Full stack / Case study
PumpZone.
One operations hub for the gym floor, cashier, and management.
The system
Built around three daily jobs
Gym operations cross the front desk, point of sale, and manager's desk. PumpZone gives each job its own interface while keeping the underlying records connected.
Reception
Check-in kiosk
Staff can find members, log check-ins, and record walk-in passes with cash or e-wallet payment.
Sales
Cashier POS
The cashier handles retail sales, new memberships, renewals, and an end-of-day tally.
Management
Admin dashboard
Admins can review members and attendance, track plan expirations, adjust prices, and inspect live charts.
Engineering choice
Keep sales and stock in sync
Retail checkout verifies available stock, decrements inventory, and writes the sale inside one database transaction. If a product has insufficient stock, the transaction stops before recording a completed sale.
