Why small businesses face the greatest fraud risk

Fraud hits small businesses harder than most owners expect. As their trusted adviser, you are well placed to raise the issue and help them act before losses mount.

The Association of Certified Fraud Examiners (ACFE) Occupational Fraud 2026: A Report to the Nations found that organisations with fewer than 100 employees had the highest median loss of any organisation size. The median loss for these smaller organisations was US$126,000 per case. Across all organisations, the ACFE estimates that roughly 5% of annual revenue is lost to fraud.

Several factors make small businesses especially vulnerable. Limited staff means fewer checks and balances. Informal processes leave gaps that bad actors can exploit. And close personal relationships can make owners reluctant to question trusted employees.

These dynamics create an opportunity for your practice. By building high-integrity accounting processes into every client engagement, you reduce risk while strengthening your advisory role.

Common types of small business fraud

Understanding the fraud landscape helps you advise clients on where to focus their defences. Fraud broadly falls into two categories: internal (employee-driven) and external (cyber and digital).

Employee fraud

The ACFE identifies three main types of occupational fraud. Asset misappropriation, which includes stealing cash, skimming receipts, and claiming fake expenses, accounts for 90% of cases. Corruption, such as conflicts of interest and bribery, appears in 45% of cases. Financial statement fraud, the least common at 6% of cases, typically causes the largest losses.

For your clients, asset misappropriation is the most likely threat. Employees handling cash, processing payments, or managing inventory have the greatest opportunity.

Cyber and digital fraud

External fraud is rising. Australians reported $2.18 billion in scam losses in 2025, according to the National Anti-Scam Centre's Targeting Scams report, and payment redirection scams caused the second-highest losses of any scam type. The most common digital threats your clients face include:

• Business email compromise (BEC), where scammers impersonate a supplier, executive, or trusted contact to request urgent payments to fraudulent accounts
• Payment redirection scams, where fraudsters intercept genuine invoices and substitute their own bank details before forwarding them to the payer
• Invoice fraud, where fake invoices are sent for goods or services never ordered or delivered
• Phishing, where deceptive emails or messages trick staff into revealing login credentials, financial data, or personal information

When reviewing client processes, consider both internal and external threats. A strong fraud prevention program addresses both.

Red flags that suggest fraud

Spotting fraud early limits the damage. Encourage your clients to watch for behavioural and financial warning signs, and build these checks into your own review processes.

Behavioural warning signs

Certain employee behaviours can signal that something is wrong. Watch for:

• Refusal to share duties or let others handle specific tasks
• Reluctance to take leave or allow anyone else access to their work
• A lifestyle that seems inconsistent with their salary
• Unusually close relationships with suppliers or customers
• Resistance to new controls, audits, or oversight measures

Financial warning signs

Regular reconciliation and review will help you spot financial red flags, including:

• Unexplained adjustments or journal entries
• Missing or altered source documents
• Duplicate payments to the same supplier
• Inventory shortages that can't be explained
• Bank account discrepancies or unusual transaction patterns

None of these signs confirm fraud on their own, but a pattern warrants investigation. Make it part of your regular client review to scan for these indicators.

10 fraud prevention strategies for your clients

These strategies cover the practical steps you can recommend, implement, or oversee for your clients. Each one reduces the opportunity for fraud and strengthens your advisory relationship.

1. Segregate financial duties

One of the most effective fraud deterrents is ensuring no single person controls an entire financial process. At a minimum, the person recording transactions shouldn't be the same person authorising payments or reconciling accounts.

For very small businesses where full segregation isn't practical, suggest that the business owner personally reviews bank statements and approves payments. You can also position your practice as an external check, providing the independent oversight that a small team cannot deliver internally.

2. Implement thorough hiring practices

Encourage clients to verify references, confirm employment history, and conduct background checks for roles involving financial access. This applies to new hires and to existing employees moving into sensitive positions.

Long-serving staff need the same checks as everyone else. The ACFE's 2026 report found that employees with more than 10 years of tenure caused the highest median losses. Mandatory leave policies are another useful tool, as fraud often surfaces when the perpetrator is away from the business.

3. Establish internal controls and approval processes

Formal controls reduce the opportunity for fraud. Recommend that clients put in place:

• Multi-person approval for payments above a set threshold
• Restricted access to financial systems based on role
• Documented processes for expense claims, purchase orders, and payroll changes
• Audit trails that log every financial transaction and system change

Cloud accounting platforms like Xero make it straightforward to set user permissions and review the history of changes to transactions.

4. Monitor bank accounts and reconcile regularly

Regular bank reconciliation is one of the simplest and most effective fraud detection tools. Encourage clients to reconcile accounts at least weekly, not just at month-end.

