A Small Business Guide to Fraud Detection and Prevention

As someone who’s guided dozens of NYC small businesses, I’ve seen how fraud can quietly eat away profits. From friendly fraud to card-not-present scams, prevention starts with understanding the threats and implementing practical safeguards.

Common Types of Fraud Small Businesses Face

• Card-Present Fraud: Skimmers on POS machines.
• Card-Not-Present Fraud: Online and phone orders.
• Friendly Fraud: Customers disputing legitimate charges.
• Internal Theft: Employee misappropriation of funds.

Example: A Brooklyn café experienced friendly fraud after a busy weekend. Implementing digital receipts and verification solved most disputes.
