The verdict in three sentences
For an 18-club fitness franchise in Nice, the choice is not between buying everything and building everything: the best option is almost always a market vendor for club operations, extended with a custom overlay at EUR 25,000 to 60,000 excl. VAT for what the vendor does not do. The overlay handles automatic royalty calculation, network-wide corporate memberships and churn tracked per club. Over three years it costs less than a premium vendor and gives the franchisor data it controls.
What the vendor does well, and what it does not
Club management software costs EUR 150 to 400 per club per month in 2026. It handles a gym's daily operations well. It is much less comfortable with the franchisor and franchisee relationship.
| Function | Market vendor | Custom overlay |
|---|---|---|
| Memberships, SEPA direct debits | Yes, core product | Read via API |
| Access control (badge, QR, app) | Yes, with compatible turnstiles | Consolidated visits per club |
| Class schedule and booking | Yes | Not needed |
| Royalty calculation (5 to 8% of revenue) | Manual export, Excel rework | Automatic, monthly invoice to franchisee |
| Multi-club corporate memberships | Rarely, priced per club | Single contract, access to the whole network |
| Churn and cohorts per club | Local statistics | Network ranking, alerts at D+14 without a visit |
| Franchisor dashboard | Limited or paid add-on | Designed for the network |
Integration relies on the vendor's API: check it before signing anything, as some vendors charge EUR 50 to 150 per month for API access, or refuse it.
3-year TCO for 18 clubs
| Scenario | Licence cost | Development | Maintenance and hosting | 3-year cost (estimate) |
|---|---|---|---|---|
| Premium vendor only (EUR 350 per club) | EUR 226,800 | EUR 0 | Included | EUR 226,800 + EUR 75,000 of manual rework |
| Standard vendor (EUR 200 per club) + overlay | EUR 129,600 | EUR 25,000 to 60,000 | EUR 400 to 800 per month, i.e. EUR 14,400 to 28,800 | EUR 169,000 to 218,400 |
| Full custom build | EUR 0 | EUR 150,000 to 250,000 | EUR 2,000 to 4,000 per month | EUR 222,000 to 394,000 |
| Different vendor per franchisee | EUR 97,200 to 259,200 | EUR 0 | Included | Data cannot be consolidated |
The manual rework in the vendor-only scenario is roughly a half-time financial controller (EUR 25,000 a year fully loaded) reconciling revenue, discounts and royalties. A full custom build only makes sense beyond 50 to 80 clubs, or if the brand wants to sell its technology.
The metrics that change how the network is run
A franchisor steers by three numbers per club: active members, monthly churn rate (often 3 to 5% in budget fitness) and declared revenue, which is the royalty base. The overlay computes them every night, ranks clubs against each other and triggers an alert when a member has not visited for 14 days, a strong signal of upcoming cancellation. Corporate memberships, sold at EUR 25 to 45 per employee per month to employers in Sophia Antipolis or at Nice Côte d'Azur airport, also need a single contract and automatic revenue sharing between clubs based on visits.
Mini case study
Thomas, founder of an 18-club brand in Nice and along the Riviera, has 27,000 members at EUR 35 per month and collects a 6% royalty. His controller spends 3 days a month calculating royalties, about EUR 9,000 a year. The chosen overlay costs EUR 40,000 excl. VAT and EUR 600 per month. Thanks to inactivity alerts, churn drops from 4% to 3.5% per month: about 135 members retained each month, worth close to EUR 340,000 of network revenue a year, of which EUR 20,400 in royalties. Annual gain for the franchisor: 20,400 + 9,000 - 7,200 = EUR 22,200, so payback in about 22 months, plus more profitable franchisees.

FAQ
How much does gym management software cost in 2026?
Vendors charge EUR 150 to 400 per club per month, depending on access control, member app and member count. A custom network overlay costs EUR 25,000 to 60,000 excl. VAT.
Can the same software be imposed on all franchisees?
Yes, if the franchise agreement provides for it and the cost is transparent. It is the condition for consolidating memberships and royalties across the 18 clubs.
How are royalties calculated automatically?
Each month the overlay pulls revenue collected per club through the API, applies the contractual rate (for example 6%) and generates the invoice. The franchisee approves in one click instead of sending a statement.
What churn rate should a fitness network target?
As a 2026 estimate, 3 to 5% per month in budget gyms and 1.5 to 3% in premium. Gaining 0.5 points on 27,000 members is worth several hundred thousand euros of network revenue.
How long does it take to deploy the overlay?
Allow 10 to 16 weeks, including 3 to 4 weeks of testing on two pilot clubs before opening it to the whole network.
