Payment system for a mobile application with payouts?

Question

Mobile development

Hello. We need a system that allows you to replenish the balance of the application and subsequently deposit funds to your bank card.
Applications for real estate agents.
They see an order on the exchange, take it for a 10% commission, which they must transfer to another agent who placed this order.
That is, the system is as follows: he replenishes the balance by 5,000 rubles. They are on his virtual account (and the real money is on our current account or on our card), then he took an application and out of these 5,000 rubles - 500 rubles went to another agent. And this other agent decided to withdraw this money. He enters the LC and presses withdraw .. and then? Should we transfer money to him from the current account? It turns out that we all have to pay tax (although the agent's commission is not our income). Maybe there are services that allow you to keep money on an intermediate account until the moment of withdrawal of funds, or something else like that. Thanks
