The verdict in three sentences
In 2026, a corporate site redesign of 15 to 35 pages for a B2B manufacturer in Berlin costs between EUR 12,000 and 28,000. Multilingual DE/EN/FR adds roughly 25 % to the budget, and the product catalogue with PDF datasheets is the most underestimated line item. The real risk is not design but SEO migration: mishandled, it can wipe out years of industrial ranking.
The redesign line items in detail
A CFO decides on numbers, not mockups. Here is the 2026 breakdown for a B2B industrial corporate site (order of magnitude, Berlin agency pricing).
| Line item | 2026 range (EUR) | Note |
|---|---|---|
| Discovery + audit | 1,500 - 3,000 | Traffic analysis + IA |
| Corporate UI design | 3,000 - 6,000 | Brand, mockups, components |
| Product catalogue + PDF sheets | 3,000 - 7,000 | Templates, filters, downloads |
| CMS build (15-35 pages) | 3,000 - 6,500 | Editable back office |
| Multilingual DE/EN/FR (+25 %) | 2,500 - 5,000 | hreflang + translations |
| SEO migration + redirects | 1,500 - 3,000 | 301 redirect plan |
| Total redesign | 12,000 - 28,000 | By scope |
The 3-year total cost of ownership includes maintenance and hosting, which a CFO must provision for.
| Recurring item | 2026 cost | Over 3 years |
|---|---|---|
| Maintenance | EUR 200 - 400/month | EUR 7,200 - 14,400 |
| Hosting + EU CDN | EUR 50 - 90/month | EUR 1,800 - 3,240 |
| Additional translations | EUR 0.12/word | Variable |
| Annual security audit | EUR 800 - 1,500/year | EUR 2,400 - 4,500 |
Redesign or new CMS: how to decide
The central question: reuse the existing platform or start fresh? The answer depends on the CMS age and technical debt.
| Criterion | Redesign on current CMS | New headless CMS |
|---|---|---|
| 2026 cost | EUR 12,000 - 18,000 | EUR 18,000 - 28,000 |
| Timeline | 8 - 10 wks | 10 - 14 wks |
| SEO migration risk | Low | Medium (managed) |
| Scalability | Limited | High |
| ERP/CRM integration | Hard | Native |
If the CMS is over 6 years old or blocks ERP integration, a new headless foundation pays off over 3 years despite a higher entry ticket.
Mini case study
Anja, CFO of a 60-employee Berlin manufacturer (EUR 12M revenue), leads the redesign of a 28-page site with a 140-SKU catalogue. Committed budget: EUR 21,000, including EUR 4,200 for DE/EN/FR targeting French clients. The SEO migration is scoped: over 3 months organic traffic dips only 4 % before climbing (+18 % at 6 months). With EUR 300/month maintenance, the 3-year total cost reaches EUR 31,800, or 0.26 % of annual revenue.

FAQ
Why does multilingual cost 25 % more?
Because you must structure hreflang, duplicate each template, integrate translations and test each language. For DE/EN/FR, budget EUR 2,500 to 5,000 extra.
How do we avoid losing SEO traffic?
A thorough 301 redirect plan, keeping high-performing URLs, and 90 days of Search Console monitoring. Budget EUR 1,500 to 3,000 for this phase.
Are PDF datasheets really a big line item?
Yes: templates, automatic generation, filters and tracked downloads represent EUR 3,000 to 7,000 depending on SKU count.
What timeline for a manufacturer?
Between 10 and 14 weeks for a redesign with catalogue and multilingual, discovery included.
What maintenance budget should we provision?
