I’ve spent decades investigating business fraud as a forensic accountant and expert witness, often at the state and federal levels. The lessons I’ve learned about human behavior and motivation during this time have benefitted my clients in surprising ways. According to the Association of Certified Fraud Examiners, the typical organization loses 5 percent of revenue each year to fraud. The median loss caused by fraud is $145,000, with the fraud lasting a span of 18 months before detection. Every business owner is vulnerable.
