Occupational fraud can impact a manufacturer’s bottom line

Manufacturers face numerous financial and operational risks, but one potentially costly threat can come from within their own organizations. Occupational fraud occurs when employees, managers or executives misuse their positions for personal gain. These schemes can go undetected for months or even years, resulting in substantial financial losses.

The Association of Certified Fraud Examiners (ACFE) highlights the seriousness of this problem in Occupational Fraud 2026: A Report to the Nations. For manufacturers, understanding how fraud occurs and implementing appropriate safeguards are essential to protecting profitability.

The ACFE report in a nutshell

The ACFE report examined 2,402 fraud cases across 143 countries and territories, involving more than $3.4 billion in losses. The median loss was $104,000 per case; however, some businesses suffered considerably greater damage.

Occupational fraud generally falls into three categories: asset misappropriation, corruption and financial statement fraud. According to the ACFE's 2026 report, asset misappropriation was the most prevalent, occurring in 90% of cases. Corruption was involved in 45% of cases, while financial statement fraud occurred in just 6%. However, financial statement fraud was particularly damaging, producing a median loss of $1 million.

Recognize the warning signs

Manufacturers tend to be especially vulnerable to certain schemes because of their complex supply chains, substantial inventory holdings and numerous purchasing transactions. For example, billing fraud may involve an employee creating fictitious vendors, approving inflated invoices or arranging payments for goods that were never delivered. In some cases, purchasing personnel may receive kickbacks from suppliers in exchange for favorable contracts or inflated prices.

Inventory theft is another concern. Dishonest employees may steal raw materials, finished products, equipment or other valuable assets. These losses can be difficult to identify when inventory records are inaccurate or physical counts are infrequent.

Financial statement fraud, though less common, can also create serious problems. Employees or executives may intentionally manipulate inventory valuations, overstate revenue or conceal expenses to make financial performance appear stronger than it actually is.

Strengthen internal controls

A well-designed internal control system can significantly reduce opportunities for occupational fraud. The ACFE's 2026 study found that more than half of the fraud cases involved either inadequate internal controls or management overriding existing safeguards.

One important precaution is segregation of duties. For example, the employee responsible for approving purchases shouldn't also have unrestricted authority to establish vendors, process invoices and authorize payments. Dividing these responsibilities makes it more difficult for one person to carry out and conceal fraudulent transactions. Manufacturers should also consider conducting regular inventory reconciliations, verifying changes to vendor information, and requiring independent reviews of significant purchases and payments.

The ACFE identified several controls associated with substantially lower fraud losses. Organizations with management reviews had median losses 55% lower than those without. Proactive data monitoring and analysis were associated with a 53% reduction, while surprise audits were associated with a 50% reduction.

Encourage employees to speak up

Tips uncovered 43% of the fraud cases examined in the ACFE's 2026 report, making them the most common detection method. More than half of those tips came from employees who often recognize suspicious behavior before management becomes aware of a problem. Manufacturers can encourage reporting by establishing confidential reporting channels, communicating their availability and maintaining policies that prohibit retaliation against individuals who raise concerns in good faith.

The ACFE recommends combining fraud training with a formal reporting mechanism to increase the likelihood that your organization will receive fraud tips. Respondents without a reporting mechanism or formal training program incurred a median loss of $175,000. By comparison, organizations with both controls in place reported a median loss of $85,000. Having both controls also reduced the duration of fraud schemes by 40%.

Take a proactive approach
