I recently had a family who had been set up under one account, but the parents wanted a split account. The tuition had already been entered for our billing months (July - April). However, NO payments had been made.
I was able to create a "split" account for the father, and add the tuition as a half fee. But when trying to change it on the mother's end, I 1) couldn't remove any fees from July (since the month had passed, even though there were NO payments made). I also 2) couldn't completely zero out the tutition, without there being a $1000 amount that was billed and then subtracted in the July month.
I know that would look very unprofessional and confusing to my parents. I think it is crazy that I had to chat support to get these changes made, and couldn't do them on my own even though I am an admin. We need more power to change billing errors like this.
