The verdict in three sentences
A trilingual EN/DE/NL 12-page showcase site costs in 2026 between EUR 9,500 and 19,000 in Amsterdam, with a multilingual premium of +25 to +40% per added language. The real challenge is not technical (hreflang is standard) but editorial: professional translation at EUR 0.12-0.20/word sells, while auto-translation destroys credibility with a demanding DACH audience. Planning translation governance from the RFP stage avoids timeline drift (9 to 13 weeks).
The language-by-language quote in 2026
Multilingual adds three line items: translation, language integration and international SEO setup (hreflang, per-language sitemaps). The table below breaks down a base language then each added language.
| Line item | 2026 range (EUR) | Detail |
|---|---|---|
| Base site EN (12 pages) | 6,000 - 10,000 | Design, integration, EN SEO |
| Professional DE translation | 900 - 1,700 | EUR 0.12-0.20/word, ~7,000 words |
| Professional NL translation | 1,000 - 1,900 | slightly higher NL rate |
| Integration 2 languages | 1,200 - 2,800 | templates, menus, content |
| International SEO (hreflang) | 700 - 1,600 | tags, sitemaps, Search Console |
| Trilingual 12-page total | 9,500 - 19,000 | By depth |
The per-language premium therefore lands around 25 to 40% of the single-language budget once translation and integration are added. For a dense product catalog, plan the high end: word volume explodes.
Professional translation vs auto-translation
The temptation of auto-translation (AI plugin) is strong, but with a DACH audience, linguistic quality drives trust. Here is the real trade-off.
| Criterion | Auto-translation (AI/plugin) | Professional translation |
|---|---|---|
| 2026 cost | EUR 0 - 500/year | EUR 0.12 - 0.20/word |
| Perceived DACH quality | average to poor | native |
| Industry terminology | approximate | mastered |
| Credibility risk | high | low |
| Local SEO (DE keywords) | weak | optimized |
| Update maintenance | automatic | via glossary/TM |
| Fit for premium B2B | no | yes |
Common 2026 compromise: professional translation for strategic pages (offers, references, contact) and reviewed AI assistance for high-volume blog content. A translation memory (TM) and industry glossary cut the cost of future updates.
Mini case study
Julien, export director of a components SME in Amsterdam, wants to open Germany and Austria. He orders an EN/DE/NL 12-page site at EUR 14,500, including EUR 3,100 of professional translation and EUR 1,300 of international SEO. Goal: capture German-speaking industrial buyers. Six months later, the site generates 6 qualified requests/month from the DACH region; at an average order of EUR 45,000 and a 20% close rate, a single German order per quarter repays the multilingual premium and funds the base language for the rest of the world.

FAQ
What premium should we plan for a multilingual site in 2026?
From +25 to +40% per added language, translation and integration included. A trilingual 12-page site sits between EUR 9,500 and 19,000.
How much does professional translation cost?
Between EUR 0.12 and 0.20 per word, German being slightly pricier than English. For ~7,000 words per language, allow EUR 900 to 1,900.
Is hreflang really necessary?
Yes: it tells Google which version to serve by language and country. Misconfigured, it creates duplicate content and disperses your ranking.
Can we use auto-translation to cut the budget?
For a premium B2B DACH audience, not on strategic pages: linguistic quality drives trust. A mixed model (pro on key pages, reviewed AI on the blog) is a good compromise.
What timeline for a trilingual site?
From 9 to 13 weeks. Translation and per-language validation loops stretch the schedule most; a glossary approved upfront speeds everything.
