Spotting Red Flags: Early Warning Signs of Business Fraud

September 25, 2025

Fraud can affect businesses and individuals alike—and it often begins long before anyone notices. Detecting the early warning signs is critical to protecting finances, reputation, and peace of mind. At Number Crunching, Inc., our certified fraud examiners and professional bookkeepers help businesses and families identify risks early and implement safeguards that stop fraud before it grows.

Why Early Detection—and the Right Experts—Matter

Fraud isn’t always dramatic; sometimes it’s as subtle as small bookkeeping discrepancies or unusual employee behavior. The longer fraud goes undetected, the greater the financial loss and the harder it is to recover.


When parties allege fraud, it’s essential to have a competent fraud examiner and bookkeeper—especially when building or rebuilding financial records. Investigations and legal proceedings require precise, defensible documentation. A seasoned professional ensures the evidence stands up to scrutiny and the financials are accurate from day one.

Common Red Flags of Business Fraud

Keep an eye out for these indicators in your daily operations:


1. Unexplained Financial Discrepancies

Mismatched records, missing invoices, or frequent “adjusting entries” can signal intentional manipulation.


2. Employees Who Refuse Oversight

Staff who resist sharing their work, avoid vacations, or insist on handling finances alone may be hiding something.


3. Lifestyle Changes Out of Line with Salary

Sudden purchases of luxury items or unexplained cash flow can point to embezzlement.


4. Frequent Vendor or Customer Complaints

Regular disputes over billing or missing payments might indicate someone is diverting funds.



5. Weak Internal Controls

A lack of segregation of duties—such as one person handling both payments and recordkeeping—creates opportunity for fraud.

Elder Fraud: A Growing Crisis

Fraud doesn’t just target businesses. Older adults are increasingly at risk—especially with scammers using AI to create convincing messages and impersonations.



  • Before COVID-19: Reported elder fraud losses across the U.S. were about $500,000 annually.

  • In 2024: Losses skyrocketed to $4.9 billion nationwide.

  • San Diego County: 1,323 victims lost a total of $98.2 million, and the FBI estimates only 25% of cases are reported.

The best way for seniors to fight back is education: learning to recognize scams and staying alert to new tactics that leverage AI and technology.

How Strong Bookkeeping Prevents Fraud

Accurate bookkeeping isn’t just about balancing the books—it’s a powerful fraud deterrent. Consistent, professional bookkeeping provides:


Clear Audit Trails:

  • Easy-to-follow records make it harder to hide unauthorized transactions.
