The verdict in three sentences
In 2026, in Ireland, a bespoke membership platform (subscriptions, events, member portal) runs EUR 35,000-90,000 over 12 to 18 weeks, with recurring payments and GDPR compliance. An all-in-one SaaS at EUR 200-800/month starts fast but often skims a commission on dues and constrains the member experience. For an association of 5,000 members, a build that lifts renewal from 70 % to 91 % (+30 %) pays for itself in a single season.
All-in-one SaaS or a bespoke platform: the 2026 numbers
A membership SaaS charges a subscription plus, often, a percentage of dues; custom removes that tax on growth.
| Criterion | All-in-one SaaS | Bespoke platform |
|---|---|---|
| Entry cost | 0 to 5,000 EUR (setup) | 35,000 to 90,000 EUR |
| Recurring cost | 2,400 to 9,600 EUR/year | maintenance 15-20% of build/year |
| Commission on dues | 0 to 3 % common | 0 % (excl. Stripe fees) |
| Time to go live | 3 to 8 weeks | 12 to 18 weeks |
| Personalised member portal | Limited to theme | Fully bespoke |
| Event management + ticketing | Standard | Bespoke |
| Ownership of member data | Constrained export | Open database |
What a 35,000-90,000 EUR build covers
Scope drives price. A 2026 order-of-magnitude breakdown for an association of 5,000 members.
| Module | Range EUR | Indicative time |
|---|---|---|
| Member portal + profiles + directory | 8,000 - 18,000 | 3-4 weeks |
| Subscriptions + recurring payments (Stripe) | 9,000 - 20,000 | 3-4 weeks |
| Events + ticketing + registrations | 8,000 - 19,000 | 3-4 weeks |
| Renewal reminders + automated emails | 5,000 - 12,000 | 2-3 weeks |
| Admin back-office + reporting | 6,000 - 15,000 | 2-3 weeks |
| EU hosting, GDPR, acceptance testing, migration | 4,000 - 9,000 | ongoing |
Annual maintenance runs 15 to 20 % of the build: on 60,000 EUR, budget 9,000 to 12,000 EUR/year. Compare that to 2,400-9,600 EUR/year of SaaS plus the commission on dues which, at 2 % on 500,000 EUR of dues, is already 10,000 EUR/year.

Mini case study
Aoife, director of a professional association in Dublin (5,000 members, average dues 120 EUR), runs a 70 % renewal rate for lack of automated reminders and an attractive member portal. She invests EUR 62,000 in a bespoke platform, plus 10,000 EUR/year maintenance. Lifting renewal from 70 % to 91 % (+30 %) recovers 1,050 members × 120 EUR = 126,000 EUR/year in dues. By removing the 2 % SaaS commission (10,000 EUR/year) and the 6,000 EUR subscription, the build pays for itself in under 6 months from the first renewal campaign.
FAQ
Isn't an all-in-one membership SaaS enough? For a small association, often yes. Custom makes sense from 3,000-5,000 members, when the commission on dues gets costly and the member portal needs to reflect your brand and specific workflows.
How do you handle recurring payments? Via Stripe Billing for SEPA/EU cards, with automatic retries on failed collections. Stripe fees (around 1.5 % + 0.25 EUR in the EU) are the only deductions, with no platform commission.
Realistic timeline? Budget 12 to 18 weeks, migrating the 5,000 existing members at the end and switching over during a quiet period to limit impact.
Does GDPR apply to member data? Yes, fully. EU hosting (Ireland, AWS eu-west-1), explicit consent, right to erasure and a processing register are built in from the design stage.
Can we start small? Yes. Many first launch the member portal + subscriptions at 20,000-35,000 EUR, measure the impact on renewals, then add event ticketing. That's the approach we recommend.
