Start with the evidence
List the period, relevant accounts, document sources and expected output. Separate preparation work from the decisions that require the responsible reviewer’s approval.
Work through the example
A September review covers two operating accounts and the September invoice list. An unrelated annual project is outside that scope unless someone explicitly adds it to the task.
Make the next step clear
Save the scope with the checklist and record later changes. If a source is excluded, say why so the next person does not mistake a limited review for a complete one.
Keep the source context
Keep the review period, source set and unresolved questions explicit. A checklist records work performed; it does not by itself establish that financial statements are complete or compliant. Use the appropriate reviewer for decisions about accounting treatment.
