Superior Shoe Wholesaler (SSW) sells a wide variety of footwear from boots to athletic shoes to sandals. They acquire shoes from manufacturers and designers in very large lots and resell them nationwide to retailers. SSW enters vendors into their system as soon as they are identified and they record the price quote for the shoes they purchase from each vendor. They can receive price quotes for the same shoe from multiple vendors. SSW buyers place orders with the vendors and can negotiate discounts from the quote price of the shoe purchased. Payment is made to vendors at the end of each month for all outstanding purchases.

SSWs customers are the end retailers such as Macys, DSW, and Nordstrom. SSW assigns a specific sales rep to each customer who can offer discounts to the customers for bulk sales. The price of shoes will fluctuate based on season and fashion trends. Customers are required to pay in full before delivery. SSW delivers shoes to their customers with their own trucks. Each truck is loaded with one customers order and the trucker delivers the shoes to the customer. SSW tracks deliveries and truckers. Trucks are owned by SSW and truckers are employees of SSW.

Cashiers process cash receipts and cash disbursements. Cash disbursements and cash receipts can occur in other cycles not described in this narrative. Cashiers, sales reps, and buyers are modeled in one employee group.
