Thanks for reaching out to the Community, RonG-Fresno.
To verify my understanding, when processing these transactions, are you doing them with the Receive payment or e-invoicing features inside of QuickBooks Online? If so, your payment records will automatically appear in the customer's profile. In the event they're processed inside of your Merchant Service Center, they'll have to be manually entered into QuickBooks.
Once I have more details about how you're processing these transactions, I'll be able to conduct further research if necessary.
I'll be looking forward to hearing back from you. Have an awesome day!
