My invoice has expired or been canceled, but the payment has already been sent. Should I get a refund?

If the invoice is paid after it was canceled or expired, you’ll be presented with a refund form on the invoice window shortly. 

If payment was paid in full, you can mark the ‘Accept Payment’ checkbox on the refund form and we will make every attempt to process this payment, however, it may not be possible and a refund may be required.
