Which payment system to choose for an online trading platform?

Question

Payment systems

Good day to all. We have a very difficult situation. We have developed an Internet trading platform (alaza.ru) in which various goods and services are sold from different suppliers (legal entities, individual entrepreneurs, etc.).
Those. some kind of legal the company sends an application for partnership with us and, after approval, receives the functionality of an online store (places its goods and services there). For this he pays us a certain amount per month.
But the money for the goods that he sells completely takes himself. The catch is that traditional payment systems only register one checking account per domain name. Therefore, it becomes difficult to transfer to partners their money for the goods sold. We would not want the money that was transferred from the buyer to the seller (partner) as our income. After all, in fact, this is not our income.
Please advise, maybe somewhere there is some kind of payment system that allows you to withdraw money to different current accounts.
Or maybe there is some kind of legal way out of the situation to show this money as not our income, but simply transit money.

Answer 1

The only legal way is to receive money for yourself, to conclude agency agreements with partners, to carry out accounting of income and expenses in full.

Answer 2

Visual Studio, the most convenient
