The buyer of our company will track supplier’s production process after the purchasing order is placed, so as to ensure that the supplier can complete ordered goods on time with good quality and full quantity, and then deliver goods to the designated warehouse within the required delivery time. Our quantitative study of what Account & Self-Service features are most important to users shows that the order-related features generally dominate what users use their e-commerce account for; that is, order tracking, returns, order history, receipts and invoices, and editing or cancelling orders. It’s understandable that order tracking is the primary reason why users visit the accounts area of e-commerce sites: users have recently placed an order and want to ensure that everything’s on track for the delivery.
