Why payment integration deserves careful testing
A payment gateway that fails intermittently, times out, or handles a specific card type incorrectly costs sales silently — customers don't complain, they just leave and buy elsewhere. Payment integration needs to be tested against real-world conditions, not just the gateway's sandbox mode, which often doesn't surface the edge cases that show up in production.
Security and compliance matter as much as reliability — handling payment data incorrectly creates real liability. We follow proper PCI-compliant practices, generally by not storing sensitive card data directly and relying on the gateway's secure tokenisation.
What's included
Our process
Gateway selection
Right payment methods chosen for your customer base.
Integration
Checkout connected to the gateway with proper error handling.
Testing
Real transactions tested, not just sandbox mode, before launch.
Compliance check
PCI-compliant practices verified before going live.
Monitoring
Payment success rate tracked after launch to catch issues early.
Who this is for
Any business building or upgrading an online store's checkout, especially if currently experiencing unexplained payment failures or wanting to add more payment methods (UPI, wallets) to reduce checkout friction.
Engagement & pricing
Priced per project based on number of payment methods and integration complexity. Gateway transaction fees are separate, charged by the payment provider directly.
One more thing worth knowing
We also review payment success rates periodically after launch, since a gateway that worked well initially can develop issues with a specific card type or bank that's easy to miss without ongoing attention. A slow decline in one payment method's success rate rarely announces itself loudly.
Frequently asked questions
Depends on your customer base — cards and UPI cover most Indian consumers; wallets and net banking add convenience for specific segments. We'll recommend based on your actual customer data where available.
No — proper practice is relying on the gateway's secure tokenisation rather than storing sensitive card data directly, which is both safer and reduces your compliance burden.
We test with real transactions using small amounts or the gateway's test-mode with realistic scenarios, going beyond the basic sandbox demo to catch edge cases.
Proper failure handling is built in — clear messaging to the customer and a way to retry, rather than leaving them uncertain whether the payment went through.
Yes — additional payment methods can be integrated incrementally without rebuilding the whole checkout.
