As an online business owner, you face many challenges daily. One of the biggest threats to your success is payment fraud. When fraudsters target your business, they can steal products, drain your accounts, and damage your reputation.

Let’s explore the most common types of payment fraud and how you can protect your business.

Types of Payment Processing Fraud You Need to Know

There are multiple types of payment fraud models, which means multiple ways you can be targeted by fraudsters. Here are the most common (and preventable).

Credit Card Fraud

Credit card fraud happens when someone uses stolen card information to make purchases from your store. The real cardholder never approved these transactions. When they discover the fraud, they’ll dispute the charges, leaving you with lost merchandise and chargeback fees.

Identity Theft

Identity theft occurs when criminals steal personal and financial information to make unauthorized purchases. They might get this information through:

• Dumpster diving for discarded documents
• Stealing mail
• Hacking databases with customer information
• Phishing scams that trick people into sharing details

Chargeback Fraud

Also called “friendly fraud,” this happens when a legitimate customer buys something from you, receives the product, but then claims to their bank that:

• They never received the item
• They didn’t authorize the purchase
• The item wasn’t as described

The bank refunds their money while you lose both the product and the payment.

Account Takeover

This fraud happens when someone gains access to your customer’s account on your website. Once inside, they can:

• Make purchases using saved payment methods
• Change shipping addresses
• Steal sensitive customer data
• Access loyalty points or store credit

Triangulation Fraud

This complex scheme involves three parties: the fraudster, an innocent buyer, and your store. Here’s how it works:

1. A fraudster creates a fake store selling items at very low prices
2. A customer buys from this fake store
3. The fraudster uses stolen credit cards to buy the same item from your legitimate store
4. Your store ships the product to the customer
5. Later, the real cardholder disputes the charge

Phishing

Fraudsters send fake emails or create fake websites that look like trusted companies. They trick people into sharing their payment information, which they then use to make fraudulent purchases.

PREVENT FRAUD AT CHECKOUT

How to Protect Your Business from Payment Fraud

Protecting your online store doesn’t need to be complicated. Let’s look at some practical ways to keep fraudsters away from your business.

Use Strong Payment Gateway Settings

Your payment gateway comes packed with powerful tools that stop fraud before it happens:

• Limit payment retries to just 2 attempts to prevent card testing
• Block transactions from high-risk regions where you don’t normally sell
• Require CVV codes for all transactions
• Enable address verification services (AVS) to match billing addresses

There are even more settings you can fiddle with. The more granular you get, the better you’ll be able to prevent fraud at checkout. But don’t enable anything without testing it first!

Implement Strong Authentication

Creating barriers makes it harder for fraudsters to succeed. Here’s how:

Authentication serves as your digital bouncer, making sure only the right people get in. Use these methods to strengthen your security:

• Require strong passwords for all customer accounts
• Set up multi-factor authentication (MFA) for account access
• Implement 3D Secure for transactions (you’ve seen this when your bank sends a code to your phone)
• Apply extra verification steps for suspicious activities

Monitor Transactions Closely

Keep your eyes open for unusual patterns. Fraudsters often leave clues:

Watch for red flags like:

• Multiple orders from the same IP address but different cards
• Mismatched billing and shipping addresses
• Unusually large orders or multiple orders in a short time
• Orders shipping to freight forwarders or high-risk locations

Many payment processors offer AI-powered systems that learn normal patterns and spot suspicious activity automatically.

Adopt Advanced Technology

Modern problems require modern solutions. Today’s technology offers powerful ways to fight fraud:

• Use tokenization to protect payment data
• Implement AI and machine learning for fraud detection
• Partner with reliable third-party payment processors
• Keep your fraud prevention software updated

The best protection combines all these approaches. Start with the easiest steps, then build a more comprehensive strategy over time. You don’t need to implement everything at once. Even small improvements make a big difference in keeping your business safe.

BOOST YOUR APPROVAL RATE

Implementing Fraud Alerts

Fraud alerts serve as your early warning system against payment fraud. They notify you when suspicious activity happens on your site, giving you the chance to investigate before processing potentially fraudulent orders.

Let’s explore how to make fraud alerts work effectively for your business.

What Are Fraud Alerts

Fraud alerts are automated notifications that trigger when transactions meet certain risk criteria.

These alerts flag potentially suspicious activities based on rules you set up in your payment system. When a transaction looks unusual—like an order from a new location, an unusually large purchase, or multiple failed payment attempts—the system sends you an immediate notification.

This gives you enough time to review the order before shipping products or providing services to potential fraudsters.

How to Set Up Alerts

Setting up effective fraud alerts takes just a few steps:

1. Access your payment gateway’s fraud settings section
2. Enable email or SMS notifications for suspicious transactions
3. Set alert thresholds based on your risk tolerance (transaction amount, location, etc.)
4. Configure who receives these alerts (owner, manager, security team)
5. Test your system by simulating suspicious transactions
6. Adjust sensitivity levels based on your false positive rate

Most payment processors offer customizable alert settings. Take time to configure these based on your specific business needs and risk profile.

What to Do When You Get an Alert

When a fraud alert lands in your inbox, here’s what to do.

First, pause the order processing temporarily while you investigate. Review the transaction details carefully, looking for inconsistencies or red flags. Check if the customer has ordered from you before and whether their previous transactions were legitimate. Examine the shipping address, email domain, IP location, and payment details for anything unusual.

Sometimes, a simple verification call or email to the customer can clear things up. Many legitimate customers will appreciate your attention to security. Ask them to confirm details only the real cardholder would know. Avoid requesting sensitive information like full card numbers or passwords.

After investigation, make an informed decision:

• process the order if everything checks out,
• request additional verification if you’re unsure,
• or cancel the transaction if fraud seems likely.

Document your findings for future reference—this helps you refine your fraud detection system over time.

Building Your Alert Strategy

Effective fraud alerts require ongoing refinement. As you gain experience with your system, you’ll learn which alerts matter most for your business. Some merchants find that shipping address changes trigger many false positives, while others discover that time-of-day patterns reveal genuine fraud attempts.

Create a clear standard operating procedure document for handling alerts so your team responds consistently. Include escalation procedures for complex cases and set response time goals—the faster you address potential fraud, the better your chances of preventing losses.

Remember that seasonal changes in shopping patterns might require temporary adjustments to your alert thresholds. During holiday shopping seasons, for instance, you might see more first-time customers and larger order values, which could trigger unnecessary alerts if your settings are too strict.

The goal isn’t to eliminate all alerts—that would leave you vulnerable. Instead, aim for a manageable number of meaningful alerts that help you catch actual fraud without overwhelming your team or frustrating legitimate customers.
