An HVAC company dispatches 24 technicians through a paper-based system. We replaced it with a mobile app in 12 weeks.
The client had 24 field technicians working off paper work orders, phoning in job completion, and getting their schedules in a morning whiteboard meeting. Dispatch was a person on the phone. We built a field service mobile app that replaced the paper and the phone calls. 12 weeks.
24 field technicians running on paper work orders, phone dispatch, and a morning whiteboard meeting that required everyone to be at the office
The client ran a residential and light commercial HVAC business with 24 technicians. The daily workflow: technicians came to the office at 7am for the morning meeting where the dispatcher ran through the day's jobs on a whiteboard. Technicians picked up paper work orders. They completed jobs, got customer signatures on paper, and phoned or texted the dispatcher to report completion and move to the next job. Paper work orders came back to the office at the end of the day (or not — lost work orders were a regular problem) for billing.
The bottlenecks: billing was delayed 2–3 days because work orders had to be physically returned and transcribed. Technicians who needed to see their next job assignment had to call dispatch — there was no self-service schedule view. Customer communication (arrival time estimates, job completion notifications) happened by dispatcher phone call, consuming dispatcher capacity.

The app was built in React Native with Expo for both iOS and Android. Technicians can use their personal devices or company-issued devices — either platform is supported.
Work order data is cached locally on the device. Technicians can complete work orders, capture photos, and collect signatures without connectivity. Data syncs when coverage is restored.
