The verdict in three sentences
A bilingual B2B website (EN/FR) in Toronto runs between EUR 12,000 and EUR 28,000 in 2026, excluding translation. Each additional language adds EUR 900 to 2,400 in development plus recurring editorial cost. The line item that blows budgets is never design: it is misconfigured hreflang and unmaintained translation.
What each language really costs
A language cost splits into three distinct blocks that quotes often merge: the technical foundation (i18n structure, routing, hreflang), content translation, and yearly editorial maintenance. Here are 2026 orders of magnitude for a Toronto B2B site of 15 to 30 pages.
| Item | 2026 cost (EUR) | Recurrence |
|---|---|---|
| Technical i18n foundation (2 languages) | 3,500 - 7,000 | One-time |
| Additional language (dev + routing) | 900 - 2,400 | Per language |
| Pro B2B translation (per word) | 0.12 - 0.22 | By volume |
| Translating 20 pages (~9,000 words) | 1,100 - 2,000 | Per language |
| Editorial maintenance / language / year | 1,500 - 4,000 | Annual |
| Hreflang audit + international SEO | 1,200 - 3,500 | One-off |
A three-language site (EN/FR/ES) therefore typically costs EUR 16,000 - 34,000 in year one, then EUR 4,500 - 12,000/year in editorial and SEO maintenance if you want the versions to stay alive.
Where the budget really goes
The breakdown surprises marketing directors. Design and integration matter less than multilingual logic and international SEO, which drive the real export ROI.
| Item | Share of total budget | Business impact |
|---|---|---|
| Design + UX | 18 - 25 % | Brand image |
| Front-end integration | 20 - 28 % | Performance |
| i18n foundation + hreflang | 15 - 22 % | Export visibility |
| Initial translation | 10 - 18 % | Credibility |
| International SEO | 12 - 20 % | Qualified traffic |
| QA + multilingual testing | 6 - 10 % | Reliability |
The three costliest mistakes in 2026: translating with an automatic plugin without review (instant B2B credibility loss), skipping hreflang tags (Google serves the wrong language and bounce rate climbs 15 to 30 %), and budgeting no recurring editorial effort (EN/ES versions die within 8 months).

A 20-page bilingual B2B site ships in 7 to 11 weeks in Toronto in 2026: 2 weeks of scoping and multilingual architecture, 3 to 4 weeks of design and integration, 2 weeks of translation and editorial integration, 1 to 2 weeks of multilingual QA and SEO. Each additional language adds 1 to 2 weeks once the source content is stable.
Mini case study
Mathieu, sales director of a Toronto precision-machining SME exporting to the US and UK, aims for 25 % international revenue by 2027. Three-language site (EN/FR/ES), 24 pages: i18n foundation EUR 5,500, design + integration EUR 11,000, EN + ES translation EUR 3,600, international SEO EUR 4,200, i.e. EUR 24,300 for the build. With an average B2B deal of EUR 18,000 and an export site generating 6 qualified leads/month of which 1 closes, the site pays back in under 2 months of margin. The editorial maintenance (EUR 6,500/year) is covered by a single yearly deal.
FAQ
What does one extra language really cost? Count EUR 900 to 2,400 in development plus EUR 1,100 to 2,000 of translation for 20 pages, plus EUR 1,500 to 4,000/year of maintenance. The trap is the recurring cost, not the setup.
Subdomain, subdirectory or .ca/.de? For export B2B, the subdirectory (/en/, /es/) offers the best cost/SEO ratio in 2026: it pools domain authority and costs 30 to 50 % less than a fleet of ccTLDs.
Is machine translation enough? Not for B2B: raw DeepL reaches 70 - 85 % quality, but the remaining 15 - 30 % (industry jargon, CTAs, legal notices) destroys credibility. Budget human post-editing at EUR 0.06 - 0.10/word.
How long to become internationally visible? On niche B2B keywords, count 4 to 8 months post-launch with an international SEO budget of EUR 800 to 2,000/month to see regular organic leads.
Can we start bilingual and add languages later? Yes, if the i18n foundation is laid from the start. Adding a language onto an unprepared base costs 2 to 3 times more than a planned addition.
