The verdict in three sentences
For a consulting firm in Amsterdam that bids on public and donor-funded tenders, the website is a credibility asset checked by evaluators and consortium leads before the shortlist. A bilingual EN/NL site with a case base, expert profiles and publications costs EUR 12,000 to 35,000, for 6 to 10 weeks of work. One won assignment, typically EUR 100,000 to 500,000, repays the investment many times over, and the same logic holds in Cotonou where a comparable site costs 800,000 to 2,200,000 FCFA.
What a consulting firm website costs in Amsterdam in 2026
| Package (2026 order of magnitude) | Content | Price excl. VAT | Timeline |
|---|---|---|---|
| Essential | 8 to 10 pages EN, expertise areas, contact | EUR 12,000 to 16,000 | 5 to 6 weeks |
| Tender-ready | EN/NL, base of 20 to 50 filterable cases | EUR 17,000 to 25,000 | 6 to 8 weeks |
| Consortium | Tender-ready + expert profiles, publications, partner area | EUR 25,000 to 35,000 | 8 to 10 weeks |
| Writing and translating case sheets | 30 to 60 sheets | EUR 4,000 to 9,000 | In parallel |
| Hosting, domain, backups | Per year | EUR 600 to 1,800 | 1 day |
| Maintenance and case updates | Per month | EUR 300 to 900 | Ongoing |
For comparison, a Cotonou firm pays 800,000 to 2,200,000 FCFA (about EUR 1,200 to 3,350) for an equivalent bilingual FR/EN scope. The most underestimated item everywhere is writing case sheets. Evaluators want the client or funder, country, duration, value and deliverables: a wall of logos is not enough.
What evaluators and consortium leads look for
| Site element | What the evaluator checks | Recommended format |
|---|---|---|
| Case references | Similar experience over 5 to 10 years | One sheet per assignment: funder, country, value, period, role |
| Filters by sector and funder | Speed to find 3 relevant references | Filters for health, agriculture, governance, World Bank, EU |
| Key expert profiles | Qualifications and years of experience | Short online profile, full CV on request |
| Publications and studies | Analytical capacity | PDF summaries, 2 to 4 pages each |
| Second language | Readability for local and international clients | Professional translation, not machine output |
| Governance and compliance | Seriousness of the firm | KvK number, anti-corruption policy, GDPR notice |
A consortium lead assembling a bid spends 5 to 10 minutes on average assessing a potential partner. If your site lets them find three comparable assignments in under two minutes, you are in the conversation.

Pieter, partner at a 15-consultant evaluation firm in Amsterdam, bids on 25 tenders a year with a 12 % win rate, so 3 assignments. He invests EUR 22,000 in a bilingual site with 40 filterable cases, plus EUR 500 a month of maintenance. Over one year, total cost reaches EUR 28,000. With his references now visible, he is invited into two additional consortia and wins one more assignment worth EUR 180,000. The return is more than 6 times the annual investment.
FAQ
Can assignment values be published?
Yes if the contract allows it, which is the case for most World Bank or EU-funded contracts whose awards are already public. For private clients, show a range, for example EUR 100,000 to 250,000.
Is a Dutch version really needed?
Yes if you target Dutch ministries, municipalities or corporates. It accounts for 20 to 30 % of the content budget and doubles your visibility with local buyers.
How many references should be published at launch?
Aim for at least 20 complete sheets, ideally 30 to 60 over 10 years. Below 15, the site weakens your bid more than it helps.
Should expert CVs be online?
Publish a short profile with areas and years of experience, and keep the full CV in funder format on request. This protects personal data under GDPR.
