The online cash register Bifit is an excellent solution for those who want to avoid unnecessary expenses. If you look at the nearest competitors, they offer more features, but they charge a subscription fee that usually starts at 500 rubles per month. There are also options with a free minimal tariff, but all additional features are paid. In this regard, Bifit wins, as it offers more capabilities for free than other services with free tariffs. Another advantage is its excellent compatibility with all models of cash registers. At least, that's what they claim; I have an Atol 30F, and everything works without any issues. So, everything is fine with this model, I can confirm that. In operation, Bifit performs adequately. There was only one incident with duplicate product entries, but that happened a long time ago. The duplicates had a tax rate of 20%, and when I tried to process the receipt, the cash register displayed an error about an unknown tax rate. I had to work a bit to resolve the issue. It turned out that the error was related to technical work on their servers. Since then, similar situations have not occurred. I have been using this system for a long time, and it completely satisfies me.
