A refund after the close: link the periods without rewriting the past
Trace a later refund to a completed commission run, check the original rate and preserve a clear two-period record with a worked AUD example.
A refund received after a commission period is complete creates a new event. The earlier record should still explain the calculation that was closed at the time. Connect the refund to that record, then document its reviewed effect in the later process.
The useful part
Preserve the original completed run and record the refund as a linked later event. Check the original amount, previous refunds and chosen rate before accepting the adjustment.
Keep the earlier calculation intact
Find the completed run containing the original item. Retain the run label, source reference, staff member, category, basis, rate and commission amount. The purpose is to explain what was included then, not to retroactively make the old source file resemble today’s position.
Do not remove the original sale from a completed summary merely because a later refund exists. That can break the handover record and make earlier exports disagree with the changed total. A linked adjustment shows both events and makes the timing understandable.
Trace the same item through two periods
This fictional AUD example uses a supplied exclusive basis. A $100.00 retail sale generated $10.00 commission at 10% in the 12–18 September period. Its full refund is reviewed in the 19–25 September period under the example’s recorded reversal method.
| Period | Other accepted commission | Linked item effect | Period total |
|---|---|---|---|
| 12–18 Sep 2026 | $300.00 | Original retail: +$10.00 | $310.00 |
| 19–25 Sep 2026 | $400.00 | Linked refund: −$10.00 | $390.00 |
| Combined record | $700.00 | $0.00 net item effect | $700.00 |
The first period remains $310.00
The later period explains the −$10.00 event. Together, the records show that the original item’s commission effect has been reversed in this fictional method.
Check the rate instead of assuming today’s rate applies
If the current retail rate is 15%, calculating −$100.00 at that rate gives −$15.00. Reversing the original $10.00 result gives −$10.00. The $5.00 difference is a choice of method, not a rounding issue.
Record which rate and treatment the actual process requires. Do not infer an entitlement or deduction rule from this example. If the intended method uses the original rate, retrieve it from the earlier record; if another method applies, retain the evidence and explanation for that method.
Establish a complete link before review
Keep the refund’s own date and reference. Reusing the original positive sale reference without explaining the later event can make the adjustment look like an accidental duplicate or correction to the old file.
- Locate the original item and completed run, using more than a customer name or amount.
- Match the refund reference to the original item and confirm its signed amount.
- Check prior partial refunds so the cumulative amount is understood.
- Verify the original commission basis, rate and included amount.
- Record the selected later-period treatment and its financial effect.
- Confirm that the refund has not already been included through another export.
Handle missing evidence as an unresolved item
If the original sale is not in available history, do not automatically assume that commission was previously included. It may predate the workspace, belong to another business location, have been excluded, or use a different staff attribution. Request the earlier source and handover record.
Where evidence cannot be recovered immediately, keep the item visibly unresolved with the missing facts listed. A note such as “refund from last month” does not establish the original rate or amount. Avoid importing the original positive sale again merely to create a link, because that can count the old sale a second time.
Keep the calculation model honest
Trimsum can retain completed-run evidence and review a signed refund line in a later draft. Its flat-rate calculation does not automatically join a refund to its historical sale and recover that sale’s rate. A source reference and clear review note remain necessary.
If a historical rate differs from the rate needed for other current-period rows, do not change a whole staff rule simply to make one refund match. Use a verified process that supports the intended calculation, preserve the separate evidence and explain the resulting handover. A commission worksheet does not itself execute recovery or determine what may be deducted.
Put it to work.
Keep the original run, refund reference, selected rate and reviewed effect together.
