Chart of Accounts: The Complete Setup Guide for SMBs

What Is a Chart of Accounts?

A chart of accounts (CoA) is a complete list of every account your business uses to categorise financial transactions. Think of it as a filing system for your money - every dollar that flows through your business gets sorted into one of these accounts.

When you record a $200 purchase of printer paper, it goes into an "Office Supplies" account. When a client pays a $5,000 invoice, it goes into a "Sales Revenue" account. Your chart of accounts defines all these categories.

Why Your Chart of Accounts Matters

A well-structured chart of accounts makes everything easier:

• Accurate reporting - Your profit and loss statement and balance sheet are only as good as your categorisation. The right CoA gives you meaningful reports that actually help you make decisions.
• Easier tax compliance - When tax time comes, a properly organised CoA means your accountant can quickly find what they need. This saves time and money.
• Better insights - Want to know how much you spent on marketing last quarter? Or what percentage of revenue goes to wages? A good CoA lets you answer these questions instantly.
• Consistency - When everyone categorises transactions the same way, your financial data is reliable and comparable across periods.

The Five Main Account Types

Every chart of accounts is built around five fundamental account types:

1. Assets

Assets are things your business owns or is owed. They are divided into:

Current Assets - Cash, bank accounts, accounts receivable (money owed to you), inventory, prepaid expenses. These can be converted to cash within 12 months.

Non-Current Assets - Equipment, vehicles, property, furniture, intellectual property. These are long-term resources used to generate revenue.

2. Liabilities

Liabilities are what your business owes to others:

Current Liabilities - Accounts payable (bills you owe), credit card balances, GST/VAT collected, short-term loans, employee entitlements due within 12 months.

Non-Current Liabilities - Long-term loans, mortgages, equipment finance. These are obligations due beyond 12 months.

3. Equity

Equity represents the owner's interest in the business. This includes owner's capital, retained earnings (accumulated profits), and drawings (money taken out by owners).

4. Revenue (Income)

Revenue accounts track all the money your business earns. Common revenue accounts include sales income, service income, interest income, and other income.

5. Expenses

Expense accounts track all the money your business spends. These are usually the most numerous and include everything from rent and wages to marketing, insurance, and office supplies.

Setting Up Your Chart of Accounts

Step 1: Start with a Template

Most accounting software comes with industry-specific templates. In Xero, you can choose from templates designed for retail, services, construction, hospitality, and more. Starting with a template saves time and ensures you cover the basics.

Step 2: Customise for Your Business

Every business is different. Review the template accounts and add, remove, or rename accounts to match your operations. A cafe might need accounts for "Food Costs" and "Beverage Costs" as separate line items, while a consulting firm would not.

Step 3: Keep It Simple

A common mistake is creating too many accounts. If you have 200 expense categories, your reports become unwieldy and categorising transactions becomes confusing. Aim for enough detail to be useful, but not so much that it becomes unmanageable.

A typical small business might have 30 to 60 accounts in total. Start lean and add accounts as needed.

Step 4: Use a Numbering System

Most accounting software automatically numbers your accounts, but understanding the convention helps:

• 1000-1999: Assets
• 2000-2999: Liabilities
• 3000-3999: Equity
• 4000-4999: Revenue
• 5000-5999: Cost of Goods Sold
• 6000-6999: Operating Expenses
• 7000-7999: Other Expenses

Step 5: Set Up Account Codes

Account codes help you quickly identify and search for accounts. Keep them logical and consistent. For example, all marketing-related expenses might start with 62xx.

Common Accounts for Small Businesses

Here is a practical starting point for a typical Australian small business:

Revenue: Sales income, service income, interest income

Cost of Sales: Materials, subcontractor costs, direct labour

Operating Expenses: Advertising and marketing, bank fees, depreciation, insurance, internet and telephone, motor vehicle expenses, office supplies, professional fees (accounting, legal), rent, repairs and maintenance, subscriptions and software, travel, wages and salaries, superannuation, workers compensation

Assets: Business bank account, accounts receivable, equipment, motor vehicles

Liabilities: Accounts payable, GST collected, GST paid, PAYG withholding, credit cards, business loan

Equity: Owner's equity, retained earnings, drawings

Tips for Maintaining Your Chart of Accounts

Review annually - At least once a year, review your CoA to remove unused accounts and add any new categories you need.

Be consistent - Once you assign a transaction to a category, always assign similar transactions to the same category. Consistency is more important than perfection.

Train your team - If multiple people handle bookkeeping, make sure everyone understands which accounts to use. A simple guide with examples helps enormously.

Use automation - AI-powered tools like SortBooks learn your categorisation patterns and apply them consistently to new transactions. This eliminates the guesswork and reduces errors.

Do not change mid-year - If possible, avoid making major changes to your CoA mid-financial year. It makes year-on-year comparisons difficult. Plan changes for the start of a new financial year.

Your chart of accounts is not something you set up once and forget. It evolves with your business. But getting the foundations right from the start will save you countless hours of cleanup later.
