How to Prevent Fraud When Selling Digital Products

The Fraud Problem

Digital product sellers face unique fraud challenges. Unlike physical goods, digital products are delivered instantly — meaning a fraudster gets the product before a chargeback is even filed. Common fraud types include:

• Stolen credit cards — Fraudsters use stolen card details to purchase products
• Chargeback abuse — Customers claim they never received the product after downloading it
• Account sharing — Customers share serial codes or download links
• Bulk fraud — Bots making hundreds of purchases with stolen cards

Built-in Fraud Protection on Sellup

Sellup includes multiple layers of fraud protection at no extra cost:

Email & IP Blacklists

Block known fraudulent email addresses and IP ranges. When a blacklisted customer tries to check out, the order is automatically blocked.

CAPTCHA Integration

Add CAPTCHA challenges to your checkout to prevent bot purchases.

Rate Limiting

Automatic rate limiting prevents rapid-fire purchase attempts from a single IP address.

Webhook Signature Verification

All payment webhooks (PayPal, Stripe, Binance, etc.) are verified with cryptographic signatures to prevent spoofed payment notifications.

Account Lockout

After multiple failed login attempts, accounts are temporarily locked to prevent brute-force attacks.

2FA Security

Merchants can enable two-factor authentication to protect their dashboard from unauthorized access.

Additional Tips

• Use crypto payments — Crypto transactions cannot be charged back
• Monitor your orders — Check for patterns like multiple orders from the same email
• Set stock limits — Prevent bulk purchases by limiting quantities per customer
