The verdict in three sentences
The redesign of an industrial catalogue site into a B2B lead generator costs between EUR 9,000 and EUR 22,000 in 2026 in Berlin, depending on the number of product sheets and the complexity of the technical catalogue. The number-one risk factor is the SEO migration: without a rigorous 301-redirect plan, the redesign crashes organic traffic. The strategic trade-off is between a big-bang redesign (fast, risky) and a phased redesign (spread out, safer).
Budget by catalogue size
A manufacturing SME needs a site that reassures professional buyers and eases contact. The technical catalogue is the core of the project.
| Scope | 2026 price (EUR) | Timeline | Product sheets |
|---|---|---|---|
| Brochure + light catalogue | 9,000 - 13,000 | 8-10 weeks | < 50 |
| Technical catalogue redesign | 13,000 - 18,000 | 10-12 weeks | 50-200 |
| Redesign + configurator / RFQ | 18,000 - 22,000 | 12-14 weeks | 200+ |
| SEO migration (301, content) | +2,000 - 5,000 | +2-3 weeks | - |
| Export multilingual | +3,000 - 7,000 | +2-4 weeks | - |
The configurator or request-for-quote (RFQ) form is the major conversion lever for industry: it turns a visitor into a qualified lead with a precise specification.
Phased versus big-bang redesign
Two migration strategies exist. The big-bang switches everything at once: fast but risky for SEO and operations. The phased redesign migrates in batches: longer, but it protects traffic and spreads internal load.
| Criterion | Big-bang | Phased |
|---|---|---|
| Total timeline | 8-12 weeks | 4-8 months |
| SEO risk | High | Controlled |
| Overall cost (EUR) | 9,000 - 18,000 | 12,000 - 24,000 |
| LCP target (Core Web Vitals) | < 2.5s | < 2.5s |
| Traffic interruption | Possible | Minimal |
| Internal team load | Concentrated | Spread |
For an SME whose organic traffic already generates leads, the phased redesign protects the existing SEO asset. The big-bang suits a site that is technically obsolete and poorly ranked.
Mini case study
Claire, CFO of a 60-employee manufacturing SME in Berlin, is choosing between a big-bang redesign at EUR 15,000 and a phased redesign at EUR 20,000. The current site generates 12 quote requests/month with an LCP of 4.8s. A redesign targeting LCP < 2.5s and an optimised RFQ form aims for +40% conversion, so 17 requests/month. At a 20% conversion rate and an average order of EUR 9,000, the 5 extra requests/month produce 1 more order, or EUR 9,000 of added monthly revenue. The EUR 20,000 phased redesign pays back in about 2.5 months of extra orders, while preserving rankings.

FAQ
How much does an industrial site redesign cost in Berlin in 2026?
Between EUR 9,000 and EUR 22,000 depending on catalogue size and whether there is a configurator. The catalogue and RFQ are the structural line items.
Why is SEO migration so critical?
Without an exhaustive 301-redirect plan, a redesign can lose 30 to 60% of organic traffic within weeks. A EUR 2,000-5,000 migration budget is an insurance investment.
What are Core Web Vitals and why target LCP < 2.5s?
They are Google's performance metrics. An LCP below 2.5s improves ranking and reduces bounce rate, especially on mobile.
Phased or big-bang: which should I choose?
If your site already generates leads via SEO, the phased approach protects the asset. If the site is obsolete and poorly ranked, the big-bang is faster and cheaper.
What maintenance budget should I plan after the redesign?
Maintenance of EUR 250 to 600/month covers security, catalogue updates, performance monitoring and minor enhancements.
