Is there a way to create a refund on an invoice? I've noticed that once it's marked paid, the invoice can't be edited....which is great. So I tried creating a new invoice and making an item with a negative balance, and that didn't work, so I tried applying a discount to the amount of the refund and that didn't work.
Is there anyway to refund or credit a user's account? I'm mainly looking at this for my accounting side of things to give my customer a visual of where his money has gone, or refunded and given credit.
