The verdict in three sentences
A mid-market corporate website is not a big brochure site: it is a project of content governance, compliance and multilingual delivery. In Amsterdam in 2026, expect 18,000 to 45,000 EUR net for 25-40 pages with an editorial-workflow CMS, plus 200-400 EUR/month. The specification must impose measurable requirements: 99.9% SLA, Core Web Vitals > 90, WCAG accessibility.
What structures the budget
Cost depends on governance level, languages and integrations. Here are the 2026 tiers for a mid-market firm.
| Scope | Corporate standard | Corporate premium | Group/holding |
|---|---|---|---|
| Pages | 25-30 | 30-40 | 40+ multi-site |
| Languages | EN/NL | EN/NL/DE | 3+ languages |
| Editorial-workflow CMS | yes | yes + advanced roles | yes + multi-subsidiary |
| Integrations (CRM, HR) | 1-2 | 3-4 | unlimited |
| Price net | 18,000-25,000 EUR | 25,000-35,000 EUR | 35,000-45,000 EUR+ |
| Maintenance/month | 200-280 EUR | 280-350 EUR | 350-400 EUR+ |
| Timeline | 12-14 weeks | 14-16 weeks | 16-20 weeks |
The editorial workflow (multi-level approval before publishing) is what distinguishes a true corporate project from an inflated brochure site.
The clauses the specification must impose
A solid tender sets numeric requirements, not wishes. Here are the non-negotiable clauses in 2026.
| Requirement | Level required | Associated cost |
|---|---|---|
| Accessibility (WCAG) | AA (audit included) | 2,500-5,000 EUR |
| Availability (SLA) | 99.9% | included in premium hosting |
| Performance | Core Web Vitals > 90 | included in dev |
| Hosting | EU (GDPR) | 100-250 EUR/month |
| Security | CSP headers, audit | 1,500-3,000 EUR |
| Reversibility | full export guaranteed | contractual clause |
Without a costed accessibility clause, a listed firm exposes itself to reputational and legal risk: WCAG is no longer optional for large players.

Mini case study
Nathalie, communications director of a 250-employee mid-market firm in Amsterdam, compares two offers for a 32-page EN/NL site. Offer A: 22,000 EUR without WCAG audit. Offer B: 27,000 EUR with accessibility audit (4,000 EUR) and 99.9% SLA. An audit added later would cost 5,000 EUR plus site rework. Over 3 years with maintenance (300 EUR/month), offer B totals 37,800 EUR all-in, versus 34,800 EUR for offer A plus a late audit at ~9,000 EUR. She picks offer B, cheaper in reality and compliance-safe.
FAQ
