How GuardScore Works

Payment Compliance Scoring Explained

GuardScore is a 0-100 payment compliance risk score that predicts payment processor approval likelihood. Built on enterprise-grade machine learning validated against real merchant outcomes, it analyzes multiple risk dimensions including VAMP exposure, operational health, and our proprietary AI Fraud Exposure layer: giving you the most accurate assessment of your merchant account health available today.

What Affects Your GuardScore?

Five weighted factors combine to create your final score

Chargeback Rate

35% Weight

The #1 factor in your score. Chargebacks divided by total transactions. VAMP threshold is 0.9%: exceed it and your score plummets. Processors use this to predict future risk.

✓ Good: Under 0.5% (80-100 score)
⚠ Okay: 0.5-0.9% (60-79 score)
✗ Bad: Over 0.9% (0-59 score, VAMP penalties)
UNIQUE TO GUARDSCORE

AI Fraud Exposure

20% Weight

Our breakthrough feature. Measures how vulnerable your checkout is to AI-powered fraud attacks: deepfakes, synthetic identities, account takeover bots. We analyze your MFA strength and checkout platform security posture.

What We Analyze: Customer authentication strength, checkout platform security posture, platform architecture risk, AI-powered attack vulnerability

Industry Risk

20% Weight

Your MCC code matters. High-risk industries (CBD, gaming, crypto, nutraceuticals, travel) start with lower baseline scores. Processors have industry-specific thresholds and approval rates.

Low Risk: SaaS, B2B, retail (+20 points)
Medium Risk: E-commerce, subscriptions (neutral)
High Risk: CBD, gaming, forex, adult (-20 points)

Compliance Factors

15% Weight

PCI-DSS compliance, terms of service quality, refund policy clarity, privacy policy, SSL certificates, regulatory licenses. The operational hygiene processors check during underwriting.

Checked: PCI compliance, clear refund policy (30+ days), SSL/HTTPS, ToS, privacy policy, support contact, legitimate business entity

Business Velocity

5% Weight

Processing history length, volume trends, account age. Sudden volume spikes or brand-new merchants trigger closer scrutiny. Steady growth is good; 10x overnight growth is suspicious.

Ideal: 6+ months processing history, steady month-over-month growth under 30%, consistent volume patterns

What Your Score Means

Real merchant examples at each score range

Score: 85/100

LOW RISK - Excellent

Example Merchant: SaaS company, 0.3% chargeback rate, 12 months processing history, $50K/month volume, PCI compliant, 3DS enabled

What This Means: You'll get approved by 95%+ of processors. Stripe, PayPal, Square, Adyen: take your pick. Low reserve requirements, fast payouts, minimal scrutiny. Your biggest challenge is negotiating better rates.

Score: 72/100

MEDIUM RISK - Good

Example Merchant: E-commerce, 0.8% chargeback rate, 6 months history, $30K/month, some fraud tools but not 3DS, medium-risk industry

What This Means: You'll get approved by 60-70% of processors. Expect higher scrutiny, rolling reserves (5-10%), and conditional approvals. Focus on getting chargeback rate under 0.5% to unlock better options.

Score: 48/100

HIGH RISK - Needs Immediate Attention

Example Merchant: CBD merchant, 1.8% chargeback rate, 3 months history, $15K/month, minimal fraud tools, unclear refund policy

What This Means: Mainstream processors will reject you. Approval rate under 30%. You need specialized high-risk processors with 10-15%+ reserves, longer payout delays, and higher fees. Priority: Get chargebacks under control immediately.
