Question: CZ Corporation is a major vendor of office supplies, furniture and equipment. CZ's sales representatives call on customers to take orders. The sales representatives write up the orders and turn them in to a sales order processing (SOP) clerk at the regional center. If the ordered items are in stock, the SOP clerk prepares a picking slip (stock copy) and a packing list for each order. If any of the ordered items are out of stock, the SOP clerk completes an Out Of Stock Notice form, which notes the name of the customer requiring the items and forwards it to Purchasing. A Purchasing clerk then completes a purchase order, which is mailed to a supplier. The SOP clerk notes back-ordered items on the customer's order and forwards a copy of the annotated customer order to Accounts Receivable (A/R) where an A/R clerk prepares an invoice and sends it to the customer. The SOP clerk also forwards a picking slip and packing list to the Warehouse, where stock pickers fill the order, placing ordered items into boxes along with the packing list. The boxed items and packing list are held for delivery, usually via UPS.
