Field service management (FSM) is the software category for businesses that send workers to customer locations — lawn care, HVAC, plumbing, pest control, cleaning, electrical, and similar trades. FSM software typically bundles four core functions: scheduling, dispatch, invoicing, and customer management.
The category includes a spectrum from generic platforms (ServiceTitan, Jobber, Housecall Pro) that try to serve all trades, to vertical-specific tools (Grassr for lawn care, Aspire for commercial landscape, FieldEdge for HVAC) that pick one industry and build for it deeply.
The tradeoff is feature breadth vs workflow fit. Generic FSM platforms have more features but require configuration to fit any one trade. Vertical FSM platforms have fewer features but they all fit the workflow out of the box. For solo operators and small lawn care crews, a focused vertical FSM can be easier to adopt than a broader generic platform.
The FSM category has been growing fast for a decade as residential service businesses move off paper schedules, spreadsheets, and QuickBooks invoicing. The shift to mobile-first interfaces and card-on-file billing in the last 5 years has dramatically lowered the operational burden of running a service business.
