The verdict in three sentences
For a chain of 6 gyms and 9,000 members, in Montpellier or Miami, every point of monthly churn is worth hundreds of thousands a year. Off-the-shelf club software at 150-400 EUR per gym per month handles memberships and key cards, but rarely detects members who are drifting away early. Custom software at 45,000-100,000 EUR (about 49,000-108,000 USD), connected to recurring direct debit and QR code access control, pays for itself within months if it brings churn from 4% to 2.5%.
The calculation that justifies everything: churn
In Montpellier, low-cost chains at 20 to 30 EUR a month push independent networks towards 35-50 EUR plans with group classes and coaching. Miami shows the same split between 10-25 USD budget gyms and 50-90 USD boutique clubs. Average revenue holds, but loyalty is fragile: a member who has not checked in for 3 weeks is highly likely to cancel within 60 days.
| Indicator (9,000 members, 39 EUR average per month) | 4% churn | 2.5% churn |
|---|---|---|
| Departures per month | 360 | 225 |
| Departures per year | 4,320 | 2,700 |
| Average member lifetime | 25 months | 40 months |
| Customer lifetime value (39 EUR x lifetime) | 975 EUR | 1,560 EUR |
| New members needed to stay flat | 360 per month | 225 per month |
| Acquisition cost at 60 EUR per member | 259,200 EUR per year | 162,000 EUR per year |
Moving from 4% to 2.5% saves 97,200 EUR of acquisition spend per year and raises each member's value by 60%. The software must be designed around that goal.
Off-the-shelf or custom in 2026
Club software (Resamania, Deciplus, Virtuagym, Mindbody, ABC Glofox) is reliable for selling memberships and booking classes. Limits appear with several locations, multi-site plans and the need for fine-grained attendance analysis.
| Criterion | Off-the-shelf club software | Custom build by Kolonell |
|---|---|---|
| Entry cost | 1,000 to 5,000 EUR setup | 45,000 to 100,000 EUR |
| Recurring cost for 6 gyms | 10,800 to 28,800 EUR per year | maintenance 35,000 to 120,000 FCFA per month, about 640 to 2,200 EUR per year |
| Direct debit and failed payment recovery | yes | yes, with staged SMS and email reminders |
| QR or key card access control | yes, hardware often imposed | dynamic QR in the app, compatible with existing turnstiles |
| Multi-gym membership | varies | native, rules per plan |
| Churn risk score | rare | calculated nightly from attendance |
| Branded member app | paid add-on | included |
Over 4 years, software at 20,000 EUR a year costs 80,000 EUR. A custom build at 70,000 EUR plus 6,000 EUR of maintenance totals 76,000 EUR, with anti-churn tools on top.
Built-in anti-churn levers
| Lever | Trigger | Observed effect (2026 order of magnitude) |
|---|---|---|
| Inactivity alert | 14 days without a check-in | 20 to 30% of inactive members return after a coach call |
| Online membership freeze | cancellation request | 25% choose a freeze instead of leaving |
| Staged failed payment recovery | rejected direct debit | 70% of arrears recovered in 15 days |
| Free coach review | 3rd month of membership | attendance up 15% |
| In-app referral | member active for 6 months | 8 to 12% of new sales |
| Per-gym dashboard | daily | churn comparison across sites |
QR code access control is the data source feeding everything else: each check-in is time-stamped, which measures real attendance and triggers the alerts.

Julien, founder of a 6-gym chain in and around Montpellier, has 9,000 members paying 39 EUR a month on average. He pays 2,200 EUR a month for club software, i.e. 26,400 EUR a year. He invests 78,000 EUR in custom software. In year one, churn drops from 4% to 3%, i.e. 90 departures avoided per month. Those retained members bring on average 6 more months at 39 EUR, i.e. 90 x 12 x 6 x 39 = 252,720 EUR of preserved revenue over their lifetime. Even counting only 40% of that effect, plus the 26,400 EUR of licences removed, the gain exceeds 127,000 EUR in year one.
FAQ
How much does gym chain management software cost in 2026?
Off-the-shelf software costs 150 to 400 EUR per gym per month, i.e. 10,800 to 28,800 EUR a year for 6 gyms. Custom software ranges from 45,000 to 100,000 EUR depending on the member app and hardware integrations.
Does the software work with our existing turnstiles?
In most cases yes, through a QR reader unit or an integration with the existing controller. A hardware audit takes 1 to 2 days per gym.
How are recurring payments and failed payments handled?
The software manages SEPA mandates in Europe or ACH and card billing in the US, sends payment files and automatically follows up on rejections. In practice, 70% of arrears are recovered within 15 days.
Can churn really drop from 4% to 2.5%?
It is a realistic goal over 12 to 18 months with inactivity alerts, membership freezes and coach follow-up. The software provides the signals, results also depend on how gym teams act on them.
Is member data handled compliantly?
Yes, with consents, defined hosting and retention periods, for example 3 years after membership ends for commercial data, under GDPR in Europe and applicable state rules in Florida.
