Gym Automation: Biometric Attendance & Recurring M‑PESA Billing – How We Helped a Gym Increase Retention by 45%

Automation is the key to turning a struggling gym into a profitable one. This post details our Gym Management Suite implementation for a Westlands gym, including biometric attendance and auto‑billing.

The gym had 800 members, but 40% left every year due to late payments and lack of engagement. Manual attendance allowed “buddy entry” – non‑members using a friend’s pass. Staff spent 3 hours daily on billing and attendance logs.

We installed biometric fingerprint scanners (ZKTeco K40) and integrated them with our system. Members now check in by fingerprint – no more buddy entry. We enabled auto‑renewal via M‑PESA; members authorise once, and the system deducts fees on expiry. If a payment fails, the member receives an SMS reminder and has 3 days to pay before suspension.

Results after 6 months:

• Member dropout reduced from 40% to 22% (45% improvement).
• Revenue increased by 60% (more renewals and new sign‑ups via the member referral app).
• Staff hours saved: 20 hours per week.
• Late payments: eliminated.

We also provided a white‑labelled mobile app (iOS & Android) for members to check in, book classes, and top up.
