Scenario: Customer purchased items with Check or Credit Card and had to return some of the items, the items have to be returned to your inventory and handled properly by Point of Sale so the order should be opened and the items applied with negative quantities.  The negative quantities create a negative dollar total for the item(s), the sales tax amount will also be properly credited and all inventory details will be properly tracked.

NOTE: verify that the Check or Credit Card payment originally used has cleared your account to avoid fraud.

Setup the customer in your customer files so that the accounts receivable refund check can be issued properly.
