this guide is useful
A vendor credits a prior business purchase after the original expense was recorded.
The distinction that matters
Trace the credit to the original transaction and period. A later refund should not disappear into miscellaneous revenue without a documented accounting decision.
A worked situation to investigate
A practice receives a credit for defective supplies that were purchased and expensed in an earlier accounting period.
The example is illustrative. Begin with the underlying event and its source documents, then separate missing facts from disagreements about their treatment. Work through the checks below in the order that matches your file, rather than treating a completed checklist as a tax conclusion.
Build a traceable handoff
Identify the affected person, entity or property and the relevant period. Keep original evidence, corrections and the reviewer's written conclusion connected. If the facts change after review, preserve the earlier version and ask whether the change affects implementation.
