The verdict in three sentences
For a chain of 7 clubs and 9,000 members, a mainstream platform such as Mindbody costs roughly USD 25,000 to 59,000 a year once add-ons are counted, and the member experience stays tied to the vendor. Custom software covering memberships, recurring billing, QR code access control and class booking runs, as a 2026 order of magnitude, USD 40,000 to 75,000 for 12 to 16 weeks of work. The real win is monthly churn: dropping from 4.5 % to under 3.5 % is worth more than the licence savings.
Platform subscription or your own branded software
Platforms like Mindbody, ABC Glofox or Zen Planner do the basics well: member records, contracts, payments, and Mindbody adds marketplace visibility. Their limits show as a chain grows: generic or add-on branded apps, partial usage data, payment processing margins, and dependence on the vendor roadmap for every new plan. Compare over 4 years.
| Criterion | Mindbody or similar | Custom software |
|---|---|---|
| Annual cost for 7 clubs | USD 25,000 to 59,000 (USD 300 to 700 per location per month) | maintenance and hosting, set in the quote |
| 4 year cost (order of magnitude) | USD 100,000 to 235,000 | USD 40,000 to 75,000 build + maintenance |
| Mobile app | vendor app or paid branded add-on | fully branded to the chain |
| Plans and promotions | limited to built-in options | any rule (referrals, off-peak, couples) |
| Usage data | partial export | full warehouse, disengagement alerts |
| Payment processing | vendor rates, often above 2.9 % + USD 0.30 | your own processor and ACH rates |
| Time to launch | 4 to 8 weeks | 12 to 16 weeks |
Platform prices above are 2026 estimates for mid-sized US chains and vary with tier and add-ons.
The modules that reduce churn
A member who has not checked in for 14 days is much more likely to cancel within two months. The software therefore records every QR scan and triggers action. Class booking with waitlists fills evening slots. Automated nudges offer a free class or a session with a coach. Failed payments are retried automatically with a personalised message instead of a collections letter three weeks later. ACH payments reduce card decline rates for long-term members.
| Module | Expected effect (estimate) | Share of budget |
|---|---|---|
| Memberships, card and ACH billing | failed payments handled in 48 h instead of 3 weeks | 25 % |
| QR code access control | entry under 2 seconds, turnstile integration | 15 % |
| Class booking and waitlist | class fill rate from 60 to 80 % | 20 % |
| Branded mobile app | 50 to 70 % of active members on the app | 25 % |
| Disengagement alerts and CRM | 0.5 to 1 point less churn | 10 % |
| Chain dashboards | revenue per club, check-ins per hour | 5 % |

Points to watch in Miami
Seasonality is real: snowbirds from November to April and short-stay visitors in summer. The software must handle 1 to 3 month passes without distorting churn statistics. Florida's health studio rules require written contracts and clear cancellation rights, and card data must stay with a PCI DSS compliant processor so the chain never stores card numbers.

Marcus, founder of a 7 club chain between Brickell and Fort Lauderdale, has 9,000 members paying an average USD 49 a month, or USD 441,000 in monthly revenue. He pays about USD 550 per location per month for his platform and add-ons, USD 46,200 a year. His monthly churn is 4.5 %, or 405 cancellations a month. Bringing it to 3.5 % avoids 90 cancellations a month. With a cautious 6 extra months of lifetime, each saved member is worth USD 294: 90 x 294 = USD 26,460 of revenue preserved per month, about USD 317,000 a year. Combined with the licence savings, a USD 60,000 build pays back within a few months.
FAQ
Can we keep our current turnstiles?
In most cases yes, through a controller interface or a small gateway device. Allow 1 to 2 weeks of integration per hardware model.
How do we migrate 9,000 recurring payments?
Card tokens can usually be transferred between PCI compliant processors on request, so members do not re-enter cards. Plan 2 to 3 weeks with both processors.
Is the app published under our name?
Yes, on the App Store and Google Play under the chain's developer account. Store review usually takes 1 to 2 weeks.
How long is the rollout?
Between 12 and 16 weeks, with one pilot club for 2 weeks before the other 6.
What about member privacy?
Check-in data is kept for a stated purpose and limited period, for example 24 months, with a clear privacy notice. Card data never touches your servers.
