Q: Is there a way to provide credit to a customer for a return so you can give a discount on the items on a new purchase?
A: Invoices and Credit Memos are only created when you connect POS to QuickBooks Financial software (QBFS) and use the account payment type. So if you do connect the two, create your refund transaction. This will give the customer credit that can be used to discount another transaction by using the account payment type for the credit. Then the customer only needs to pay the difference.
