There are a lot of steps to remember when creating a school-issued refund. You have to 1) unallocate the payment, 2) go back to the billing detail and zero out the month, 3) apply a fee called "refund"

It would be awesome if you could click something that says "I need to make a refund" and it would ask you if it is a full or partial refund, and then it takes you through the steps.
