Frequently asked questions

What is e-commerce development?

Building online stores with features like product catalogs, shopping carts, payments, user accounts, and admin dashboards for managing sales.

Why choose custom e-commerce development over platforms like Shopify?

Basic stores take 3–6 months; advanced marketplaces often 6–12 months.

What is the typical cost for e-commerce development?

Simple sites range from $20,000–$80,000; complex platforms commonly cost $100,000–$400,000+.

Can e-commerce sites handle high traffic?

Yes — built with scalable architecture, caching, and cloud hosting to manage sales peaks without crashes.

Does it include mobile optimization?

Yes — responsive design ensures seamless shopping on phones, where most e-commerce traffic comes from.

Integrated with gateways like Stripe or PayPal, plus PCI compliance, SSL, and fraud detection for safe transactions.
