Double Entry Accounting: The Language of Business

May 22, 2023

Double entry accounting is a system of recording financial transactions in which every transaction is recorded in two accounts. This system is used by businesses of all sizes to track their financial activity and to prepare accurate financial statements.

The basic principles of double entry accounting are as follows:

  • Every transaction has two effects. When a transaction occurs, it affects at least two accounts. For example, if a business buys a computer for $1,000, the cash account will decrease by $1,000 and the computer equipment account will increase by $1,000.
  • Debits increase assets and expenses. Debits are recorded on the left side of an account. Assets and expenses are increased by debits.
  • Credits increase liabilities, equity, and revenue. Credits are recorded on the right side of an account. Liabilities, equity, and revenue are increased by credits.

The sum of all debits must equal the sum of all credits for every transaction. This is known as the accounting equation.

The Dual Effect of Transactions

The dual effect of transactions is the concept that every transaction affects at least two accounts. For example, when a business sells a product for $100, the cash account will increase by $100 and the sales account will increase by $100. The sales account is increased because the business has earned revenue, and the cash account is increased because the business has received cash.

The dual effect of transactions can be seen in all types of business transactions. Here are some examples:

  • Cash sale: When a business sells a product for cash, the cash account will increase and the sales account will increase.
  • Credit sale: When a business sells a product on credit, the accounts receivable account will increase and the sales account will increase.
  • Purchase of inventory: When a business buys inventory for cash, the cash account will decrease and the inventory account will increase.
  • Purchase of inventory on credit: When a business buys inventory on credit, the accounts payable account will increase and the inventory account will increase.
  • Payment of expenses: When a business pays an expense, the cash account will decrease and the expense account will increase.
  • Receipt of payment from a customer: When a business receives payment from a customer, the cash account will increase and the accounts receivable account will decrease.

The Accounting Equation

The accounting equation is a mathematical equation that shows the relationship between a business’s assets, liabilities, and equity. The equation is as follows:

Assets = Liabilities + Equity

Assets are things that a business owns, such as cash, inventory, and equipment. Liabilities are things that a business owes to others, such as accounts payable and loans. Equity is the difference between a business’s assets and liabilities. It represents the ownership interest of the business’s owners.

The accounting equation must always be in balance. This means that the total assets of a business must always equal the total liabilities plus the total equity.

The Benefits of Double Entry Accounting

Double entry accounting has many benefits for businesses. These benefits include:

  • Accuracy: Double entry accounting is a very accurate way to record financial transactions. This is because every transaction is recorded in two accounts, which helps to prevent errors.
  • Completeness: Double entry accounting ensures that all financial transactions are recorded. This is because every transaction affects at least two accounts, so it is impossible to forget to record a transaction.
  • Timeliness: Double entry accounting helps businesses to keep their financial records up to date. This is because transactions are recorded as they occur, which helps businesses to make informed financial decisions.
  • Compliance: Double entry accounting is required by many government agencies. This is because it provides a clear and accurate picture of a business’s financial activity.

Conclusion

Double entry accounting is a powerful tool that can help businesses to improve their financial reporting and decision-making. If you are a business owner, you should consider implementing double entry accounting in your business.
