Design
The data model decisions.
Three choices shape a trade contractor's design. The first is how customers and sites relate: a property manager or facilities department may control many buildings, so accounts, locations and billing contacts need to be distinct records. The second is the asset register: which equipment is tracked individually, such as chillers, panels, risers or elevators, and which is treated as a consumable. The third is how work is classified, with work types for repair, planned maintenance, inspection, installation and quoted work, each carrying default durations and required skills. Get these right and scheduling, contract coverage and reporting all read from one consistent structure.
Accounting systemCompleted work orders, labor and parts pass to invoicing, and payment status comes back so technicians know about past-due accounts before they arrive on site.
Inventory or ERPWarehouse stock, purchase orders and part costs stay in the system of record, while van-level quantities and consumption on each job sync with Field Service.
Building automation and monitoringAlarms from connected equipment can open a work order automatically, handing the technician fault codes and readings before anyone drives to the building.
