You are the auditor of VI-YO (Pty) Ltd, which is a manufacturer of printing equipment. The company sells its products to wholesalers and a few retailers. Mr William Fence, the managing director of the company, is concerned about the sales and receipt system currently in place and has asked for assistance in this regard. The following systems description was obtained from the sales and receipt system. Mrs Khwezi, the receptionist, is responsible for opening all incoming e-mail. All orders that are received by mail are sent directly to the sales department, while all cheques and monies received are sent to Mrs Collect, the debtors clerk. Mrs Collect enters the payments into the debtors' accounts and deposits the cash and cheques into the company bank account. After receiving an order via mail or telephonically, the sales department creates three copies of the sales order. The sales manager reviews and approves the sales orders before they are dispatched. The first copy of the sales order is sent to the credit controller, who authorises the order after the client's creditworthiness and credit limit have been approved. The second and third copies are delivered to the finished goods warehouse for the inventory to be withdrawn. The dispatch department physically inspects the goods that are received from the finished goods store and compares it to the third copy of the sales order. Thereafter, two copies of the sales invoice are prepared in duplicate. The first copy is included in the shipment together with the goods to the customer, and the second copy is sent to Mrs. Collect, the debtors clerk. Mrs. Collect verifies all the calculations on the sales invoice and compares the prices to the latest price list. She then updates the debtor's account with the sales invoice. Mrs Collect generates and mails monthly statements to debtors at the end of each month after reconciling the debtors ledger to the debtors control account.
