The verdict in three sentences
A business PWA (Progressive Web App) delivers offline mode, home-screen install and push notifications without the App Store or Google Play, for a 2026 budget of 25,000 to 55,000 EUR. It runs on a single codebase shared with your web app, whereas native requires two (iOS + Android), adding 60-100 % to the cost. For field, mobility and logistics use cases, a PWA covers 85 % of real needs at half the price.
What a business PWA really costs
A business PWA is more than a responsive site: it ships a service worker (offline cache), install manifest, deferred sync and push. Budget is driven by screen count, offline complexity and integrations (ERP, GPS, barcode scan).
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Discovery & UX (field flows) | 3,000 - 7,000 | Wireframes, IA, offline flows |
| UI design + design system | 4,000 - 9,000 | Reusable components, dark mode |
| Front-end (PWA shell) | 8,000 - 18,000 | Service worker, cache, manifest |
| Offline mode + sync | 4,000 - 10,000 | IndexedDB, sync queue, conflicts |
| Push notifications | 1,500 - 4,000 | Web Push API, VAPID, targeting |
| Integrations (API/ERP) | 3,000 - 9,000 | Auth, endpoints, webhooks |
| QA + UAT + go-live | 2,500 - 6,000 | Multi-device, Lighthouse |
| Total | 25,000 - 55,000 | 3 to 6 months |
2026 order of magnitude: a median project (12-18 screens, partial offline, push) lands near 38,000 EUR over 4 months of delivery.
PWA vs native app: the decision comparison
| Criterion | PWA | Native (iOS + Android) |
|---|---|---|
| 2026 build cost | 25,000 - 55,000 EUR | 60,000 - 120,000 EUR |
| Codebases | 1 (shared web) | 2 (Swift + Kotlin/RN) |
| Distribution | URL, QR, installable | Stores, 1-7 day review |
| Annual fees | Hosting only | 99 EUR Apple + 25 EUR Google |
| Offline mode | Yes (service worker) | Yes (native) |
| Push | Yes (iOS 16.4+ included) | Yes |
| Advanced hardware access | Partial (Bluetooth, limited NFC) | Full |
| Updates | Instant (web deploy) | Store submission per release |
| Average timeline | 3 - 6 months | 5 - 9 months |
PWA wins whenever fast distribution, simple maintenance and budget matter. Native stays justified for consumer apps that depend on store discovery, or heavy hardware access (sensors, ARKit, fine biometrics).
Mini case study
Nadia, operations director at an industrial maintenance firm in Nantes (40 field technicians). Her teams filled paper reports re-keyed by hand: 25 min/day/technician lost, plus 6 % billing errors. She commissions an offline-first intervention-report PWA at 41,000 EUR.
Gain: 25 min × 40 techs × 220 days = 3,667 hours/year recovered. At 35 EUR/h loaded cost, that is 128,000 EUR/year. Adding recovered billing errors (≈ 18,000 EUR), payback lands in under 4 months. No store fees, updates pushed overnight.

FAQ
Does a PWA truly work offline?
Yes: the service worker caches the interface and data, and a sync queue replays actions once the network returns. Ideal for field work (sites, dead zones) where 3G/4G is unreliable.
Do push notifications work on iPhone?
Since iOS 16.4 (2023), installed PWAs support Web Push. By 2026 it is mature, covering iPhone and Android alike, without store fees or friction.
Can you still publish a PWA to the stores?
Yes, via a wrapper (Bubblewrap/TWA for Android, PWABuilder). Budget an extra 1,500-4,000 EUR to package and manage store listings if visibility requires it.
What is a realistic timeline for a first version?
A useful business PWA MVP ships in 8-12 weeks; the full version with advanced offline and ERP integrations in 3-6 months depending on scope.
What annual maintenance budget should I plan?
Expect 15-20 % of the build per year (≈ 5,000-10,000 EUR) for features, security and browser compatibility, plus hosting (often 50-200 EUR/month).
