Questions

Payments & fintech: what people ask

Which payment gateway should we use?

In India, Razorpay or Cashfree usually fit best. For international customers, Stripe or PayPal. We compare fees, methods and settlement times for your case.

Do card details touch our servers?

No. We use the gateway's hosted checkout or secure fields, so card numbers go straight to the gateway and your compliance scope stays small.

Can you build a wallet or lending app?

Yes, on top of licensed partners such as banks, NBFCs or payment aggregators. We build the product, ledger and integrations, and tell you early which licences or partners the idea needs.
