Double-entry bookkeeping is an accounting system where every financial transaction is recorded in at least two different accounts. For each transaction, there must be:
- A debit entry in one account
- A credit entry in another account
- The total debits must equal the total credits
For example, when a business purchases equipment for $5,000 in cash:
- Equipment account is debited $5,000 (asset increase)
- Cash account is credited $5,000 (asset decrease)
-
Error Detection: Because debits must equal credits, mathematical errors become immediately apparent when accounts don't balance.
-
Complete Financial Picture: It captures both where money came from and where it went, providing a comprehensive view of financial standing.
-
Foundation for Financial Statements: It enables the creation of accurate balance sheets and income statements that properly reflect a company's financial position.
-
Audit Trail: It creates a clear record that can be followed and verified, which is essential for auditing and compliance.
-
Asset and Liability Tracking: It properly tracks what a company owns (assets) and what it owes (liabilities).
Without double-entry bookkeeping, businesses would struggle to maintain accurate financial records, detect errors, or generate reliable financial statements that investors, regulators, and managers need for decision-making.
Top 10 Beginner Double-Entry Bookkeeping FAQs
1. Why do debits have to equal credits?
Answer: Debits equaling credits maintains the accounting equation (Assets = Liabilities + Equity). This balance ensures that all resources are properly accounted for and the financial position is accurately represented. It's the foundation of the double-entry system that prevents mathematical errors.
2. How do I know which account to debit and which to credit?
Answer: Follow these rules:
When in doubt, analyze how the transaction affects the accounting equation.
3. What's the difference between accrual and cash accounting?
Answer: Cash accounting records transactions only when cash changes hands. Accrual accounting records transactions when they occur economically, regardless of when cash moves. Accrual better reflects business performance by matching revenues with related expenses in the same period.
4. What is a journal entry?
Answer: A journal entry is the initial recording of a transaction, showing all accounts affected with their respective debits and credits. It includes the date, accounts involved, amounts, and often a brief description explaining the transaction's purpose.
5. What is a trial balance?
Answer: A trial balance is a worksheet listing all accounts with their debit or credit balances to verify that total debits equal total credits. It's typically prepared at the end of an accounting period to check for mathematical accuracy before creating financial statements.
6. How do adjusting entries work?
Answer: Adjusting entries update accounts at period-end to ensure revenues and expenses are recognized in the correct period. Common adjustments include:
7. What happens when I make an accounting error?
Answer: For errors that don't affect the trial balance (like recording to wrong accounts), make a correcting entry. For errors that do affect the trial balance, find and fix the specific mistake. Never erase or delete entries; always correct with proper documentation.
8. What's the difference between the general journal and general ledger?
Answer: The general journal chronologically records all transactions with debits, credits, and explanations. The general ledger organizes these entries by account, showing running balances. Entries are first recorded in the journal, then posted (transferred) to the ledger.
9. How do closing entries work?
Answer: Closing entries transfer balances from temporary accounts (revenue, expense, dividend) to permanent accounts (retained earnings) at period-end. This process:
10. What's the difference between a balance sheet and income statement?
Answer: The balance sheet shows the company's financial position (assets, liabilities, equity) at a specific point in time. The income statement shows performance (revenues, expenses, profit/loss) over a period of time. The balance sheet is cumulative, while the income statement covers only the specified period.
