1. Accounting Equation
The accounting equation is fundamental in double-entry bookkeeping. It shows the relationship between assets, liabilities, and owner’s equity. The equation is:
Assets = Liabilities + Owner’s Equity
This means that everything a business owns (assets) is financed either by borrowing money (liabilities) or by the owner’s investment (equity). The equation must always balance.
2. Double Entry Principle
The double entry principle ensures that every transaction has an equal and opposite effect on at least two accounts. This principle maintains the balance in the accounting equation. For example, when a business buys goods on credit, it increases both inventory (asset) and accounts payable (liability).
- Example:
- Debit: Inventory (Asset increases)
- Credit: Accounts Payable (Liability increases)
This is an example of applying the double-entry principle, where each transaction has a debit entry and a corresponding credit entry.
3. Source Documents
Source documents are original records that provide evidence of a financial transaction. These documents support the accuracy of the transactions recorded in the books. Some common source documents include:
- Invoice: A document requesting payment for goods or services.
- Receipt: Proof of payment made by the business.
- Bank Statement: A document from the bank that shows all transactions in a business’s bank account.
4. Subsidiary Books
Subsidiary books are used to record specific types of transactions before they are posted into the general ledger. Types of subsidiary books include:
- Sales Day Book: Records all credit sales.
- Purchases Day Book: Records all credit purchases.
- Cash Book: Records all cash transactions, both receipts and payments.
- Journal: Records transactions that do not fit into the other books, such as adjustments.

Class Activity Discussion (FAQs with Answers)
- What is the original accounting equation, and why is it important?
Answer: The original accounting equation is Assets = Liabilities + Equity. This equation is fundamental to accounting because it ensures that every financial transaction is properly recorded, maintaining the balance between what the business owns (assets), what it owes (liabilities), and the owners’ equity. - What is the double-entry principle, and how does it apply to accounting?
Answer: The double-entry principle states that every transaction affects at least two accounts in opposite ways—one account is debited and another is credited with equal amounts. This ensures the accounting equation remains balanced and helps avoid errors. - What are source documents, and what role do they play in accounting?
Answer: Source documents are original records, such as invoices, receipts, and contracts, that provide evidence and details for business transactions. They are essential for verifying transactions, ensuring accuracy in financial records, and serving as the foundation for accounting entries. - What is the purpose of subsidiary books in accounting?
Answer: Subsidiary books are used to record specific types of transactions, such as sales, purchases, cash payments, and receipts. They help organize transactions in a systematic manner before they are transferred to the general ledger. - Can you give examples of subsidiary books and what they record?
Answer: Examples of subsidiary books include:- Sales Journal: Records credit sales of goods and services.
- Purchases Journal: Records credit purchases of goods and services.
- Cash Book: Records all cash transactions, both payments and receipts.
- Sales Returns Journal: Records goods returned by customers.
- Purchases Returns Journal: Records goods returned to suppliers.
- Why is the double-entry system considered the foundation of accounting?
Answer: The double-entry system is essential because it ensures that the accounting equation remains balanced and that every transaction is accurately recorded. By recording both the debit and credit sides of a transaction, the system prevents errors and fraud. - How do source documents influence the accuracy of financial reporting?
Answer: Source documents provide the original and authentic details of a transaction, ensuring that financial entries are accurate and reliable. Without these documents, financial records would lack the necessary evidence to support transactions. - What happens if the double-entry principle is not followed in accounting?
Answer: If the double-entry principle is not followed, the accounting equation will not balance, leading to inaccurate financial records. This could result in errors in financial statements, which may affect business decisions and financial reporting. - What are the benefits of using subsidiary books in accounting?
Answer: Subsidiary books help streamline the accounting process by categorizing transactions, making it easier to record, track, and analyze business activities. They also reduce errors and improve the efficiency of the accounting system. - How does the accounting equation reflect the financial health of a business?
Answer: The accounting equation provides a snapshot of a business’s financial position by showing the relationship between assets, liabilities, and equity. A balanced equation indicates that the business’s financial records are accurate and that it is managing its finances properly.
