Custom E-Commerce Store With UPI

I need a full-featured e-commerce site that can take real-time UPI payments at checkout. The store itself can be built in the framework you’re most comfortable with—WooCommerce, Shopify, Laravel, React + Node, or another solid stack—as long as it stays lightweight and easy for me to manage later.

Core scope
• Product catalogue and cart flow that work smoothly on desktop and mobile
• UPI payment gateway integration (Google Pay, PhonePe, BHIM, etc.) with live and sandbox keys fully tested
• Order tracking and confirmation emails triggered automatically after a successful transaction
• Clean admin panel where I can add or edit products, prices, and stock without touching code

Future-proofing
I’m not enabling PayPal, Stripe, or Square right now, but the codebase should leave room to plug those in later without a full rebuild.

Acceptance criteria
1. A test transaction completes end-to-end via UPI and registers in the order table.
2. Responsive UI scores 90+ on Lighthouse mobile.
3. Clear hand-off: zipped source, database schema, and a plain-English setup guide.

Tell me which tech stack you’d like to use and an estimated timeline, and I’ll get product details to you right away.
