eCommerce Fraud Prevention Solutions

Protect eCommerce Businesses from Fraud

Modern ecommerce fraud extends far beyond stolen credit cards. Fraudsters target every stage of the customer journey, from creating fake accounts and abusing promotional offers to taking over customer accounts, testing stolen payment methods, exploiting loyalty programs, and filing fraudulent chargebacks after an order has been fulfilled.

IPQS helps merchants identify high-risk customers before fraud impacts revenue. By combining device fingerprinting, IP reputation, email verification, phone validation, proxy detection, and behavioral risk analysis, merchants can make more informed decisions throughout the customer lifecycle while minimizing friction for legitimate shoppers.

Whether you're operating a Shopify storefront, an enterprise marketplace, a subscription business, or a global ecommerce platform, IPQS provides real-time fraud intelligence to help protect revenue without sacrificing the customer experience.

Prevent Multi-Accounting & Promotional Abuse

Promotions are designed to acquire new customers, reward loyal shoppers, and encourage repeat purchases. Unfortunately, they are also one of the most common targets for fraud. Criminals frequently create multiple customer accounts to repeatedly claim first-time customer discounts, referral rewards, welcome offers, cashback incentives, and other promotional campaigns.

These fraud rings often use different email addresses, phone numbers, payment methods, and IP addresses to appear as unique customers. Evaluating individual data points alone rarely reveals the full picture. IPQS correlates identity, device, network, and behavioral signals to uncover relationships between accounts that would otherwise appear unrelated.

Identify Duplicate Accounts Before Promotions Are Redeemed

Device Fingerprinting enables merchants to recognize returning devices even when fraudsters change browsers, clear cookies, rotate IP addresses, or create new customer profiles. Combined with IP reputation, email verification, phone validation, and proxy detection, merchants gain a much more complete understanding of customer identity before promotional offers are applied.

IPQS helps merchants identify:

• Duplicate customer accounts
• Coupon and promotional abuse
• Referral and affiliate fraud
• Free trial and introductory offer abuse
• Account farming operations
• High-risk registrations
• Linked customer identities

Stop Account Takeovers Before They Happen

Customer accounts often contain saved payment methods, shipping addresses, purchase histories, gift cards, loyalty rewards, and other valuable information. These accounts have become attractive targets for credential stuffing, phishing campaigns, password reuse attacks, and other forms of account takeover fraud.

Attackers frequently attempt thousands of automated login attempts using credentials obtained from previous data breaches. Once access is gained, they may change account information, place fraudulent orders, redeem loyalty points, or steal stored payment methods before the legitimate customer notices suspicious activity.

IPQS helps merchants identify suspicious login attempts by evaluating device intelligence, IP reputation, proxy usage, behavioral signals, and identity data in real time. Rather than relying solely on passwords, merchants can evaluate the overall risk associated with every authentication attempt.

Detect Suspicious Login Activity in Real Time

Account takeover attempts often generate subtle warning signs long before fraud occurs. A login from an unfamiliar device, an anonymized connection, unusual purchasing behavior, or a sudden change in customer activity may indicate that additional verification is appropriate.

Merchants can use IPQS to:

• Detect credential stuffing attacks
• Identify compromised customer accounts
• Recognize unfamiliar or previously abusive devices
• Detect VPNs, proxies, and anonymized connections
• Apply additional verification to high-risk logins
• Protect customer accounts and stored payment methods

Prevent Loyalty Point & Rewards Abuse

Loyalty programs encourage repeat purchases, but they also create new opportunities for fraud. Criminals may compromise customer accounts to redeem rewards, create multiple accounts to accumulate promotional credits, or exploit referral programs for financial gain. As loyalty programs become more valuable, they increasingly attract organized fraud rings.

Because rewards often have real monetary value, loyalty fraud can result in direct financial losses while eroding customer trust. Recovering stolen points or gift cards is difficult once they have been redeemed, making early detection essential.

Protect Rewards Programs from Fraud

IPQS helps merchants identify suspicious activity before loyalty points, gift cards, store credits, or promotional rewards are redeemed. Device intelligence and identity analysis help uncover repeat offenders, linked accounts, and unusual redemption behavior that may indicate organized abuse.

