Everything is very simple and clear; anyone, even without experience as a cashier, can figure out the interface. Technical support responds promptly and through various channels, we even asked questions on VK! It’s perfect for small retail businesses. You just need to add products, accept payments, and issue receipts. We have the MSPOS cash register, and everything works great; there have been almost no failures in the last six months. After updates, there were sometimes errors, but we contact technical support, and they quickly help resolve the issue. We recommend it!
