The company does not have an internal audit department. Sales ordering, goods despatched and invoicing Each customer has a unique customer account number and this is used to enter sales orders when they are received in writing from customers. The orders are entered by an order clerk and the system automatically checks that the goods are available and that the order will not take the customer over their credit limit. For new customers, a sales manager completes a credit application; this is checked through a credit agency and a credit limit entered into the system by the credit controller. The company has a price list, which is updated twice a year Larger customers are entitled to a discount; this is agreed by the sales director and set up within the customer master file Once the order is entered an acceptance is automatically sent to the customer by mail/email confirming the goods ordered and a likely despatch date. The order is then sorted by address of customer. The warehouse closest to the customer receives the order electronically and a despatch list and sequentially numbered goods despatch notes (GDNs) are automatically generated. The warehouse team pack the goods from the despatch list and, before they are sent out, a second member of the team double checks the despatch list to the GDN, which accompanies the goods. Once despatched, a copy of the GDN is sent to the accounts team at head office and a sequentially numbered sales invoice is raised and checked to the GDN. Periodically a computer sequence check is performed for any missing sales invoice numbers.
