Field Service App

Technicians drove back to office to check parts availability and update job status.

Overview

We built an offline-first mobile app that gives field technicians everything they need on the road — job details, parts availability, optimized routes, and customer communication — eliminating unnecessary trips back to the office.

The Challenge

HVAC technicians drove significant distances daily but frequently returned to the office to check parts availability, get job details, or submit completed work orders. Productivity was low, customers received poor communication about arrival times, and the company was losing billable hours to unnecessary driving.

Our Approach

1

Built an offline-first app that stores job data locally and syncs when connectivity is available

2

Integrated with parts inventory so technicians can check availability and reserve parts from the field

3

Implemented route optimization for daily schedules that accounts for traffic and appointment windows

4

Added customer communication with automatic ETA updates and completion notifications with photos

My techs were driving back to the shop to check if we had a part in stock. That's an hour wasted on a good day. Now they check from the truck, reserve the part, and go straight to the next job. We're billing more hours without adding headcount.
