Question

Payment systems

Are there such payment aggregators so that I do not need to open accounts in all payment systems? Let's say that on the site the client had the opportunity to pay in 10 ways, and all this fell on one account for me, which one I choose - card, poison, WM. That is, in fact, the aggregator should perform the function of an exchanger.
Well, an important point, so that you can use it as an individual.
I have no experience with them. I poked myself into Interkassa, and there it began - the certificate in WM must be at least personal, in the poison must be identified. How the hell is happiness? ))
