Since 2016, our group of companies has been collaborating with Tensor SBIS, and during this time, they have proven themselves positively. They have a modern and convenient service for accounting and reporting to government agencies. Their electronic document management works better than that of other companies, which significantly simplifies work processes. Tensor is a stable and actively developing organization; since 2016, we have had a personal manager through whom all our business processes are handled. We address all issues and connect products exclusively through him. Huge thanks for the work that makes the already complex job of an accountant easier. I express my gratitude to the entire SBIS team for their daily efforts!
