An accounting information system (AIS)
is the system of records a business keeps to maintain its accounting system. This includes the purchase, sales, and other financial processes of the business. The purpose of an AIS is to accumulate data and provide decisions makers (investors, creditors, and managers) with information to make decisions. While this was previously a paper-based process, most modern businesses now use accounting software.
In an Electronic Financial Accounting system the steps in accounting cycle are dependent upon the system itself. Example: some systems allow direct journal posting to the various ledgers and others do not.
