Good afternoon, faced such problem, we have a site where there is a monthly fee of $ 250.
You need to realize the payment in 3 stages:
1) Our services is a lump sum which comes to our account
2) the Amount that comes at the expense of the operator, it is the number is the SIM card tied to the account (corporate rate)
3) the Amount of that comes the hosting partner for providing us with certain services, but the amount for definitely account that has not happened so that Bob paid, and Petit all involved
Imagine 10,000 users and manual work that needs to be done to identify paid and debtors.
How to do everything in automatic mode, the person presses the button payment, and the money is going from 3 organizations?
