Definition of Double-Entry Bookkeeping

Double-entry bookkeeping is an accounting system where every financial transaction is recorded in at least two accounts: one as a debit and the other as a credit. This method ensures that the accounting equation (Assets = Liabilities + Equity) remains balanced, improving financial accuracy and transparency.

For example, if a business buys office equipment for $5,000 using cash, the transaction is recorded as:

• Debit: Equipment Account (+$5,000)
• Credit: Cash Account (-$5,000)

Purpose of Double-Entry Bookkeeping in Accounting

This system is used to:

• Ensure financial accuracy by balancing every transaction.
• Prevent errors and fraud by maintaining accountability.
• Provide a clear financial picture for businesses and investors.
• Comply with accounting standards, such as IFRS and GAAP.
• Support financial decision-making by tracking income, expenses, and assets.

How Double-Entry Bookkeeping Works

Basic Principles

• Each transaction affects at least two accounts (one debit, one credit).
• Total debits must equal total credits to maintain balance.
• Debits increase assets and expenses, while credits increase liabilities, equity, and revenue.

Example Transaction

A company takes a $20,000 loan from a bank. The transaction is recorded as:

• Debit: Cash Account (+$20,000)
• Credit: Loan Payable Account (+$20,000)

This ensures that both sides of the accounting equation remain balanced.

Double-Entry Bookkeeping Accounts

Asset Accounts (Increase with Debits)

• Cash – Money held by the business.
• Accounts Receivable – Money owed by customers.
• Inventory – Goods available for sale.

Liability Accounts (Increase with Credits)

• Accounts Payable – Money owed to suppliers.
• Loans Payable – Business debt obligations.
• Accrued Expenses – Unpaid expenses recorded as liabilities.

Equity Accounts (Increase with Credits)

• Owner’s Equity – The owner's financial interest in the business.
• Retained Earnings – Profit reinvested in the business.
• Common Stock – Shareholder contributions in corporations.
