Let's understand first, how does e-commerce work? A customer browses through the catalog of an e-commerce website or e-commerce mobile app. Then the customer selects products to purchase and adds them to the shopping cart. The customer checks the order details and then checkout to pay online. E-commerce seller receives the order and confirms it to the buyer. The seller packs the product from inventory and processes it through a shipping company like FedEx. Shipping company collects the product parcel and ship to the customer's address. In between, an online FedEx tracking service is available to the customer through the link provided. The customer receives the product ordered and write a review for the product and seller's service.
