Making Changes to a Purchase Payment: Editing, Unposting, Unallocating, Unreconciling & Deleting a Purchase Payment
Updated 31 October 2026
A posted Purchase Payment can’t be edited. If it’s wrong, for example the wrong amount, date or bank account, unpost it and delete it, then record it again correctly.
The basic rule: undo things in reverse order
To change a posted payment, undo whatever has happened to it since, newest first, then make your change:
- If it has been reconciled, unreconcile it from the bank account’s Bank Feeds tab. See Unreconcile Matched to Payment.
- Unpost it. Aedon makes equal and opposite ledger entries, and the payment goes back to Draft.
- Correct it and post it again, or Delete it.
Remove a Purchase Payment
- If the payment has a failure against it, remove the failure first. See Making Changes to a Purchase Failure.
- If the Reconciled Status is Reconciled, unreconcile it from the bank account’s Bank Feeds tab.
- Open the payment from the Purchase Payments tab, or from the invoice’s Payment & Audit History tab.
- Click Unpost(2). The status changes to Draft.
- Click Delete(2) and confirm.

Once the payment is deleted, the invoice’s Balance Outstanding goes back up by the amount of the payment, ready for you to record the correct payment.
When it can’t be changed
- Included in a submitted VAT return: it can’t be unposted or deleted. Correct it with a new transaction in a later VAT period.
- Dated before the lock date: it can’t be unposted until your finance controller moves the lock date back.
Every change is recorded in the audit history and the ledger entries, so you always keep a full audit trail. If you still can’t make the change you need, please raise a case and we’ll help.
