Making Changes to a Purchase Credit: Editing, Unposting, Unallocating & Deleting a Credit

Updated 31 October 2026

You can correct a Purchase Credit as long as it isn’t locked by a reconciled refund, a submitted VAT return or your lock date. Every change is recorded in the Audit History and the Ledger Entries.

The basic rule: undo things in reverse order

  1. If the credit has been refunded, remove the refund first. See Making Changes to a Purchase Refund.
  2. If it has been allocated to invoices, click Unallocate. This creates no ledger entries; it puts the amount back on the invoices and the credit.
  3. Click Unpost. Aedon makes equal and opposite ledger entries and the credit goes back to Draft.
  4. Correct it and post it again, or delete it.

The Allocation History and Refunds & Audit History tabs show what has been done with the credit, so you know what to undo.

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.

If you still can’t make the change you need, please raise a case and we’ll help.
