Is there a way to turn a refund into a credit memo? Or is there a way to turn an over payment on a deposit into a credit memo without have to create an extra fake invoice? The use case is accounting doesn't want to refund overpayments on deposits. They want to turn them into credit memos. They are asking me to create a customization that will create a fake invoice for the amount of overpayment, then create a credit memo off of that.
