The verdict in three sentences
For a chain of 3 to 15 gyms in London or Dubai, the real issue is not the software price but the churn rate, which runs between 30 and 45% a year. Off-the-shelf club software costs EUR 150 to 400 per club per month and is enough while you stay under 4 clubs with a standard offer. Beyond that, a custom application at EUR 35,000-70,000 (about USD 38,000-76,000) pays for itself as soon as you gain 2 to 3 retention points, because each point is worth tens of thousands in recurring revenue.
Club software, custom or hybrid: the 2026 numbers
Independent chains in London and Dubai compete with budget operators at GBP 20-30 or AED 150-250 a month. Their edge is service, group classes and member relationships. Yet most club software is built for a single site: clunky multi-site handling, rigid reports, little automation on inactivity.
| Criterion | Off-the-shelf club software | Custom application | Hybrid (software + custom modules) |
|---|---|---|---|
| Upfront cost | EUR 0 to 3,000 setup | EUR 35,000 to 70,000 | EUR 12,000 to 25,000 |
| Recurring cost (6 clubs) | EUR 900 to 2,400 per month | EUR 400 to 900 per month (hosting, maintenance) | EUR 1,200 to 2,800 per month |
| 5-year total cost (6 clubs) | EUR 54,000 to 147,000 | EUR 59,000 to 124,000 | EUR 84,000 to 193,000 |
| Direct debit (Bacs, SEPA, cards) | Yes, via an imposed partner | Yes, provider of your choice (GoCardless, Stripe, bank) | Depends on software |
| Multi-club access control | Often limited to approved hardware | Badge, QR code or app, any brand | Partial |
| Inactive member alerts | Basic or missing | Scenarios at 7, 14, 21 days without a visit | Possible via API |
| Data ownership | Export sometimes charged | Full | Shared |
| Go-live time | 2 to 6 weeks | 3 to 5 months | 6 to 10 weeks |
Custom is not more expensive over 5 years from 6 clubs upward. It becomes clearly competitive at 10 clubs, where off-the-shelf subscriptions often exceed EUR 3,500 a month.
What a well-designed chain application contains
A useful scope fits into six modules. The rest can wait.
| Module | Key functions | Share of budget | Expected impact |
|---|---|---|---|
| Memberships and contracts | Plans, 12-month commitment, freeze, transfer between clubs | 18% | Fewer billing errors |
| Direct debit | Electronic mandates, rejections, automatic re-presentation | 15% | Failed payments down from 4-6% to 2-3% |
| Access control | QR code in the app, badge, existing turnstiles | 17% | No more card-sharing fraud |
| Class booking | Schedule, waiting list, reminder 2 h before | 16% | Class fill rate up 10 to 15% |
| Retention | Inactivity alerts, coach follow-up, reactivation offer | 20% | 2 to 5 fewer churn points |
| Chain dashboard | Revenue per club, churn, hourly attendance | 14% | Data-backed decisions on openings and hours |
The retention module is the one that pays for the project. A member who has not visited for 14 days is, according to the chains we observe, 3 to 4 times more likely to cancel within 90 days. A personalised coach follow-up at day 10 wins back a significant share of them.
The value of one retention point
Take an average fee of EUR 39 a month, or EUR 468 a year. With 5,000 members, one retention point means 50 members kept, so EUR 23,400 in annual revenue. With 12,000 members, the same point is worth EUR 56,000. These are 2026 orders of magnitude, to be recalculated with your actual prices.
Mini case study
James runs a chain of 6 gyms across London with 5,200 members and 38% annual churn. He pays the equivalent of EUR 2,100 a month for his current software, or EUR 25,200 a year. The custom project is quoted at EUR 52,000, plus EUR 700 a month for maintenance and hosting (EUR 8,400 a year).

Target: move from 38% to 34% churn, i.e. 4 points. Gain: 208 members kept x EUR 468 = EUR 97,344 in revenue per year. Saving on software subscription: 25,200 - 8,400 = EUR 16,800 a year. Payback: 52,000 / (97,344 + 16,800) = roughly 5.5 months after go-live. Even with only a 2-point gain, the project pays back in under a year.
FAQ
How long does it take to build a gym chain application?
Allow 3 to 5 months from scoping to production, including 4 to 6 weeks of testing in a pilot club. Contract and direct debit mandate migration happens over a weekend, with no interruption to collections.
Can we keep our current turnstiles and badge readers?
Yes in 80% of cases, if the hardware exposes a standard interface (Wiegand, relay or API). Otherwise, a control box costs EUR 300 to 600 per entrance.
Are existing direct debit mandates kept?
Yes, mandate references and your creditor identifier remain valid. Members have nothing to re-sign, which avoids a wave of 5 to 10% opportunistic cancellations.
Is the application GDPR compliant?
It is hosted in the UK, the EU or the UAE as required, with a processing register, defined retention (for example 3 years after contract end) and data export on request within 30 days.
What budget for a limited first version?
A V1 with memberships, direct debit, QR access and inactivity alerts starts around EUR 35,000 for 3 clubs. Class booking and advanced reporting are added afterwards for EUR 10,000 to 20,000.
