"The payment gateway does not appear to be properly set up in the contract" is an error message that can occur when you are utilizing Auto-Pays with ACH accounts.
If you see this message, for the specific patient, remove the ACH source from the autopay information in the patient contract and save. Once that is done, re-add the ACH autopay source and save. This will correctly link the auto-pay source and correct the error.
