I want to add a complete UPI flow to my platform so that I can both collect money from customers and disburse payouts to partners through the same integration. Nothing else—no PayPal, Stripe, or Square—just a clean UPI set-up that handles incoming and outgoing transactions reliably. You will configure the gateway, connect it to my existing back-end, and make sure I can track each transaction with real-time status updates, webhooks or callbacks, and clear error handling. The work is urgent: I need the solution up and running as soon as possible, thoroughly tested in sandbox and then live. Once everything is in place I should be able to: • Receive UPI payments initiated on web or mobile. • Trigger UPI payouts automatically or from an admin panel, with confirmation of success/failure. Please propose the tech stack you prefer, outline any API keys or documentation you will need from me, and include an estimated timeline so we can get started immediately.

I would prefer you go with Razorpay as their sign up is very straight forward and requires minimal verification. That said, the stack will depend on your existing application and I’m open to everything. If you require a separate payments dashboard I prefer React with Node and web-sockets for secure and immediate updates. If provided more details I can come up with a better PoC for you to go through. Looking forward to working with you!
