The verdict in three sentences
For a sector federation with 420 member companies, a trilingual corporate website costs between EUR 16,700 and 29,600 excl. VAT in 2026. The third language version (+20 %) and the members' area with online dues (+EUR 5,550) make the difference between a brochure and a genuine member service tool. With a 12-week lead time, the project fits neatly into a launch before the annual general meeting.
The detailed budget
An employers' federation speaks to three audiences: its members, public authorities and international partners. Its website must serve all three, in their language, with a finish that reflects the sector's weight.
| Item | 2026 price (EUR excl. VAT) | Comment |
|---|---|---|
| Corporate site FR/EN, 20 to 30 pages | 16,700 to 29,600 | Mission, governance, committees, publications, news, events |
| Dutch version | + 20 % | Professional translation, validated terminology |
| Members' area with online dues | + 5,550 | Secure login, card or bank payment, automatic receipts |
| Filterable member directory | 2,300 to 4,200 | Search by activity, city, size, certification |
| Built-in newsletter | 750 to 1,400 | Sign-up, members and non-members segmentation |
| Events and registration module | 1,400 to 2,800 | AGM, training, trade fairs, badges |
| Maintenance and hosting | 230 to 420 per month | Updates, security, backups, support |
For a typical project (25-page site, trilingual, members' area, directory, newsletter), the ballpark is EUR 30,500 to 44,400 excl. VAT.
Three project levels based on your priorities
| Level | Goal | Content | Budget (EUR excl. VAT) | Lead time |
|---|---|---|---|---|
| Corporate | Image and advocacy | 20 pages FR/EN, publications, news | 16,700 to 20,400 | 8 weeks |
| Trilingual corporate | Reach Flemish authorities and media | 25 pages FR/NL/EN | 21,300 to 26,900 | 10 weeks |
| Members' platform | Member services and dues | Trilingual, members' area, directory, events | 32,400 to 44,400 | 12 weeks |
| Approval workflow option | Editorial governance | Writer, reviewer, secretary general sign-off | 1,850 to 3,250 | 2 weeks |
| Accessibility audit option | Compliance and image | WCAG 2.1 AA audit, fixes | 1,400 to 2,300 | 2 weeks |
The approval workflow is often underestimated: in a federation, a position statement published without board approval can cause an incident. A writer, reviewer, secretary general chain removes that risk.
What the members' area changes for the secretariat
In many federations, chasing membership dues ties up one person for several weeks a year: calls, letters, bank reconciliations. A members' area lets members pay online, download their membership certificate and invoice, and update their directory listing.
The filterable directory itself becomes a reason to join: visibility to contractors, public buyers and foreign partners looking for a qualified Belgian supplier. Member data protection must comply with GDPR and the Belgian Data Protection Authority's guidance, with a record of processing activities.
Mini case study
Pieter, secretary general of a Brussels sector federation with 420 members, collects average dues of EUR 555, so EUR 233,100 a year. The collection rate caps at 78 % and chasing payments takes an assistant about 300 hours a year.

He picks the Members' platform at EUR 37,000 excl. VAT and EUR 325 of monthly maintenance. If online payment and automatic reminders lift collection to 86 %, he recovers 8 points, or EUR 18,650 a year, plus about 200 hours freed up. The project pays back in about two and a half years, maintenance included, before counting new memberships generated by the directory.
