What Is FSM?
Field Service Management is the management of field operations including dispatching technicians, managing work orders, tracking mobile workforce, and delivering on-site services. FSM platforms coordinate the entire lifecycle of field work from customer request through scheduling, dispatch, execution, and invoicing.
FSM systems handle work order management – the creation, assignment, tracking, and completion of service tasks performed at customer locations. They provide intelligent dispatch and scheduling that matches technicians to jobs based on skills, availability, location, and priority. FSM platforms include mobile workforce apps with offline capability so technicians can access job details, capture data, and collect signatures even without connectivity.
Beyond dispatch, FSM encompasses route optimization (minimizing drive time across multiple jobs), parts and inventory management (truck stock, warehouse parts, replenishment), digital proof of service (customer signatures, photos, timestamps), SLA tracking (response time, resolution time, first-time fix rate), and field invoicing (generate invoices on-site or automatically upon job completion). The goal is to maximize technician utilization, reduce travel time, improve first-time fix rates, ensure SLA compliance, and deliver a professional customer experience.
