How Much Does an Ecommerce Website Cost?

The build fee is the number everyone asks for and the least useful one to know.

An online store isn’t a website you pay for once. It’s a website plus a platform subscription plus apps plus payment processing plus maintenance — and that second column runs every month for as long as the store exists. Plenty of businesses budget carefully for the build and get blindsided by the running costs.

One breakdown puts the framing well: the common question is “what does a Shopify store cost to build,” when the more useful question is “what will this store cost me to launch, run, and improve over the first year”.^[1]

Here’s both numbers. For brochure-site ranges (not stores), see how much a website costs. For what moves a design quote in general, see web design pricing.

Build cost by project type

Ecommerce development in 2026 ranges from around $1,000 for simple template stores to $50,000+ for fully custom builds.^[2] The tiers within that:

DIY setup: ~$50–$500 for the first year

Setting things up yourself runs roughly $50 to $500 for the first year excluding subscriptions — a free or low-cost theme, a domain, one or two paid apps, and your time.^[3]

Genuinely viable if your catalog is small and design needs are basic. The cost is your hours, and store setup absorbs more of them than people expect.

Template-based professional build: ~$3,000–$10,000

Template-based stores using pre-made themes typically cost between $3,000 and $10,000 — suited to startups testing product-market fit and small businesses with straightforward catalogs.^[2]

More specifically for Shopify, a professionally configured pre-built theme typically falls in the $3,000 to $5,000 range, often involving 50 to 100 developer hours.^[1]

This tier is the right answer for more businesses than choose it.

Semi-custom: ~$10,000–$30,000

Semi-custom projects start with an existing theme but include developer work to adjust layouts, add features, or integrate third-party tools — the route growing retailers take when they need branded design without rebuilding from scratch.^[2]

Fully custom theme work sits around $10,000 to $20,000.^[1]

Fully custom: $40,000+

Fully custom builds cost anywhere from $40,000 to $150,000 or more^[2], with larger Shopify Plus implementations reaching $25,000 to $100,000+ and often requiring 300 to 600+ developer hours.^[1]

By business size

A useful cross-check: small businesses typically spend $2,000–$10,000 on setup with $30–$500/month ongoing; mid-size brands $10,000–$50,000 setup and $500–$2,000/month; enterprise $100,000–$500,000+ and $5,000–$20,000+/month.^[4]

Hourly rates, if you’re being billed that way

Junior developers charge $25–$45/hour, mid-level $45–$90/hour, senior specialists $90–$160/hour, with US and UK agency rates running $120–$200/hour including project management and QA.^[5] Freelance Shopify developers generally sit in the $35–$100/hour band, agencies $100–$200/hour.^[3]

The practical guidance: for a contained task like a section update or app integration, a mid-level freelancer is reasonable; for a full store build, a fixed-price agency engagement typically produces more predictable results.^[5] Related: freelancer vs agency.

The running costs nobody budgets for

This is the section worth reading twice.

Most cost discussions stop at the build fee, leaving out the expenses that appear the moment the store goes live: platform subscription, paid apps, maintenance, email tools, payment fees, and support work.^[1]

Platform subscription. Shopify’s published pricing lists Basic from $29/month billed yearly, Grow from $79/month, and Advanced from $299/month.^[6] Self-hosted platforms like WooCommerce are free to install, but the real cost comes from hosting, development, updates, and maintenance.^[4]

Apps and plugins. The cost that compounds quietly. Each app is a monthly fee, and stores accumulate them. Worth knowing: check whether native platform features cover the need before adding a paid app — platforms added serious functionality through 2025 and 2026, including native subscriptions, better discount logic, and improved analytics, making many third-party apps redundant.^[3]

Payment processing. A percentage of every sale, forever. On meaningful volume this dwarfs everything else on this list.

Domain and hosting. Domains typically $10–$50/year; shared hosting $5–$20/month for low-traffic sites.^[4]

Maintenance and support. Updates, security, fixes, small changes — see maintenance & support.

Email and marketing tools. Usually priced by list size, so this grows as you succeed.

Integrations. Connecting to your existing systems isn’t free — even a straightforward CRM integration can run from $500 up to $2,000.^[3]

What moves the build number most

Design approach. Customizing a premium theme adds $1,000–$4,000 to a base build. A completely original design from scratch — wireframes, UI design, then development — adds $2,000–$8,000 for the design work alone, before any code.^[5]

Catalog size and complexity. Twenty products is a different project from two thousand, especially with variants, sizes, and configurations.

Product data quality. Underrated. If your product information lives in inconsistent spreadsheets, someone has to clean it, and that’s real billable hours before anything gets built.

Integrations. ERP, CRM, inventory, accounting, fulfillment. Each connection is scoped work.

Custom business logic. Custom development becomes the right path when the model pushes beyond theme limits — unique landing page structures, advanced merchandising rules, custom filtering, subscription flows, or integrations beyond standard app setup.^[1] That’s often ecommerce development or custom web applications territory.

B2B requirements. Customer-specific pricing, quote workflows, purchase orders, tiered accounts. Substantially more complex than standard retail.

Timelines

Semi-custom stores need 1 to 2 months for meaningful customization. Full custom builds take 3 to 6 months for design, development, testing, and revisions. Marketplace or enterprise solutions require 6 to 12 months.^[2]

With an important caveat: these timelines assume clear requirements and timely feedback — projects extend when scope keeps changing or stakeholders can’t make decisions.^[2]

Choosing the right tier

Template build if: you’re validating demand, your catalog is straightforward, and your customer journey follows familiar ecommerce patterns. A theme-based build is the better budget choice when the catalog is straightforward and the team doesn’t need custom business logic behind the storefront.^[1]

Semi-custom if: you have real brand guidelines, some specific functional requirements, and enough revenue that conversion improvements justify the spend.

Fully custom if: your business model genuinely doesn’t fit standard patterns — B2B pricing rules, complex subscriptions, marketplace mechanics, or integrations that can’t be handled by apps.

A useful framing from the same source: if you have strong brand guidelines and specific visual requirements, a custom theme build is usually the right call; if you’re launching to test product-market fit, a template gets you live and selling.^[5]

The most common expensive mistake is building fully custom before knowing whether the products sell. Custom is the right answer for a proven business with constraints a platform can’t meet — not for a launch. What the storefront itself should prioritize once you’re live is covered in best ecommerce websites.

The short version

DIY: ~$50–$500 first year plus your time; template build: ~$3,000–$10,000; semi-custom: ~$10,000–$30,000; fully custom: $40,000+
Small business total setup typically $2,000–$10,000 with $30–$500/month ongoing
Developer rates: freelance ~$35–$100/hour, agencies ~$100–$200/hour
The build fee is roughly half the picture — subscription, apps, payment fees, and maintenance run forever
Check native platform features before paying for apps; platforms absorbed a lot of app functionality recently
Custom design adds $2,000–$8,000 before any development begins
Messy product data is a real, unbudgeted cost
Template first if you’re validating; custom only once constraints are proven
