SCM (supply chain management) is a systematic approach to managing the flow of goods and services from suppliers to customers. It includes the coordination and integration of all activities involved in sourcing, procurement, conversion, and logistics management. E-commerce is reliant on SCM to ensure that goods and services are delivered to customers in a timely and efficient manner. SCM is important in e-commerce because it enables businesses to manage their supply chains more effectively and efficiently, ultimately leading to improved customer satisfaction and increased profits.
