How do I issue customers credits for returned merchandise?
Simply create an invoice and indicate the quantity as a negative number. For example, if you sold a customer 5 widgets and they return 2, do an invoice for -2 widgets. This will cause the invoice to have a credit balance, which will be subtracted from the customer balance. You will also see the 5 products sold and the two returned on your Sales Report. If you bill your customers using the memo invoice, simply enter a negative amount in the invoice amount to create the credit.
