Chart of Accounts: Structure, Examples, and Best Practices
Definition
A Chart of Accounts (COA) is the organized listing of all accounts used by a company in its general ledger. It assigns a unique number and name to each account and groups them into categories: assets, liabilities, equity, revenue, and expenses.
How It Works
The chart of accounts provides the framework for recording all financial transactions. Each account has a unique number (typically following a standardized numbering system), a name, and a category. The numbering system usually groups accounts logically: 1000s for assets, 2000s for liabilities, 3000s for equity, 4000s for revenue, and 5000-9000s for expenses. The COA should be detailed enough to provide useful information for decision-making but not so granular that it becomes unmanageable. A well-designed COA aligns with the company's financial reporting needs and makes it easy to prepare financial statements.
Example
A typical small business COA might include: 1000 Cash, 1100 Accounts Receivable, 1200 Inventory, 1300 Prepaid Expenses, 1500 Equipment, 1510 Accumulated Depreciation, 2000 Accounts Payable, 2100 Accrued Expenses, 2500 Notes Payable, 3000 Common Stock, 3100 Retained Earnings, 4000 Sales Revenue, 4100 Service Revenue, 5000 Cost of Goods Sold, 6000 Salaries Expense, 6100 Rent Expense, 6200 Utilities Expense, 7000 Interest Expense.
Common Misconceptions
- ✗Every company uses the same chart of accounts — COAs are customized to each company's industry, size, and reporting needs. A manufacturing company's COA looks very different from a service company's.
- ✗The chart of accounts is set once and never changes — COAs evolve as the business grows. New accounts are added for new activities, and unused accounts may be consolidated or removed.
- ✗Account numbers don't matter — the numbering system is critical for organization, sorting, and financial reporting. A logical numbering scheme makes it easy to find accounts and group them for statements.

Common questions about Chart of Accounts
There's no fixed number. A sole proprietorship might have 20-30 accounts. A small business might have 50-100. A large corporation might have thousands. The key is having enough detail for useful reporting without creating unnecessary complexity.
A common system: 1000-1999 for Assets, 2000-2999 for Liabilities, 3000-3999 for Equity, 4000-4999 for Revenue, 5000-5999 for Cost of Goods Sold, 6000-6999 for Operating Expenses, 7000-7999 for Other Income/Expenses. Sub-accounts use additional digits.
Yes, but changes should be made carefully. Adding new accounts is straightforward. Removing or renaming accounts can affect historical reporting and should be done at the start of a new fiscal period. Most accounting software allows you to make accounts inactive rather than deleting them.
