Product · Two worlds
One backend. Two surfaces. Staff is co-branded Offsides × Club. The member app wears the club's kit — Offsides only as a powered-by line in the club's text colour.
Web. The full board. Owners, managers, front desk.
One Flutter binary. Theme and labels load at runtime.
The engine
Tier windows, peak pricing, cancellation policy. Price frozen when the row is written. Race-proof conflicts.
Classes, events, clinic credits, guest passes. Feature flags hide what a club does not run.
QR or manual. Tolerance window. Front desk can still walk someone in.
Stripe Connect Express. Club is merchant of record. Application fee only — see pricing.
Whitelabel
Onboarding is a clubs row (labels + flags), resources and tiers, optional floor layout, and a connected Stripe account. No rename. No migration. No redeploy.
User-facing words come from the club. The schema says resource, session, tier.
Proof
A court club with a floor plan. A gym with mats, classes, and the map switched off. Same app. Different labels.
