Do you want to cancel a plan before the minimal term but unsure what will happen with outstanding amounts owing?
If you would like to cancel a customers plan before the end date, you can do this very easily. (You can see how to do that here: https://help.payleadr.com/knowledge/how-do-i-cancel-a-plan)
If you cancel a plan mid term and they still have payments remaining these payments will be left unpaid with no body owing any payments. If you cancel a contract this will be seen as the contract being fulfilled and any outstanding amounts are written off. This includes any dishonoured payments, any failed payment fees and any future payments that where due.
