Abstract: The rapid digital transformation of the automobile service industry has highlighted the inefficiencies of traditional workshop management methods, especially in multi-brand environments. Manual billing, fragmented inventory tracking, and inconsistent labor pricing frequently lead to revenue losses and customer dissatisfaction. Motor Car Hub is developed as a comprehensive Enterprise Resource Planning (ERP) system built on the MERN stack—MongoDB, Express.js, React.js, and Node.js—to address these challenges. Untitled document (2)This study expands on the original system architecture, presenting a deeper analysis of module interactions, database workflows, performance benchmarks, and the measurable operational improvements achieved in real-world simulations. The enhanced paper discusses MERN-driven scalability, the significance of schema flexibility, automated GST-compliant billing, technician performance tracking, inventory forecasting, and role-based access governance. The system shows an 80% reduction in invoice processing time, complete elimination of manual billing discrepancies, and substantial gains in accountability. These expanded insights provide strong evidence that MERN-based ERP solutions can revolutionize automotive workshop management, making operations more transparent, accurate, and data-driven.
