Indoor shooting range lane booking platform

We manage an indoor shooting range with 14 lanes and need a single web application that handles the entire operational workflow. The core is a lane booking calendar where shooters reserve specific lanes in fixed time slots (30, 60, or 90 minutes). The grid shows real occupancy per bay, prevents double-booking through row-level locking, and lets staff drag reservations between lanes. Before the first visit, every client must fill out a safety agreement and waiver form; both documents are signed electronically — capturing signature image, timestamp, and signer's IP, then saved as an immutable PDF for legal storage. Admission rules check minimum age, identity verification, and any instructor notes. Membership is tiered (day pass, monthly, annual, Pro) with different rates, discounts, guest limits, and priority booking windows; upgrades and renewals go through a personal account. Equipment and lane rental have their own inventory with availability per item, deposit holds, and return checklists. Training courses (basic pistol, concealed carry, defensive rifle) are scheduled with seat limits, instructor assignment, and waiting lists. The shop sells ammunition and supplies with inventory control, tax compliance, and point-of-sale pickup. A league module records match results, ranks members over a season, and publishes tournament standings. Result: responsive frontend, staff panel, Stripe payments, role-based access for instructors and cashiers, e-mail and SMS reminders, complete API documentation. Source code, deployment, and two-week warranty included.
