What is Field Service Management (FSM)?
Field service management is software for scheduling, dispatching, and supporting technicians who perform work at customer sites.
Definition
Field service management (FSM) is the set of capabilities used to plan and execute service work performed away from a company's premises, such as installations, maintenance, and repairs at customer locations. It covers work order management, scheduling and dispatching of technicians, route optimization, mobile access for field staff, parts and inventory tracking, and service contract and warranty management. FSM is essential for industries like equipment manufacturing, utilities, HVAC, medical devices, and industrial maintenance, where service revenue and customer satisfaction depend on efficient field operations. When integrated with ERP and CRM, FSM links service activity to inventory, billing, customer history, and asset records. Many ERP suites with strong service or asset management capabilities include or integrate FSM to support the full service lifecycle.
How Field Service Management Works in ERP
In an ERP context, a service request or work order is created, the system schedules and dispatches the right technician with the needed skills and parts, and a mobile app gives the technician job details, customer history, and the ability to record labor and parts used. Completed jobs flow into billing and update inventory and asset records in the ERP. Integration with CRM and asset or service contract data ensures technicians arrive informed and that service is invoiced correctly.
