Hello again, pecoairdispatch.
Thank you for proactively getting back to us here in the Community. Allow me to join the thread and help provide information about the customer payments in QuickBooks Desktop.
The process you do in our program should mirror how you deal with these situations in the actual. Since the transaction from Service Titan credits the outstanding invoice, you have the option to refund the customer's QuickBooks payment.
For the detailed steps and important reminders on creating refunds, I recommend visiting the article I'm adding on this:
Void or refund credit card payments in QuickBooks Desktop.
Just in case you need additional guidance, please know you can also reach out to one of our Merchant Service support.
Please be sure to let me know if there's anything else I can do to help you with the process. Thanks for dropping in and take care.
