Gym Management Software: Biometric Attendance, Recurring Billing & Member Retention

The average gym in Kenya loses 40% of its members annually due to poor billing systems, manual attendance, and lack of engagement. Our JNGlobal Gym Management Suite – built for a Nairobi gym that reduced dropout by 45% and increased revenue by 60% – solves every pain point.

Complete Feature Set (From Our Contract with a Westlands Gym)

🏋️ Member Management & Profiles

Store member details, medical conditions, fitness goals, and membership type (monthly, quarterly, annual). Track check‑in history, membership expiry, and freeze periods (e.g., when a member travels).

The system also allows you to upload the member’s photo, which appears on the attendance screen – preventing identity fraud.

🔐 Biometric / QR / RFID Attendance

We integrate with ZKTeco fingerprint scanners (K40 model) or QR scanners. Members touch the scanner – no manual sign‑in. This eliminated “buddy entry” (non‑members sneaking in) completely, saving the gym an estimated KES 50,000/month in lost revenue.

For high‑end gyms, we also support RFID wristbands for contactless entry.

💳 Automated M‑PESA Recurring Billing

Members set up auto‑debit from M‑PESA or card. The system sends a payment reminder 3 days before expiry, processes the deduction on the due date, and updates expiry. If payment fails, the member is suspended after 3 grace days. Late payments dropped from 30% to 0%.

We support flexible payment frequencies: weekly, monthly, quarterly, annually. Members can also purchase additional sessions (e.g., PT) via one‑time payments.

📆 Class Scheduling & Trainer Commission

Schedule yoga, spin, aerobics, or HIIT classes. Members book slots via the mobile app. The system tracks attendance per class and automatically calculates trainer commission (e.g., 10% of class revenue or fixed rate).

Trainers have their own login to see their scheduled classes and attendance.

📊 Full Double‑Entry Accounting for Gyms

We built a mini‑ERP that tracks:

• Membership fees revenue (by plan type)
• Personal training sessions (PTs) – separate billing
• Shop sales (protein, supplements, gear) – integrated inventory
• Expenses: rent, salaries, equipment maintenance, utilities

Generate profit & loss, balance sheet, and cash flow statements – no need for QuickBooks. All reports are exportable to Excel and PDF.

📱 White‑labelled Member Mobile App (iOS & Android)

We developed a Flutter app that includes:

• Check‑in via QR code (generated in the app)
• Class schedule and booking
• Membership renewal (M‑PESA STK push)
• Push notifications (class reminders, offers)

The app was delivered for KES 130,000 (one‑time) as part of the gym’s package. It has a 4.8 rating on Google Play.

📈 Analytics & Retention Tools

Dashboard shows: MRR (monthly recurring revenue), churn rate, most popular classes, peak hours, and staff performance. The gym used these insights to open a new class at 6am, which now generates 20% of total revenue.

We also provide a “churn prediction” report that flags members who haven’t visited in 14 days, allowing the gym to send personalised offers.
