Let's say I want to encourage my customers to reinvest their refund from a return into other products from my company, so I offer them the option to get their refund as store credit or to apply it directly to an exchange order. When I create the RMA, one option I have is to put a non-inventory line item that represents the store credit or exchange amount that I'm withholding from their refund. (I'll show it on the Sales Order as a Customer Deposit.) I'm curious if this is the best way to represent this on the RMA from an Accounting standpoint, or if I should use a whole separate record (like a Credit Memo) against the RMA instead of a line item to offset the amount of refund owed to the customer upon receipt of the returned items.
