Historical Context
Double-entry bookkeeping has a rich history that dates back to the 15th century. The system was first documented by the Italian mathematician and Franciscan friar Luca Pacioli, known as the “Father of Accounting and Bookkeeping.” In his 1494 book Summa de Arithmetica, Geometria, Proportioni et Proportionalità, Pacioli described the use of journals and ledgers to maintain accounts, a practice that became the standard in business accounting.
The Core Rules
In double-entry bookkeeping, every financial transaction impacts at least two accounts, ensuring the accounting equation \(\text{Assets} = \text{Liabilities} + \text{Equity}\) remains balanced. The fundamental rules for recording these transactions are:
-
Asset Accounts:
- Increase: Debit
- Decrease: Credit
-
Expense Accounts:
- Increase: Debit
- Decrease: Credit
-
Liability Accounts:
- Increase: Credit
- Decrease: Debit
-
Revenue Accounts:
- Increase: Credit
- Decrease: Debit
-
Capital (Equity) Accounts:
- Increase: Credit
- Decrease: Debit
Types and Categories
- Assets: Cash, Accounts Receivable, Inventory, Property.
- Liabilities: Loans Payable, Accounts Payable, Mortgages.
- Equity: Owner’s Capital, Retained Earnings.
- Revenues: Sales Revenue, Interest Income.
- Expenses: Rent Expense, Salaries, Utilities.
Key Events
- 1494: Luca Pacioli documents double-entry bookkeeping in his book.
- Early 1800s: Adoption of double-entry accounting principles spreads globally.
- 2002: Introduction of International Financial Reporting Standards (IFRS) which reinforced the application of these principles globally.
