FAQ
How much does a custom ecommerce website cost?
Pricing depends on scope: a PoC/Prototype starts at $3,000 (21-day delivery), an MVP ecommerce store is $12,000 (60-day delivery), and a complex, full-featured ecommerce platform runs from $20,000 (90-day delivery). We'll help you pick the right tier during the free discovery call.
Can you build a mobile app for my online store, not just a website?
Yes - we build both web and mobile versions of your online store, including a Progressive Web App (PWA) option for cross-platform reach without maintaining separate native codebases.
What technology do you use to build ecommerce platforms?
Our stack includes React.js and Next.js on the frontend, Bootstrap and Tailwind CSS for styling, and Node.js with Express.js, NestJS, and Fastify on the backend. We also use AI-assisted tools like Claude and Cursor to speed up development without sacrificing code quality.
Do you build responsive ecommerce websites that work well on mobile?
Yes, responsive design is included starting from our Basic package - every ecommerce website we build adapts seamlessly to mobile, tablet, and desktop screens.
What's included in the Basic (PoC) package?
The Basic package delivers a working prototype of your online store - responsive design and full source code included - so you can validate your idea before committing to full MVP development. Design customization and content upload are added starting from the Standard package.
Can you integrate payment gateways, inventory, or CRM/ERP systems into my store?
Yes - our ecommerce platforms support secure checkout and payment gateway integration, inventory management, multi-language support, and CRM/ERP integrations for businesses that need more advanced operational tools.
Is this the right gig if I need a multi-vendor marketplace instead of a single store?
This gig is built for single-brand ecommerce websites and online stores. If you're looking for a multi-vendor marketplace where multiple sellers list products, check out our dedicated Marketplace development gig instead.
