If you make a credit note with wrong details or by mistake, you can void or delete it. Voiding the credit note removes its values but keeps it in your accounts for future reference.

 NOTE: To void or edit saved credit notes, you need full access to the Expenses option. If you have restricted access, you can only edit or delete draft credit notes.

Editing or voiding a reconciled stand-alone credit note

 NOTE: If you’ve refunded the credit note, unallocate the refund before editing or voiding it. For more information, see "To edit or void a reconciled allocated credit note" below.

1. From Expenses, click Vendor Credit Notes.
2. Click the credit note you want to edit.
3. Edit the details and click Save. The new values appear in your accounts.

Deleting a vendor credit note

1. From Expenses, click Vendor Credit Notes.
2. Select the check box next to the relevant credit note.
3. Click Delete (on the toolbar at the top of the list).
4. Click Yes. The values no longer appear in your accounts.

Editing or voiding a reconciled or allocated credit note

 NOTE: When you allocate a credit note to an invoice or create a credit note from within an invoice, you create a customer transaction. Remove the transaction before editing or voiding the credit note.

1. Click Contacts.
2. Click the required contact.
3. In the Activity area, click the relevant customer transaction
    NOTE: The transaction date is the date you allocated the invoice and credit note.
4. Clear the check boxes for the invoice and the credit note you want to unallocate. NOTE: If you allocated multiple transactions at the same time and only want to unallocate one invoice and credit note, the remaining transactions are unaffected. If the credit note covered multiple invoices, click the credit note, edit the amount to pay, and then click Save. For example, if the invoice was for $50 and the credit note was $100, the amount to pay will be -$50. 
5. Click Save. The invoice and credit note are now outstanding.
