Good day, lorraine10,
You can open the customer profile and check if you made a duplicate payment. Then, delete the sales receipt to ensure you only have one payment record in QuickBooks
Let me show you how:
- Select Sales from the left-hand menu, then choose Customers.
- Click the customer name to open the profile.
- Go to the Transaction List tab.
- Locate the sales receipt.
- Click the arrow next to Print, then choose Delete.
