Which service provides a link to pay?

Question

Payment systems

What service makes it possible to simply get a payment link to give it to the client and he paid in any way (qiwi, Yandex, visa card, mastercard, and mobile operators), and I was able to withdraw this money from the service to the card. (NOT BILLING). So that the link to the payment hangs somewhere (in the product description) and the client pays and then writes to me what he paid, so that I do not invoice with a specific amount, but he enters it himself (the price of the goods)!
