Double entry system definition

What is the Double Entry System?

The double entry system mandates that every business transaction be recorded in at least two accounts. Furthermore, it requires that the total value of all debits entered in a transaction must batch the total value of all credits; otherwise, a journal entry is said to be out of balance. These rules are needed to ensure that a business always keeps its accounting equation properly balanced. For example, a debit of $1,000 to an asset account may be balanced by a credit of $1,000 to a liability account. The accounting equation is as follows:

Assets = Liabilities + Equity

Advantages of a Double Entry System

The key advantage of a double entry system is that it allows an organization to produce a full set of financial statements. In particular, it can create a balance sheet, which cannot be produced with just a single entry system. With complete financial statements, it is much easier for a business to convince investors to invest money in it.

Disadvantages of a Double Entry System

There are several disadvantages to using a double entry system. First, it is more complex to use, and so is generally avoided by smaller businesses that cannot afford to hire anyone with accounting expertise. Second, the need for accounting expertise means that a double entry system is more expensive to operate, which is a nonstarter for businesses that are already losing money. And third, it takes more time to close the books properly at the end of each reporting period, which can delay the production of financial statements.

Example of the Double Entry System

The Grouch Electronics company sells a $5,000 home entertainment installation to a client on credit. This results in a debit of $5,000 of the company’s accounts receivable account and a credit of $5,000 to its sales account. Later, the customer pays the $5,000 invoice, at which point the company records a debit of $5,000 to its cash account and a credit of $5,000 to its accounts receivable account. The end result of these transactions is a sale of $5,000 and an increase in cash of $5,000.
