E-commerce website development builds online stores that sell — custom storefronts, product catalogs, secure checkout, and payment and shipping integrations on Shopify, WooCommerce, BigCommerce or a custom stack. A professional e-commerce build typically costs $2,625 to $11,250+ depending on catalog size and integrations. ReStartWeb AI has built converting stores for US and EU brands since 2016.
A store is only worth building if it converts. We develop e-commerce websites engineered around the buying journey — fast product and collection pages, frictionless checkout, reliable payment and shipping integrations, and clean product data that is ready for SEO. We build on the platform that fits your catalog and margins (Shopify, WooCommerce, BigCommerce or a custom stack), never forcing one tool on every problem.
The Work
Custom Storefront Design & Build
Conversion-focused storefronts from Figma to code — product, collection, cart and checkout templates built for speed and clarity on mobile, where most store revenue happens.
Platform Selection & Setup
We help you choose between Shopify, WooCommerce and BigCommerce based on catalog size, margins and roadmap — then build it right, avoiding app bloat and lock-in.
Payments, Shipping & Tax
Stripe, PayPal, Apple/Google Pay, real-time shipping rates, tax automation and multi-currency — configured, tested and reconciled so checkout just works.
Product Data & Catalog
Clean product structure, variants, bulk import, and SEO-ready product data with Product/Offer schema so listings can win rich results and AI-Overview citations.
Integrations & Automation
ERP, CRM, inventory, email/marketing and analytics integrations; order and fulfilment automation that removes manual work as you scale.
Speed, SEO & Launch
Core Web Vitals tuning, technical SEO foundation, analytics and a monitored launch with 30-day post-launch support.

Frequently Asked
Questions
How much does e-commerce website development cost?
A professional e-commerce store typically ranges from $2,625 for a themed launch to $11,250+ for a fully custom build with B2B flows and integrations. You get a fixed estimate within 24 hours after a short discovery call.
Which platform is best — Shopify, WooCommerce or BigCommerce?
It depends on catalog size, margins and roadmap. Shopify is fastest to launch and lowest-maintenance; WooCommerce gives full control on WordPress; BigCommerce suits larger catalogs and B2B. We recommend the fit for your case rather than forcing one tool.
How long does it take to build an online store?
A themed store launches in 3-4 weeks; a custom store in 5-7 weeks; enterprise/B2B builds are scoped individually. Timeline depends on catalog size, integrations and content readiness.
Do you also do SEO for the store?
Yes. Every build ships with a technical SEO foundation and Product/Offer schema, and we offer dedicated e-commerce SEO to grow organic revenue after launch.
