The Manage Orders use case is an essential feature of any e-commerce platform. It allows customers to purchase items from the online store, request prices for specific products, and enables staff to order stocks from suppliers. Customers must be able to browse through the available products, add them to their cart, and complete the checkout process. Additionally, customers should be able to request prices for products that are not listed on the website or for bulk orders. On the other hand, staff members should be able to manage the inventory levels and order stocks from suppliers when the stock levels are low. Overall, the Manage Orders use case is crucial for ensuring a smooth and efficient ordering process for both customers and staff.
