Dual aspect concept definition
/What is the Dual Aspect Concept?
The dual aspect concept states that every business transaction requires recordation in two different accounts. This concept is the basis of double entry accounting, which is required by all accounting frameworks in order to produce reliable financial statements. The concept is derived from the accounting equation, which states that:
Assets = Liabilities + Equity
The accounting equation is made visible in the balance sheet, where the total amount of assets listed must equal the total of all liabilities and equity. One part of most business transactions will have an impact in some way on the balance sheet, so at least one part of every transaction will involve either assets, liabilities, or equity.
If management wants to have its financials audited, it must accept the dual aspect concept and maintain its accounting records using double-entry accounting. This is the only format that auditors will accept if they are to issue opinions on financial statements.

Examples of the Dual Aspect Concept
Here are several examples of the dual aspect concept:
Issue an invoice to a customer. One part of the entry increases sales, which appears in the income statement, while the offset to the entry increases the accounts receivable asset in the balance sheet. In addition, the change in income triggered by the increase in sales appears in retained earnings, which is part of the equity section of the balance sheet.
Receive an invoice from a supplier. One part of the entry increases an expense or an asset account, which can appear in either the income statement (for an expense) or in the balance sheet (for an asset). The offset to the entry increases the accounts payable liability in the balance sheet. In addition, the change in income triggered by the recordation of an expense appears in retained earnings, which is part of the equity section of the balance sheet.
Single-Entry Accounting
If an organization were not to observe the dual aspect concept, it would use single-entry accounting, which is essentially a checkbook. A checkbook cannot be used to derive a balance sheet, so an entity would be limited to the construction of a cash-basis income statement.
Single-Entry vs. Dual-Aspect Accounting
The single-entry system, as the name implies, requires you to make a single entry for any accounting transaction. This is essentially an entry into a checkbook. Dual-aspect accounting requires that you make two entries for every transaction. One difference between these approaches is that you can create a balance sheet if you are using dual-aspect accounting, but not when you are using the single-entry system. Another difference is the lower level of accounting knowledge required for the single-entry system, whereas some bookkeeping expertise is required to use the dual-aspect system. A further difference is that auditors will not certify the financial statements of a business that uses the single-entry system, while they will do so when a dual-aspect system is in place.
