Security-For-All Bhd (MFA) is a company specializing in installing and maintaining security systems for businesses and residential customers. It has been operating for 10 years. The company buys supplies ranging from CCTV cameras, smart locks, keypad locks, sensors, alarms, smoke detectors and other equipment from reputable vendors in town for customers' installations.

-The purchasing process starts with filling up of purchase requisition forms by the Inventory Department when the inventory level reaches the re-order point. They then select appropriate vendors by searching them online. Next, they phone the vendors, request one price quotation for each item and give the vendors a verbal order.

-The filled up purchase requisition forms are sent to Purchase Department. A pre-numbered purchase order is processed by the department for each requisition and filed together with the earlier purchase requisition form.

-When the items have arrived, the Receiving Department takes charge and informs the Inventory Department orally. The receiving clerk then stamps the purchase order with the date received and noted any difference between the quantity shown on purchase order and the quantity received. The receiving clerk then forwards the stamped purchase order and items received back to the Inventory Department for verification and correction. At the same time, the receiving clerk informs the Accounts Department that the order has arrived.

-The Accounts Department then waits for the vendors' invoice to arrive. The account clerk files together the vendors' invoice and purchase order copy received earlier from the Inventory Department. On a monthly basis, the account clerk prepares cheque to be paid to each vendor and sent the cheques to the Treasurer for signature. The treasurer then signs the cheques.

Although the company has expanded over the years with more than 100 active vendor accounts currently in the accounts payable's ledger, it continues to rely on a manual system to process all purchase transactions. In addition, the company has no specific policy on purchase returns. For many years, the defect inventories are simply kept in store without any follow ups and actions by the storekeeper in the Inventory Department.

The company maintains its existing auditor for the current financial year ended 31 December 2020. The auditor is concern that the recent pandemic has resulted in surge of inventory prices supplied by vendors due to inadequate supply and rising demand from customers for tightened security measures.
