Acceptance of payments in the Web service abroad, what payment systems and what are the pitfalls?

Question

Business Informatics

If the company is located in the Russian Federation, but aims to work with the whole world, for example, some online service. How to arrange payment for this service is the same for any person who has a credit card or an electronic account in electronic money other than bitcoin.
For example, ROBOKASSA helps us with this, and as for non-residents of the Russian Federation, for example, the USA or Germany, how can they pay for the service?

Answer 1

I am from Germany and will tell you how convenient it is to pay me for online services.
PayPal.
Why?
Transfer every second, for me as a "buyer" without any% for the transfer.
You can link at least your bank card or visa / mastercard. Or even pay with a visa without having a login there.
And I know that if something went wrong, I can get my money back.
