Breaking Points and Limitations

Technical Limits

• UI performance degrades with 1000+ transaction spans (debugging becomes impossible)
• International processing requires additional 1.5% fee planning
• Webhook delivery not 100% reliable under high load
• Fraud detection false positives on high-value transactions

Business Constraints

• Limited to 50 countries for merchant registration
• Chargeback fees accumulate quickly in high-dispute industries
• Enterprise features require significant volume for custom pricing
• Some regions have limited payment method availability

Implementation Success Factors

Must-Do Items

1. Implement proper webhook signature verification
2. Use Stripe tokens instead of storing card data
3. Test with international cards if serving global customers
4. Plan for fraud detection false positives on large transactions
5. Budget for dispute fees in high-chargeback industries

Avoid These Mistakes

• Storing raw payment card data locally
• Ignoring webhook signature verification
• Underestimating international processing fees
• Not testing payment flows with various card types
• Assuming 100% webhook delivery reliability
