Online fraud is not a rare event. For eCommerce merchants, it is a recurring operational challenge – one that costs the global industry tens of billions of dollars annually, and one that most small and mid-size merchants are underprepared for.

The good news: most fraudulent orders share recognizable patterns. With the right systems in place, the majority can be stopped before they ship. This guide covers the practical fraud prevention strategies that work for online stores, whether you are running a Shopify boutique, a WooCommerce catalog, or a high-volume Adobe Commerce operation.

Not all eCommerce fraud is the same. Before you build a prevention strategy, it helps to know what you are up against:

Card-Not-Present (CNP) Fraud

Someone uses stolen credit card information to place an order on your store. The legitimate cardholder later disputes the charge, and you are left without the product or the payment.

Friendly Fraud

A real customer makes a real purchase, receives the product, and then disputes the charge with their bank – claiming it was unauthorized or that the item never arrived. This is one of the most prevalent and fastest-growing fraud types for eCommerce merchants.

Refund Abuse

Customers exploit your return or refund policy – claiming items were defective, not received, or returning an empty box.

Account Takeover (ATO)

A customer’s account is hacked and used to place fraudulent orders, often to addresses the legitimate customer has never used.

1. Use a Dedicated Fraud Protection Platform

Manual order review does not scale, and it still misses sophisticated fraud. A dedicated fraud protection platform like Evereye analyzes every transaction at the moment of placement – before fulfillment – using behavioral data, device signals, and order pattern analysis. Evereye delivers clear approve or decline decisions on every order, so your team does not have to guess.

When you use Evereye, you can also remove restrictive gateway settings like aggressive AVS and CVV blocks that reject good customers along with bad ones. Evereye handles the fraud detection, so your checkout can stay open – approving more legitimate orders while still stopping fraud before it ships.

If you are using Evereye, the steps below are handled for you. If you are managing fraud without a dedicated platform, these manual measures can help reduce your exposure:

2. Enable Address Verification (AVS)

AVS checks whether the billing address provided by the customer matches the address on file with their card issuer. A mismatch is a risk signal. Most payment processors offer AVS – make sure it is enabled and that you have a policy for handling mismatches.

3. Require CVV Verification

Always require CVV codes at checkout. Fraudsters using stolen card numbers often do not have the CVV, and requiring it filters out a meaningful share of CNP fraud attempts.

4. Monitor for Velocity Patterns

Multiple orders from the same IP address, device, or email domain in a short period can indicate card testing or coordinated fraud. Set up velocity rules or use a tool that identifies these patterns automatically.

5. Review High-Risk Orders Before Shipping

Not every suspicious order needs to be cancelled. Build a review workflow for high-risk transactions – orders with billing/shipping address mismatches, unusually large order values, or expedited shipping to an unverified address. A quick manual review can save a costly mistake.

6. Document Everything for Chargeback Defense

For every order you fulfill, document the transaction: IP address, device, order notes, confirmation email, delivery tracking. If a customer disputes a legitimate purchase, this documentation is your best defense in the chargeback process.

7. Have a Chargeback Management Strategy

Even with strong fraud detection, some chargebacks will happen. When they do, you need a system in place to manage disputes effectively. Evereye’s chargeback management service handles the dispute process for you – managing evidence, responses, and resolution so your team can focus on running the business instead of fighting chargebacks.

Shopify

Shopify includes a basic fraud analysis tool, but it has limitations in accuracy and scope. For higher-volume stores or those in high-risk categories – electronics, luxury goods, apparel – Evereye Shopify fraud protection adds a more comprehensive layer of detection integrated directly into your order flow.

WooCommerce

WooCommerce does not include native fraud detection. This makes a dedicated fraud protection integration a practical necessity for any store processing significant transaction volume.

Adobe Commerce / Magento

Enterprise merchants on Adobe Commerce often face higher-value fraud attempts. Evereye’s Adobe Commerce integration is designed for this environment – delivering real-time approve or decline decisions on high-value transactions without adding checkout friction.

Even with the best prevention tools, some fraud will get through. When it does:

• File the chargeback dispute with all documentation
• Block the fraud signals (email, device, IP, shipping address) going forward
• Report confirmed fraud to your payment processor
• Review your detection settings to see if a rule change would have caught it

Every fraudulent order is data. Use it to tighten your defenses.

Fraud prevention is not a one-time setup. It is an ongoing operational practice – part technical tool, part process, part awareness. The merchants who manage fraud most effectively combine automated detection for scale, smart review workflows for precision, and continuous improvement for adaptation. Evereye brings all three together in one platform.
