I need a full-stack ERP that serves my passenger-transport business on both web and mobile. The core of the platform must behave as a business-management system rather than a simple booking or payment tool. Within that ERP I want three working pillars ready for day-to-day use: • Project management – to schedule routes, vehicles, and driver assignments just like tasks and sprints. • Customer relationship management (CRM) – a space to log leads, ride history, feedback, and loyalty perks. • Reporting & analytics – dashboards that visualise occupancy, revenue per kilometre, on-time rates, and any KPI I decide to feed in. I am open to the tech stack as long as it is modern, scalable, and gives me a single codebase for web plus iOS and Android (React, Flutter, or similar frameworks are fine). Please factor in role-based access, multi-location support, and a clean REST/GraphQL API so I can hook it into existing payment and GPS systems later. When you respond, share a quick outline of the architecture you’d propose and highlight one past project where you delivered comparable ERP functionality across web and mobile.
