How AI Routing Works

Payment routing isn't just about cost — it's about maximizing approvals while managing risk and speed.

The Challenge

Traditional routing uses static rules:

  • Route to cheapest provider
  • Failover on decline
  • Manual provider selection

This ignores critical signals: issuer geography, card type, transaction history, time of day.

Our Approach

ZenPays routing considers:

  1. Approval Probability - ML models trained on 100M+ transactions
  2. Cost Optimization - Real-time fee comparison
  3. Latency - Provider response times by region
  4. Risk Score - Fraud likelihood assessment

Results

  • +12% approval rate improvement
  • -18% processing cost reduction
  • 40ms average latency
