How to make a payment to two accounts at once?

Question

Payment systems

Good afternoon, we encountered such a problem, we have a website where there is a subscription fee of 250 rubles.
It is necessary to implement payment in 3 stages:
1) Our services are a certain amount that comes to our account
2) The amount that comes to the account of the operator, it is to the number of this SIM card that is linked to the account (corporate tariff)
3) The amount that a hosting partner comes for providing us with certain services, but the amount is for a specific account, so that it does not happen that Vasya paid, and Petya turned everything on
Imagine 10,000 users and the manual work that needs to be done to identify those who paid and debtors.
How to do everything in automatic mode, a person presses the payment button, and the money goes immediately to 3 organizations?

Answer 1

money to one common account, then scatter from it to other accounts, through the same payment gateways

Answer 2

Question.
Do you notify the payer that the funds will be "shared" between the operator, hosting and your service?
If yes, do you indicate how much to whom will be paid?
