The verdict in three sentences
A rebuild of an 8-to-15-page B2B corporate site costs between 9,000 and 18,000 EUR in 2026 for an Amsterdam SME, before options. Custom design (+4,000 to 7,000 EUR) and headless CMS integration on Next.js (3,500 to 6,000 EUR) are the two line items that can double a quote. Budget 8 to 12 weeks, a 30-40% deposit, and 90 to 250 EUR/month of maintenance to protect the investment.
The line-by-line price grid (2026)
A credible quote itemizes every line. A flat "rebuild, 12,000 EUR" with no breakdown is a red flag: you cannot make trade-offs.
| Line item | 2026 range (EUR) | Note |
|---|---|---|
| Discovery & sitemap | 1,200 - 2,500 | Workshops, wireframes, content plan |
| UI design (adapted template) | 2,500 - 4,500 | Applied brand, 4-6 key mockups |
| Custom design | +4,000 - 7,000 | Dedicated art direction |
| Headless CMS integration | 3,500 - 6,000 | Next.js + Sanity/Strapi |
| Copywriting & on-page SEO | 1,800 - 3,500 | 10-15 optimized pages |
| QA & go-live | 900 - 1,800 | Testing, 301 redirects, GDPR |
| Standard rebuild total | 9,000 - 18,000 | Excludes custom |
Add VAT and keep an 8-10% reserve for out-of-scope requests.
Agency vs studio: what the model changes
The vendor choice shifts the cost structure as much as the final figure.
| Criterion | Full-service agency | Studio / collective | Senior freelancer |
|---|---|---|---|
| Typical rebuild budget | 14,000 - 25,000 | 9,000 - 16,000 | 6,000 - 12,000 |
| Indicative day rate (EUR) | 550 - 800 | 450 - 650 | 350 - 550 |
| Average timeline | 10-14 wks | 8-12 wks | 8-16 wks |
| Dedicated PM | Yes | Sometimes | No |
| Dependency risk | Low | Medium | High |
| Included maintenance | 3-6 months | 1-3 months | Negotiable |
A hybrid studio often offers the best ratio for an SME: real project management without the overhead of a large agency.
Mini case study
Sarah, COO of a precision-engineering SME in Amsterdam-Noord (28 staff), rebuilds her 2018 site. Chosen quote: 13,500 EUR (discovery 2,000, adapted design 3,800, Next.js integration 5,200, copy/SEO 2,500). Deposit 40% = 5,400 EUR at kickoff. Over 12 months the site generates 9 qualified quote requests/month versus 3 before: at a 20% close rate and a 22,000 EUR average deal, the investment pays back on the second signed contract.

FAQ
How much does a B2B rebuild cost in Amsterdam in 2026?
Between 9,000 and 18,000 EUR for an 8-to-15-page corporate site, and 18,000 to 30,000 EUR with custom design and CRM integration.
What deposit do agencies ask for?
Usually 30-40% at signing, an interim payment at mockup approval, and the balance at go-live.
How long does the project take?
8 to 12 weeks for a standard rebuild; add 2 to 4 weeks if EN/local content is not ready.
Is a maintenance contract necessary?

Often partially. Budget 1,800 to 3,500 EUR for rework/SEO rewriting: that is what moves the organic-traffic needle.
