The basics

Which e-commerce platform is right for my business?

Shopify is usually best for brands that want to launch quickly and manage the store easily. WooCommerce suits businesses already on WordPress who want more control. A custom store makes sense for complex B2B pricing, marketplaces or deep ERP integration. We recommend the platform after understanding your products and plans.

Whatever the platform, a store only works if people find it, so we set up SEO, analytics and ad tracking before launch.

FAQs

Ecommerce website development: common questions

How much does an ecommerce website cost in India?

It depends on the platform (Shopify, WooCommerce or custom), the number of products, payment and shipping integrations, and any custom features. We give a fixed quote after a free call. Platform and app fees are separate.

Shopify or WooCommerce?

Shopify is quicker to launch and easier to run. WooCommerce gives more control and no platform fee, but needs more upkeep. We'll recommend one after a free call.

Can you connect the store to our inventory or ERP?

Yes. We build inventory and ERP software ourselves, so syncing stock and orders is something we do well.
