Driver app
Offline-capable job list, optimised stop sequence, navigation handoff, status updates, photo and signature proof, and per-shift cash ledger.
We built a real-time delivery platform covering 12 cities with a driver app, customer app, and admin dashboard, delivered in 14 days. Throughput rose 340%, and the reason was automated dispatch replacing a person assigning every job by hand.
The engineering that matters is not the map. It is what happens when the driver has no signal, the customer is not home, and the cash has to reconcile at the end of the shift.
What the platform is made of
Customer tracking
A tracking link by SMS or WhatsApp that opens without an install, showing live position, ETA, and contact options.
Dispatch dashboard
Live map, rules-based auto-assignment with manual override, exception queue, SLA monitoring, and reporting.
Core features we build
- Offline-first driver app with queued sync
- Rules-based dispatch by zone, capacity, and proximity
- Multi-stop route sequencing with time windows
- Proof of delivery: photo, signature, and geotagged timestamp
- Structured failure reasons with automatic reschedule or return
- No-install customer tracking link
- Adaptive location sampling to protect driver battery
- Per-driver cash ledger with shift reconciliation
- Third-party courier handoff for overflow
- SLA monitoring with alerts before a breach, not after
What drives the cost
We quote every build individually because these factors move the number more than any feature list does:
| Factor | Why it matters |
|---|---|
| Fleet size and concurrency | Real-time position for large fleets changes infrastructure design |
| Route optimisation depth | Simple sequencing versus constrained optimisation differ substantially |
| Third-party carrier integration | Each carrier is a separate integration |
| Cash handling | COD reconciliation adds ledger and reporting work |
| Customer-facing surfaces | A tracking link is cheaper than a full customer app |
| Warehouse integration | Scanning and dispatch integration adds scope |
Send your feature list and you get a fixed written price within 24 hours, with the scope it covers and a delivery date.

Questions, answered.
Does the driver app work without internet?
Yes, by design. Jobs are cached on the device, status updates, photos, and signatures queue locally, and everything syncs on reconnect. Basement car parks and rural routes are normal conditions, not exceptions.
Do customers need to install an app to track their delivery?
No, and they should not have to. A tracking link sent by SMS or WhatsApp opens in a browser and shows live position, ETA, and a contact option. This is typically the largest single reduction in inbound support calls.
How does automatic dispatch work?
Rules you configure — zone, vehicle capacity, current load, and proximity — assign jobs without a person deciding each one, with manual override always available. Removing that manual bottleneck is what produced the 340% throughput increase for our logistics client.
Can it hand overflow to third-party couriers?
Yes. When your own fleet is at capacity, jobs can be routed to an integrated carrier and still tracked in the same dashboard, so operations keep one view rather than checking several portals.
How do you handle cash on delivery?
Each driver has a cash ledger recording collections per order, reconciled at shift end against what is handed in, with variances flagged to a supervisor. Without this, COD becomes a permanent manual reconciliation burden.
Six things we put in writing.
Not values on a wall — contract terms. Ask any other supplier to match them line by line.
A price in 24 hours
Send a brief, get a fixed written price and a delivery date the next working day. Free, no obligation, and the scope document is yours to keep even if you go elsewhere.
The price does not move
Fixed, not an estimate. If scope changes we re-quote in writing and you approve before we build it. You will never open a surprise invoice.
Half on delivery
50% to start, 50% when it is live and you are satisfied. You never fund the whole project up front.
Unlimited design revisions
We do not write production code until you approve the screens. Changing your mind at that stage costs nothing.
You own everything
Full source code, design files and credentials on delivery. No licence, no platform fee, nothing that stops another developer taking over.
30 days of fixes included
Free bug fixing for a month after launch, then an optional retainer only if you want one.
Every one of these is in the agreement before you pay anything. See how we evidence our claims →
