I’m rolling out a complete, end-to-end platform that lets my car-wash business run from any screen. The project covers three fronts at once: a web-based admin dashboard, a native customer app for iOS and Android, and a separate staff-facing app on the same mobile platforms. Customer experience • Book, reschedule, or cancel a wash in a few taps and receive push / SMS confirmation. • Store multiple vehicles, view past services, and collect loyalty points or coupon discounts automatically at checkout. Staff workflow • See assigned jobs, start-to-finish timers, and route guidance. • Clock in/out from the phone so attendance and performance feed straight into the dashboard. Back-office power (web) • Drag-and-drop task assignment, live bay status, and productivity metrics. • Automatic invoicing with tax, discount, and multi-currency support that syncs to accounting exports. • Inventory tracking for soaps, waxes, and other consumables with threshold alerts and one-click re-order. • Real-time charts for daily sales, repeat-customer rates, and employee performance. Core deliverables 1. Production-ready iOS & Android builds for customers. 2. Production-ready iOS & Android builds for staff. 3. Responsive admin dashboard (web) with the modules above. 4. Source code, API documentation, and a brief hand-over session so my team can manage releases in-house. Acceptance criteria • All booking, invoicing, and loyalty logic must persist whether the action happens on mobile or web. • Push notifications land within 2 seconds on average during stress testing. • Inventory and sales reports match sample data sets with 100 % accuracy. • Apps pass App Store / Play Store review without requested changes. If this multi-platform build aligns with your expertise in Flutter, React Native, Kotlin/Swift, or a similar stack, I’m ready to move quickly and block development time immediately after we agree on milestones.
