Car-Wash & Auto-Detailing Booking App with Wash Memberships

I run a car-wash and auto-detailing business with several wash bays, and I want a proper booking app that customers use from their phone instead of queuing at the door. The core of it is the package catalog and the scheduling: drivers pick a wash or detailing package, choose the vehicle they are bringing in, and grab an open slot on one of the bays. Each bay has its own working hours and handles a different number of cars per hour, so the calendar must know how long each package takes and never double-book a bay. When someone reserves a slot I want the app to hold that time, send a confirmation, and let the customer reschedule or cancel within the rules I set. This is specifically an auto-services product built around wash bays and packages, not a general appointment tool and not a repair-shop system that tracks parts and mechanic jobs.

The part that matters most to my revenue is memberships. I sell unlimited-wash monthly plans and I need the app to handle them end to end: sign-up, recurring billing, plan tiers, pausing, and a clear rule for how often a member can wash per day. Members should get faster booking and priority slots, and the app must instantly show staff at the bay whether a plate or account is an active member. Alongside that I want vehicle profiles so a customer can save several cars with make, size class and plate, because pricing and slot length depend on vehicle size. Finally a loyalty stamp system: every paid wash earns a stamp, a full card unlocks a free wash or an upgrade, and I can run seasonal bonus-stamp promotions. I need clean admin screens to manage packages, prices, bays and staff, plus simple reports on bookings, membership churn and busy hours.

Please build both the customer-facing side and the staff dashboard, with reliable notifications and a payment flow that supports one-off package payments and recurring membership charges. Design should be mobile-first and quick, since most bookings happen on the go.
