The study of accounting information systems (AISs) is, in large part, the study
of the application of information technology (IT) to accounting systems. This chapter
describes the ways that information technology affects financial accounting, managerial
accounting, auditing, and taxation. We begin by answering the question ‘‘what are
accounting information systems’’ and then look at some new developments in the field.
Following this, we will examine some traditional roles of AISs in commerce.