Key items to watch for include unknown payment recipients, payments to unrecognised accounts, missing or out-of-sequence cheques, and transactions that don't match supporting documents. Automated bank reconciliation with bank feeds makes this process faster and brings discrepancies to light sooner.

5. Conduct surprise audits in high-risk areas

Routine audits are useful, but unannounced spot checks are more effective at deterring and uncovering fraud. Focus on areas with the highest risk: cash handling, refunds, inventory management, and expense claims.

Let employees know that surprise audits will happen, but don't share the schedule. The ACFE offers a fraud prevention check-up tool that can help you assess how well your client's controls are working.

6. Train employees on fraud awareness

Employees are your client's first line of defence, but only if they know what to look for. Training should cover how to identify suspicious activity, the importance of reporting concerns, and the consequences of fraud.

Recommend that clients establish an anonymous reporting channel. Tips remain the most common way fraud is detected, and more than half come from employees, according to the ACFE. A written code of ethics reinforces the message that fraud is taken seriously.

7. Protect payment and credit card information

Payment data security is a practical priority for every business. Advise clients to keep business and personal finances strictly separate, limit the number of people with access to payment methods, and use secure online payment services.

For clients who handle customer payment information, ensure they follow the current Payment Card Industry Data Security Standard (PCI DSS). Storing card details insecurely creates both fraud risk and regulatory exposure.

8. Verify business partners and suppliers

Supplier fraud and payment redirection scams often succeed because verification steps are skipped. Encourage clients to:

• Confirm supplier details independently (not through contact information provided in an email)
• Verify bank account changes by phone using a known number
• Check business registration details through the Australian Securities and Investments Commission (ASIC) or the Australian Business Number (ABN) Lookup tool
• Maintain up-to-date records of supplier contacts and payment details

A brief verification call before processing a large or unusual payment can prevent significant losses.

9. Investigate every discrepancy

Small irregularities can be early signs of larger problems. Advise clients to investigate every discrepancy, no matter how minor. A pattern of small anomalies often points to systematic fraud.

It's tempting to dismiss minor issues when the business is busy, but complacency gives fraud room to grow. Build a culture where staff are expected to question unusual transactions.

10. Use technology to strengthen fraud detection

Technology is a powerful ally in fraud prevention. Cloud accounting software provides real-time visibility into financial data, automated alerts for unusual activity, and detailed audit trails that make it harder to conceal fraud.

Encourage clients to enable multi-factor authentication on all financial systems, restrict user access based on role, and review system activity logs regularly. These features are built into modern platforms and require minimal effort to activate. Xero Partner Hub gives you a central view across your client work, with widgets such as bank feed alerts that help you see which clients need attention.

How Australia's Scams Prevention Framework affects your clients

The Scams Prevention Framework Act 2025, enacted in February 2025, puts more responsibility on the businesses your clients rely on every day. The Government has now designated banking, telecommunications and key digital platforms as the first sectors under the framework. The platforms group covers social media, search engines and instant messaging services.

These sectors have until 31 March 2027 to build systems that prevent, detect and disrupt scams. From then, the banks, telcos and platforms your clients use to bank, communicate and transact online must step up their scam defences. They'll also need to give customers simple ways to report a scam and resolve a complaint.

Accountants and bookkeepers, along with most client businesses, aren't directly designated under the framework. Your clients will still look to you for guidance on scam prevention. Staying across these changes lets you spot gaps in their controls before scammers do.

Start by reviewing each client's fraud prevention measures against the framework's principles. Strong controls show good governance and cut their exposure to scams, even while the formal obligations sit with designated sectors.

FAQs on fraud prevention

Here are answers to frequently asked questions about fraud prevention for small business clients.

How often should clients review their fraud prevention measures?

A formal review at least once a year is a good baseline, but high-risk areas like cash handling and payment processing benefit from quarterly checks. Building this into your regular client engagement keeps it from being overlooked.

What should a client do if they suspect fraud?

The first step is to preserve evidence. Advise clients not to confront the suspected individual or alter any records. They should then secure relevant documents, restrict the suspected person's system access and seek professional advice, which may mean engaging a forensic accountant or reporting to the police.

Are there specific industries more prone to small business fraud?

Businesses that handle large volumes of cash, inventory, or customer payment data tend to face higher fraud risk, with retail and hospitality as typical examples. Fraud can occur in any industry, because opportunity matters more than sector.

How can technology reduce the risk of invoice fraud?

Automated three-way matching (purchase order, goods receipt, and invoice) catches discrepancies before payment. Cloud accounting platforms with bank feeds surface unusual transactions sooner than manual reconciliation, while multi-factor authentication and role-based access controls add protection.

What role does cyber insurance play in fraud prevention?

Cyber insurance can limit the financial impact of fraud, though cover for business email compromise and payment redirection varies between policies. Advise clients to review their cover each year and keep strong controls in place as their main defence.
