When I started my business four years ago, I carefully scanned the market for online CRM programs. My choice fell on Firmao, because in my opinion their interface was the most intuitive, and the possibility of individual modification of the program made it possible to adjust its functionality to our needs. After 4 years of using Firmao, I am convinced that this software will be an important part of the further development of our company.
