Prepare, or have the entity prepare, confirmation requests for the balances or invoices selected. On the confirmation, consider including outstanding balance, terms of sale, a confirmation that delivery has occurred or services have been rendered, and a confirmation that there are no side-agreements that would alter the substance of the sales agreement. Mail the confirmation requests under our control, determine that the requests are properly addressed (i.e., obtain audit evidence about the accuracy and completeness of addresses provided by the entity), and request that all replies be sent directly to our office
