For instance, a compliance audit might assess whether a company is meeting all necessary health and safety standards.
A compliance audit may check various documents, including:
- Company policies and procedures manuals
- Licenses and permits relevant to the business operations

Here’s a more in-depth step-by-step guide to help you navigate the process effectively.
1. Prepare for the audit
Before you do anything else, you should prepare your business for an audit. It’s important to communicate to your team that an audit will be taking place and what aspects of the company you plan to review.
During the preparation stage, make sure to define your objectives and determine the scope of the audit. Do you need a comprehensive evaluation? Is your goal to look only at a specific aspect, like finance or operations? Ensure clarity before starting.
Finally, set a timeline for the audit and get started.
2. Review financial statements
If financial review is part of your process, then the first step is to take an in-depth look at your financial statements. This involves analysing your profit and loss statement, balance sheet, and cash flow statements. These documents provide a comprehensive view of your business’s financial health.
To make this process easier, use financial software to generate these statements. Look for trends, anomalies, or areas where costs can be optimised. Ensure all transactions are accurately recorded and reconciled.
3. Assess income and expenses
Once you have a general picture of your financial health, take a closer look at income and expenses. Identify any inconsistencies or unnecessary spending in your income and expense records.
Next, categorise expenses to pinpoint areas of high spending. Consider implementing cost-saving measures, such as renegotiating contracts with suppliers or reducing non-essential expenses to cut overall costs.
4. Check tax compliance
If you want to avoid costly penalties, it’s important to ensure that you’re properly lodging your taxes. To do so, review your GST and BAS lodgments to make sure they are correct. Also, check that all deductions are properly claimed and reported.
You can use tax software to streamline the process and ensure accuracy. Plus, it’s important to regularly review tax laws and updates to avoid missing deductions or incorrectly claiming expenses.
5. Evaluate business operations
Next, you may want to assess the efficiency of your business processes. The specific steps will depend on the type of business you run. For example, if you sell products, check your inventory management and supplier payments. Meanwhile, a consulting business might look at process efficiency and current contracts.
Ultimately, you should identify areas for improvement – whether in terms of cost, efficiency, or delivery quality.
6. Identify potential risks
An important and overlooked step is to identify potential risks so you can mitigate them. Look for late payments, outstanding debts, or non-compliance issues that could pose risks to your business.
Upon review, set up reminders for payment deadlines and maintain open communication with creditors. You should also regularly review compliance with regulatory requirements to avoid penalties.
7. Document findings and create an action plan
A DIY audit is only worthwhile if you can later improve your business finances, operations, and compliance. To do so, you should first compile all the information gathered during the previous steps into a comprehensive report. This report should detail the financial health of the business, highlight any discrepancies or areas of concern, and note potential opportunities for improvement.
Based on these findings, develop an action plan with goals to address each issue. Assign responsibilities to team members for implementing changes and set realistic deadlines. The objectives should include a clear timeline for follow-up reviews. This step is crucial for turning the audit from a theoretical exercise into practical business improvements.
When should you call an accountant for a business audit?
DIY audits are a great way to save money, but not every business can perform one. There are several scenarios when you may benefit from professional help.
Managing complex financial structures
If your business has a complex financial structure, then hiring an accountant is essential. This could include situations with multiple income streams or overseas transactions.
For example, suppose you are running a multinational corporation (even a small one) with subsidiaries in different countries. In that case, you’ll need an accountant to manage intercompany transactions, consolidate financial statements, and ensure compliance with diverse accounting standards.
Preparing for the tax season or government audits
Your business may benefit from an accountant’s expertise if you are preparing documents for tax lodgement or an ATO audit. This process can be tedious and time-consuming, and an accountant can take a lot of the work off your hands.
For example, if you are facing a government audit, an accountant can review financial documents, identify potential discrepancies, and guide how to address any issues before the audit.
Additionally, tax experts will be able to pinpoint any missed opportunities when it comes to claiming tax benefits and allowances, saving your money.
Growing your business
As your business grows, you’ll be seeing more financial transactions. As a result, managing complexity and scale may become more challenging. An accountant can help streamline financial processes, implement efficient accounting systems, and provide insights into financial performance.
For instance, a rapidly expanding retail business might need an accountant to manage cash flow, optimise inventory levels, and ensure timely payments to suppliers. They can do this, all while maintaining compliance with financial regulations.
Needing expert financial analysis and advice
If your business is undergoing strategic financial planning and optimisation, hiring an accountant is advisable. Accountants can analyse financial data to identify areas for improvement, provide expert advice on financial structuring, and help develop long-term financial strategies.
Ensuring legal compliance and risk mitigation
Finally, accountants can review your business’s financial practices to ensure they comply with Australian laws and regulations. This reduces the risk of penalties and legal issues.
For instance, an accountant can help your business implement robust internal control procedures to prevent errors in financial reporting.

How an accountant makes a business audit easier

Accountants deeply understand tax laws, compliance requirements, and financial structuring. They conduct accurate and efficient audits, preventing errors and non-compliance.
Delivers strategic financial advice
Beyond conducting audits, accountants provide valuable strategic financial advice. They can help your businesses develop long-term financial plans, identify opportunities for growth, and optimise financial performance.
Reduces risks
Finally, accountants help minimise risks by ensuring accurate reporting, avoiding penalties, and reducing errors. This protects your business from legal and financial repercussions and enhances its reputation.
FAQ
What is the difference between a financial audit and a tax audit?
A financial audit examines the accuracy of financial statements, while a tax audit verifies the correctness of tax returns and payments.
How often should a small business conduct an audit?
The frequency depends on the business’s size and complexity, but annual audits are common for ensuring compliance and financial health.
What happens if I make an error in my business audit?
Errors can lead to penalties, missed deductions, and inaccurate financial reporting. Hiring an accountant can mitigate these risks.
How much does a professional business audit cost?
The cost varies based on the business’s size, complexity, and the accountant’s fees. Generally, it requires professional fees when compared with DIY but offers greater assurance and expertise.
Business audits and compliance
If your business has a simple financial structure, then it’s likely just fine to run a DIY audit. It’s a good idea to implement it as a regular practice at least once per year.
However, suppose your business is complex, works internationally, is facing an ATO audit, or you run into complicated questions during your DIY audit. In that case, it might be time to turn to a professional. Annual financial audits are compulsory for large proprietary companies and foreign-controlled small proprietary companies who have not applied for exemption.
At the end of the day, your main goal is to ensure compliance across business, industry, and tax laws and regulations, as well as your business’s financial health.
