The verdict in three sentences
For a Berlin strategy consultancy competing for Mittelstand and corporate mandates, the website is a thought leadership platform that buyers read before they ever call. A budget of 15,000 to 45,000 EUR net is reasonable if it funds content first: 10 to 20 case studies, insight articles published every month and clear partner profiles. Design matters less than proof, and page speed matters more than animation.
What buyers check online
A procurement lead or managing director comparing 5 consultancies spends a few minutes on each site. They look for specific answers: comparable projects, industries, team seniority, and a point of view on their problem. The table ranks credibility elements by observed impact in 2026, as orders of magnitude.
| Credibility element | Impact on shortlisting | Production effort | Indicative market cost |
|---|---|---|---|
| 10 to 20 case studies (industry, scope, result) | Very high | 2 to 4 h per case | 3,000 to 8,000 EUR of copy |
| Partner and consultant profiles | High | 1 h per profile | 1,000 to 2,500 EUR |
| Insight articles (1 per month) | High over time | 6 to 10 h per article | 600 to 1,200 EUR per article |
| English version alongside German | High for international clients | 15 to 25 pages | 3,000 to 7,000 EUR |
| Client logos (with consent) | Medium | Low | included |
| Impressum, GDPR notice, memberships | Medium, reassuring | Low | included |
Case studies are the best return. A structured case (context, client sector, duration, approach, quantified outcome) answers the same questions a buyer asks in a pitch meeting.

Speed and consistency, two underrated criteria
Many decision makers first open your site on a phone between meetings. A 6 MB homepage with autoplay video takes several seconds even on German 4G in a train. A realistic target is under 1 MB per page, WebP or AVIF images, a CDN and full load under 2 seconds. Case studies should be downloadable as light PDFs under 500 KB for internal circulation.
Consistency with your proposals matters too: the same project names, figures and dates must appear on the site and in your pitch decks. An inconsistency spotted by a buyer costs more than an average design.
German law adds specific requirements: a complete Impressum, a GDPR compliant privacy notice and a cookie banner that allows refusal as easily as consent. Missing items can trigger warning letters (Abmahnungen) costing several hundred euros each.

Katrin, partner at a strategy consultancy in Berlin, submits 20 proposals a year. Her shortlist rate is 25%, giving 5 shortlists, and she wins 40% of those, or 2 mandates per year averaging 180,000 EUR.
She invests 28,000 EUR in a site with 15 case studies and an insights hub, plus 400 EUR per month of maintenance: 32,800 EUR in year one. If her shortlist rate rises to 30%, she reaches 6 shortlists and, at the same win rate, 2.4 mandates. The average gain of 0.4 mandate equals 72,000 EUR of revenue. At a 30% margin, that is 21,600 EUR in year one, and the site keeps working in year two at maintenance cost only, so payback arrives within about 20 months.
FAQ
How many case studies should be live at launch?
Aim for at least 10, spread across industries. Beyond 15, add filters by sector and service so a buyer finds a comparable project in under 30 seconds.
German, English or both?
Both if you serve international groups or foreign owned subsidiaries. Translate home, services, cases and team first, typically 15 to 25 pages.
Can we publish project budgets?
Only with client consent. A range, such as 100,000 to 250,000 EUR, is often enough to show capacity.
How long does a consulting firm website take?
Plan 5 to 8 weeks, of which 2 to 3 go into writing case studies. Content remains the main source of delay.
How often should we publish insights?
One article a month is enough to show a living practice. After 12 months, 12 articles of 1,200 words form a reference library that supports both sales and search.
