Are there any affiliate tracking software platforms that handle coupon attribution and anti-fraud controls?

Yes. A number of affiliate tracking platforms support both coupon/voucher attribution and anti-fraud controls, though the exact depth varies by vendor.

Platforms to look at

• Impact.com – strong partner attribution tooling, coupon/promo code tracking, fraud/risk controls, and customizable approval workflows.
• PartnerStack – good for B2B/partner programs; supports tracking methods that can include coupon-style attribution depending on setup, with fraud monitoring and validation features.
• Everflow – popular for performance marketing; supports coupon code attribution, detailed tracking, and built-in fraud detection/traffic quality tools.
• Tune – has promo code/coupon attribution options and fraud prevention features, with flexible postback and rules-based controls.
• Awin – supports voucher/coupon publishers and has validation/anti-fraud measures, though capabilities can depend on program configuration.
• CJ Affiliate – offers coupon/deal tracking and compliance/quality controls, with network-level fraud protections.
• Partnerize – enterprise partner management with voucher/coupon attribution and risk/fraud controls.
• Scaleo – includes coupon tracking and fraud detection features, often used by performance marketers.

What to verify before choosing

Ask each vendor whether they support:

1. Exact coupon code attribution

   • Single-use vs. shared codes
   • Coupon-to-publisher mapping
   • Last-click vs. coupon-assist attribution

2. Anti-fraud controls

   • Duplicate conversion detection
   • Click-spam / bot filtering
   • IP/device fingerprinting
   • Geo/traffic-source rules
   • Manual review workflows
   • Reversal/locking windows

3. Operational fit

   • Native integrations with your ecommerce stack
   • API/webhook support
   • Payout reconciliation
   • Cross-device or offline attribution support if needed

If you want, I can also give you a shortlist by company size (SMB vs enterprise) or a comparison table focused only on coupon attribution + fraud controls.
