Good morning to you too, @BigRog!
You're on the right track in applying the $75 payment to the invoice. No need to create a credit memo since the excess amount will be available as credit.
What we need to do now is to deposit the invoice payment to your business account. This way, the deposit will correspond to your account. Let me show you how.
- Go to the Banking menu in your QuickBooks Desktop (QBDT) for Mac.
- Select Record Merchant Service Deposits.
- Click the Add payments to record tab.
- Select the small arrow icon next to the first deposit on the list.
- Review the payments in QuickBooks.
- Compare the deposit total in QuickBooks with the deposit for that day on your bank statement.
- When everything matches, select Save and close.
- Then click Record deposit when you've added all the payments in QuickBooks to a bank deposit.
You can also see the Manually record bank deposits for QuickBooks Payments section in this article for more details: Automatically record QuickBooks Payments bank deposits in QuickBooks Desktop.
Furthermore, I highly recommend working with your accountant for additional advice. This way, we can ensure your accounts are well accounted for.
In regards to stopping the bank payment charge, I'd suggest contacting our merchant support team for further guidance. They'll be able to pull up your account in a secure space and guide you through this process.
In addition, I'm attaching this link that serves as your guide in effectively matching your accounts: Reconcile an account in QuickBooks Desktop.
