Thanks for getting back, Ben.

The steps earlier are for QuickBooks Online. Here are the steps for QuickBooks Desktop:

1. Go to Reports at the top menu, and select Customers & Receivables.

2. Choose Transaction List by Customer.

3. Click the Customize Report button, and go to the Filter tab.

4. Search for Transaction Type, and select Invoice.

5. Search for Paid Status, and select Closed.

6. Click the OK button.

Let me know how this goes. Thanks!
