The verdict in three sentences
The last mile is where a delivery service's customer satisfaction and margin are decided. A complete delivery application (driver app with geolocation, real-time customer tracking, proof of delivery, notifications) costs 35,000 to 90,000 EUR over 14 to 22 weeks. The return shows first in the customer relationship: +18 NPS and -45% support calls, two direct B2B retention levers.
Native app vs PWA: which to choose?
The technical choice drives budget and field experience. Here is a 2026 comparison.
| Criterion | PWA (web app) | Native app (iOS/Android) |
|---|---|---|
| Build cost | 35,000 to 55,000 EUR | 55,000 to 90,000 EUR |
| Timeline | 14 to 18 weeks | 18 to 22 weeks |
| Background geolocation | limited | full |
| Push notifications | decent | reliable native |
| Scan / proof photo | yes | yes, smoother |
| Store publication | not required | App Store + Play Store |
| Best for | customer tracking, MVP | intensive driver app |
Many services start with a customer-side PWA (tracking + notifications) and a native driver app for background geolocation and scanning.
The cost of mapping and geolocation
Real-time tracking relies on a maps and routing provider. These costs are recurring and must be budgeted.
| Item | Mapbox | Google Maps Platform |
|---|---|---|
| Map load | ~5 EUR / 1,000 loads | ~7 EUR / 1,000 loads |
| Route calculation | ~2 EUR / 1,000 requests | ~5 EUR / 1,000 requests |
| Address geocoding | ~4.50 EUR / 1,000 | ~5 EUR / 1,000 |
| Free monthly credit | variable | ~200 USD |
| Estimated monthly cost (5,000 deliveries) | 150 to 400 EUR | 250 to 600 EUR |
At moderate volume, Mapbox is often 30 to 40% cheaper; beyond that, a commitment deal is worth negotiating with both providers.
The measurable business impact
| Indicator | Before the app | After the app |
|---|---|---|
| Customer NPS | 32 | 50 (+18) |
| "Where is my order" support calls | base 100 | 55 (-45%) |
| First-attempt delivery rate | 84% | 93% |
| "Parcel not received" disputes | 3.2% | 1.1% |
| Contestable proof of delivery | frequent | timestamped + photo |
Timestamped proof of delivery with photo and signature removes most "I never received it" disputes, which cost dearly in credit notes and time.

Yasmine, founder of an urban delivery service in Bordeaux, handles 5,000 deliveries/month with 12 drivers. Her support desk handles 900 "where is my order?" calls per month, each taking ~6 minutes, i.e. 90 monthly hours at ~28 EUR loaded = 2,520 EUR/month. An app at 62,000 EUR (amortized 3 years = ~20,700 EUR/year, i.e. 1,725 EUR/month) plus 350 EUR of mapping cuts those calls by 45%: she recovers ~1,134 EUR/month on support, and above all gains +18 NPS improving retention of her B2B accounts. The app self-funds through reduced support and disputes alone by year two.
FAQ
How long to launch the app?
From 14 to 22 weeks. A customer-tracking PWA can ship in 14 weeks; the native driver app with background geolocation takes 18 to 22 weeks plus store review.
Do we pay Mapbox or Google Maps forever?
Yes, these are recurring usage costs: budget 150 to 600 EUR/month depending on volume and provider. We optimize by caching maps and limiting unnecessary route recalculations.
Is proof of delivery legally solid?
Timestamped proof with geolocation, photo and electronic signature forms a very strong body of evidence in disputes, dropping "parcel not received" contests below 1.5%.
Can the app connect to our TMS or ERP?
Yes, via API. Delivery orders flow from the TMS to the driver app, and statuses (picked up, delivered, failed) flow back in real time. Budget 5,000 to 12,000 EUR of integration.
How do we handle no-network zones?
The driver app works offline: it buffers positions, photos and signatures, then syncs as soon as connectivity returns, never blocking a route.
