The cost of an eCommerce website varies wildly based wildly on the scope of the project. Let's break down the tiers.
Tier 1: Basic Template Dropshipping (₹15,000 - ₹50,000)
This usually involves someone buying a $50 Shopify or WordPress theme, changing the logo, and handing it over to you. It's cheap, but it's not custom, not optimized, and usually very slow.
Tier 2: Professional Custom Build (₹1,50,000 - ₹5,00,000)
This is where real businesses operate. This includes custom UX/UI design tailored to your specific user journey, robust integrations with your inventory, and significant technical SEO implementations.
Tier 3: Enterprise Headless Commerce (₹10,00,000+)
For large-scale brands requiring sub-second load times and massive scale, a headless architecture utilizing Next.js and specialized backends is necessary.
