An accounting system consists of the methods and devices used by an entity to keep track of its financial activities and to summarize these activities in a manner useful to decision makers. Regardless of whether the accounting system is simple or not, three basic steps must be performed as data concerning financial activities are collected and processed—the data must be recorded, classified, and summarized.
Recording financial activity. The first function of the accounting system is to create a systematic record of the daily business activity, in terms of money. For example, goods and services are purchased and sold, credit is extended to customers, debts are incurred, and cash is received and paid out. These transactions are typical of business events which can be expressed in monetary terms, and must be entered in accounting records.
Classifying data. A complete record of all business activities usually amounts to a huge volume of data — too large and diverse to be useful to decision makers such as managers and investors. Therefore, the data must be classified into related groups or categories of transactions. For example, grouping together those transactions in which cash is received or paid out is a logical step in developing useful information about the cash position of the business.
Summarizing the data. To be useful to decision makers, accounting data must be highly summarized. The employees responsible for ordering merchandise need sales information summarized by product. Store managers will want sales information summarized by departments. Outsiders, such as the company's stockholders and the InternalRevenue Service, probably will be most interested in a single sales figure which represents the total sales of the entire company.
These three steps we have described — recording, classifying, and summarizing — are the means of creating accounting information. However, the accounting process includes more than the creatingof information. It also involves communicating this information to interested parties and interpreting accounting information to help in the making of specific business decisions.
