Where we work

Headquartered in La Louvière (Hainaut), we serve clients across Belgium and Europe:

  • • Wallonia: La Louvière, Mons, Charleroi, Liège, Namur, Tournai, Binche, Soignies — French-speaking clients, on-site meetings possible.
  • • Brussels & EU institutions: bilingual FR/EN delivery, expat-friendly communication, GDPR-compliant by design.
  • • SHAPE / Casteau community: NATO contractors, international schools, military families — English-first websites and apps.
  • • Flanders & Netherlands: bilingual FR/NL or EN/NL projects, remote-first collaboration.
  • • Remote Europe-wide: any client in EU timezones — async-friendly workflow.

What we don't do — honestly

We turn down about 30% of incoming projects when we're not the right team. Here's when to call someone else:

  • ❌ Native iOS/Android apps — we build PWAs only. For native, we recommend dedicated mobile shops.
  • ❌ Pure SEO content writing (no dev) — we focus on technical SEO + page structure. For deep content marketing, work with content specialists.
  • ❌ Branding & logo design — we deliver design implementation, not brand strategy. Bring your brand guidelines (or we'll recommend a designer).
  • ❌ Projects under 1.000€ — we can't deliver our quality at lower price points. For very small budgets, look at templates + freelancers.
  • ❌ Enterprise IT migrations (SAP, Oracle, etc.) — out of our scope. We focus on web tech specifically.

FAQ — Web development in Belgium

Where are you based?

FlowBelgium is based in La Louvière (Hainaut province, Belgium), 30 km from Mons and 50 km from Brussels. We work remotely with clients across Belgium and Europe — Brussels, Antwerp, Ghent, Liège, Charleroi, Mons, Namur — and travel for project kick-offs.

Do you work with English-speaking clients?

Yes — about 20% of our clients communicate primarily in English. We reply within 24h in English, deliver documentation in English, and can write all code comments and commit messages in English. Especially relevant for expat communities (SHAPE/Casteau, EU institutions in Brussels) and international clients.

What does web development cost in Belgium?

Marketing website: from 1.000€ excl. VAT + 60€/month (maintenance + hosting, billed from go-live). E-commerce and custom platforms: quote-based after a 30-min scoping call. Web app MVP: from 4.000€ excl. VAT. Custom SaaS platform: 15.000€ - 50.000€ excl. VAT.

How long does it take to build a website or web app?

Marketing website (1-5 pages): 3 weeks. Bilingual marketing site (FR/EN or FR/NL): 4-5 weeks. Web app MVP: 4-6 weeks. Full custom application: 2-4 months. SaaS platform: 3-6 months. We deliver in weekly increments — you see and use the product from week 2, not at a final big-bang launch.

What tech stack do you use, and why?

Next.js 16 (React 19) for frontend — best-in-class performance, SEO-friendly, server-side rendering. Supabase (Postgres) for backend — open-source, hostable in Europe, no Google lock-in. TailwindCSS for styling, shadcn/ui for components. TypeScript strict everywhere. n8n for workflow automation. Vercel for hosting. We've made these choices based on 5+ years of production experience, not because they're trendy.

Can you handle hosting, maintenance, and ongoing support?

Yes — maintenance & hosting package: 60€/month excl. VAT for standard sites. Includes monitoring, backups, dependency updates, security patches, minor content edits. For larger apps, custom support agreements available. You can also self-host if you prefer — we hand over the code and infrastructure docs.

Do you do mobile app development?

We don't do native iOS/Android (Swift/Kotlin) — that's a different specialty. We build Progressive Web Apps (PWAs) which cover 90% of mobile use cases at 30% of native cost: install on home screen, push notifications, offline mode, full mobile UX. For pure native apps, we can recommend partners.
