The following describes ACL’s Accounts Receivable Aging feature using the Sales Invoice file presented in Table 9.3. The key data fields used in calculation are Invoice Amount and Due Date. The system compares the Due Date in the record with a specified cutoff date to produce aged summaries of the Invoice Amount data. The default intervals used are 30, 60, 90, and 120 days past due. These, however, can be changed to any values that better suit the auditor’s needs.
