Fundamental Accounting Principles

▪ Accrual Principle

Revenues and expenses are recorded when they are earned or incurred, not when cash is received or paid.

▪ Consistency Principle

The same accounting policies should be applied consistently to ensure comparability over time.

▪ Matching Principle

Expenses should be matched with the revenues they generate in the same accounting period.

▪ Prudence (Conservatism) Principle

Potential losses should be recognized, while profits should not be overstated.


▪ Going Concern Principle

The business is assumed to continue operating in the foreseeable future.

The Accounting Cycle

Financial transactions go through a series of steps known as the accounting cycle:

  1. Occurrence of a financial transaction

  2. Recording the journal entry

  3. Posting to the general ledger

  4. Preparing the trial balance

  5. Making adjusting entries

  6. Preparing financial statements

  7. Closing the accounts

Journal Entries

Journal entries are the foundation of accounting and are based on the rule:

Every transaction has a debit and a credit.

Example:

  • Purchasing inventory with cash

    • Debit: Inventory

    • Credit: Cash

Chart of Accounts

The chart of accounts is the structure used to classify accounts, including:

  • Assets

  • Liabilities

  • Equity

  • Revenues

  • Expenses

A well-designed chart of accounts is essential for accurate financial reporting.


Core Financial Statements

1) Income Statement

Shows:

  • Revenues

  • Expenses

  • Net profit or loss

2) Balance Sheet

Shows:

  • Assets

  • Liabilities

  • Equity


3) Cash Flow Statement
