The chart of accounts (COA) is the backbone of your business’s financial system. It’s a structured list of all the accounts you use to track money in and out — like income, expenses, assets, liabilities, and equity.
At Ozobooks, we help small businesses set up and streamline their chart of accounts so everything is easy to track, report, and lodge with the ATO.
What Is a Chart of Accounts?
A chart of accounts is a listing of all financial accounts in your general ledger, grouped into categories like:
- Assets (e.g. bank, inventory)
- Liabilities (e.g. loans, GST payable)
- Equity (e.g. retained earnings)
- Income (e.g. sales, interest)
- Expenses (e.g. rent, wages, software)
Each account gets a unique code or number, making it easy to organise transactions and generate reports.
Example Layout:
| Account Code | Account Name | Type |
| 1000 | Bank Account | Asset |
| 2000 | Accounts Payable | Liability |
| 4000 | Sales | Income |
| 6000 | Rent Expense | Expense |
Why It Matters
A clear chart of accounts:
- Keeps your bookkeeping organised
- Helps produce accurate financial reports (P&L, balance sheet)
- Makes BAS lodgement and GST tracking simpler
- Is essential for year-end tax returns and audits
Without a clean COA, things like payroll, GST, and super can get misreported or missed entirely.
How We Help
At Ozobooks, we:
- Review your existing chart of accounts
- Create a COA tailored to your industry
- Set up codes for GST tracking, payroll, and compliance

- Clean up duplicates or messy account structures
FAQ:
Q1: Do I need a chart of accounts for a sole trader business?
Yes. Even sole traders benefit from having a clear structure to track income, expenses, and BAS-related items.
Q2: Can I change my chart of accounts later?
Yes, but changes should be carefully planned to avoid breaking links to past reports. We can help restructure safely.
Q3: Does Xero or MYOB come with a default COA?
Yes, but it’s often generic. We customise it for your business needs and ATO compliance.
Q4: How many accounts should I have?
Enough to track major income/expense categories, but not so many that it becomes unmanageable. 30–60 is typical.
