Accounting is the process of recording, classifying, summarizing, and interpreting financial transactions of a business.
The main objectives of accounting are:
To record financial transactions accurately
To determine profit or loss
To show the financial position of a business
To provide information for decision-making
2. Accounting Equation
The accounting equation is the foundation of accounting.
Assets = Capital + Liabilities
Where:

This equation must always remain balanced.

Sales Journal
Purchases Journal
Sales Returns Journal
Purchases Returns Journal
Cash Book
General Journal
These books help organize transactions before posting to the ledger.
5. Ledger Accounts
A ledger is a collection of accounts where transactions are recorded in detail.
Each account follows the T-account format:
Debit side (Dr) and Credit side (Cr).
Examples of ledger accounts include:
Cash account
Bank account
Sales account
Purchases account
Capital account
Ledger accounts summarize business transactions.
6. Trial Balance
A trial balance is prepared to check the accuracy of ledger accounts.
It lists all account balances at a particular date.
Key rule:
Total debits = Total credits
If totals are equal, it suggests that the double entry system has been applied correctly.
However, some errors may still exist even if the trial balance balances.
7. Errors in Accounting
Common accounting errors include:
Errors of Omission
A transaction is completely omitted from records.
Errors of Commission
A transaction is recorded in the wrong account.
Errors of Principle
Incorrect classification of capital and revenue items.
Compensating Errors
Two errors cancel each other out.
Some errors are corrected using the suspense account.

Examples include:
Sales Ledger Control Account
Purchases Ledger Control Account
Control accounts help detect errors and improve accounting efficiency.
9. Bank Reconciliation Statement
A bank reconciliation statement explains differences between:
Bank statement balance

Differences may occur due to:
Outstanding cheques
Deposits not yet recorded
Bank charges
Direct debits
Bank reconciliation helps ensure accurate cash records.
10. Depreciation of Non-Current Assets
Depreciation represents the reduction in value of non-current assets over time.
Two common methods:
Straight-Line Method
Equal depreciation each year.
Formula:
Annual Depreciation =
(Cost – Residual Value) ÷ Useful Life
Reducing Balance Method
Depreciation is calculated on the remaining value of the asset each year.
This method results in higher depreciation in earlier years.

Key calculation:

13. Accounting Ratios
Accounting ratios help analyze business performance.
Profitability Ratios
Examples:
Gross Profit Margin
Gross Profit ÷ Revenue × 100
Net Profit Margin
Net Profit ÷ Revenue × 100
Liquidity Ratios
Examples:
Current Ratio
Current Assets ÷ Current Liabilities
Quick Ratio
(Current Assets – Inventory) ÷ Current Liabilities
Efficiency Ratios
Examples:
Inventory Turnover
Cost of Sales ÷ Average Inventory
These ratios help evaluate business performance.
