The verdict in three sentences
For a Dublin mid-market firm exporting into the DACH region, a multilingual EN/DE/FR site costs 30 to 50% more than a single-language site in 2026, most of the premium coming from translation and i18n management. Professional B2B translation runs €0.12 to €0.18 per word, and a polished German version (not a Google Translate) generates +22% export leads on average. The technical point not to miss is hreflang: misconfigured, it sinks your SEO instead of lifting it.
What an extra language really costs
An added language isn't just translating text: it's a duplicated tree, hreflang management, per-version testing, and often cultural adaptation (Germany: formal, reference and standards oriented; English-speaking world: benefit oriented). The technical cost of an i18n foundation (well-integrated next-intl vs a hacked plugin) is paid once but shapes the whole project.
| Item per added language | Cost 2026 | Basis |
|---|---|---|
| Pro translation (15,000 words) | €1,800 – €2,700 | €0.12–0.18/word |
| i18n integration | €1,200 – €2,500 | Setup + tests |
| UI adaptation (RTL, dates, formats) | €400 – €900 | By complexity |
| Native proofreading | €350 – €600 | Quality control |
| Local SEO (keywords, hreflang) | €600 – €1,200 | Per market |
Technical approaches: next-intl vs plugin
The choice of i18n layer determines maintenance cost over 3 years. A clean foundation costs more upfront but avoids debt.
| Criterion | next-intl (bespoke) | CMS plugin |
|---|---|---|
| Upfront cost | €1,500 – €3,000 | €300 – €800 |
| Performance | Excellent | Variable |
| SEO hreflang | Native, clean | Often fragile |
| Adding a language | Fast | Laborious |
| Technical debt | Low | High |
| Suited to | Serious export firm | Small test site |

Sarah is marketing manager at a 90-person industrial mid-market firm near Dublin, exporting equipment to Germany and Austria. Her site is in English only. She adds DE and FR for €9,800 (translation 30,000 words at €0.15/word = €4,500, i18n and integration €3,800, local SEO €1,500). Before, the site generated 18 export leads/month from German-speaking visitors tolerating an English site. After the native DE version, leads rise to 22/month (+22%). With an average export deal of €25,000 and an 8% win rate, those +4 leads/month represent about €8,000 of additional monthly revenue: payback in 5 weeks.
FAQ
Why not use free machine translation? Because in B2B DACH, rough translation destroys credibility and therefore conversion. A German client instantly spots non-native text; the cost of pro translation is the project's best ROI.
What is hreflang and why is it critical? It's the tag telling Google which version to serve by language and country. Misconfigured, it creates duplicate content and sinks SEO; done right, each market gets the correct page.
How many words does a showcase site have to translate? A mid-market showcase site typically runs 12,000 to 30,000 words. At €0.12–0.18/word, translating one language costs €1,800 to €5,400.
Should I translate the whole site or a selection? Start with commercial and product pages, add the rest later. Translating 100% upfront only helps if every page has an export role.
next-intl or plugin for a mid-market firm? For a firm serious about export, next-intl: clean SEO, performance and easy language addition. A plugin is only justified for a small, short-lived test site.
