Schedule AND edit!
If you're offering an option to schedule payment in advance, you should also enable editing the amount!!!
I like to schedule all my payments in advance to pay on their due dates. But you're expecting me to pay the ENTIRE balance if I do that!!! That's unreasonable and unfair.
The company that did the work and arranged the financing confirmed with me AHEAD OF my signing that I would pay monthly installments of a specified amount.
But then they sent me an invoice for the WHOLE balance! While that may be their doing and not Intuit's, it seems to me it may be your doing to restrict advance scheduling of payments less than the full balance. I find that inconvenient, ignorant, and inconsiderate. It ignores my needs and actually makes it HARDER for me to pay on time!!!!! PLEASE FIX THAT!!!
