• Segregation of duties remains the single most effective fraud control, and your role as an external accountant or bookkeeper positions you as a natural independent check on client finances.
• Cyber fraud, including phishing, business email compromise, and invoice redirection, is a growing threat that your clients need proactive guidance to address.
• Cloud accounting tools like Xero give you real-time visibility into client transactions, audit trails, and user activity, helping you spot irregularities before they escalate.

Why fraud prevention matters for your practice

Fraud risk is one area where your clients consistently underestimate their exposure. The ACFE's 2024 Occupational Fraud Report confirms that organisations with fewer than 100 employees experience the highest fraud rate of any size category. Median losses for small businesses reached $141,000, a 24% increase from the 2022 report.

These numbers represent a real opportunity for your practice. Clients expect you to spot problems, but proactive fraud prevention advice positions you as a trusted strategic adviser rather than someone who only reports on what's already happened.

Offering fraud advisory services also creates a natural extension of your existing compliance work. You already understand your clients' financial data, transaction patterns, and internal processes. Turning that knowledge into a structured fraud prevention service adds genuine value and strengthens client retention.

Common types of fraud affecting small businesses

Understanding the fraud landscape helps you tailor your advisory approach to each client's risk profile. The ACFE categorises occupational fraud into 3 main types.

• Asset misappropriation: the most common category, accounting for 86% of cases. This includes stealing cash, claiming fictitious expenses, skimming receipts, and taking inventory.
• Corruption: schemes involving bribery, conflicts of interest, and kickbacks from suppliers or vendors.
• Financial statement fraud: the least common but most costly, with a median loss of $766,000. This involves intentionally misstating financial records to hide losses or inflate revenue.

Cyber fraud is an increasingly significant threat for South African small businesses. Phishing attacks trick employees into revealing login credentials or authorising payments. Business email compromise (BEC) scams impersonate senior staff or suppliers to redirect funds. Invoice redirection fraud involves altering banking details on legitimate invoices.

In South Africa, the Southern African Fraud Prevention Service (SAFPS) tracks identity fraud trends and offers a protective registration service. Recommending SAFPS registration is a practical step you can include in your client advisory.

Recognise the warning signs of fraud

As a practitioner with regular access to your clients' financial data, you're well placed to spot red flags early. Knowing what to look for turns routine review work into a fraud detection opportunity.

Watch for these behavioural and transactional warning signs:

• An employee living beyond their apparent means or showing sudden lifestyle changes.
• Reluctance to share duties, take leave, or allow others access to financial records.
• Missing or altered source documents such as invoices, receipts, or purchase orders.
• Unusual transaction patterns, including round-number payments, duplicate entries, or payments to unfamiliar vendors.
• Unexplained adjustments to accounts or frequent overrides of approval processes.

Cloud accounting platforms like Xero make it easier to surface suspicious activity. Audit trails log every transaction edit, user login, and approval action, giving you a clear record to review during client check-ins.

Implement segregation of duties

Segregation of duties is consistently ranked as the most effective anti-fraud control. The principle is straightforward: no single person should control all stages of a financial transaction, from initiation through to recording and reconciliation.

Advise your clients to separate these core functions wherever possible:

• Ordering goods or services from approving and paying invoices.
• Receiving payments from recording and depositing them.
• Managing petty cash from reconciling bank statements.
• Processing payroll from approving payroll changes.

For micro-businesses with only 1 or 2 employees, full segregation isn't always practical. In these cases, your role as an external accountant or bookkeeper becomes even more valuable. You can serve as the independent check by reviewing bank reconciliations, approving batch payments, or conducting periodic spot checks on transaction records.

Strengthen internal controls and processes

Effective internal controls don't need to be complex to be effective. The goal is to build layers of oversight that make fraud harder to commit and easier to detect.

