Hello Oobsailing:waving_hand:.Thanks for contacting the Community about voiding the transaction. You would usually only use refund receipt usually if the original transaction was a sales receipt. If however, the original transaction was a customer invoice that was marked as paid there would be a number of steps to follow(which we can go through) to both do a credit note and a separate transaction of an expense to record the change in debtors and the fact you returned the money. Generally, if they have paid and then cancelled and you have refunded him you could do the above. Just reply back and we can give more information on that. If however, you want to just void the invoice you can go to the customer itself and on the right-hand side if you click on the drop-down arrow by action there is a void option which will void the invoice.
