“If it is not on the phone with GPS and photos, it did not happen.”

Project Overview

The business context

How the engagement started, what was broken, and why a platform investment was required.

Field electricians, dealers, vendors, and customers needed purpose-built apps. Paper checklists and personal-phone photos created disputes, missing GPS proof, and delayed approval packages for the web desk.

We built a suite of mobile applications that execute the installation on site. Electricians run inspections and installs with GPS verification and photo evidence; dealers and vendors track jobs; customers receive status and capture signatures and feedback — all syncing to the web command center.

Mobile eliminates paper job sheets, missed geo-proof, and delayed status updates from the field.

Discovery

Ride-alongs and job-shadowing revealed that electricians need fast job queues, offline tolerance, mandatory photo sets, geo-fence check-in, and a frictionless customer signature moment before leaving the site.

Business Challenge

What was holding the operation back

Field teams worked offline from HQ systems. Photos lived on personal phones, GPS proof was missing, and customers had no transparent status — creating disputes and rework.

01

Paper checklists on job sites

02

No GPS proof of attendance

03

Photos not linked to work orders

04

Customers unaware of ETAs

05

Signatures collected on paper

06

Rework from incomplete evidence

07

Electrician productivity untracked

08

Push updates missing for dealers

Our Approach

How Quantum Infoway delivered

A consulting-led build: discover, design operating model, ship vertical slices, harden for audit.

Role-specific native-quality apps with geo-fencing, camera workflows, digital signatures, QR kit scanning, and push notifications tied to the web order lifecycle.

  1. 01

    We shipped four role-specific apps — Electrician, Dealer, Vendor, and Customer — sharing a design system and the same order API as the web platform.

  2. 02

    Geo-fencing and GPS verification establish attendance integrity; QR scanning ties physical kits to digital work orders.

  3. 03

    Photo evidence and digital signatures are uploaded as signed artifacts so the web inspection desk can approve without chasing files.

  4. 04

    Push notifications keep dealers and customers aligned on ETAs, completion, and feedback — closing the loop the same day.

Delivery story

Mobile delivery emphasized offline job caches, background sync, and camera reliability across mid-range Android devices common in field crews. QA scenarios covered weak networks, incomplete checklists, and rework loops after desk rejection.

Impact & outcomes

Installations left the job site with complete evidence packs. Customer ratings improved as status became transparent. Dealers verified work from their phones. Rework fell because incomplete submissions were blocked before sync.

Enterprise field work only transforms when mobile apps enforce process quality — not when they simply display tickets. This suite makes proof, place, and time first-class.
