One of the most important financial decisions a business owner makes is how to record income and expenses. There are two methods: cash accounting and accrual accounting. Both are widely used and accepted by the ATO. But they work differently, and choosing the wrong one can make your records harder to understand and manage over time.
This article explains how each method works, where each one falls short, and how to work out which one fits your business.
What Is Cash Accounting?
Cash accounting is the simpler of the two methods. You record income when you receive a payment. You record an expense when you make a payment. Nothing is recorded until money actually changes hands. Think of it like tracking a personal bank account. Money comes in, you note it. Money goes out, you note it. There are no invoices sitting in the middle waiting to be counted.
Example: You finish a project in March and send the invoice. Your client pays in April. With cash accounting, that income goes into April’s records, not March. Your March books show nothing for that job.
This method is straightforward and gives you a clear view of how much money you actually have at any point in time.
What Is Accrual Accounting?
Accrual accounting works differently. You record income when it is earned, not when you get paid. You record an expense when it is incurred, not when you settle the bill. The principle behind it is simple: income and expenses belong to the period they happened in, not the period the cash moved.
Example: You finish a project in March and send the invoice. Your client pays in April. With accrual accounting, that income goes into March’s records, because that is when you did the work and earned the money.
This method gives a fuller picture of your business at any given time. It captures what you are owed and what you owe, even when no cash has moved yet.
The Key Difference
Both methods come down to one question: when does a transaction get recorded?
With cash accounting, it is recorded when cash changes hands. With accrual accounting, it is recorded when the transaction occurs, whether or not money has moved. This timing difference sounds minor, but over the course of a month or a full financial year, it can produce very different financial statements from the same business activity.

Cash Accounting: Benefits and Limitations
Benefits
- Simple to manage. There is no need to track unpaid invoices or outstanding bills. You record what comes in and what goes out. Most small business owners can manage this without specialist software or a dedicated bookkeeper.
- You always know your cash position. Because your records closely match your bank activity, you can see exactly how much money you have available at any time. There is no gap between what your books say and what you can spend.
- Lower cost to run. Cash-based records take less time to maintain and often do not require professional help to keep up to date. For a sole trader or small operator, this can make a real difference to overheads.
- Simpler end-of-year reporting. Because you only record money you have actually received, pulling your year-end figures together is more straightforward.
Limitations
- It can give a misleading picture of performance. If you complete a lot of work in one month but clients pay the following month, your records will not reflect the activity accurately. A productive month can look flat on paper, while a quieter month can look strong simply because old invoices were settled. This can make it difficult to spot real trends in your business.
- Not suitable for every business model. If you offer credit to customers, carry stock, or deal with deferred payments regularly, cash accounting does not capture the full picture of what is owed or owned at any point in time.
- Harder to plan ahead. Because you can only see what has already come in, forecasting becomes less reliable. If you are thinking about how to build a business budget that actually holds , this is worth factoring into your decision.
Accrual Accounting: Benefits and Limitations
Benefits
- More accurate financial reports. Income and expenses are matched to the periods they belong to. Your monthly reports reflect what actually happened during that period, not just what got paid. This makes it easier to compare performance across months and years.
- Better for planning and decision-making. Because you can see what you are owed and what you owe at any time, you have a more reliable base for planning spending, managing growth, and identifying issues early.
- Preferred by banks and investors. When you apply for a business loan or present financials to outside parties, accrual-based statements carry more weight. They give a clearer and more credible view of financial health. Understanding what financial statements lenders typically review can help you prepare if that is something you are working towards.
- Grows with your business. As your transactions become more varied and complex, accrual accounting handles them more cleanly. It is built to scale in a way that cash accounting is not.
Limitations
- More work to maintain. You need to track accounts receivable and accounts payable on an ongoing basis. This takes more time and generally requires accounting software and, in most cases, a bookkeeper or accountant.
- Profit and cash can look very different. You might report strong earnings while having little cash available, particularly if clients are slow to pay. This is normal under accrual accounting, but it means you need to track cash flow separately from your profit figures. Knowing the difference between profit and cash flow in your business becomes important here.
- Higher running costs. The added complexity usually means you need professional support to manage it properly. That is an ongoing cost to factor into your decision.
Which Businesses Tend to Use Each Method?
Cash accounting works well for:
- Sole traders and freelancers
- Small service-based businesses that get paid at the time of work
- Retail and hospitality businesses with simple, high-volume transactions
- New businesses in the early stages of trading
- Businesses with low transaction volumes and no outstanding invoices
Accrual accounting works well for:
- Businesses that invoice clients and offer payment terms
- Businesses that carry stock or inventory
- Businesses with staff and regular payroll obligations
- Businesses planning to apply for funding or seek investment
- Businesses with more complex or varied transactions
The right method is not always about size. A small business that sends a lot of invoices and regularly waits 30 to 60 days for payment may benefit from accrual accounting long before turnover reaches a level that requires it.
What the ATO Requires
In Australia, businesses with a GST turnover under $10 million can generally choose either method for BAS reporting. Businesses above $10 million are required to use accrual accounting.
It is also possible to use different methods for different purposes. Some businesses use cash reporting for GST while maintaining accrual-based accounts internally. The rules around this depend on your business structure. Speaking with an accountant is the most reliable way to confirm what applies to you.
Common Mistakes to Watch Out For
- Mixing methods without realising it. Applying cash accounting to some transactions and accrual to others creates inconsistencies that are difficult to fix later. Whichever method you choose, apply it consistently across all transactions.
- Confusing profit with available cash. This comes up most often with accrual accounting. Your reports may show solid earnings while your bank balance is low because payments are still outstanding. Monitoring both figures separately is important.
- Switching methods without planning. Changing from one method to the other mid-year, without carefully accounting for existing invoices and bills, can result in transactions being counted twice or missed. The best time to switch is at the start of a new financial year, with support from an accountant who can manage the adjustments.
- Leaving the decision too late. Setting up your accounting method after you have already started trading creates extra work to correct your records. It is much easier to choose the right method from the start, particularly when you are still setting up your business finances for the first time.
Making the Right Call for Your Business
Cash and accrual accounting are both workable approaches. Neither is right for every business. The best choice depends on how your business operates, how you get paid, and what you need your financial records to tell you.
If your business is small, simple, and mostly paid upfront, cash accounting is a practical choice that keeps things manageable. If you invoice clients, carry stock, employ staff, or need detailed financial reports, accrual accounting will give you a more reliable view of how your business is actually going.
