Signs of Ecommerce Fraud & Platform to Protect Your Stores

Online stores have become a major part of daily life, but with convenience comes risk. Ecommerce fraud can disrupt cash flow, damage reputations, and even threaten business survival. This guide will help you spot the early signs of suspicious activity, understand the types of fraud that target online sellers, and explore effective platform and tool that protect your stores from losses, chargebacks, and malicious actors in this guide.

What is ecommerce fraud?

Ecommerce fraud occurs when criminals exploit online stores, payment systems, or customer interactions to steal money, goods, or sensitive information. Fraud not only disrupts operations but also affects profitability and customer trust. Common consequences for merchants include:

• Lost revenue from fraudulent orders or refunds
• Increased chargeback fees and penalties
• Damage to brand reputation and customer trust
• Operational inefficiencies and higher compliance costs

Common signs of ecommerce fraud

Fraud detection early requires knowing what to look for. Ecommerce merchants should pay attention to patterns in orders, payments, accounts, returns, and customer communication that may indicate fraudulent activity.

Order-based indicators

Certain patterns in incoming orders often reveal potential fraud attempts, and recognizing these early helps merchants take action before financial losses occur. Key warning signs include:

• High-value or bulk orders from newly created accounts, which may indicate fraud testing.
• Multiple cards used for a single shipping address, suggesting possible card testing or collusion.
• Shipments to high-risk regions or countries with a history of ecommerce fraud.

Merchants should flag suspicious orders for extra verification, cross-check shipping addresses against fraud databases, and confirm customer details before fulfillment to minimize chargebacks and revenue loss.

Payment and card anomalies

Payment irregularities are a major red flag for ecommerce payment fraud:

• Card-not-present (CNP) inconsistencies, such as mismatched billing addresses, foreign IP locations, or unusual purchase patterns, often indicate stolen card use.
• Multiple failed payment attempts may suggest that fraudsters are testing card credentials.

Prepaid or virtual cards, repeatedly used, can mask identity and complicate chargeback recovery. Merchants should implement automated payment monitoring, flag unusual card activity, and integrate fraud detection tools like Shoplazza Payments to screen high-risk transactions in real time. Proactive monitoring minimizes losses, prevents unauthorized charges, and reduces costly disputes.

Account and device red flags

Fraudsters exploit new or poorly verified accounts to bypass traditional security checks. Indicators include：

• Newly created accounts with incomplete profiles or missing verification information.
• Access from multiple devices, suspicious IP addresses, or VPNs can signal attempts to hide location or evade detection.

Rapid password resets or sudden changes to account information often accompany account takeover (ATO) attacks. Merchants should implement multi-factor authentication, IP and device tracking, and monitor login behavior continuously. Combining account intelligence with behavioral analytics enables early detection of suspicious activity, protecting both merchant revenue and legitimate customers from compromised accounts.

Refund and return patterns

Irregular returns and refunds can highlight both friendly fraud and organized merchant schemes：

• Multiple returns immediately following purchase, particularly of high-value items, indicate potential abuse.
• Discrepancies between original payment methods and refund accounts can reveal attempts to manipulate funds.

Fraudsters may exploit lenient return policies, causing financial and operational strain. Merchants should monitor return velocity, flag repetitive offenders, and verify refund accounts before processing. Policies should balance customer satisfaction with security, including partial refunds or manual review for high-risk items. Proactive management of refund and return behavior prevents revenue loss and strengthens fraud defenses.

Customer communication signals

Customer communication patterns can provide critical fraud clues. Fraudulent buyers often use:

• Disposable emails
• Generic phone numbers
• Fake contact details

which hinder verification and dispute resolution. Aggressive behavior, such as:

• Urgent demands for expedited shipping
• Immediate refunds
• Special handling requests

often accompanies attempts to manipulate merchant processes. Observing the tone, frequency, and legitimacy of communications allows merchants to assess risk before fulfillment. Integrating communication signals with order, payment, and account monitoring enhances detection accuracy. Early intervention based on suspicious messaging can prevent financial losses, reduce disputes, and ensure that legitimate buyers continue to receive a seamless shopping experience.

How to prevent ecommerce fraud? Best practices you should notice

Preventing ecommerce fraud requires a proactive approach that combines technology, process controls, and employee awareness to reduce risk while maintaining smooth customer experiences for legitimate buyers. Key best practices include:

• Implement robust authentication and multi-factor verification: Use 3D Secure (3DS), biometrics, and email or phone verification to confirm the buyer’s identity. These measures are particularly important for high-value transactions.
• Leverage AI-powered fraud screening: Machine learning models can detect unusual patterns, flagging suspicious transactions in real time and reducing false positives.
• Monitor payment and account behavior: Watch for multiple failed payment attempts, repeated use of virtual or prepaid cards, and logins from unfamiliar IP addresses or VPNs.
• Establish clear chargeback and return policies: Document all rules, set thresholds for refunds, and actively manage disputes to prevent abuse.
• Train staff and educate customers: Teams should be aware of social engineering tactics, phishing attempts, and common scam patterns.
• Use trusted fraud prevention platforms: Tools like Shoplazza Payments and TrustDecision can block up to 90% of fraud orders, reduce false declines, and provide chargeback protection, ensuring your revenue remains stable.

These steps collectively minimize financial loss, improve operational efficiency, and maintain trust with genuine shoppers.

Which ecommerce platform and tool include fraud protection？

The right ecommerce platform and tool are critical for merchants who want to safeguard their stores against payment fraud while maintaining smooth customer experiences. Modern platforms like Shoplazza not only provide core shopping and checkout functionality but also integrate advanced fraud detection tools, helping merchants identify risky transactions, reduce chargebacks, and protect revenue in real time. For example:

• TrustDecision Fraud Prevention is designed to provide comprehensive fraud protection for online merchants. It can block up to 90% of fraudulent orders, which is especially valuable as fraudsters often target stores with weaker security measures. In addition, it reduces false declines by up to 90%, helping merchants retain customers who might otherwise abandon their carts due to mistaken rejections. TrustDecision also provides chargeback protection up to 100%, guaranteeing revenue stability for orders that meet specific conditions. By combining proactive detection with automated safeguards, merchants can focus on growth rather than constantly reacting to fraud incidents.
• Shoplazza Payments, developed by the SaaS platform Shoplazza, leverages Early Fraud Warning (EFW) reports from Visa, Mastercard, and JCB networks to flag potentially fraudulent transactions. These reports operate independently of the formal dispute process, allowing merchants to act before a chargeback occurs. Approximately 80% of EFW alerts escalate into disputes if left unaddressed, so timely review is crucial. Upon receiving an alert, merchants can review order details, confirm customer identity, send transaction confirmations, or delay shipping until the order is verified. For high-risk stores, proactive refunds can prevent disputes from impacting account health.

Together with TrustDecision, Shoplazza Payments offers an integrated solution that combines real-time fraud intelligence with actionable merchant tools, ensuring both security and smooth transaction flow for ecommerce businesses.
