A cloud service that simplifies the registration of transactions in electronic form via the internet. According to Federal Law 54, it is necessary to use online cash registers and send electronic receipts to customers. ATOL offers online cash register rental for 2,900 rubles per month, which is a convenient way to meet legal requirements without having to purchase a cash register. The system generates fiscal documents at the time of transactions and sends them to the OFD. In fact, the rented cash register from ATOL is located in their data center. When a product is paid for, the system creates a receipt and sends it to the customer; the tax service has information about the cash register, so I have no problems. I only give a lower rating because I previously used ATOL's physical cash registers, which I didn't quite like, and also due to the high rental cost. 2,900 rubles per month seems a bit overpriced.
