How about adding a simple refund like a cash register has.
- Hit refund
- enter amount to refund
- pick category/item
- hit continue and the cash draw opens.

At least this way the customer gets a cash refund and the sales numbers are somewhat correct.

Agreed! What good is a POS system that can’t perform all of the necessary functions of a POS system? This is a thing I had to do today and after 5 minutes of not being able to figure out how to give a partial refund for one item or even a cash refund, I finally gave up, opened the cash drawer manually and gave the guy the refund. Now I have to figure out how to account for that so that my drawer still balances. Also, my store sells products for many other vendors, consignment style, so I also have to figure out how to account for that refund coming from the correct vendor…what a mess!

We need a the be able to refund any amount needed for cash or credit card!!!!! I dont want to REFUND THE ENTIRE PAYMENT!!!
