I compared the rates of different companies offering acquiring services for quite a while. Overall, they all seem similar, and I didn't notice any significant differences. In the end, I chose T-bank. I was attracted by their responsive support, which is ready to help until the very end. During a year of using their acquiring service, there was a situation when the terminal couldn't connect to the internet. The problem was solved remotely by switching the mode from Wi-Fi/SIM card to just the SIM card, and it worked. This happened on a holiday, yet there was still an employee available who clearly explained what to do.
