The verdict in three sentences
A custom member portal for a trade association in Berlin costs between EUR 22,000 and EUR 45,000 in 2026, with SSO, a member directory and online membership payment. Plan for 14 weeks and a maintenance budget of around EUR 900/month. The return shows mainly in membership automation and the service value members perceive.
The cost breakdown in 2026
A member portal centralizes an association's services: resources, directory, dues, events. Here are the 2026 order-of-magnitude ranges.
| Module | Function | Cost 2026 (EUR) |
|---|---|---|
| Member portal (core) | Accounts, SSO, dashboard | 22,000 - 45,000 |
| Member directory | Profiles, search, networking | 4,000 |
| Online membership payment | Direct debit, reminders, receipts | 3,500 |
| Document library | Guides, intelligence, replays | 5,000 |
| Events calendar and registration | Ticketing, quotas | 4,500 |
| SSO + private area | Single secure sign-on | 3,000 |
The core depends on the number of members and member types (individuals, companies, regional chapters). A Starter version at EUR 22,000 covers accounts, directory and documents; a full version at EUR 45,000 adds dues, events and chapter spaces.
Membership automation: the real gain
Manual dues management (reminders, collection, receipts) ties up admin time. Here is the estimated impact for an association of 1,200 members.
| Metric | Before (manual) | After (online) |
|---|---|---|
| Renewal rate | 82% | 91% |
| Average collection delay | 38 days | 6 days |
| Admin hours/month (dues) | 42 h | 12 h |
| Monthly admin cost (EUR 35/h) | EUR 1,470 | EUR 420 |
| Unpaid dues | 9% | 3% |
| Monthly admin saving | - | EUR 1,050 |
With renewal up from 82% to 91% on an average due of EUR 220, the association also secures around EUR 23,760 in additional dues per year (108 members x EUR 220).
Mini case study
Marc is director general of a 1,200-member trade association based in Berlin. Dues management ties up 42 hours/month and the unpaid rate reaches 9%. He invests EUR 34,000 in a member portal with online payment, directory and library.
Between EUR 1,050 in monthly admin savings (EUR 12,600/year) and EUR 23,760 in better-collected dues, the estimated annual gain approaches EUR 36,000. The portal pays back in under 14 months, including EUR 900/month maintenance.
