Ecommerce Mobile App Payment Integration

I’m building a dedicated mobile shopping app and need it taken from zero to a store-ready release. The must-have is a seamless, fully secure payment gateway—customers should be able to browse products, add them to the cart, then pay without ever leaving the app. I’m flexible on the wider tech stack, though React Native, Flutter, or a comparable cross-platform framework paired with a Node.js or PHP backend would fit neatly into my existing infrastructure.

Key deliverables
• High-fidelity UI/UX for iOS and Android
• Product listing, cart, and checkout flows wired to a live payment gateway (Stripe, PayPal, or a gateway you recommend)
• Admin endpoints or panel so I can add, edit, and track inventory and orders
• Clean, well-documented code pushed to my Git repo plus build instructions
• One short hand-off session to walk me through deployment and future updates

Acceptance criteria
• Payments complete successfully in test and live modes
• Transactions appear in the merchant dashboard with correct order details
• App passes App Store and Google Play review guidelines on first submission

If you have recent e-commerce apps in your portfolio and can start right away, let’s set up a quick call to outline timelines and milestones.
