You are the auditor of Darwin Storage Pty Ltd (DSPL), which manufactures steel storage drums. One of the directors of DSPL has requested that you perform a review of the internal controls within the purchase and payments cycle of the company's operations. From your discussions with management and staff, you ascertain that the company is a small operation, operates from one location in Darwin, and only has the following staff: . Five directors (one of whom, the CEO, is responsible for the day-to-day operations of the company) . A warehouse manager . An assistant to the warehouse manager . A secretary/receptionist . An accounts receivable clerk . A banking clerk . An accounts payable clerk . Three machinery operators are involved in the manufacturing process. The warehouse manager is able to order from any supplier and will usually telephone a number of suppliers to obtain quotes. The warehouse manager will then order from one of these suppliers by telephone and confirm the order by facsimile. The only documentation kept is the facsimile confirmation of order, which is kept by the warehouse manager.Once an order has been confirmed, the warehouse manager will complete a purchase order (PO). The warehouse manager keeps one copy of the PO and the other is forwarded to the accounts payable clerk, who files it in date order. When goods are received at the warehouse, the warehouse manager checks the goods received to the delivery note attached to the goods and signs the delivery note as evidenced of this check. The delivery note comprises two copies, one of which is retained by the person delivering the goods and the other by the warehouse manager. The warehouse manager forwards a copy of the signed delivery note to the accounts payable clerk, who posts a journal entry to the creditors ledger for the amount shown on the delivery note. The clerk then stamps the delivery note 'entered' and files the delivery notes by supplier.
