Agree what the snapshot means
Select the suppliers, currency groups and as-of date before extracting data. Record whether each date is an approval date, document date or posting date. A credit issued on the last day but posted in the next month can create a timing difference. Keep that explanation visible rather than changing dates to make totals match.
Bring forward open cases
A review of this month’s returns alone can miss credits approved earlier. Carry forward unresolved returns and unapplied credit balances. Keep a stable case reference so a continuing issue is not counted as a new finding each month. A case closed after the reporting cutoff belongs in the subsequent update, not retrospectively in the earlier snapshot.
Test completeness before chasing documents
Ask the source owner to confirm that approved returns, credit notes and applications cover the same agreed population. Reconcile source row counts or control totals where available, by currency. Sample some settled cases as well as exceptions. A report containing no credits may mean there were none, but it may also be the wrong export filter.
Assign the next action
Purchasing or the supplier owner checks whether the expected credit value was agreed and issued. Finance checks posting, allocation and applications. Warehouse colleagues provide return references and dispatch evidence. Give each exception a named owner and a next-review date. The example routine below is an internal working method, not a legal or supplier payment deadline.
Carry evidence into the next month
Close a case only when a specific document or explained adjustment resolves it. Keep the previous calculation, the explanation and the source reference. Review preparation time and the share of false positives to decide whether the control is worth repeating. Do not label all open amounts as savings or add unlike currencies into a headline number.
Suggested handoff, adapt to your team
| Check | Owner | Completion evidence |
|---|---|---|
| Scope and cutoff | Finance lead | Agreed supplier list and date |
| Approved amount | Supplier owner | Approval reference |
| Credit issued | Supplier owner / AP | Credit-note reference |
| Application | AP | Allocation or settlement record |
| Case closure | Review owner | Explanation and source link |
Your action checklist
- Set one as-of date.
- Include opening items.
- Confirm completeness of all three sources.
- Separate missing, partial and unapplied amounts.
- Assign owners and keep the evidence.
Practical questions
Should every open item be closed by month end?
No. A valid timing difference can remain open with an explanation and a next review date.
Can the month-end checklist post adjustments?
No. It supports review; authorized finance staff decide on accounting entries.
