The verdict in three sentences
A bilingual FR/EN site costs +25 to +45 % more than a monolingual one in 2026, on a base of 900,000 to 2,500,000 FCFA equivalent. The surcharge comes from professional translation (0.08 to 0.15 EUR/word), hreflang tag management and +2 to 3 weeks of lead time. Architected well, this site ranks in both languages and opens export markets without doubling maintenance.
What an FR/EN site really costs in 2026
Multilingual isn't just translation: it's architecture, international SEO and doubled maintenance. Here are the 2026 ranges for a Toronto firm targeting both language markets.
| Item | 2026 cost | Detail |
|---|---|---|
| Monolingual base site | 900,000 - 2,500,000 FCFA | B2B site 8-15 pages |
| Multilingual surcharge | +25 to +45 % | Architecture, hreflang, UI |
| Pro translation (per word) | 0.08 - 0.15 EUR | Human, reviewed, sector-specific |
| Translation of 8,000 words | 640 - 1,200 EUR | Full brochure site |
| Bilingual maintenance | +30 to 50 % | Dual content kept current |
| Hreflang + sitemap setup | 200,000 - 500,000 FCFA | Technical SEO config |
Machine translation alone is discouraged in B2B export: a sector-specific human review avoids the mistranslations that cost credibility with international buyers.
Subdomain vs subfolder: which architecture
The architecture choice drives international SEO and maintenance. Here's the 2026 comparison of the three approaches.
| Criterion | Subfolder (/fr/) | Subdomain (fr.) | ccTLD domain (.ca) |
|---|---|---|---|
| SEO authority | Shared (strong) | Diluted | Separate |
| Setup cost | Low | Medium | High |
| Hreflang management | Simple | Medium | Complex |
| Maintenance | Single site | 2 spaces | 2 sites |
| Recommended for | Most SMEs | Distinct brands | Large groups |
| Extra lead time | +2 weeks | +2-3 weeks | +4-6 weeks |
For an exporting SME, the subfolder /fr/ is almost always the best choice: it concentrates domain authority, simplifies hreflang and avoids maintaining two separate sites. A Toronto firm targeting both French and English North American markets applies the same subfolder logic in CAD/EUR.

Mini case study
Aminata runs a B2B agri-export SME selling processed goods across Europe and North America. She budgets a base of 1,800,000 FCFA plus +38 % multilingual surcharge, i.e. ~2,484,000 FCFA, with 9,000 words translated at 0.12 EUR/word (~1,080 EUR). Six months later, the /fr/ version generates 34 % of export quote requests and two signed international contracts. The ~684,000 FCFA surcharge is recouped on the first export contract alone, whose margin far exceeds the multilingual investment.
FAQ
Subdomain or subfolder for SEO? The /fr/ subfolder concentrates the main domain's authority and ranks faster. The subdomain suits cases where the two brands are distinct or run by separate teams.
Is hreflang essential? Yes, to avoid duplicate content and serve the right language to the right user. A bad hreflang config makes the FR page rank on EN queries, or vice versa.
Can I auto-translate? For a first draft yes, but sector-specific human review is essential in B2B export. Count 0.08 to 0.15 EUR/word for reviewed professional translation.
How much extra time for bilingual? Count +2 to 3 weeks: translation, integration, hreflang config and QA in both languages.
Does maintenance double? Almost: every content update must exist in both languages. Plan +30 to 50 % on the annual maintenance budget.
