10 10 of 22 Accounts Payable Testing Case Study Background: XYZ Corporation is a manufacturing client with offices at multiple locations. We have been engaged to provide services to the internal audit function of XYZ Corp. The client recently acquired a new business unit and is facing issues integrating the financial systems from the newly acquired business. The client is particularly concerned that these issues could be more significant around accounts payable processing and supplier master maintenance and could result in missing or invalid information or duplicate disbursements that might have been made due to lack of controls. The client is also unsure whether the user rights are properly set up to access/update various files. The internal audit function does not currently have the skill set to develop the data analytics that might help them better gauge the extent of the problem and the client has reached out to us for help. They would like us to test vendor master data and transactional information for the period starting 01/01/2009 to 12/31/2009.
