You are a senior auditor with Rodriguez & Jones, a small auditing firm located in Canterbury, an eastern suburb of Melbourne, Victoria. Your team has been assigned to the audit of a new client, Millers Merchandise, for the year ended 30th June 2021. Millers Merchandise is a Deepdene-based wholesaler offering for sale everything from baby food and beverages, to snacks and vegetables, and everything in between.

You are planning the audit of accounts payable, where preparatory work has revealed the following:Millers Merchandise purchases its stock from a list of approved suppliers, with purchase orders processed electronically through a business-to-business ecommerce system. This system uses a fast chain model of supply, with suppliers electronically transmitting their invoices this automated approach means supplier invoices are credited directly to the accounts payable file of Millers Merchandise upon receipt of the purchase order. You are concerned about the impact this might have on the existence assertion.

A key control to safeguard the Valuation and Allocation assertion, is the use of key entry validation an IT control whereby the Number of Units Purchased is multiplied by the Unit Cost, and compared with the Total Cost as per the suppliers invoice.As is always the case with accounts payable and purchases, you are have flagged the need to investigate the risk associated with the completeness assertion. As Millers Merchandise operates both in a B2B and B2C environments, you need to test the security and operation of these systems. You are concerned there may be some overlap, thereby putting the classification assertion at risk.The owner of Millers Merchandise (Suzie Miller) owns and operates another business, Brazeele Mottley, out of Broadmeadows. To make most use of the combined purchasing power, Suzie combines purchases for both businesses where possible. This makes you concerned the rights and obligation assertion for Millers Merchandises accounts payable may be at risk.
