Question: What causes the Error Processing Payment message on a voided payment on an owners account?
When a payment is returned as Error Processing payment, it means that the payment (ACH or eCheck) was unable to be processed or sent to the bank due to some invalid information on the payment. This invalid information primarily lies within the bank account number or routing number that was entered for the payment being incorrect, so in most cases you should have the user re-enter their information and attempt to process the payment again.
This can also happen for merged owners, if updating the payment method on their accounts for ACH draft and using the "Update All Linked Accounts?" button. If you use this function, you must ensure that the ACH draft information is fully re-entered as if it is being entered for the first time to use that button. If you just simply go to one account with the information already entered and then just click the update all linked accounts button, it will copy only the last 4 of the routing and account number to the linked accounts and then cause this void payment error on those accounts because the full information was not copied. Just be sure to enter the information fully and click that button so it can copy over the full information.
