The verdict in three sentences
In Brussels, a management consultancy website built by a local agency costs, as a 2026 ballpark, between 10 000 and 40 000 EUR, and more for a trilingual firm with a client area. Kolonell builds the expertise pages, case studies and partner profiles for a fixed price of 2 700, 4 500 or 8 200 EUR, delivered in 3 to 4 weeks on Starter and Growth. The real comparison is the 3-year total cost, the copywriting (the backbone of a consulting site) and how languages are handled in a city that works in French, English and Dutch.
This version is written for the English-speaking partners of management consultancies in Brussels, many of whom work with EU institutions, international federations and multinational clients.
What do Brussels agencies, freelancers and Kolonell charge?
The ranges below are prudent ballparks, not official figures. They draw on public rate cards of agencies in the Brussels-Capital Region, minimum project sizes listed on Clutch.co profiles, hourly rates published by Belgian agencies (often 85 to 140 EUR per hour) and rates visible on Malt.
| Criterion | Brussels agency | Local freelancer | Kolonell |
|---|---|---|---|
| Build cost, 2026 ballpark | 10 000 to 40 000 EUR | 3 000 to 10 000 EUR | 2 700 / 4 500 / 8 200 EUR, fixed |
| Changes outside scope | Often 85 to 140 EUR per hour | Often 60 to 95 EUR per hour | Quoted before any work |
| Usual timeline | 8 to 14 weeks | 5 to 10 weeks | 3 to 4 weeks, Premium usually 4 to 6 |
| Expertise and case study copy | Often billed separately or left to the firm | Rarely included | Native French or English included |
| Dutch version | Often offered | Depends on the profile | Supplied by the firm or quoted separately |
| Support after launch | Separate maintenance contract | Case by case | 3 months, 6 on Premium |
| Ownership | Check the contract | Check the contract | Domain in your name, all access handed over |
Payment is by bank transfer or Wise: 50 % to start, 50 % at delivery. A project manager works in your time zone, with Google Meet calls at your time and a written update every week. The team is based in Senegal (GMT), one to two hours behind Brussels depending on the season. Kolonell does no in-person meetings and no on-site photo shoots: partner portraits come from you or a Brussels photographer. Full details are on our international website offer.
Which 3-year total cost should you compare?
A consultancy keeps its site alive: new case studies, publications, new partners. The table assumes the same maintenance budget on both sides, since Kolonell maintenance after the support period is quoted on request.
| Item over 36 months | Brussels agency (mid range) | Kolonell Premium |
|---|---|---|
| Bilingual FR/EN site build | 24 000 EUR | 8 200 EUR |
| Support included after launch | Depends on contract | 6 months included |
| Maintenance (same assumption) | 150 EUR per month over 30 months, 4 500 EUR | 4 500 EUR, maintenance quoted on request |
| Dutch translation of key pages | Often 1 800 EUR | Translator chosen by the firm or quoted separately, assumption 1 800 EUR |
| 8 case studies added over 3 years | 16 hours at 110 EUR, 1 760 EUR | Quoted beforehand, assumption 1 400 EUR |
| Partner portraits | 900 EUR | Local photographer booked separately, 900 EUR |
| Indicative total | 32 960 EUR | 16 800 EUR |
These figures structure the comparison; they do not predict your invoice. Ask every supplier to fill in the same table.
What does each Kolonell tier include for a consultancy?
| Item | Starter 2 700 EUR | Growth 4 500 EUR | Premium 8 200 EUR |
|---|---|---|---|
| Expertise pages | Main offers (strategy, transformation, organisation) | One page per expertise or sector | Full structure by expertise and sector |
| Case studies | 3 cases presented | Reusable template, up to 8 cases at launch | Library filterable by sector |
| Partner profiles | Team page | One profile per partner | Detailed profiles, publications, languages |
| Publications and briefing notes | No | Articles section | Articles section with categories |
| Bilingual FR/EN site | No | No | Included |
| Timeline | 3 to 4 weeks | 3 to 4 weeks | Written schedule at kickoff, usually 4 to 6 weeks |
| Support after launch | 3 months | 3 months | 6 months |
A client extranet for sharing deliverables, or a custom recruitment portal, is an application quoted on request. So is ongoing search work.
What does a Brussels consultancy website need?
Brussels is home to firms working for EU institutions, professional federations, regional administrations and multinationals based between the European Quarter, Avenue Louise and Diegem. Buyers (strategy directors, public procurement officers, secretaries general of federations) visit the site before a first call or while assessing a bid. The site should:
- Show precise expertise rather than a generic list of services.
- Present anonymised case studies when your contracts require confidentiality: context, mission, type of outcome, without naming the client unless they agree in writing.
- Feature the partners: background, sectors, working languages.
- Handle languages: French and English first, Dutch for Flemish clients and Brussels administrations.
- Recruit: a clear careers page for junior and experienced consultants.
On compliance, the facts only. GDPR applies to contact and application forms, overseen by the Belgian Data Protection Authority (APD/GBA): privacy policy, cookie consent, retention period for CVs. If your firm carries out interest representation towards EU institutions, registration in the EU Transparency Register can be mentioned. WCAG 2.1 AA is the technical reference for accessibility. This is not legal advice.

How do you compare quotes, and which red flags matter?
- A quote with no copywriting: a consulting site without strong texts stays empty for months, because partners lack time.
- A price without a written scope: ask for the list of pages, the number of case studies and the languages.
- A domain registered in the agency's name: it must be in yours.
- Client logos displayed without consent: check your contracts before publishing anything.
- An automatic Dutch version not reviewed by a translator.
- Mandatory long-term maintenance with no way to take back control.
Mini case study
Illustrative example. Pierre V., managing partner of a 12-consultant firm specialised in transforming professional federations, receives two proposals. A Brussels agency quotes 21 000 EUR for an FR/EN/NL site, in 12 weeks, copywriting not included. Kolonell proposes Premium at 8 200 EUR for a written bilingual FR/EN site, delivered on a written 5-week schedule; the Dutch version goes to the firm's usual translator for 1 800 EUR.
Total: 21 000 EUR versus 10 000 EUR, an 11 000 EUR gap, not counting partner days saved on writing. At the internal day rate of 1 000 EUR that Pierre uses, five days of writing avoided are worth another 5 000 EUR.
