The Challenge

PSP Compliance: Speed vs. Risk

Merchants want to go live fast. Acquirers want to manage chargeback risk. Regulators want every transaction monitored. Manual merchant underwriting and slow transaction screening create the worst of all worlds — slow, expensive, and risky.

⏱️

Merchant Underwriting Bottleneck

Manual KYB review takes 5-10 days per merchant. Merchants churn to faster competitors before you've even approved them.

💳

Real-Time Transaction Risk

Fraud, chargebacks, sanctions breaches — all need to be caught before settlement. Batch screening from last night's activity is too late.

📉

Merchant Churn at Scale

High-risk merchants slip through underwriting; low-risk merchants churn from slow approval. Neither extreme is profitable.

FAQ

Payment Processor FAQ

How fast can merchants be onboarded?+
Low-risk merchants: 10 minutes from application to first transaction. High-risk or high-value merchants: 2-4 hours with structured EDD and manual compliance review. Both flows run on the same platform.
Do you support PSD2 strong customer authentication (SCA)?+
Our platform integrates with SCA providers for PSD2-compliant authentication flows. We don't replace your SCA vendor — we complement it with KYC, AML, and transaction screening.
How do you handle high-risk MCC codes?+
MCC codes drive automatic risk tier assignment. High-risk categories (gambling, adult, nutra, crypto) trigger enhanced underwriting workflows with additional documentation and senior review.
Can we process 100M+ transactions per day?+
Yes. Our infrastructure handles high-volume transaction processing with horizontal scaling. Sub-200ms per-transaction screening is standard across all volume tiers.
Do you support card-not-present fraud detection?+
Yes. ML-based fraud detection covers card testing, velocity anomalies, device-fingerprint inconsistencies, and behavioral red flags. Integrates with your chargeback data for continuous model refinement.
How do you handle chargeback monitoring obligations?+
We track chargeback rates per merchant against Visa/Mastercard thresholds. Merchants approaching chargeback ratio limits are flagged automatically; remediation workflows route to risk management.
