The verdict in three sentences
For a 400-member trade association in Berlin, rebuilding an institutional website with a members' area costs between 18,000 and 45,000 EUR excluding VAT in 2026, depending on the depth of the directory, gated content and integrations (CRM, membership, events). A headless CMS with a two-level approval workflow and accessibility compliance (BITV 2.0 in Germany, RGAA in France, both aligned with WCAG 2.1 AA) are no longer optional for a representative body. Plan 4 to 6 months from a tender with at least 3 agencies to launch.
Functional building blocks and their cost
An association website serves three audiences: members (services, documents, regulatory watch), non-members to recruit, and institutions (ministries, press, elected officials). Each audience requires distinct building blocks, which shape the quote.
| Building block | Description | 2026 budget (EUR excl. VAT) |
|---|---|---|
| Institutional core | 25 to 40 pages, branding, news, press | 7,000 to 12,000 |
| Members' area | Login, gated documents, profiles | 4,000 to 10,000 |
| Member directory | Search by trade, region, certification | 2,500 to 7,000 |
| Regulatory watch | Legal briefs, email alerts, archive | 2,000 to 5,000 |
| Two-level approval workflow | Editor, then director general, then publish | 1,500 to 3,500 |
| Accessibility audit and fixes | Audit, fixes, accessibility statement | 2,500 to 5,500 |
| CRM or membership tool connector | Sync of dues and member status | 3,000 to 8,000 |
An association limited to the core, members' area and directory lands around 18,000 to 25,000 EUR. With regulatory watch, a CRM connector and online dues payment, the budget rises to 35,000 to 45,000 EUR.
Headless CMS, accessibility, hosting: the structural choices
A headless CMS (Sanity, Strapi, Directus) separates content management from display. For an association the benefit is twofold: a precise approval chain (the communications officer drafts, the director general or legal team approves) and fast pages that are easier to make accessible.
| Criterion | Classic WordPress | Headless CMS | SaaS association platform |
|---|---|---|---|
| Upfront cost | 12,000 to 25,000 EUR | 18,000 to 45,000 EUR | 3,000 to 8,000 EUR |
| Subscription or hosting | 30 to 80 EUR/month | 60 to 150 EUR/month | 150 to 600 EUR/month |
| Approval workflow | Plugin, limited | Native, multi-level | Variable |
| Achievable accessibility compliance | Medium, theme-dependent | High | Low to medium |
| Security attack surface | High (plugins) | Low | Vendor-dependent |
| Data portability | Good | Very good | Often poor |
Local EU hosting (OVH, Scaleway, Hetzner, IONOS) costs about 60 EUR per month for this type of site, backups included. It simplifies GDPR compliance, especially since the directory and members' area process personal data. On accessibility, public-service bodies must publish an accessibility statement, and the European Accessibility Act extends obligations to many private actors from 2025. Targeting 75 % compliant criteria at launch is realistic.
Running a tender with 3 agencies
The board often requires competitive bidding. A well-prepared tender narrows the gap between quotes, which can vary threefold when the brief is vague.
| Step | Duration | Deliverable |
|---|---|---|
| Internal scoping and content inventory | 3 to 4 weeks | 10 to 15 page brief |
| Tender to 3 to 5 agencies | 3 weeks | Priced proposals |
| Pitches and selection | 2 weeks | Agency chosen, contract |
| UX design and mock-ups | 4 to 5 weeks | Approved mock-ups |
| Development and CMS integration | 7 to 9 weeks | Site in acceptance testing |
| Content migration, accessibility audit, training | 3 to 4 weeks | Launch |
In the brief, specify the number of members, access profiles, the volume of documents to migrate (often 300 to 1,500 files), the approval chain and the existing membership tool. Ask for pricing per building block to compare like for like.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, director general of a 400-company association in Berlin, selects a 32,000 EUR project: core, members' area, directory, regulatory watch, two-level workflow and accessibility audit. Hosting at 60 EUR per month and maintenance at 250 EUR per month, so 3,720 EUR per year.
Four-year cost: 32,000 + 14,880 = 46,880 EUR, about 29 EUR per member per year. Meanwhile, the directory and document area cut email and phone requests by about 6 hours per week for the permanent staff, 300 hours a year. If the association retains 8 more members a year thanks to more visible services, at an average 1,200 EUR in dues, it recovers 9,600 EUR a year.
FAQ
What budget should a trade association plan for its website?
Between 18,000 and 45,000 EUR excluding VAT in 2026 for 400 members, depending on the members' area, directory and integrations. Add 3,000 to 5,000 EUR per year for hosting and maintenance.
Why consult at least 3 agencies?
Boards often require it, and it lets you compare technical approaches. With a precise brief, the gap between quotes usually shrinks to 20 to 30 %.
Is accessibility compliance mandatory for an association?
It is if the association performs a public-service mission or falls under the European Accessibility Act. Even without an obligation, an audit from 2,500 EUR protects the organisation's reputation.
Can we collect membership dues online?
Yes, via Stripe or an existing membership tool, for 3,000 to 8,000 EUR depending on the sync. Transaction fees run around 1.5 % + 0.25 EUR per European card payment.
How long does the project take?
Count 4 to 6 months, including 2 months of scoping and tendering. Content migration remains the most underestimated step.
