Chapter One

The Problem

Paper PODs took 6 days to reach billing. Drivers on rural routes lost signal for hours, and the previous app simply failed.

Before our intervention:

  • 6-day POD turnaround
  • Paper-based disputes
  • App unusable offline
Chapter Two

The Outcome

Depot-by-depot rollout with printed quick-start cards in three languages.

After launch:

  • Same-day POD sync
  • Photo + GPS evidence per stop
  • 100% offline capability
Deep Dive

How we designed and engineered it

01. Research

Discovery & Insights

We rode along on 14 routes and logged connectivity. 38% of delivery stops had no usable data connection.

02. Design

UX & System Design

A three-tap delivery flow with oversized targets, works-in-sunlight contrast, and a sync status that never lies.

03. Build

Engineering & Quality

Local-first SQLite store, conflict-safe sync queue, compressed photo PODs and signature capture.
