About case

Online Casa transforms the way small and medium-sized businesses handle sales and reporting. Through a simple chatbot interface, users can sell goods, issue fiscal receipts via integrated software cash registers (РРО), accept payments by tapping bank cards directly on their smartphones, and manage tax reporting with minimal effort.

The system supports registering cash registers, stores, and trading points with the tax authorities — suitable for both individual entrepreneurs (ФОП) and companies (ТОВ). Online Casa combines fiscal compliance, payment acceptance, inventory management, and reporting into a seamless, mobile-first experience. Go to the project
