Fraud remains a significant risk for small and midsize businesses, especially when internal controls, financial oversight, or reporting processes are stretched thin. While financial statement audits are not designed specifically to uncover fraud, they can help identify unusual activity, strengthen accountability, and deter would-be fraudsters. Recent findings from the Association of Certified Fraud Examiners (ACFE) reinforce the important role audits can play as part of a broader fraud prevention strategy.

Recent ACFE study

External audits can serve as an effective antifraud control. The ACFE’s Occupational Fraud 2026: A Report to the Nations analyzed 2,402 occupational fraud cases across 143 countries. Consistent with previous studies, the report estimates that organizations lose approximately 5% of annual revenue to occupational fraud. It also found that a typical fraud scheme lasts 12 months before detection.

More than half of the cases in the 2026 study involved either a lack of internal controls or management overriding existing controls. Organizations with strong antifraud controls, such as external financial statement audits, management review, proactive data monitoring and surprise audits, generally experienced lower fraud losses and detected fraud more quickly than organizations without those safeguards.

Limits on audit assurance

The primary purpose of an audit is not to detect fraud. Instead, an audit provides an opinion about whether the financial statements are fairly presented, in all material respects, in conformity with U.S. Generally Accepted Accounting Principles (GAAP) or another applicable basis of accounting.

An audit provides reasonable assurance that a business’s financial statements are free from material misstatement and conform with GAAP or another applicable reporting framework. However, external audits do not provide a guarantee against intentional financial statement fraud or inadvertent errors.

The role audits play in fraud detection

Auditors play an important role in supporting the integrity of financial reporting. Certain audit procedures may also help reveal suspicious activity and identify weaknesses in your organization’s controls.

Risk assessments. These assessments identify areas with a higher risk of misstatement or error. They help direct the auditors’ attention to the accounts and transactions that may require more rigorous audit procedures. Auditors evaluate the business’s operations, financial reporting processes, internal controls and industry environment to pinpoint potential risks. Then they develop audit plans focused on those areas.

Audit fieldwork. For example, they may test selected financial transactions and account balances to verify accuracy and completeness. They may also examine supporting documentation, such as invoices, contracts and bank statements, to determine whether transactions are legitimate and properly recorded.

Auditors are trained to recognize potential warning signs of fraud, including unusual transactions, inconsistencies in financial records and deviations from standard procedures. When auditors identify red flags, they may ask additional questions and perform further procedures to help determine whether the financial statements are fairly presented and conform to the applicable reporting framework.

Financial reporting compliance. Businesses must comply with a wide range of laws and regulations, including those related to financial reporting, taxes and corporate governance. Auditors consider laws and regulations that could have a material effect on the financial statements and may identify issues that warrant management’s attention or further review.

A stronger defense

No organization is immune to fraud. However, an external audit can help reduce risk by examining financial reporting procedures, evaluating internal controls and identifying potential warning signs before they become larger problems.
