PART A: ORIENTAL TRADERS INTERVIEW WITH THE PURCHASING MANAGER A purchase requisition is raised within the various departments and sent from the inventory management system to the purchasing department clerk. The clerk prepares the purchase order (PO) using the supplier and inventory files. Once the PO is approved by the purchasing manager, it is automatically emailed to the supplier. The supplier returns a supplier confirmation to the clerk indicating receipt of the PO. The purchasing clerk then sends a PO notice to the Accounts Payable (AP) clerk. When the receiving department accepts the goods from the supplier, the inventory management system automatically send the AP clerk a receiving report. The AP clerk also receives the tax invoices directly from the suppliers. The supplier tax invoices are matched to the PO notice and the receiving report by the AP clerk. If all documents match, payment is authorised and the AP clerk updates the accounts payable master file. Payment request is then sent by the AP clerk to the accounting department. All files at Oriental Trading are filed in date order. The accounting department then prepares the EFT file for vendor payment. Once the payment has been approved, the system automatically updates the AP master file and the general ledger, and forwards the payment details to the bank.
