Focused on improving the operational efficiency of chain repair shops and optimizing customer service experience, we introduce advanced system integration solutions tailored to repair shop scenarios, building an integrated information system matrix covering store parts management, customer service tracking, and headquarters operation control. The system can seamlessly connect with the repair shop's existing Maintenance Management System (MMS). Through functions such as automatic synchronization of parts demand, real-time inventory alerts, and full visibility of order status, it simplifies the store's parts procurement process. With the customer service module, it establishes full-cycle management including maintenance records, maintenance reminders, and after-sales follow-ups to improve customer repurchase rate. The headquarters can real-time monitor core indicators of each store such as parts consumption, inventory turnover, and customer satisfaction through the system data dashboard, and provide parts stocking suggestions and operational optimization plans for stores based on big data analysis. Meanwhile, it integrates parts traceability function, allowing users to query parts authenticity and quality assurance information by scanning QR codes, comprehensively improving store operational efficiency and customer trust.
