I’m ready to take my physical-goods store online and need a full-featured e-commerce app that runs smoothly on both iOS and Android. Shoppers anywhere in the country should be able to browse our catalogue, add items to a cart, choose a shipping option, and check out seamlessly. Key requirements • Native or high-performance cross-platform build (iOS + Android) • Secure payment gateway integration covering credit/debit cards, popular digital wallets, and direct bank transfers • Real-time inventory sync with my existing stock system • Order tracking visible to customers and to staff in an admin panel • Push notifications for order status, promotions, and back-in-stock alerts • Clean, modern UI that carries our brand style I will supply product data, branding assets, and shipping rates. You will deliver the complete source code, compiled apps ready for store submission, and brief hand-over documentation so my team can manage routine updates. Please outline your preferred tech stack, any relevant store apps you’ve shipped, and an estimated timeline from kick-off to launch.
