Payment system for RussiaAutor: Pavel M.
Currently, there is only one payment system in the constructor, suitable for Russian users, and even then, suitable with a creak. Robokassa has a very unfortunate interface and, moreover, has stopped working with self-employed people (a separate type of taxpayers in Russia with lighter conditions). It would be great if the developers paid attention to the Paymaster payment system and added it to the constructor. This system is more convenient and works with all types of taxpayers.
Adding this system can increase interest in your product in a fairly large market.
