The verdict in three sentences
For a trade federation of 1,200 member companies in Dublin, a membership SaaS at 3,000 to 12,000 EUR a year covers 80 % of needs from month one. A custom portal, at 35,000 to 80,000 EUR on the Irish market, only pays off after 4 to 5 years, unless your dues rules, directory or integration with the public website are genuinely specific. The decision rests on three criteria: complexity of the dues scale, weight of history to migrate, and the need for SSO with the public site.
What a member area really needs
The chief executive of a federation usually expects six functions: dues invoicing and payment, a member directory searchable by trade and county, members-only documents (legal notes, sector agreements, research), registration for webinars and AGMs, a segmented newsletter, and engagement statistics for the board.
| Function | Membership SaaS 2026 | Custom portal |
|---|---|---|
| Dues | Flat or banded scale, card and direct debit | Any scale: headcount, turnover, membership class, pro rata |
| Directory | Standard profiles, limited filters | Trade filters, map, exports for committees |
| Members-only documents | Folders by membership tier | Fine-grained rights by committee, branch or role |
| Webinars | Zoom or Teams integration | Replays, attendance certificates, CPD credits |
| SSO with public site | Often missing or paid add-on | Single sign-on across site and member area |
| History migration | CSV import of active members | 10 years of dues, roles, correspondence |
| Statistics | Predefined dashboards | Custom indicators for the board |
The five-year cost calculation
The right metric is total cost over five years, not the entry price. Figures below are 2026 market estimates for an organisation with 1,200 members.
| Item | Entry SaaS | Premium SaaS | Custom (low range) | Custom (high range) |
|---|---|---|---|---|
| Setup | 1,500 EUR | 5,000 EUR | 35,000 EUR | 80,000 EUR |
| Annual subscription or maintenance | 3,000 EUR | 12,000 EUR | 5,000 EUR | 10,000 EUR |
| History migration | 1,000 EUR | 3,000 EUR | included | included |
| Annual hosting | included | included | 1,200 EUR | 2,400 EUR |
| Total over 5 years | 17,500 EUR | 68,000 EUR | 66,000 EUR | 142,000 EUR |
Against a premium SaaS at 12,000 EUR a year, a 35,000 EUR custom build becomes cheaper in year five. Against an entry SaaS, custom never catches up. Custom is justified when it generates revenue or savings the SaaS cannot: a complex dues scale that avoids billing errors, a directory monetised with partners, or accredited training with certificates.
As a benchmark, Kolonell's 2026 grid for a medium-complexity custom application is 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), with maintenance at 75,000 to 120,000 FCFA per month (110 to 180 EUR).
Migration and SSO: the two items that blow budgets
Migrating ten years of history means cleaning duplicate companies, linking departed contacts, converting successive dues scales and preserving the record of board and committee roles. Budget 10 to 20 days of work, so 5,000 to 12,000 EUR in a custom project. SSO with the public website removes a second password and clearly lifts member area usage: it is often the criterion that tips the decision towards custom, since few membership SaaS products do it cleanly.

Aoife, chief executive of a construction trade federation in Dublin, manages 1,200 members paying an average of 900 EUR, so 1,080,000 EUR in annual dues. Her scale combines headcount, turnover and membership class, and produces about 4 % of invoices corrected by credit note, so 43,200 EUR re-invoiced and 120 hours of admin work a year. A 50,000 EUR custom portal, with 7,500 EUR a year of maintenance and hosting, brings errors under 1 % and saves 90 hours (3,150 EUR at 35 EUR an hour). If the reliable scale cuts unrecovered dues after corrections by 10,000 EUR a year, the annual gain reaches 13,150 EUR, or 5,650 EUR net of running costs: break-even comes in just under 9 years against doing nothing, but against a premium SaaS at 12,000 EUR a year that cannot handle this scale, the annual difference reaches 17,650 EUR (subscription avoided + business gains - running costs) and break-even drops to just under 3 years.
FAQ
How much does a member portal for a trade federation cost in 2026?
A membership SaaS costs 3,000 to 12,000 EUR a year for 1,200 members. A custom portal costs 35,000 to 80,000 EUR, plus 6,000 to 12,500 EUR a year of maintenance and hosting.
When does custom pay off?
Against a premium SaaS, break-even sits around 4 to 5 years. Against an entry SaaS, you need measurable business gains (dues errors, partner revenue) to justify it.
Can we migrate ten years of dues history?
Yes, with 10 to 20 days of data cleaning and conversion. Most SaaS tools only import active members, losing the history of roles and arrears.
Is SSO with our public website essential?
Not mandatory, but single sign-on often raises member area usage by 20 to 40 %. Budget 3,000 to 6,000 EUR to add it to an existing site.
How long does a custom portal take?
Usually 4 to 6 months, including one month of data migration and three weeks of acceptance testing with a panel of 20 members.
