Frequently Asked Questions (E-Commerce Development)
Why build an e-commerce store with Next.js instead of standard Shopify themes or WooCommerce?
Standard Shopify themes and WooCommerce plugins suffer from heavy render-blocking scripts that cause 3-to-5-second page loads on mobile. Next.js delivers sub-second page transitions, instant client-side product filtering without reloads, and 98+ Core Web Vitals. Every 1-second improvement in e-commerce load time directly increases checkout conversions by 7% to 15%.
How much does custom Next.js e-commerce development cost in Mumbai and India?
A headless Next.js e-commerce storefront integrated with Shopify, Medusa, or custom Node.js APIs starts from ₹85,000 ($1,199 USD). Large-scale multi-vendor marketplaces with complex inventory sync, localized pricing, and custom payment splits range from ₹1,80,000 to ₹3,50,000 ($2,399 to $4,500 USD).
Which payment gateways do you support for Indian and international customers?
We integrate Razorpay, Cashfree, and Paytm for seamless UPI, net banking, and EMI checkouts in India, alongside Stripe, PayPal, and Apple Pay / Google Pay for international global transactions.
Can Next.js e-commerce handle high traffic spikes during festive sales?
Yes. By combining Next.js Static Site Generation (SSG) with edge caching on Vercel or Cloudflare, your product catalog pages can easily withstand millions of simultaneous visitors without server crashes or slow response times.
