A Beginner’s Guide to Double-entry Accounting

Double-entry accounting means at least two entries for every accounting transaction. The practice leads to the balancing act of debits and credits. The double-entry system follows the principle of the basic accounting equation. It leads to the accuracy accounting function where all debits and credits must equal at any given time.

There are several types of double-entry accounting systems. It offers several advantages to the users. However, it requires accounting knowledge and skills to pursue that some individuals and small businesses may not be available. Let us discuss the key concepts of double-entry accounting with the help of some simple examples.

What is Double entry Accounting?

A double-entry is an accounting system that requires at least two entries for every transaction. It means there will be at least one debit and one credit entry for each transaction recorded. There is no limit to the maximum number of accounts under double-entry accounting. However, each transaction must have at least entries in two accounts.

In simple words, the double-entry concept means for every entry into one account, there must be an equal and corresponding entry into another. It means for one or more debit entries there should be one or more credit entries.

How Does Double-entry Accounting Work?

The modern accounting system relies on double-entry bookkeeping practices. Each transaction here is recorded in terms of debits and credits.

For recording purposes, the debit is recorded on the left side, and the credit is recorded on the right side. These accounts depict the financial accuracy of an entity at any given time.

The Accounting Equation

The double-entry accounting system follows the principle of the accounting equation.

Assets = Liabilities + Equity

The basic equation follows that the accounting balance of all debits must equal the balance of all credit at all times.

In accounting, a debit has the following features:

  • The portion of a transaction that increases an asset or an expense account.
  • It decreases the liability or an income account.
  • Recorded on the left side of the journal.

Similarly, credit has the following features:

  • The portion of a transaction that increases a liability or an income account.
  • It decreases the asset or expense account.
  • It is recorded on the right side of the journal.

Difference Between Single-Entry and Double-entry Accounting

Individuals, sole proprietors, and small businesses follow the single-entry accounting system. It does not require a balancing act for each transaction.

It means the single accounting system may not portray a balanced financial position of the user. Also, it is difficult to follow and reconcile accounts under the single-entry accounting system.

The biggest advantage of the single-entry system is its simplicity. However, it is only suitable for users with limited accounting requirements.

General Ledger and Double-entry Accounting

The general ledger is the books of accounts for an accounting system. It follows and represents the same accounting principles as double-entry bookkeeping does.

The general ledger of an entity forms the basis of the accounting function. It keeps a record of each account used by an entity separately. Each journal account is then reconciled and taken forward to the trial balance records.

The figures from the trial balances are then used to create the business’s financial statements. Thus, the accuracy of the general ledger through double-entry accounting leads to the accuracy of the financial statements.

It means an accurate and consistent double-entry accounting function will lead to a consistent ledger and eventually accurate financial statements of a business.
