The Manage Orders use case is a critical component of any e-commerce platform. It involves a series of actions that enable customers to purchase items, request prices, and staff to order stocks from suppliers. Customers must be able to browse through the available products, select the items they want to purchase, and complete the checkout process. Additionally, customers should be able to request prices for specific products, which can be useful when they want to buy in bulk or negotiate a better deal. On the other hand, staff members must be able to order stocks from suppliers to ensure that the inventory is always up-to-date. This use case is essential for any business that wants to provide a seamless shopping experience to its customers while maintaining a healthy stock level.
