Invoices

Issue a credit note against an invoice

Raised an invoice by mistake? Issue a numbered credit note against it. The invoice is voided, the balance owed drops to zero, and your books are corrected with a clean reversing entry. Only unpaid invoices can be credited this way.

Updated August 2026

A credit note is the correct, auditable way to reverse an invoice you should not have raised. It creates a proper numbered document (CRN-000001, CRN-000002 and so on), voids the invoice it credits, and drops the balance owed to zero. Everything is copied from the invoice by the system, so the reversal matches the original charge to the fils.

Before you start

A credit note can only be raised against an invoice that is issued, still unpaid, and not already credited. If the invoice has been paid, a credit note is not the right tool, because that would leave the client's money unaccounted for. See Cancel, credit note or refund: which one to use if you are not sure which applies.

Open the credit notes page

From the accounts menu under Your Accounts, click Credit notes to open the credit note page.

  1. Log in to your workspace.
  2. In the left menu, under Finance, click Your Accounts.
  3. In the accounts menu, click Credit notes.

The page has an Issue a credit note panel at the top and a list of every credit note below it.

Issue the credit note

The Issue a credit note panel with the Invoice to credit dropdown and the Reason box.

  1. In the Issue a credit note panel, open the Invoice to credit dropdown. Only eligible invoices (issued, unpaid and not yet credited) appear here.
  2. Choose the invoice. Each option shows its number, the client and the amount.
  3. In the Reason box, type why you are crediting it, for example Service cancelled before delivery. This reason is printed on the credit note.
  4. Click Issue credit note.

A green confirmation appears at the top, telling you the credit note number and that the invoice it credits has been voided.

What happens next

  • A numbered credit note document is created, with its own downloadable PDF.
  • The invoice it credits is marked Cancelled, so the balance owed becomes zero.
  • The credited invoice drops out of your revenue, receivables and VAT figures, exactly as a cancelled invoice would.
  • Your books get a matching reversing entry, so they still balance.

You can open any credit note from the list to see its details or download its PDF.

If your invoice is not in the list

If the invoice you want is missing from the Invoice to credit dropdown, one of these is usually the reason:
