We searched for a suitable multifunctional CRM system for our sales department for a long time and ultimately settled on Prosty Biznes. This system fully meets our requirements, as we were looking for a multifunctional solution. We have been using it for six months, and no one has expressed any dissatisfaction. There is a free plan available for small businesses, and we chose the Pro plan, which costs 1900 rubles per month. The functionality of the system is impressive: it includes document flow, client database management, a task manager, as well as free internal calls, convenient reports, and much more. We highly recommend this CRM and deeply regret that we didn't start using it sooner!
