How Much Does an E-Commerce Site Cost to Build?

An honest breakdown — what's included, what moves the price, and when a custom store beats Shopify for SEO and performance.

For most stores, Shopify is the right answer — and I'll tell you that honestly. A custom e-commerce build makes sense when you need things off-the-shelf platforms make hard: programmatic SEO across thousands of product and category pages, sub-second performance, a bespoke catalogue model, or deep integrations. Here's what a custom, SEO-first online store actually costs, what moves the price, and where the line between "use Shopify" and "build custom" falls.

Typical price range

$10,000 – $30,000A focused catalogue store starts lower; large catalogues with pSEO, custom checkout, and integrations push higher.

What's included

Standard build scope

Catalogue & product model

Product, variant, category, and collection data model with images, attributes, inventory, and pricing. Bulk import and an admin panel for managing the catalogue. Designed so every product and category becomes a fast, indexable page.

SEO-first storefront

Server-rendered product, category, and collection pages with structured data (Product, Offer, BreadcrumbList), clean URL taxonomy, and programmatic SEO across category × attribute combinations. This is the main reason to build custom rather than use a template.

Cart & checkout

Cart, guest and account checkout, and Stripe payment integration with cards and wallets. Tax and shipping calculation, discount codes, and order confirmation. Built for speed and conversion.

Order & inventory management

Order dashboard, fulfilment status, inventory tracking, and customer accounts with order history. Low-stock handling and basic reporting included.

Customer accounts & reviews

Account creation, saved addresses, order history, and a product review system with ratings and schema markup for rich snippets in search results.

Deployment & launch support

Production deployment, Search Console setup, sitemap submission, structured-data validation, and first-crawl monitoring across product and category pages. Staging environment throughout the build.

What moves the price

Cost variables

A few dozen products is straightforward. Thousands of products with complex variants, configurable options, or bundles increase the data model and the pSEO template work — though the marginal cost per product is low once the architecture is in place.

A fully custom store (catalogue, cart, checkout, orders) costs more than a custom Next.js storefront on top of Shopify's or a headless commerce backend. For many stores, headless-on-Shopify is the cost-effective sweet spot — custom front-end performance and SEO without rebuilding commerce primitives.

Stripe card payments are standard. Multiple payment methods, regional gateways, real-time carrier shipping rates, and tax-compliance services (Avalara, TaxJar) each add integration scope.

Selling in multiple languages and currencies adds work across the catalogue (per-language content), URL structure, pricing, and checkout. Two locales adds ~15–20%; broad international support is a significant scope increase.

Recurring product subscriptions, memberships, or a loyalty programme add billing and account-management scope on top of one-off purchases — typically $2,500–$5,000.

My default storefront design is clean and conversion-focused. Bespoke brand design — custom components, motion, art direction — is scoped separately and typically adds $1,500–$3,500.

Scope clarity

What's not included

Ongoing hosting and infrastructure (typically $25–$120/month early on)
Stripe and payment processing fees
Product photography, copywriting, and catalogue content
Shopify or headless-commerce platform subscription fees (if used)
Ongoing SEO content and paid acquisition after launch

FAQ

Common questions about cost

Why build custom when Shopify exists?: For most stores, you shouldn't — Shopify is excellent and I'll say so. Custom (or headless-on-Shopify) makes sense when you need what templates make hard: programmatic SEO across thousands of pages, sub-second performance scores, a catalogue model that doesn't fit Shopify's, or deep custom integrations. If none of those apply, a good Shopify theme is the better-value choice.
What is 'headless commerce' and is it cheaper?: Headless means a custom Next.js storefront on top of a commerce backend (Shopify, Medusa, or similar) that handles cart, checkout, and orders. You get custom performance and SEO without rebuilding commerce primitives — usually the cost-effective middle ground between a theme and a fully custom store.
Can the store rank for product and category searches?: That's the main reason to build this way. Server-rendered product and category pages, Product/Offer structured data, clean URL taxonomy, and pSEO across category × attribute combinations mean the catalogue is fully crawlable and built to rank — not dependent on client-side JavaScript that crawlers handle poorly.
What does an e-commerce site cost to build?: A focused custom or headless storefront typically starts around $10,000–$15,000. A larger store with pSEO across a big catalogue, custom checkout, and integrations typically falls in the $18,000–$30,000 range.
