The verdict in three sentences
A regional trade association with 600 members should budget EUR 18,000 to 32,000 for an institutional website with a member area, directory and events calendar in 2026. The specification moves the price more than the design does: SSO, WCAG 2.1 AA accessibility and EU hosting are the three lines to settle before the tender. Also budget EUR 250 to 450 a month of support, or the member area will feel dated within a year.
The budget line by line
An association website combines a public side (mission, news, policy positions, directory) and a private side (restricted documents, regulatory updates, event registration). Here is the 2026 order of magnitude for a 600-member organisation.
| Work package | 2026 range | What drives the price |
|---|---|---|
| Scoping, workshops and wireframes | EUR 3,000 to 5,000 | Number of committees consulted |
| Public site, 25 to 40 pages | EUR 5,000 to 9,000 | Templates, sections, languages |
| Member area (documents, updates, profile) | EUR 4,000 to 8,000 | Permission levels, CRM import |
| Member company directory | EUR 2,000 to 4,000 | Trade filters, map, certifications |
| Events calendar and registration | EUR 1,500 to 3,000 | Online payment, quotas |
| WCAG AA audit and remediation | EUR 2,500 to 3,000 | Number of templates audited |
| Core total | EUR 18,000 to 32,000 | 12 to 20 weeks |
| Option: headless CMS + member SSO | +EUR 4,000 | Existing identity directory |
What the specification must decide
A vague tender produces incomparable bids, from EUR 12,000 to 60,000 for the same need. Five decisions make offers comparable.
| Topic | Budget option | Robust option | Budget impact |
|---|---|---|---|
| CMS | Classic WordPress | Headless CMS (Strapi, Sanity) + Next.js front end | +EUR 3,000 to 6,000 |
| Authentication | Local accounts | SSO linked to the member CRM | +EUR 4,000 |
| Hosting | Shared EU, EUR 40 a month | Dedicated OVH or Scaleway, EUR 120 a month | +EUR 960 a year |
| Accessibility | Good practice | WCAG 2.1 AA audit and statement | +EUR 2,500 to 3,000 |
| Support | EUR 250 a month, 2 h | EUR 450 a month, 4 h and on-call | +EUR 2,400 a year |
| Editorial workflow | 1 level | Approval by the director general | +EUR 800 to 1,500 |
Hosting in the European Union with OVH or Scaleway simplifies GDPR compliance for member data. Accessibility is not always a legal requirement for a private association, but it often becomes one through public funding, and it serves the image of the profession.
A typical tender calendar
Allow 3 weeks to write the specification, 4 weeks of consultation, 2 weeks of pitches and 12 to 20 weeks of delivery. Launching in January allows go-live before a June general assembly.
Mini case study
Jan, director general of a construction trade association, selects a EUR 26,000 bid with SSO (+EUR 4,000), Scaleway hosting at EUR 80 a month and support at EUR 350 a month. Three-year cost: EUR 30,000 + 2,880 + 12,600 = EUR 45,480, or EUR 25 per member per year. By moving registration for 20 annual events and circular distribution online, the team saves about 6 hours a week, close to 300 hours a year.

FAQ
Is EUR 18,000 a realistic budget?
Yes for a polished public site, a simple member area and a directory without a map. Beyond two permission levels or SSO, plan for EUR 25,000 to 32,000.
Does an association need a headless CMS?
It becomes useful if you also feed an app or several regional sites. For a single site, a well-maintained WordPress is enough and saves EUR 3,000 to 6,000.
What does EU hosting cost?
Between EUR 40 and 120 a month with OVH or Scaleway depending on traffic and redundancy. For 600 members, a EUR 60 to 80 plan is comfortable.
What does EUR 250 to 450 a month of support cover?
Security updates, backups, fixes and 2 to 4 hours of improvements. On-call cover before major events pushes the package toward EUR 450.
How long from tender to launch?
Allow 5 to 7 months in total, including 12 to 20 weeks of delivery after selecting the vendor.
