FSM (field service management) software and CMMS (computerized maintenance management system) software are both used to manage field service operations, but they have different focuses:
Compared to CMMS, FSM software is more customer-focused, provides a greater range of features, and assists with several field service tasks like tracking equipment and assets, tracking and assigning work, and scheduling and assigning work etc.
CMMS software focuses more on maintenance and helps businesses with various operational processes and internal maintenance like collecting data about asset performance, maintenance activities and costs etc.
