The short answer

An ecommerce website can cost anywhere from a few hundred dollars to well over $20,000 to build, plus monthly running costs. Shopify’s September 2026 cost guide puts prebuilt themes at $0 to $500 and custom-built ecommerce development at $2,000 to $20,000 or more, depending on complexity. WebFX’s web design pricing guide puts functionality, mostly ecommerce and online payments, at $5,000 to $10,000 of a website project’s cost. Ranges vary widely by provider and region.

Where your store lands depends on four things: the platform, how many products and options you sell, how custom the design and checkout need to be, and how many other systems the store must connect to. Running costs, including platform fees, card processing, apps and upkeep, continue every month after launch.

Three typical levels of ecommerce site

Theme-based starter store

A hosted platform, a free or premium theme customized with your branding, a modest catalog, standard checkout and shipping. Low build cost; much of the work is product entry and photos.

Professionally designed store

Custom design on a theme or framework, structured collections and filters, content pages, email marketing setup, reviews, and a few integrations such as accounting. The most common choice for established small businesses.

Custom or integrated store

Custom functionality such as product builders, B2B pricing, subscriptions or multi-store, plus integration with ERP, inventory, CRM or fulfillment systems. Highest cost and longest timeline.

Shopify’s guide estimates total monthly running costs on its platform at roughly $30 to $100 for a solo seller, $100 to $500 for a growing business and $500 to $2,500 or more for an established merchant. Treat vendor figures as a starting point, since each vendor frames costs around its own product.

Platform costs compared

Platform fees from each vendor’s pricing page, as of 2026:

  • Shopify: Basic $39, Grow $105 and Advanced $399 a month on monthly billing ($29, $79, $299 billed yearly). Shopify Plus from $2,300 a month. Online card rates 2.5% to 2.9% plus 30 cents with Shopify Payments.
  • BigCommerce: Core $39, Growth $105 and Scale $399 a month on monthly billing ($29, $79, $299 billed yearly), each tied to a level of annual online sales; Performance from $1,499 a month billed yearly on contracted terms, which Scale stores move to automatically at $2 million in trailing twelve-month sales.
  • WooCommerce: the plugin is free. You pay for hosting suited to a store, paid extensions and maintenance. WooPayments charges 2.9% plus 30 cents for US cards.
  • Wix: its Core, Business and Business Elite plans accept payments; Wix notes prices vary by location.
  • Magento (Adobe Commerce): the open-source edition is free to download but needs capable hosting and specialist developers. The licensed Adobe Commerce edition is priced by quote. Generally suited to large or complex catalogs.

What drives the build price

  1. Number of products and variants. Ten products can be entered by hand. Thousands need imports, data cleanup and good filtering.
  2. Design. A lightly branded theme costs a fraction of a fully custom design with custom page templates.
  3. Product complexity. Personalization, configurators, bundles, subscriptions and made-to-order options add development time.
  4. Checkout and pricing rules. Customer-specific pricing, wholesale tiers, quotes, minimum orders or custom checkout fields.
  5. Integrations. Syncing orders, inventory and customers with accounting, an ERP, a warehouse or a CRM is often the single biggest cost driver.
  6. Migration. Moving products, customers, orders and SEO from an old platform, with redirects for every URL.
  7. Content. Product descriptions, photography and category copy. Unique content takes time but helps both sales and search.
  8. Shipping, tax and international. Multiple warehouses, freight, multi-currency and duties all add setup.

Two example scopes

A boutique with 60 products. A hosted platform on a premium theme, branded to match the shop, with collections by category, size and color variants, local pickup and shipping rules, a reviews app and email sign-up connected to an email marketing tool. Most of the effort goes into photos and product copy. This sits near the theme-based end of the published ranges, and running costs are mostly the plan, processing and two or three apps.

A distributor with 4,000 parts and trade accounts. A platform with strong B2B features, customer-specific price lists, quotes and payment on account, faceted search across technical specs, and a two-way sync with the ERP for stock, prices and orders. Data cleanup and the integration are the largest pieces of work. This lands at the custom end, and the timeline depends mostly on the ERP connection.

Running costs after launch

  • Platform or hosting fees, monthly or yearly.
  • Card processing on every order, which grows with sales.
  • Apps or extensions, often billed monthly or yearly.
  • Maintenance: updates and testing on WooCommerce or Magento; theme and app checks on hosted platforms.
  • Email marketing software and business email.
  • Marketing to bring in traffic: search, ads, email and social. For most stores this exceeds the cost of the site itself.

How to budget without overspending

  1. Separate must-haves from later. Launch with what you need to take orders well, then add features once real customers show you what matters.
  2. Use built-in features before apps, and apps before custom code.
  3. Price integrations early. If your store must sync with accounting or an ERP, get that scoped before choosing the platform, because connector options differ.
  4. Budget for year one, not launch day. Add 12 months of platform fees, processing, apps, upkeep and marketing to the build cost.
  5. Get like-for-like quotes. Ask each provider for the same scope: products to load, templates, integrations, migration and post-launch support.

Questions to ask a provider

  • Which platform do you recommend for us, and why that one?
  • Who owns the site, theme and accounts, and can we edit it ourselves?
  • What is included: product entry, migration, redirects, training?
  • Which apps or extensions will we pay for after launch?
  • How long will it take, and what do you need from us?
  • What happens after launch if something breaks?

How much does a custom ecommerce website cost?

Shopify’s 2026 guide puts custom-built development at $2,000 to $20,000 or more. Integrations, custom features and large catalogs push projects higher.

What are the monthly costs of running an online store?

Platform or hosting fees, card processing, apps, email tools, maintenance and marketing. Shopify estimates $30 to $100 a month for solo sellers up to $500 to $2,500 or more for established merchants.

Is WooCommerce cheaper than Shopify?

The plugin is free, but hosting, extensions and maintenance cost money. Totals are often closer than expected; the right choice depends on who maintains the store and how custom it needs to be.

How long does it take to build an ecommerce website?
