Multilingual B2B website for export markets (2026)

The verdict in three sentences

A trilingual FR/EN/DE export website costs 12,000 to 28,000 EUR in 2026, roughly +30 % versus an equivalent single-language site. The premium comes from professional translation (0.10 to 0.18 EUR/word), hreflang markup and a CMS that cleanly manages language versions. Built and indexed properly, it captures 2 to 3 times more qualified export leads than a patched-together English-only version.

Why multilingual changes the export game

An Alsatian mid-cap selling industrial components into Germany and the Czech Republic cannot rely on English alone. The German technical buyer searches in German, evaluates in German and trusts a supplier who speaks the language. A well-localised FR/EN/DE site is not word-for-word translation: it adapts messaging, units, normative references (DIN, CE) and market examples.

Hreflang tells Google which version to serve to which market. Without it, the French version may surface in Germany and lose the prospect in three seconds. With clean markup, each market sees its own language and bounce rate drops sharply.

Translation, timelines and CMS choice

Translation is the most sensitive variable cost. Budget 0.10 to 0.18 EUR/word for professional technical FR-to-DE translation, versus 0.04 to 0.06 EUR/word for post-edited machine translation (fine for secondary content, risky for product sheets). A 15-page B2B site runs roughly 12,000 to 20,000 words per language.

A typical trilingual timeline is 8 to 12 weeks: 3 to 4 weeks of design and structure, 3 to 4 weeks of build and parallel translation, 2 to 3 weeks of QA and indexing. A natively multilingual CMS (with per-language trees) avoids costly maintenance patches.

Mini case study

Thomas, export sales director at a 90-person mid-cap in Strasbourg, generated 4 German leads a month via an English-only site. He invests 19,000 EUR in an FR/EN/DE site with hreflang and localised product sheets. Within 5 months, Germany/Austria leads rise to 11 per month, 6 of them qualified. With an average export deal of 24,000 EUR and an 8 % conversion rate, that means about 1 extra signed deal per month, or ~288,000 EUR of additional annual revenue. The site pays for itself in under 2 months of margin.

FAQ

Do I need a domain per language?

Not mandatory. A single domain with subfolders (/de/, /en/) and correct hreflang covers 90 % of cases at no extra cost. Country domains (.de) add slight trust but multiply maintenance costs by 2 to 3.

Can I add a language later?

Yes, if the CMS is multilingual from the start. Adding Italian or Polish then mainly costs translation (2,500 to 5,000 EUR/language) plus 1 to 2 weeks of integration, versus a full rebuild if the architecture was not planned.

Is machine translation enough for B2B?

No for product and key pages. A technical terminology error in German destroys credibility. Reserve post-edited machine translation for secondary content (blog), around 20 to 30 % of volume.

What is annual maintenance?

Budget 1,500 to 3,500 EUR/year for a trilingual site: security updates, hosting, per-market SEO tuning. Each language adds roughly 20 % of editorial maintenance load.

Is hreflang really essential?

Yes for export. Without it, Google often serves the wrong language and you lose 30 to 50 % of potential international traffic. It is an 1,800 - 3,500 EUR item but decisive for ROI.
