Custom Web Apps for Field Service Teams
In short
Aqib Ops builds field service apps in 6–10 weeks. Each app is offline-capable from the first sprint: mobile-first job management, route optimization, photo capture with EXIF-stripped sync, customer signature capture, and a dispatcher console that updates in realtime as crews work.
The problem
Field service teams operate in cell dead zones, on cracked Android tablets, with crews who don't want to learn a new app. Generic SaaS doesn't survive the parking-lot test, and bespoke quotes from agencies start at $250k.
Our approach
We design for the worst-case device first: offline IndexedDB sync, queued mutations, optimistic UI, file-system access for photos and signatures. The dispatcher console is built in the same codebase but optimized for desktop. Same data model, two surfaces.
Stack we'd reach for
React + Vite PWA
Installable to home screen, runs offline, no app store review.
Postgres + ElectricSQL
Local-first sync that survives 4 hours in a basement crawlspace.
Mapbox + OSRM
Route optimization without the Google Maps tax.
WorkBox + IndexedDB
Battle-tested offline strategies; queued mutations that retry on reconnect.
Twilio for SMS
Crews and customers actually read texts; nobody reads your in-app inbox.
What you'd get
- Offline-first PWA installable on iOS + Android
- Job assignment with route optimization
- Photo + signature capture with auto-sync
- Dispatcher realtime console (web)
- SMS notifications to customers (Twilio)
- QuickBooks / Xero sync for invoicing

A 40-truck HVAC company
Replaced a paper-and-FaceTime workflow with a single PWA. Dispatch overhead dropped 55%; same-day completion rate up 31% in the first quarter.
Frequently asked
Does the app actually work offline?
Yes. Crews can complete an entire day of jobs in a basement with no signal — the app queues all mutations locally, optimistically updates the UI, and syncs when connectivity returns. We test in a Faraday cage.
Can it work on cheap Android tablets?
Yes. We design for $99 Lenovo tablets, not iPad Pros. The app stays under 2MB initial load and renders smoothly on devices with 2GB of RAM.
How much does a custom field service app cost?
Most field service apps we ship land between $30k and $75k depending on route-optimization complexity and accounting integrations. That's a fraction of bespoke quotes that typically run $150k+.
Why a PWA instead of a native app?
PWAs install to the home screen, run offline, push notifications on Android, and don't require app store review. For 90% of field service teams, the user experience is indistinguishable from native — at half the build cost.
Can you integrate with QuickBooks or ServiceTitan?
Yes — QuickBooks Online and Xero out of the box. ServiceTitan is doable but adds 2–3 weeks because their API is less standardized than the accounting platforms.
