This chapter examined audit procedures associated with the expenditure cycle. It began
with a review of alternative technologies used in both legacy and modern systems. The
focus was on the key operational tasks that constitute the purchases, cash disbursement,
and payroll procedures. The second section explained expenditure cycle audit objectives,
controls, and tests of controls that an auditor normally performs. Evidence from such
procedures is used to determine the nature, timing, and extent of substantive tests. The
last section described substantive tests in relation to expenditure cycle assertions based
upon ACL software applications.
