An audit tool (AT) operates in cooperation with an audit tool manager (ATM), a policy file (PF) and a query file (QF) in order to provide a real time display of usage within an on-demand service system. The ATM identifies the data to be gathered. Using the ATM, the user identifies comparison points, maps the comparison points to audit controls, defines policies and develops SQL queries to report transactions and record quantities. The AT gathers data, displays the gathered data, and compares the data points, and alerts the user to a discrepancy. The AT displays the compared data points side by side so that real time visual verification can be made, and the AT also alerts the user to discrepancies.
