Off-the-shelf CRMs work well for standard sales but often don't fit businesses with their own processes: service chains, manufacturers, clinics or logistics. Teams end up juggling spreadsheets and messengers, and owners never see the real picture.
Prostir Lab builds CRM systems around a company's actual processes: clients and deals, inventory, bookings, roles, reports and automation of routine work. We integrate the CRM with telephony, messengers, ERP and banks so all data lives in one place.
