It also integrates trusted payment gateways (Stripe, PayPal, Razorpay), third-party APIs, analytics tools, and backend systems. With optimized caching, background syncing, and strong SEO support, a PWA eCommerce app provides a seamless, fast, and engaging shopping experience across mobile, tablet, and desktop devices—while remaining cost-effective and easy to maintain.
