To stop "PAST_DUE" / "UNPAID" invoice from being processed again, the invoice can be written-off using the written-off API endpoint. This will set the invoice status to "WRITTEN_OFF". Ezypay will stop all ability to modify, retry and update the invoice once the invoice has been written-off.

NOTE: When an invoice is written off via this API, any uncollected customer-paid fees (failed payment fees, load fees, transaction fees) are either waived or reallocated to the merchant and deducted at settlement, depending on the merchant's fee configuration.
