The retail and e-commerce industry operates in a highly dynamic environment characterized by high transaction volumes, multi-location inventory, rapid order-fulfilment expectations, frequent returns, and increasing customer demand for speed and service visibility. In such a context, effective supply chain coordination is critical for inventory availability, order accuracy, warehouse efficiency, logistics synchronization, and customer satisfaction. Enterprise Resource Planning (ERP) and SAP-enabled systems are increasingly used to integrate procurement, inventory, warehousing, logistics, order processing, and information flow across departments. The present study examines the role of ERP/SAP-enabled systems in improving supply chain coordination in the retail and e-commerce industry. The study is based on both primary and secondary data. Primary data were collected through a structured questionnaire from 122 respondents associated with procurement, inventory, warehouse, logistics, supply chain, and ERP-related functions in retail and e-commerce organizations. A descriptive research design and percentage-based analysis were used for interpretation. The findings indicate that ERP/SAP-enabled systems have a generally positive impact on supply chain coordination. A substantial proportion of respondents reported that ERP/SAP is either fully or partially implemented in their organizations, with warehouse management and order processing emerging as the most common application areas. The study further reveals that ERP/SAP contributes positively to interdepartmental coordination, operational decision-making, supplier coordination, dispatch support, and customer order tracking. At the same time, implementation challenges such as training and skill gaps, resistance to change, and system integration complexity continue to affect the extent of benefits realized. The study concludes that ERP/SAP-enabled systems function as important strategic and operational tools for improving supply chain coordination in the retail and e-commerce industry, provided that organizations invest in proper training, deeper integration, and disciplined system usage.
