Building a product for the European market: what to plan for
The EU is one market for regulation but many markets for users. A launch in Germany, the Netherlands and Sweden means three languages, three favourite payment methods and very different expectations about privacy prompts. These are the decisions we make with European clients in the first weeks of a project.
1. Decide where personal data lives
Most of our European clients host in an EU region — Frankfurt, Ireland, Paris or Stockholm on AWS, or the equivalent Azure and Google Cloud regions. If your customers are public bodies or regulated enterprises that ask for sovereignty guarantees, the AWS European Sovereign Cloud in Germany (generally available since January 2026) is operated by EU residents only. We keep a written list of every sub-processor the app uses (email, analytics, crash reporting, AI APIs) so your privacy notice and records of processing stay accurate.
2. Treat accessibility as a feature, not an audit
Under the European Accessibility Act, online shops, consumer banking apps, e-book apps and passenger-transport booking apps must be accessible, with a transition period to 2030 only for services delivered on products already in use. Microenterprises are exempt for services, but most growing companies won't stay micro for long. Building it in from the start — semantic components, sufficient contrast, scalable text, screen-reader labels, keyboard and switch access — costs far less than retrofitting a finished app.
3. Plan languages and formats early
We set up internationalisation before the first screen is built: translatable strings, plural rules, local date, number and currency formats, VAT-inclusive pricing and layouts that survive German words that are much longer than their English equivalents. Translation itself is best done by your native-speaking team or a professional agency; we provide the workflow and the screenshots for context.
4. Check payments country by country
A card-only checkout loses customers in markets where people prefer bank payments. The Netherlands is moving from iDEAL to Wero by the end of 2027, Belgium relies on Bancontact, Poland on BLIK and the Nordics on Vipps MobilePay and Swish. Since October 2025, every euro-area bank has had to offer instant SEPA transfers, which makes pay-by-bank flows more practical. We pick a payment provider that covers your launch countries and leave room to add more.
5. Put the AI Act on the roadmap
Prohibited AI practices have been banned since February 2025 and general-purpose AI model rules have applied since August 2025. For most products we build, the obligations that matter are transparency: from 2 August 2026 people must know when they are talking to a chatbot, and synthetic images, audio and text must be marked. After the 2026 "digital omnibus" amendment, obligations for high-risk uses such as recruitment, credit and education now apply from 2 December 2027. If your feature might fall into one of those categories, we keep the documentation and test evidence you will need as we go. Our EU app compliance checklist summarises every 2026–2027 deadline in one place.
6. Connected devices and the Data Act
If your app controls a connected product — a car charger, a smart meter, a fitness device — the Data Act has applied since September 2025, and products and companion apps placed on the market from 12 September 2026 must let users access the data they generate by design. We include data export and sharing APIs in the architecture rather than adding them under pressure later.
How an engagement with a European client usually runs
- Discovery call in your morning, followed by a written proposal with scope, team and a fixed price or monthly rate.
- Contract pack: services agreement, NDA, data processing agreement and Standard Contractual Clauses.
- Sprint 0: architecture, privacy and accessibility plan, design system and backlog.
- Build with daily updates, a weekly demo and a staging environment you can test on.
- Launch and support: security and accessibility testing, store submission and a support plan.
As a rough guide, a focused MVP usually costs US$5,000–$15,000, a mid-sized app $15,000–$40,000 and complex platforms start from around $40,000, delivered in phases. Compliance-heavy features add to that, and we price them openly. Read our guide to outsourcing app development to Pakistan for a fuller picture of costs and risks.
