The verdict in three sentences
A multilingual export site does not cost double just because it has two languages: the technical base is shared, and it is professional translation, integration and per-market SEO that add up. As a 2026 order of magnitude, budget 8,000 EUR for the base language, then 2,200 to 3,500 EUR per added language and 600 EUR/month of SEO per target country. The real question is not the site price but the return per market: a language that generates no export pipeline is a cost, not an investment.
The real cost, language by language
The classic trap is believing a DE/EN/FR site costs three times a single-language site. In reality, the next-intl architecture, design system and components are written once. What repeats is translated content, per-locale QA and market-specific SEO.
| Item | Base DE | + English | + French |
|---|---|---|---|
| Design and design system | 8,000 EUR | included | included |
| Pro translation (native, ~6,000 words) | — | 900 EUR | 1,100 EUR |
| Integration + locale QA | — | 800 EUR | 900 EUR |
| Hreflang + per-language sitemap | — | 500 EUR | 500 EUR |
| On-page SEO per market | — | 700 EUR/mo | 700 EUR/mo |
| Subtotal per added language | — | 2,200 EUR | 2,500 EUR |
A full DE/EN/FR site therefore lands around 12,700 to 14,000 EUR to build, excluding acquisition campaigns. Timeline extends by roughly two weeks per language: translation, native review, then per-locale QA.
What makes the difference on export
A badly configured hreflang or unreviewed machine translation costs more in credibility than in euros. Three trade-offs shape the budget.
| Technical choice | Budget option | Serious export option |
|---|---|---|
| Translation | AI + light review | Native industry translator |
| URL structure | /en/ subfolder | subfolder + full hreflang |
| SEO | translated keywords | local keyword research per country |
| Content | mirror of base | adapted to market habits |
| Indicative cost/language | 1,400 EUR | 2,500-3,500 EUR |
To sell to French buyers, local keyword research (not a plain translation of German keywords) changes everything: B2B search intent differs from one country to another.
Mini case study
Marc, head of a Berlin food SME, already exports to France via trade shows. He wants a DE/EN/FR site to capture inbound leads. Build budget: 8,000 + 2,200 + 2,500 = 12,700 EUR, plus 1,400 EUR/month of SEO across two markets. An average French distributor contract yields 18,000 EUR of annual margin. He only needs one distributor signed through the site within 12 months for the operation to pay off handsomely; break-even is reached in the first quarter of a successful sales cycle.

FAQ
Do I really need a native translator rather than AI?
For B2B export content, yes: a register or technical-term error undermines credibility with a professional buyer. Budget 0.10 to 0.14 EUR/word for a native specialised translator; reviewed AI can work for secondary pages.
Is hreflang essential?
Yes, as soon as you have the same language on several markets or multiple languages. Without hreflang, Google may serve the wrong version and dilute your ranking. It is a 500 EUR item per language, non-negotiable.
How long to add a third language later?
With a clean next-intl architecture from day one, about two weeks: translation, integration, QA, hreflang. The avoided extra cost is huge compared with a rebuild.
Is per-market SEO required every month?
No, but without it the site stays invisible. A budget of 600-700 EUR/month per country over 6-12 months is the minimum to install durable positions on export keywords.
Can we start DE/EN then add French?
It is even recommended: validate the model on an English-speaking market, measure pipeline, then invest in the third language once the first market pays. The architecture allows it with no technical debt.
