Transactions -

Thanks for reaching out to the Community, Felix02. I'm here to provide details on receiving customers' overpayments. 

You can record an overpayment by creating a credit note and issuing a refund check. It will enable you to match the amount you paid to the customer's account and balance the negative amount.

To start, here's how:

1. Go to the Customers menu.
2. Navigate to Create Credit Notes/Refunds.
3. Choose a customer on the Customer: Job drop-down.
4. Enter the items you're giving credit for.
5. Save & Close.
6. Select Give a refund and select OK. 

Kindly follow the steps below to process a refund:

1. The check is filled out automatically. Select OK.
2. Link the check to the overpayment. Go to the Customers menu and then select Receive Payments.
3. From the Received from drop-down, select the Customer.
4. Then, select the Discounts and Credits icon.
5. In the Available Credits section, select the check you created and then Done.
6. You may see a prompt to Confirm transfer, If you do, select Yes. The amount will be applied automatically to the invoice.
7. Select Save & Close.
