The verdict in three sentences
A premium, fully custom redesign for a B2B SME in Berlin costs between 8,000 and 18,000 EUR in 2026 for 10 to 15 pages, against 2,500 EUR for a plain Webflow template. The real lever is not page count but the conversion lift: projects migrated to Next.js gain on average +40% in qualified enquiries. Budget 6 to 10 weeks of production and prefer a fixed price over a day rate to cap your exposure.
What the budget actually covers
A premium redesign is not a coat of paint: it reworks architecture, content, SEO and performance. Here is the typical split of a 12,000 EUR budget in 2026.
| Line item | Share of budget | Range EUR | Deliverable |
|---|---|---|---|
| Strategy & UX (workshops, wireframes) | 15% | 1,200 - 2,700 | Sitemap, low-fi mockups |
| Custom design (UI, design system) | 25% | 2,000 - 4,500 | Figma mockups, tokens |
| Next.js development | 35% | 2,800 - 6,300 | Responsive site, animations |
| Content & on-page SEO | 12% | 960 - 2,160 | Copy, tags, schema |
| CMS integration & QA | 8% | 640 - 1,440 | Back office, testing |
| Launch & training | 5% | 400 - 900 | Deployment, docs |
Development dominates because custom Next.js guarantees Core Web Vitals above 90 and load times under 1.5 s, two factors directly tied to conversion.
Template, freelancer or agency: the comparison
The choice of provider swings the price by a factor of three. 2026 orders of magnitude for an equivalent premium corporate site.
| Option | Upfront cost | Timeline | SLA / maintenance | Expected conversion |
|---|---|---|---|---|
| Adapted Webflow template | 2,500 - 4,000 EUR | 2-3 wks | None guaranteed | Baseline (index 100) |
| Solo freelancer (day rate 450-650 EUR) | 6,000 - 10,000 EUR | 5-8 wks | Availability-based | +15 to +20% |
| Agency fixed-price custom | 8,000 - 18,000 EUR | 6-10 wks | Support 150-400 EUR/mo | +35 to +40% |
| International premium studio | 20,000 - 45,000 EUR | 10-16 wks | SLA 99.9% | +40 to +50% |
A senior designer's day rate in Berlin sits between 450 and 650 EUR in 2026; an agency fixed price converts that overrun risk into a commitment on outcomes, which reassures most SME owners.
Mini case study
Marc, owner of a 45-person industrial SME in Berlin, redesigns his 6-year-old website. Budget agreed: 12,500 EUR, agency fixed price, 8 weeks. Before the redesign the site produced 18 quote requests a month at a 1.1% conversion rate. After moving to Next.js and reworking the product pages, the rate climbs to 1.6% (+45%), i.e. 26 requests a month. With an average deal of 8,000 EUR and a 20% close rate, the 8 extra requests represent 12,800 EUR of additional monthly revenue: the investment pays back in under 5 weeks of added activity.

FAQ
Why does a premium site cost more than a 2,500 EUR template?
A template ships a frozen skin; premium reworks UX, SEO and performance. That technical foundation produces the +40% conversion lift, invisible on a template but decisive on revenue.
How long does a premium redesign really take?
Budget 6 to 10 weeks in 2026: 1-2 weeks of scoping, 2-3 of design, 3-4 of development, 1 of QA. A shorter timeline often signals a disguised template.
Is a fixed price safer than a day rate?
Yes for an SME: the fixed price caps the budget and shifts overrun risk to the agency. Day rates (450-650 EUR/day) suit a scope that is still moving.
What maintenance budget should I plan after launch?
A support contract runs 150 to 400 EUR/month: security updates, small changes, Core Web Vitals monitoring. Essential to hold the performance level over time.
Is Next.js worth the premium over WordPress?
For a conversion-focused premium site, yes: load time halved, better technical SEO and stronger security. The development premium is recouped within months through added leads.
