How to refund a Quick Sale for customer credit

Note: Because a 'Quick Sale' does not have a specified customer assigned to it, a customer needs to be assigned to the sale before it can be refunded as customer credit. To do this view the following knowledgebase article first: 07. How to change customers on a sale

Once the sale has a customer assigned to it, you can then go about refunding that sale as customer credit. To do this, first find and select the sale via 'Sales Menu'/'Find Sale'. Click 'Refund Sale' at the bottom of the screen. On the refund screen, check the items being refunded. In the 'Refund Payment' section, select the payment type as 'Customer Credit'. Click 'Pay'. Click 'Finish Sale'.
