AutoHub – Smart Car Wash & Garage Management Platform

AutoHub is an enterprise-grade, multi-tenant Car Washing, Auto Detailing, and Garage Management ERP platform built with Flutter and Google Firebase. It empowers vehicle wash centers, detailing studios, and automotive workshops to streamline daily counter operations, automate vehicle check-ins, record multi-mode payments, eliminate outstanding customer debts with automated WhatsApp payment reminders, track operational expenses, and generate professional PDF ledger and business audit reports.

🌟 Key Features
