This chapter examines audit procedures associated with the expenditure
cycle. This chapter is divided into three main sections. It begins with a
review of computer technologies used in both legacy and modern systems. The
focus is on the way that key operational tasks are performed under different
technological environments. The second section discusses the expenditure cycle
audit objectives, controls, and tests of controls that an auditor would normally
perform to gather the evidence needed to limit the scope, timing, and extent of
substantive tests. The last section describes substantive tests in relation to expenditure
cycle audit objectives that can be performed using ACL software.
