Supreme Ventures is a manufacturer of quality home accessories and a client of your audit firm. You are carrying out the audit of the purchases system of Supreme Ventures. The company has revenue of Ghc 12.5 million, and all the shares are owned by Mr. Addo and Mr. Tekpe, who are non-executive directors and are not involved in the day-to-day running of the company. Kofi Badu is the accounts clerk who maintains all the accounting records and prepares the annual financial statements.The company uses a standard computerised accounting package. You have determined that the purchases system operates as follows: When materials are required for production, the production manager sends a handwritten note to the buying manager. For orders of other items, the department manager or managing director sends a handwritten note to the buying manager. The buying manager finds a suitable supplier and raises a purchase order. The purchase orders are signed by the managing director. Purchase orders are not issued for all goods and services received by the company. Materials for production are received by the Goods Received Department, who issue a goods received note (GRN), and sends a copy to the accounts clerk. There is no system for recording receipt of other goods and services. The accounts clerk receives the purchase invoice and matches it with goods received notes and purchase order (if available). The managing director authorises the invoice for posting to the purchase ledger. The accounts clerk analyses the invoice into relevant nominal ledger accounts codes and then posts it. At the end of each month, the accounts clerk prepares a list of payables to be paid. This is approved by the managing director. The accounts clerk prepares the cheques and remittances and posts the cheques to the purchase ledger and cashbook. The managing director signs the cheques and accounts clerk sends the cheques and remittances to the payables.
