The verdict in three sentences
Above 5,000 members, the per-member fee of gym management software often exceeds the cost of a proprietary tool amortised over 4 years. Custom software at USD 50,000 to 90,000 brings memberships, recurring billing, access control and class booking into a single database. The real financial lever is reducing failed payments, from 3 to 6% of revenue to under 2%.
The real cost of software billed per member
Off-the-shelf gym software usually charges between USD 1 and 2.50 per active member per month, with paid add-ons for the member app or access hardware. For a 6-location chain in Miami, the bill grows with every new member.
| Item (2026 order of magnitude) | Off-the-shelf software | Custom software |
|---|---|---|
| Upfront cost | USD 2,000 to 7,000 setup | USD 50,000 to 90,000 |
| Recurring cost for 7,500 members | USD 7,500 to 18,750/month | USD 1,000 to 1,800/month (hosting and maintenance) |
| White-label member app | USD 350 to 900/month add-on | included |
| 4-year cost | USD 365,000 to 905,000 | USD 98,000 to 176,000 |
| Adding a 7th location | automatic fee increase | near-zero marginal cost |
| Ownership of member data | limited export | full, PostgreSQL database |
Even at the low end of market pricing, a chain this size spends over USD 90,000 a year. Custom software pays back in under 12 months in this scenario.
Must-have features and their budget
The scope should cover the whole member journey, from online sign-up to cancellation that complies with the FTC click-to-cancel principles and Florida contract rules.
| Module | Scope | Indicative budget |
|---|---|---|
| Memberships and contracts | plans, commitments, freeze, referrals, online cancellation | USD 10,000 to 16,000 |
| Recurring billing | card and ACH, dunning, automatic retries | USD 9,000 to 14,000 |
| Access control | QR code, key fob, turnstiles, hours per plan | USD 8,000 to 17,000 |
| Class booking | schedule, capacity, waitlist, cancellation | USD 7,000 to 11,000 |
| iOS and Android member app | booking, payment, workout tracking | USD 11,000 to 20,000 |
| Chain dashboards | churn, revenue per location, attendance | USD 5,000 to 12,000 |
Regulators increasingly require cancelling to be as easy as signing up: the contract module should include an online cancellation flow from V1.
Reducing failed payments: the most profitable lever
With 7,500 members paying USD 40 a month on average, monthly revenue reaches USD 300,000. Each point of failed payments is worth USD 36,000 a year.
| Anti-failure measure | Observed effect (estimate) |
|---|---|
| Automatic retry at D+3 and D+7 | 40 to 55% of declines recovered |
| SMS and push before due date | 10 to 15% fewer declines |
| Card update from the app | 20% fewer manual follow-ups |
| Access blocked after 2 declines | settled within 7 days in 60% of cases |
| Card account updater service | 5 to 10% additional recovery |

FAQ
How much does custom software for a gym chain cost?
Budget USD 50,000 to 90,000 for memberships, billing, access, booking and a member app. Maintenance and hosting run USD 1,000 to 1,800 a month.
Can we keep our current turnstiles and badge readers?
In most cases yes, through the existing access controller or a gateway. Allow USD 1,700 to 4,500 per location if an interface box is needed.
How do we migrate 7,500 members and their payment methods?
Card data is migrated securely between PCI-compliant processors as tokens, never in clear. Migration takes 2 to 3 weeks, with a parallel run over one billing cycle.
How long until go-live?
A first lot covering memberships and billing can ship in 10 to 12 weeks. The full project with the member app takes 4 to 6 months.
Is member data protected?
Yes: US hosting, configurable retention periods, logged consents and no card data stored on our side. Access logs are purged automatically, for example after 12 months.
