First, sorry for my english. The problem is complex, I will try to explain it the best I can. We are trying to use Tryton + GNU Health for a clinic. The clinic has a kind of subscription/insurance where you paid an amount per month and you get an amount of services to use (for example, 3 medical consultation free...). So should be able to know the amount of this products/services uses by a person in the last month, and the price will depend on this.
To make things more complicated, the subscription can be per family too, i.e., if your son uses the total of medical consultation that you had free, you will have to pay. I tried to use price_list but I don't understand how it works. Anyway, I think you can’t consider the historic with that.
