void credit note
delete credit note
The option to Delete/Void a Credit Note can be used to remove wrongly generated Credit Notes. If the Void option is used, the status is marked as Voided but the Credit Note will still be available in the system. It is good accounting practice to void an invoice instead of deleting one.
To Delete/void a Credit Note, select the credit note from the Credit Notes page and click the Void/Delete this credit note.
Note: You can Delete/Void Refund Due credit note only. Refunded credit note and Adjusted credit note cannot be voided