Merchants can reduce:

• Loyalty account takeovers
• Fraudulent reward redemptions
• Gift card abuse
• Referral program exploitation
• Reward farming and account creation schemes
• Repeat promotional abuse

Detect Payment Fraud Before Orders Ship

Payment fraud remains one of the largest sources of financial loss for ecommerce merchants. Fraudsters use stolen payment credentials, compromised customer accounts, synthetic identities, and automated tools to place fraudulent orders before disappearing long before a chargeback is received.

Waiting until after payment authorization to evaluate risk often leaves merchants with limited options. Real-time fraud screening helps identify suspicious orders before products are shipped, digital goods are delivered, or services are fulfilled.

IPQS evaluates transactions using device intelligence, IP reputation, identity verification, proxy detection, behavioral analysis, and network intelligence to provide a comprehensive fraud assessment before an order is approved.

Evaluate Every Transaction with Real-Time Risk Intelligence

No single fraud signal tells the complete story. A transaction that appears legitimate may still originate from a device associated with previous fraud, a residential proxy network, or a customer identity connected to multiple abusive accounts.

IPQS helps merchants evaluate:

• Card-not-present fraud
• Stolen payment methods
• Synthetic identities
• High-risk customer accounts
• Card testing attacks
• High-value purchases
• Suspicious checkout behavior

Reduce Friendly Fraud & Chargebacks

Not every chargeback is the result of stolen payment information. Friendly fraud occurs when legitimate customers dispute valid purchases, claim they never authorized a transaction, report an item as not received, or request refunds after receiving the product or service. Whether intentional or accidental, these disputes increase costs, consume operational resources, and can negatively impact merchant accounts.

While chargebacks occur after a transaction has been completed, many cases of friendly fraud share warning signs that appear much earlier in the customer journey. Identifying repeat offenders, linked customer accounts, suspicious purchasing behavior, and high-risk identities helps merchants make more informed fulfillment decisions before losses occur.

Identify Customers with Elevated Fraud Risk

IPQS correlates identity, device, and behavioral signals to uncover relationships between transactions that traditional payment screening may miss. Merchants can recognize repeat chargeback behavior, identify customers creating multiple accounts, and detect suspicious activity before products are shipped.

IPQS helps merchants reduce:

• Friendly fraud and chargebacks
• Refund abuse
• "Item not received" disputes
• Digital goods fraud
• Subscription and recurring billing disputes
• Repeat offender activity
• High-risk customer purchases

Verify Customer Identity Before Checkout

Effective fraud prevention begins long before payment is authorized. Every customer interaction provides valuable identity signals that can help merchants distinguish legitimate shoppers from fraudulent users. Verifying customer identity during account creation, login, and checkout reduces fraud while minimizing unnecessary friction for trusted customers.

IPQS combines Email Verification, Phone Validation, Device Fingerprinting, Proxy Detection, and IP Reputation to build a comprehensive identity profile for every customer. Instead of relying on a single data point, merchants can evaluate multiple fraud signals before approving registrations, logins, or purchases.

Build Trust Without Increasing Customer Friction

Every additional verification step introduces the risk of cart abandonment. IPQS enables risk-based decisioning by helping merchants distinguish trusted customers from high-risk users in real time. Legitimate shoppers can move through registration and checkout with minimal interruption, while suspicious activity can be challenged, reviewed, or blocked according to your fraud policies.

Merchants can identify:

• Disposable and temporary email addresses
• High-risk phone numbers
• VPNs, proxies, and anonymized connections
• Previously abusive devices
• Synthetic and suspicious identities
• Automated account registrations
• Linked customer accounts

One Platform. Every Fraud Signal.

Modern ecommerce fraud rarely relies on a single tactic. Fraudsters use multiple identities, devices, payment methods, and accounts to bypass traditional fraud controls, making isolated fraud signals increasingly ineffective. IPQS unifies device intelligence, IP reputation, email verification, phone validation, proxy detection, bot detection, and behavioral analysis into a single fraud prevention platform that provides a complete view of customer risk.

Rather than integrating multiple point solutions, merchants can use IPQS APIs to evaluate customers in real time across account creation, authentication, checkout, payment authorization, and post-purchase workflows. This unified approach helps identify sophisticated fraud earlier, reduce manual reviews, and minimize unnecessary friction for legitimate shoppers.
