The verdict in three sentences
A chamber of commerce website rebuild sits in 2026 within a range of EUR 40,000 to 90,000 excl. tax, excluding application maintenance. The specification that produces comparable bids requires WCAG 2.1 AA accessibility (RGAA 4.1 in France, the equivalent standards in Quebec), sovereign hosting and a 3-year maintenance contract priced separately. Plan for 3 to 5 months of procedure before the first design workshop, or the new site will land after your annual general meeting.
A realistic budget for a chamber website tender
A chamber of commerce, trades or agriculture runs a dense site: member directory, training calendar, formalities, economic news, elected members' areas. The budget depends mostly on the number of templates, the connectors and content migration.
| Tender item | 2026 range (EUR excl. tax) | Comment |
|---|---|---|
| UX design and user workshops | 6,000 to 12,000 | 4 to 6 workshops, business and founder personas |
| Design and digital guidelines | 5,000 to 10,000 | 15 to 25 responsive templates |
| CMS development and integration | 18,000 to 40,000 | Drupal, WordPress or headless depending on IT |
| Connectors (training calendar, CRM, payment) | 4,000 to 12,000 | Existing APIs or scheduled exports |
| Content migration | 3,000 to 8,000 | 300 to 1,200 pages to sort |
| Accessibility audit and statement | 2,500 to 5,000 | Initial audit and re-audit |
| Contributor training | 1,500 to 3,000 | 2 to 3 sessions |
| Total rebuild | 40,000 to 90,000 | Excluding maintenance |
Maintenance is priced separately: EUR 8,000 to 15,000 excl. tax per year, or EUR 24,000 to 45,000 over 3 years. Isolate it in a separate lot or optional tranche so bid comparison stays readable.
Scoring criteria that select a real provider
The most common weighting in 2026 for this kind of tender is 60% technical merit, 40% price. Technical merit must be split into measurable sub-criteria, otherwise scoring becomes open to challenge.
| Technical sub-criterion | Suggested weight | Evidence expected in the bid |
|---|---|---|
| Methodology and schedule | 15% | Detailed backward schedule, acceptance milestones |
| Accessibility WCAG AA | 12% | Audit method, certified profiles |
| UX and design quality | 12% | Comparable public references |
| Architecture and security | 10% | Technical diagram, update policy |
| Sovereign hosting and reversibility | 6% | Local data centre, exit plan |
| Eco-design | 5% | Target page weight, planned measures |
| Price | 40% | Completed price schedule and cost estimate |
Two points often make the difference. First, require a limited mock-up or prototype from shortlisted bidders, with a stipend of EUR 1,500 to 3,000: you judge real work rather than a written statement. Second, require a priced reversibility plan, so you do not depend on the incumbent when maintenance ends.
The timeline of a simplified procedure
| Step | Indicative duration |
|---|---|
| Drafting the specification and market sourcing | 4 to 6 weeks |
| Publication and response period | 4 to 5 weeks |
| Analysis, interviews, negotiation | 3 to 4 weeks |
| Award notice and standstill period | 2 to 3 weeks |
| Total before kick-off | 3 to 5 months |
Above EUR 90,000 over the full contract duration (maintenance included), check the applicable publication thresholds with your legal team: 3 years of maintenance can push the estimated value into a higher publication category.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sophie, communications manager at a chamber of commerce, prepares a tender for a 650-page site. Estimate: rebuild EUR 68,000, maintenance EUR 11,000 per year over 3 years, for a total of EUR 101,000 excl. tax. By isolating content migration (EUR 6,500) and asking bidders to archive 40% of obsolete pages, she cuts the scope to 390 pages and saves about EUR 2,600. The reversibility criterion mostly spares her a migration cost estimated at EUR 15,000 in 2029.
FAQ
Is WCAG AA accessibility mandatory for a chamber of commerce?
Public bodies are generally subject to digital accessibility obligations, with a published statement and a multi-year plan. Budget EUR 2,500 to 5,000 for the initial audit and re-audit.
Should the specification impose a specific CMS?
It is better to describe functional needs and IT constraints, then let bidders propose. Imposing a CMS often reduces the number of bids by 30 to 50%.
How do you avoid an abnormally low bid?
Ask for a detailed cost estimate in days per profile. A bid below EUR 35,000 for a site of more than 500 pages should be justified in writing.
What does sovereign hosting mean here?
Hosting operated within your jurisdiction by a provider not subject to extraterritorial laws. The extra cost compared with a generalist cloud remains moderate, EUR 50 to 150 per month.
Can Kolonell bid on a public tender?
Yes, alone or in a consortium, with a technical statement, references and an integrated accessibility audit. We can also help upstream during market sourcing.
