Multilingual Website Cost in Brussels in 2026

The verdict in three sentences

A multilingual corporate website in Brussels costs, in 2026, between EUR 10,000 and 26,000 for the technical foundation, plus EUR 1,800 to 4,500 per additional language. The real budget is driven not by design but by hreflang architecture, per-language editorial governance, and professional translation. Done well, a trilingual site delivers on average +30% international leads in the first year — a fast payback for an exporting mid-market firm.

What the budget actually covers

A multilingual site is not a single-language site translated three times. You need architecture that correctly declares each version to search engines (hreflang tags), a CMS where each language is a distinct editorial space, and a per-country validation workflow. Here is the 2026 pricing structure for Brussels.

A common mistake: underestimating the recurring cost of translation. Every new product or news page must be translated into all languages, or the experience degrades and SEO suffers.

Brussels vs Paris vs Geneva comparison

Francophone European markets are not equal. Brussels often requires FR/NL/EN, which raises the foundation cost. Geneva pushes prices up through high local labour rates.

For a Brussels mid-market firm, the 2026 reference range is EUR 10,000 to 26,000 for a full trilingual site, including twelve months of maintenance.

Mini case study

Sophie, marketing director of an industrial mid-market firm in Brussels (45 staff, 40% export revenue), wants an FR/NL/EN site. Foundation at EUR 16,000, two additional languages at EUR 3,200 each, translation of 60 pages at roughly EUR 4,800. Initial investment: EUR 27,200, plus EUR 480/month for maintenance and hosting. Her old site produced 12 qualified leads/month. With trilingual coverage and solid international SEO she reaches 17 leads/month, 4 of them outside Belgium. At a 20% conversion rate and an average project value of EUR 18,000, those 4 leads add roughly EUR 173,000 of annual pipeline. The site pays for itself by the second month of operation.

FAQ

How much does an extra language really cost? Budget EUR 1,800 to 4,500 per language in 2026 for integration, plus per-word translation (EUR 0.12-0.22). A language added later, on a foundation not built for it, often costs 30 to 50% more.

Is hreflang essential? Yes. Without correct hreflang tags, Google serves the wrong version to visitors and duplicates your content, hurting rankings. It is a non-negotiable EUR 2,000-5,000 item for a genuine international site.

Translate or localise? Literal translation rarely suffices in B2B. Localisation (adapting examples, currencies, references) costs 15 to 25% more but often doubles conversion on target markets.

What timeline should I expect? Budget 9 to 13 weeks for a trilingual site in Brussels: 3 weeks of design, 4-6 of development, 2-3 of translation and per-language QA.

Can I add languages later? Yes, if the foundation is built multilingual from the start. That is why you must invest in architecture at launch, even if you begin with two languages.
