🎯 Learning Objectives
By the end of this module, you will be able to:
- Understand the structure and purpose of a General Ledger (GL)
- Explain the difference between debit and credit entries
- Recognize GL account hierarchies and chart of accounts
- Identify the types of GL accounts and their normal balances
- Apply basic GL posting principles to common transactions
1. What is a General Ledger?
The General Ledger (GL) is the primary accounting record of a company. It contains all transactions posted to an organization's accounts during a specific period. The GL serves as the foundation for creating financial statements and reports.
💡 Key Definition
General Ledger: A master accounting record containing all accounts and their balances for a business. All individual transactions flow into the GL, which then feeds into the financial statements (Balance Sheet, Income Statement, Cash Flow Statement).
Why is the GL Important?
- Accuracy: Ensures all transactions are properly recorded
- Compliance: Required for internal controls and audits
- Reporting: Provides data for financial and management reports
- Analysis: Enables variance analysis and performance tracking
- Reconciliation: Supports monthly reconciliation processes
2. Chart of Accounts
The Chart of Accounts (CoA) is the complete list of all GL accounts available in an organization. Each account has a unique account code and is classified by account type.
Account Hierarchy
Example: R2R Account Structure
1000 - ASSETS
├── 1100 - Cash
│ ├── 1110 - Cash on Hand
│ └── 1120 - Bank Accounts
├── 1200 - Accounts Receivable
│ ├── 1210 - AR - Domestic
│ └── 1220 - AR - International
└── 1300 - Inventory
├── 1310 - Raw Materials
├── 1320 - Work in Progress
└── 1330 - Finished Goods
2000 - LIABILITIES
├── 2100 - Accounts Payable
├── 2200 - Accrued Expenses
└── 2300 - Deferred Revenue
3000 - EQUITY
├── 3100 - Common Stock
└── 3200 - Retained Earnings
4000 - REVENUE
├── 4100 - Product Revenue
└── 4200 - Service Revenue
5000 - EXPENSES
├── 5100 - Cost of Goods Sold
├── 5200 - Operating Expenses
└── 5300 - Administrative Expenses
3. Account Types and Normal Balances
Each GL account has a classification and a normal balance side (debit or credit). Understanding account types is critical for accurate GL posting.
| Account Type | Normal Balance | Increases By | Decreases By | Example |
|---|---|---|---|---|
| Asset | Debit | Debit | Credit | Cash, AR, Inventory |
| Liability | Credit | Credit | Debit | AP, Accrued Exp |
| Equity | Credit | Credit | Debit | Stock, Retained Earnings |
| Revenue | Credit | Credit | Debit | Sales, Service Revenue |
| Expense | Debit | Debit | Credit | COGS, Salaries, Rent |
📌 Golden Rule of Accounting
Every transaction must maintain the fundamental equation: Assets = Liabilities + Equity
For every debit entry, there must be a corresponding credit entry of equal amount (Double-Entry Accounting).
4. Basic GL Posting Principles
Principle 1: Double-Entry Accounting
Every transaction is recorded in at least two GL accounts—one account is debited, and another is credited. This ensures the accounting equation remains balanced.
Example 1: Cash Sale of $1,000
GL Posting:
Debit: 1110 - Cash on Hand $1,000
Credit: 4100 - Product Revenue $1,000
Principle 2: Matching Amounts
The total debits must equal the total credits. If they don't match, there's a posting error.
Example 2: Purchase Inventory on Credit for $5,000
GL Posting:
Debit: 1330 - Finished Goods $5,000
Credit: 2100 - Accounts Payable $5,000
Check: Total Debits ($5,000) = Total Credits ($5,000) ✓
Principle 3: Proper Account Selection
Use the correct GL account code for each transaction. Wrong account selection leads to inaccurate reports and analysis.
5. Common GL Posting Errors
- Wrong Account Code: Posting to 1110 instead of 1120 for bank deposits
- Reversed Entry: Debiting when you should credit, or vice versa
- Incorrect Amount: Posting $1,000 instead of $10,000
- Missing Entry: Posting only the debit and forgetting the credit (out-of-balance)
- Duplicate Posting: Posting the same transaction twice
6. GL Posting Workflow
- 🔍 Review: Analyze the transaction and understand its nature
- 🎯 Identify Accounts: Determine which GL accounts are affected
- ➕ Determine Debits/Credits: Decide which account(s) to debit and credit
- ✍️ Post Entries: Record the GL entries in the accounting system
- ✓ Verify: Confirm that debits equal credits (trial balance)
- 📊 Report: Use GL data to create financial statements
✏️ Interactive Exercise
Scenario: Your company received a customer payment of $2,500 for services rendered. Which accounts should be debited and credited?
✓ Correct Answer: Debit: 1110 - Cash on Hand, Credit: 4200 - Service Revenue
