Why Businesses Choose Us
30+ businesses trust Prominent TechnoLabs — here is what sets us apart.
Security-First Integration
We follow PCI-DSS guidelines, use server-side token handling, never log card data, and configure Content Security Policy headers for payment pages.
End-to-End Ownership
We handle the complete integration — from gateway account setup to webhook handling — so you do not need to coordinate between multiple vendors.
Multi-Currency & Multi-Gateway
Support for INR, USD, GBP, EUR and more. We also build failover logic so if one gateway is down, your checkout automatically switches to a backup.
Razorpay is our top recommendation for businesses primarily targeting Indian customers — it supports all Indian payment methods (UPI, Net Banking, wallets) and has the best developer experience. Stripe is recommended for international or SaaS businesses with global customers.
