Payments — money in, correctly, every time.
A payment integration is more than a pay button: webhooks that confirm payment even when the browser closes, refunds, subscriptions, invoices with the right tax, and reconciliation that matches your bank. I build those for Indian and international gateways.

04 — Questions
about Payments work
Can you fix payments that sometimes fail?
Yes. It is almost always missing webhook handling or a race condition between the redirect and the confirmation. Both are fixable without changing gateway.
Which gateway should I use?
For India: Razorpay or PayU. For abroad: Stripe or PayPal. Many businesses run two and route by customer country.
How is Payments work priced?
A fixed price for a defined scope, or hourly from $10 depending on the stack, always with a written estimate before any work starts.
