Stripe charges 30%. We charge 15%.
Stripe Smart Disputes launches in June 2026. Their fee: 30% per won dispute. CertNode Reflex does the same thing at half the cost, with pre-dispute evidence that Stripe doesn't capture.
Why merchants switch to CertNode
Evidence before the dispute
Most merchants scramble to find evidence after a chargeback hits. By then, 3D Secure results and device data are gone. Vault captures it all at payment time with RFC 3161 timestamps.
Lowest fees in the market
15% success fee on Reflex. Chargeflow charges 25%. Disputifier charges 20%. Stripe Smart Disputes charges 30%. You only pay when we win your dispute.
AI defense narratives
Claude analyzes your evidence and writes dispute-specific narratives with legal language tailored to Visa and Mastercard requirements. Not templates.
Works across 5 platforms
Stripe, Shopify, PayPal, Square, WooCommerce. One defense system across every payment platform you use. Most competitors only work on Stripe.
