Dell has grown significantly through e-commerce by implementing a disintermediated and real-time production supply chain model. Dell cuts out retailers by selling directly to customers online. Dell also only manufactures PCs after receiving customer orders using just-in-time production, allowing Dell to ship PCs within 24 hours while reducing inventory costs. Dell's e-commerce website allows for product customization, online ordering and payment, order tracking, and customer support, fueling over $1 million in online sales by 1997.
