I'm not sure if I understand your problem. I have the impression that
you just need a flag into your users table to mark if they have been
charged or not. And then based on the value of that flag decide if you
charge them or not when they sign in again. But that logic is evident so
maybe I didn't get your point, your explanation was not so clear, to me
at least.
