Three Payments Fraud Threats Your Small Business Can’t Afford to Ignore

1. Card-Not-Present Fraud: Your Biggest Payment Loss Driver 

Card-not-present (CNP) fraud happens when stolen card data is used to make a payment without the physical card, through your online store, over the phone, or any manually entered transaction. It is by far the dominant form of card fraud in Canada. The Canadian Anti-Fraud Centre tracked over $638 million in total fraud losses in 2024, and, and according to Visa Canada, the majority of credit card fraud losses occur via card‑not‑present (CNP) channels.  

The reason it hits small businesses so hard comes down to a brutal timing problem. By the time a fraudster’s stolen card triggers a chargeback, you have already shipped the product, delivered the service, and processed the payment. You lose the goods, the revenue, and typically pay a chargeback fee on top of it. 

What this looks like in practice: An independent online retailer sees a surge of orders before a holiday. Higher-than-usual order values, requests for expedited shipping, billing and shipping addresses that don’t match. These are classic CNP fraud signals. Without real-time fraud screening, those orders ship before the stolen card data is flagged. The chargebacks arrive weeks later. 

How to protect yourself: 

• Enable Address Verification Service (AVS) and CVV checks on all card-not-present transactions. 
• Use 3D Secure authentication (Verified by Visa, Mastercard Identity Check) for online checkouts. It shifts chargeback liability to the card issuer on successfully authenticated transactions. 
• Flag orders with mismatched billing and shipping addresses, unusual volumes, or rushed delivery requests for manual review. 

2. Payment Redirection and Account Takeover Scams 

This category of fraud does not target your customers. It targets you and your team directly. Fraudsters compromise your business processes through phishing emails, spoofed supplier invoices, and fake payment instruction changes, redirecting funds straight to criminal accounts. By the time you realize what has happened, the money is gone, and unlike a credit card dispute, there is often very little recourse once a wire transfer or e-Transfer has been sent. 

Payments Canada’s 2024 study found impersonator fraud to be the most common type of payment fraud experienced by Canadian businesses, affecting 25% of those victimized. CFIB data reinforces this: email scams and phishing were the top attack vector reported by small business owners, cited by 85% of those who experienced fraud. 

The psychological mechanics of these scams are well-crafted. A fraudster posing as a known supplier sends an invoice that looks nearly identical to the real one, but with updated banking details. A fake message appearing to come from your accountant or a senior manager requests an urgent transfer. Under time pressure, and without a verification step, employees process the payment. 

What this looks like in practice: A construction company receives an email from what appears to be their lumber supplier, same logo, same format, asking them to update the banking details on file before the next payment run. One employee updates the record. The next scheduled payment of $12,000 goes to a fraudster. 

How to protect yourself: 

• Establish a strict verbal confirmation rule: any change to a supplier’s banking information must be confirmed by phone using a number you already have on file, never the one provided in the request. 
• Use multi-factor authentication (MFA) on all business banking, email, and accounting platforms. 
• Train your team to inspect email sender addresses carefully. Spoofed domains often differ from the real one by a single character. 
• Set dual authorization requirements for payments above a defined threshold so no single person can approve a large transfer alone. 

3. Chargebacks and Friendly Fraud: Paying for Transactions You Already Completed 

Not all chargebacks stem from criminal activity. A significant share, industry estimates put this as high as 45%, come from what the payments industry calls “friendly fraud.” A customer disputes a legitimate transaction with their bank rather than contacting you directly. They may have forgotten the purchase, want a return your policy does not cover, or are exploiting the dispute system outright. Either way, the merchant loses the sale and pays the dispute fee. 

CFIB data shows that chargebacks rank among the fraud types most likely to result in actual financial loss, affecting 17% of small businesses who experienced them, and merchants who do contest disputes win only a fraction of the time. For small businesses, this compounds in a specific way: you often lack the staff and documentation systems needed to fight disputes effectively. 

What this looks like in practice: A small spa charges a client for a service. Two weeks later, a chargeback arrives. The client told their bank the charge was unrecognized. The spa has no signed intake form, and no confirmation email showing the client acknowledged the booking. The bank sides with the cardholder. 

How to protect yourself: 

• Build a paper trail for every transaction: confirmation emails, signed receipts, delivery tracking numbers. 
• Display your refund and cancellation policy prominently at checkout, on receipts, and in booking confirmations. 
• Respond to every dispute promptly with documentation. Missing response deadlines means automatic loss. 
• If chargebacks are a recurring issue, ask your payment processor about dispute monitoring alerts so you can respond the moment one is filed. 

The Bottom Line 

Fraud prevention is not just an IT problem. It is a business operations problem. Most of these attacks succeed because of process gaps, not because they are technically unstoppable. Verify payment instruction changes by phone. Enable the authentication tools your payment processor already offers. Document your transactions thoroughly. Show your team what a phishing email actually looks like. 

This Fraud Prevention Month, I would encourage every small business owner to spend 30 minutes auditing just one of these three areas. The fraud landscape is getting more sophisticated, and CFIB data shows that 90% of Canadian business owners are worried that AI will make attacks harder to detect. That concern is reasonable. But the fundamentals of protection have not changed. Strong processes, a skeptical eye, and the right payment tools remain your best defence.