Recommend these controls to your clients based on their business size and risk profile:

• Restrict access to financial systems so each employee only sees what's relevant to their role.
• Require multi-person sign-off for payments above a set threshold, expense claims, and payroll changes.
• Establish clear approval workflows for new suppliers, banking detail changes, and credit notes.
• Review audit trails regularly to track who made changes and when.

Xero's user permissions let you set role-based access for each team member, so clients can limit who views, edits, or approves financial data. Activity logs capture every action taken in the platform, giving you a clear trail to review.

Conduct thorough employee vetting

Hiring practices are a first line of defence against fraud, particularly for roles that involve handling cash, processing payments, or accessing financial systems.

Encourage your clients to build these checks into their recruitment process:

• Verify references from previous employers, with specific questions about the candidate's responsibilities and trustworthiness.
• Conduct background checks, including criminal record and credit checks where legally permissible.
• Confirm qualifications and professional memberships.

Ongoing monitoring matters just as much as pre-hire screening. Mandatory leave policies are a proven fraud detection tool; many schemes unravel when the perpetrator isn't available to maintain them. Regular rotation of duties also reduces the chance of long-running fraud going unnoticed.

Monitor bank accounts and reconcile regularly

Bank reconciliation is one of the most straightforward ways to catch fraud early. Discrepancies between bank records and accounting entries often point to unauthorised transactions, duplicate payments, or manipulated records.

Advise your clients to reconcile their accounts at least weekly, and daily if transaction volumes are high. With Xero's automatic bank feeds, transactions flow directly into the platform in near real time, removing the delays and manual errors associated with statement uploads.

When reviewing client reconciliations, pay particular attention to:

• Payments to unfamiliar or newly added suppliers.
• Changes to existing supplier banking details.
• Round-number transactions that don't match typical invoice amounts.
• Batch payments released without proper approval.

Protect against cyber fraud

Cyber fraud is one of the fastest-growing threats facing South African small businesses. Your clients may not have dedicated IT resources, which makes your guidance on digital security even more valuable.

Cover these priority areas in your fraud prevention advisory:

• Phishing awareness: train staff to verify email sender addresses, avoid clicking suspicious links, and report unexpected requests for payment or login details.
• Business email compromise: advise clients to verify any payment instruction changes by phone, using a known contact number rather than one provided in the email.
• Invoice redirection: recommend that clients confirm banking detail changes directly with suppliers through an independent channel before processing any payment.
• Multi-factor authentication: encourage clients to enable multi-factor authentication on all financial platforms, email accounts, and cloud services.

In South Africa, the SAFPS offers a protective registration service that flags identity fraud attempts. Recommending this to clients who handle sensitive personal or financial data adds a practical, locally relevant layer of protection.

Build a fraud prevention culture

Technical controls are only part of the picture. Clients also need a workplace culture where fraud is openly discussed, easily reported, and consistently addressed.

Suggest these practical steps to your clients:

• Provide regular fraud awareness training, covering common schemes and how to report concerns.
• Set up an anonymous reporting channel so employees can flag suspicious activity without fear of retaliation.
• Create and communicate a code of ethics that makes expectations clear.
• Discuss fraud prevention openly in team meetings to reinforce that it's everyone's responsibility.

Your role as a trusted external adviser gives you credibility when helping clients establish these practices. Offering a short annual fraud awareness session as part of your advisory services is a low-effort, high-value addition to your practice.

Audit high-risk areas regularly

Routine audits of fraud-prone areas help your clients catch problems before they grow. Focus your review efforts on the areas where fraud is most likely to occur.

Prioritise these high-risk areas in your audit schedule:

• Cash handling and petty cash management.
• Refunds, credit notes, and product returns.
• Inventory counts and stock management.
• Payroll processing and employee expense claims.

Random, unscheduled audits are more effective than predictable ones. Let your clients know that audits will happen, but keep the timing and focus areas variable. This makes it harder for anyone committing fraud to prepare or cover their tracks.

The ACFE provides free fraud resources and statistics that can help you benchmark your clients' controls against industry standards. These are useful reference materials when building or reviewing a fraud prevention programme.
