The Custom Shoe Store (CSS) provides custom fit shoes for its clients who have special orthopedic needs. Customers can login and specify their foot's width and size and see a selection of shoes available. Customers can place online orders or place an order for curbside pickup. For curbside pickup they complete the order online but also have to add a pickup time and location. All orders include giving loyalty points to the customer's account. Employees of CSS can login to the admin side of the system to check their schedule and place their own orders using their employee discount. The employees must also record their absences in the system.
