The verdict in three sentences
For an engineering firm, the website is a technical proof tool: you do not buy aesthetics, you buy the credibility that wins tenders. In 2026, expect 9,000 to 20,000 EUR for a 12 to 20-page brochure site with project references and technical documents, versus 16,000 to 32,000 EUR for a site with a secure client document portal. The right scope depends on your need to share confidential deliverables with clients.
Brochure site vs site + client document portal
The question is not graphic but functional: settle for a reference brochure site or add a secure area where clients download drawings, reports and deliverables. Here is the comparison.
| Criterion | Reference brochure site | Site + document portal |
|---|---|---|
| Price (EUR) | 9,000 - 20,000 | 16,000 - 32,000 |
| Pages / sections | 12 - 20 | 12 - 20 + portal |
| Public technical documents | Yes | Yes |
| Secure client area | No | Yes (authentication) |
| Deliverable sharing | No | Yes, traceable |
| Timeline | 8 - 12 weeks | 14 - 20 weeks |
| Best if | Reputation and SEO | Tooled client relationship |
For most engineering firms, the reference brochure site is enough to feed the pipeline; the document portal is justified when sharing deliverables becomes a recurring irritant.
2026 price structure
Here is the breakdown of a typical Amsterdam project, as a 2026 order of magnitude, for a 12 to 20-page site showcasing technical expertise.
| Item | Amount (EUR) |
|---|---|
| UX design + expertise tree | 1,800 - 3,500 |
| Development 12-20 pages | 3,200 - 6,800 |
| Project reference pages | 1,500 - 3,800 |
| Technical document library | 1,000 - 2,900 |
| Niche B2B SEO + content | 1,500 - 3,000 |
| Total | 9,000 - 20,000 |
Project reference pages are the conversion core: a well-documented project (context, constraints, solution, quantified results) is worth ten pages of institutional talk.

Mini case study
Philippe, head of an Amsterdam engineering firm specialising in structures, hesitated between a 13,000 EUR brochure site and a 26,000 EUR site with a document portal. He started with the brochure site. Within six months, niche B2B SEO lifted the firm on queries like structural engineering firm Amsterdam, generating 22 qualified inbound requests. At a 25% conversion rate and an average engagement of 18,000 EUR, that is roughly 5 extra engagements over the year, over 90,000 EUR; the 13,000 EUR investment pays back with the first engagement won.
FAQ
How much does an engineering firm website cost in 2026? Expect 9,000 to 20,000 EUR for a 12 to 20-page brochure site; adding a secure client document portal raises the budget to 16,000 - 32,000 EUR.
Is a client document portal useful? It is when sharing drawings and reports becomes recurring and sensitive; otherwise, a reference brochure site is enough to feed the commercial pipeline.
What niche SEO budget should I plan? Niche B2B SEO costs 800 to 2,000 EUR/month; it targets low-volume, high-intent technical queries that are very profitable in B2B.
What timeline should I expect? A reference brochure site ships in 8 to 12 weeks; adding a secure document portal adds 4 to 8 weeks.
Are reference pages worth the effort? Yes: they are what converts in technical B2B; a quantified project page (timeline, budget, result) reassures more than a generic pitch.
