Fraud can plague any business --organizations reportlosing 5 percent of their annual revenue to fraud. But small businesses exhibit specific vulnerabilities. For starters, they often lack the resources to sufficiently implement internal checks and balances for their accounting systems.

Finally, despite cultivating a culture of trust inside the business, the likelihood of internal fraud is just as high among long-term employees as with contract workers.
