Proof of Delivery System
How we built a real-time delivery tracking platform with driver mobile app, WebSocket location updates, digital signatures, and photo confirmation — processing 10,000+ deliveries per month.
01 — The Problem
A logistics company with no visibility into its own deliveries
A regional logistics and courier company was handling thousands of deliveries monthly with zero real-time visibility. Dispatchers called drivers to get status updates. Proof of delivery was a paper slip that often got lost. Customer complaints about missing deliveries were impossible to resolve without evidence.
They needed a system that could prove every delivery happened, track drivers in real time, and eliminate paper entirely.
"We were spending 2 hours a day on calls with drivers asking where they were. We had no way to prove to customers that a delivery actually happened."
— Dispatch Manager
- No real-time driver location tracking — updates only via phone calls
- Paper proof-of-delivery slips frequently lost or illegible
- No photo confirmation — impossible to prove damaged/missing deliveries
- Customers had no visibility into their delivery status
- Dispatch team manually assigned routes with no optimisation
02 — The Solution
Driver mobile app + WebSocket dashboard + digital proof
- Driver Mobile App (React Native)
Drivers use the app to view their daily manifest, navigate to each stop, capture digital signatures, photograph delivered packages, and mark deliveries complete — all offline-capable with sync on reconnect. - WebSocket Live Tracking
Driver locations broadcast to the dispatch dashboard in real time via WebSocket — showing all active drivers on a map with delivery status and ETA calculations. - Digital Signature & Photo Capture
Each delivery requires recipient signature (touchscreen) and package photo — automatically attached to the delivery record with timestamp and GPS coordinates. - Customer Tracking Portal
Customers receive an SMS link to track their delivery in real time — showing driver location, estimated arrival, and delivery confirmation with signature image. - Dispatch Dashboard
Full delivery manifest management, driver assignment, route overview map, exception alerts (failed deliveries, route deviations), and end-of-day reporting.
