Cost of a PWA vs. Native App for an Online Store

The cost of a PWA or native app is a critical financial decision for your online store. While native development often requires tens of thousands of euros for two separate systems, a Progressive Web App offers a seamless smartphone experience with a much more accessible budget and lower operating expenses.

Why is mobile becoming a financial black hole for e-merchants?

Traffic from smartphones now far exceeds desktop traffic for most merchant sites. However, many merchants notice a painful gap between this volume of visitors and actual completed orders. A standard site that is poorly adapted, slowed down by unnecessary scripts, or hindered by a laborious checkout process drives away hurried buyers.

To solve this conversion problem, the classic mistake is to rush into creating downloadable apps for iOS and Android. Quotes quickly skyrocket because you have to fund two projects in parallel: designing an app for Apple, then doing it all over again for the Google ecosystem. For an SME, this double investment drains cash flow at the expense of customer acquisition and inventory management.

Adding to this is a persistent myth: believing that being on the App Store or Google Play guarantees immediate sales. In reality, convincing a passerby to download an app of several dozen megabytes before their first purchase has become almost impossible. Your customers want instant access to your catalog, without friction or app account passwords to reset.

PWA or native app: what are the initial investment differences?

A Progressive Web App (PWA) is a modern website that uses recent web technologies to behave exactly like an installed mobile app. The user can add it to their home screen with one click, receive notifications, and browse even with an unstable connection, all without going through an app store.

Financially, the initial gap between these two approaches is massive:

• The PWA relies on a single codebase: the same development serves your site on desktop, tablet, iPhone, and Android. You only pay for one interface developed with technologies like React or TypeScript.
• Native multiplies development: if you choose to design in Swift for iOS and Kotlin for Android, every feature of the cart or catalog is coded twice. Even using cross-platform technologies like React Native or Flutter, the system-specific adjustments and testing on dozens of devices require significant work time.
• Immediate administrative costs: publishing on stores requires opening an Apple Developer account charged at $99 per year, as well as a Google Play Console account. These steps do not exist with independent web development.

What are the real maintenance and operating costs over three years?

The initial cost of a project is only part of the financial equation. Over a three-year period, the running costs of a native app can quickly exceed its initial creation cost.

The first expense category involves transactions. If you sell digital products or certain services via a native app, Apple and Google take commissions between 15% and 30% on every payment. In contrast, on an online store running as a PWA, you keep 100% of your margins by using direct payment gateways like Stripe, where fees remain standard and predictable.

The second invisible expense concerns mandatory updates. Every year, Apple and Google release new versions of their operating systems (iOS and Android). These technical changes require revising your native app code, renewing security certificates, and resubmitting the app to moderation teams under threat of removal. A PWA hosted on your own server is not subject to any censorship or forced schedules.

Finally, connecting your catalog requires a solid architecture. A native app demands a dedicated API and permanent database synchronization. To learn more about this central aspect, check out our comparison on the cost to synchronize stock and online store.

What budget should you plan for based on your online store's complexity?

To make a rational decision, you must precisely calculate both technical paths. Here are the budget benchmarks I regularly observe on real merchant projects.

Expect from €3,000 to transform an existing e-commerce catalog into a fast and modern PWA. This starting point includes a fluid mobile interface, page caching for instant loading, and direct installation on smartphones. The price then evolves according to the number of integrations needed, especially if you are planning a complete platform inspired by the cost of an ordering and delivery app for e-commerce.

For an equivalent native app distributed on both stores, expect from €15,000. The amount climbs as soon as you have to maintain two user interfaces, manage native push notification gateways, and build secure APIs to feed each screen.

Certain hardware functions change the budget. If you want to integrate barcode scanning via the camera or partial offline functionality, these options fit very well into a modern PWA today without excessive extra costs. Very heavy features, such as complex 3D augmented reality or access to health sensors, do however justify using native.

An online store wins customers through browsing speed and payment simplicity, two qualities perfectly delivered by a PWA for a fraction of the cost of native development.

How do I design a profitable mobile app for your store?

As an independent developer since 2017, I design and develop business tools, web apps, and complete e-commerce platforms. When a merchant asks me about the cost of a PWA vs. a native app, my priority is not to sell them the most expensive technology, but the one that preserves their profitability.

My work is based on a clear method to make your investment profitable:

1. Audit of your metrics and buyers: I first analyze the origin of your orders, the smartphone models most used by your customers, and the bottlenecks that hinder your shopping cart.
2. A streamlined technical architecture: I use PHP and Python on the server side with React and TypeScript for the interface to guarantee minimal loading times, even on unstable 4G. You can examine my concrete solutions via my app and platform projects.
3. A single point of contact from start to finish: I link your Stripe payment system, your inventory management, and the mobile display directly, without involving an army of intermediaries that inflates agency quotes.

If your activity relies on specific internal logistical needs, it is often wiser to pair a merchant PWA with custom e-commerce management software rather than sinking your entire budget into a mass-market native app.

What are the next steps to launch your mobile project?

Before requesting a quote or committing to development expenses, you must clarify your functional requirements to avoid unnecessary options.

• List the 5 features that are truly essential for purchasing from you (quick search, clear filters, saved cart, one-click payment).
• Measure the exact share of your mobile traffic compared to your actual sales.
• Check if your catalog really requires native hardware sensors or just an ultra-fast interface.
• Estimate the gain generated if your mobile conversion rate increased by just 0.5% over the coming year.
