Why are my paid invoices and then when I deposit them are double counted?

You can use the Receive payment feature instead of bank deposit to record the customer's invoice payment, waynecad.

The receive payment option will mark the invoice as paid and match them. I'll gladly make the process easy for you. 

Here's how:

1. Click the + New button and select Receive payment.
2. Pick the customer under the Customer dropdown.
3. Choose the Payment method and the Deposit to dropdowns.
4. In the Outstanding Transactions section, select the checkbox for the invoice you're recording the payment for.
5. Click Save and close.

I'm also sharing a link to learn when to record or use the Bank deposit feature in QBO for guidance: Record and make bank deposits in QuickBooks Online.

In addition, check out these resources about sending statements to customers and invoice reminders about their dues:
