The verdict in three sentences
An engineering consultancy in Amsterdam invests between 6,000 and 14,000 EUR in 2026 for a site that establishes credibility with large accounts. The winning strategy rests on sector reference pages and downloadable technical documentation (a lead magnet) that captures qualified contacts. Cost per B2B lead runs 50 to 150 EUR, for tenders worth tens of thousands of euros.
A technical B2B site, not a brochure
In engineering, the buying decision involves several stakeholders (technical management, procurement, IT). The site must demonstrate competence through proof: quantified case studies, sector references, methodology, certifications. The lead magnet (white paper, technical note) turns an anonymous visitor into a qualified contact.
| Service | 2026 range (EUR) | Timeline |
|---|---|---|
| B2B expertise site | 6,000 - 14,000 | 6-10 weeks |
| Reference / sector pages | 350 - 700 / page | in package |
| Lead magnet (white paper + landing) | 1,500 - 4,000 | 2-3 weeks |
| Marketing automation (setup) | 1,200 - 3,500 | 1-2 weeks |
| Technical B2B SEO (6 months) | 4,200 - 10,000 | ongoing |
| Maintenance + hosting / year | 700 - 2,000 | annual |
The lead magnet plus marketing automation pairing is the real engine: without it, a beautiful site remains a catalogue that generates no contacts.
Large-account acquisition: the numbers
In technical B2B, quality beats quantity. Expert content and long-tail SEO on precise queries ("structural engineering consultancy Amsterdam") capture decision-makers. 2026 orders of magnitude:
| Metric | 2026 range | Note |
|---|---|---|
| Cost per qualified B2B lead | 50 - 150 EUR | by sector |
| White-paper conversion rate | 8 - 15 % | visitors -> leads |
| Lead -> sales meeting rate | 20 - 35 % | with nurturing |
| Meeting -> tender access rate | 25 - 40 % | long cycle |
| Average contract value | 20,000 - 250,000 EUR | highly variable |
| Sales cycle length | 3 - 9 months | multiple decision-makers |
Mini case study
Thomas, director of a 22-person thermal engineering consultancy in Amsterdam, invests 12,000 EUR in an expertise site with three sector pages and a white paper, plus 700 EUR/month of B2B SEO and marketing automation. After eight months the site generates 22 qualified leads/month at an average 95 EUR cost. With 30% converting to meetings and 30% reaching a tender, that is about 2 tenders/month. If just one every two months wins an 80,000 EUR contract, the annual budget (about 20,400 EUR) is recouped on the first signed contract.
