The operational core: a unified, web-based platform for dispatch, scheduling, and fulfillment, with role-based views for operations staff, sales representatives, and technicians. All roles work from the same live record; when a job's status changes, every connected view updates in real time. At the center is a purpose-built matching engine. Given a job's location, time window, and required skills, it returns qualified technicians ranked by actual driving distance — not straight-line or postal-code approximation — in under 50 milliseconds, as measured in testing. Scheduling conflicts are prevented structurally: the database itself rejects a double-booked assignment, so the failure mode is engineered out rather than caught afterward. Job offers are sent to matched technicians by SMS; the first qualified acceptance claims the job.
