The verdict in three sentences
For a CIO in Amsterdam equipping 80 field technicians (maintenance, after-sales, installation), a PWA covers most field needs in 2026: work orders, offline mode, photos, customer signature, geolocation. A native app is only justified for specific hardware use (Bluetooth on iPhone, NFC, heavy background tasks) or public distribution on app stores. Local agencies quote 30,000 to 60,000 EUR for a PWA and 60,000 to 150,000 EUR for two native apps, while Kolonell delivers a business PWA from 4,000,000 FCFA (6,100 EUR).
What a PWA can and cannot do in 2026
Mobile browsers have come a long way, but Safari on iPhone remains more limited than Chrome on Android. The table below works as a feature-by-feature decision grid.
| Field feature | PWA on Android (Chrome) | PWA on iPhone (Safari) | Native app |
|---|---|---|---|
| Offline mode (orders, sheets, forms) | Yes | Yes | Yes |
| Photos and annotations | Yes | Yes | Yes |
| Customer signature on screen | Yes | Yes | Yes |
| Geolocation while in use | Yes | Yes | Yes |
| Push notifications | Yes | Yes since iOS 16.4, if installed to home screen | Yes |
| Bluetooth (probes, portable printers) | Yes (Web Bluetooth) | No | Yes |
| NFC reading (badges, tags) | Yes (Web NFC) | No | Yes |
| Background sync, continuous location | Limited | Very limited | Yes |
| Barcode and QR scanning | Yes | Yes | Yes |
If your fleet runs on Android, or your technicians use neither Bluetooth probes nor NFC badges, a PWA is enough. If 30% of the fleet uses iPhones and must drive a Bluetooth printer, you need a native app or a targeted native module.
Cost and timeline: the 2026 comparison
The market ranges below are 2026 estimates for a field service tool with 10 to 15 screens, sync with the ERP or maintenance system, and a scheduling back office.
| Option | Upfront budget | Timeline | Annual maintenance | Distribution |
|---|---|---|---|---|
| PWA, Amsterdam agency (market estimate) | 30,000 to 60,000 EUR | 3 to 4 months | 15 to 20% of initial budget | Link or install from browser |
| Native iOS and Android apps, agency (market estimate) | 60,000 to 150,000 EUR | 4 to 7 months | 15 to 25% of initial budget | App Store and Google Play, or MDM |
| Cross-platform (Flutter, React Native), agency (market estimate) | 40,000 to 90,000 EUR | 3 to 5 months | 15 to 20% | Stores or MDM |
| Kolonell, medium business PWA | 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) | 8 to 12 weeks | 35,000 to 120,000 FCFA per month | Secure link, one-tap install |
| Kolonell, PWA with complex integrations or native module | 10,670 to 22,870 EUR and up (7,000,000 to 15,000,000 FCFA and up) | 3 to 5 months | On quote | PWA plus targeted native app |
Native also adds developer accounts (99 USD a year with Apple, 25 USD once with Google), store reviews of 1 to 3 days per release, and often an MDM tool for internal distribution, estimated at 3 to 8 EUR per device per month.
The hidden costs people forget
| Item | PWA | Native app |
|---|---|---|
| Updates | Instant, on next load | Store review, then gradual adoption over 1 to 3 weeks |
| Number of codebases | 1 | 2 (or 1 with cross-platform) |
| Testing | Chrome and Safari browsers | iOS and Android versions, device models |
| Older smartphone support | Broad | Regular drop of old OS versions |
| Developer profile | Web, easier to hire | Mobile, scarcer and pricier |
For an internal tool, instant updates are often decisive: fixing a work order form in the morning and seeing it live by noon avoids days of re-entry.

Illustration: Daan, CIO of an HVAC maintenance company in Amsterdam, equips 80 technicians, 70% of them on Android. The agency he consulted proposes two native apps at 100,000 EUR, with 18,000 EUR of maintenance per year. Over 3 years, the total cost reaches 154,000 EUR.
With a Kolonell PWA at 6,000,000 FCFA (9,150 EUR) and Premium maintenance at 120,000 FCFA per month (about 2,200 EUR a year), the 3-year cost comes to around 15,750 EUR. The 30% of technicians on iPhone do not use Bluetooth accessories, so no feature is missing. The 138,000 EUR gap over 3 years easily funds the maintenance system integration and team training.
FAQ
Does a PWA really work without a network?
Yes, thanks to the service worker and local storage, work orders, sheets and forms stay available offline. Sync happens when the network returns; plan 50 to 200 MB of storage per device depending on photo volume.
Can a PWA be published on the App Store or Google Play?
On Google Play, yes, through a light wrapper that takes 2 to 4 days of work. On the App Store, Apple requires genuine native value, and for an internal tool, distribution by link or MDM remains simpler.
Do push notifications work on iPhone?
Since iOS 16.4, yes, provided the PWA is added to the home screen. A guided 3-step install screen inside the PWA usually gets over 90% of technicians installed.
How long does a business PWA take to deliver?
Allow 8 to 12 weeks for a full version with scheduling, offline mode and ERP sync. A pilot with 10 technicians can start from week 6.
What if we need a native feature later?
The PWA can be extended with a small targeted native module, for example for Bluetooth on iPhone. This usually costs far less than a rewrite, with an overall budget in the 10,670 to 22,870 EUR range (7,000,000 to 15,000,000 FCFA).
Let's scope your project. A business PWA for your technicians, with offline mode, customer signature and ERP sync, scopes at 6,100 to 10,670 EUR for delivery in 8 to 12 weeks. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
