System for non-cash payments between clients for the site?

Question

Payment systems

The situation is this.
There is a site on the Internet that allows people who provide paid services to meet people who need these services. That is, the service acts as a kind of intermediary, a kind of ali-express or Uber . The
question is how to organize non-cash payment on the site between clients, taking into account the fact that the service must take a commission for each successfully rendered service.
In which direction do you rush? There are a lot of services that allow you to organize payments like "online store site - buyer" (Yandex.Checkout, Robokassa, etc.), when the site itself is the recipient of the payment, but I don't quite understand how to use this for p2p payment relationships like " seller - site commission as an intermediary - buyer". What are the options for this?

Answer 1

Otherwise - payment of tax on all receipts.

Well, not everything is so gloomy)
For example, an individual entrepreneur with SNO 15% (Income-Expense) - will give "all receipts minus all payments minus maintenance costs" * 15%
, that is, if you open the brackets, you get 15% of the service commission minus the rest expenses.
well, yes ... the commission can regularly be equal to the rest of the expenses with all the resulting mathematics)

Answer 2

What you want to implement is called "Financial Intermediation", which in legal terms is an extremely dreary task. About three years ago I researched this moment for one of the projects. Very briefly - you either need to open a bank yourself, or be in a very, very test relationship with the chairman of the board of some bank. I didn’t have either, so we, in the end, abandoned a similar undertaking.
