eCommerce Website Cost in 2026: Build, Platform and Running Costs
What an online store really costs in 2026: build ranges from published data, platform and payment fees for WooCommerce, Shopify and Adobe Commerce, and running costs.
An eCommerce website has two price tags: what it costs to build and what it costs to run every month. Clutch's pricing data, based on client reviews, puts the average eCommerce development project at $51,943, yet it also notes that most reviewed eCommerce builds cost less than $10,000. On top of the build you pay platform or hosting fees, app and extension licences, and payment processing on every order. This guide breaks down the full eCommerce website cost so you can compare platforms and agency quotes on the same basis.
The layers of eCommerce website cost
Most budgeting mistakes come from pricing only the build. A store has at least six cost layers, and several of them scale with your sales:
| Cost layer | One-time or recurring | What drives it |
|---|---|---|
| Platform or licence | Recurring | Plan tier on hosted platforms, or licence for enterprise software |
| Hosting | Recurring | Traffic, catalogue size and performance needs (self-hosted platforms only) |
| Design and development | One-time, plus change requests | Custom design, number of templates, integrations, data migration |
| Apps, extensions and themes | Mostly recurring | Features you add: subscriptions, reviews, search, B2B pricing |
| Payment processing | Per transaction | Card fees and, on some platforms, extra fees for third-party gateways |
| Maintenance and growth | Recurring | Updates, security patches, new features and performance work |
Platform fees compared
Platform choice sets your recurring baseline. Here is what the vendors publish:
| Platform | Platform fee | Other published costs |
|---|---|---|
| WooCommerce (WordPress) | Free core plugin, no revenue share | Hosting of $25 to $350 a month for most stores, extensions of $29 to $299 a year each, WooPayments at about 2.50% to 2.90% plus 30 cents per transaction |
| Shopify | Monthly plans, priced in local currency | Extra transaction fee when you use a third-party payment provider: 2% on Basic, 1% on Grow, 0.6% on Advanced and 0.2% on Plus |
| Adobe Commerce (Magento) | Licence quoted by Adobe | WooCommerce's own comparison table lists Adobe Commerce at roughly $22k to $125k+ a year; Magento Open Source has no licence fee |
| Webflow eCommerce | Site plans with item limits | Webflow lists a 2% transaction fee on its Standard eCommerce plan and 0% on Plus and Advanced, with item limits of 500, 5,000 and 15,000 |
Two notes. First, Shopify shows prices in the visitor's currency, so check its pricing page from your own country. WooCommerce's comparison table lists Shopify Basic at $29 a month and Shopify Plus from $2,300 a month, but that is a competitor's summary, so confirm on Shopify's site. Second, enterprise licences are negotiated, so treat any published range as indicative only.
Which platform fits which budget
The cheapest platform on paper is not always the cheapest store to run. Match the platform to your stage and team:
New or small catalogue
A hosted platform keeps fixed costs predictable and removes server work. You pay a monthly plan and app fees, and the platform handles hosting, security patches and checkout uptime. This suits founders who want to sell quickly and do not have a developer on call.
Content-led or WordPress-based business
If your marketing already runs on WordPress, WooCommerce lets you add a store without a second system. You gain full control over code and data, but you take on hosting, updates and extension compatibility. Budget for a developer or maintenance plan from the start.
Large catalogue, B2B or complex pricing
Stores with many SKUs, customer-specific pricing, several warehouses or multiple storefronts often outgrow simple plans. Magento Open Source or Adobe Commerce, or an enterprise plan on a hosted platform, can handle that complexity, but the build, hosting and maintenance costs rise with it. Ask vendors to show stores with similar order volumes before you commit.
Whichever route you choose, model costs at today's revenue and at two or three times that level. Percentage-based fees that look small at launch can become one of your largest overheads as the store grows.
Build costs: what agencies charge
The build is where quotes vary most. Clutch's eCommerce data says most eCommerce development companies on its platform charge between $24 and $49 per hour, and the typical project timeline in reviews is 9 months. That long timeline reflects larger builds with integrations, not a simple theme setup.
On Trusted IT Firms, 105 companies list eCommerce development. Of those that publish an hourly band, 28 charge $1 to $25, 47 charge $25 to $75 and 12 charge $75 to $250. Rates alone do not decide cost. These scope items usually add the most hours:
- Custom theme design versus adapting a premium theme.
- Catalogue complexity: variants, bundles, configurable products and B2B price lists.
- Integrations: ERP, inventory, shipping carriers, tax engines, marketplaces and CRM.
- Data migration: products, customers, orders and URL redirects from an old store.
- Checkout changes: custom fields, local payment methods and fraud tools.
- Multi-store or multi-currency setups.
Typical build phases to see in a quote
A clear eCommerce estimate breaks the work into phases so you can see where the hours go and what you could defer:
- Discovery: requirements, catalogue structure, integration mapping and a written scope.
- Design: home, category, product, cart and checkout templates for desktop and mobile.
- Development: theme build, app or extension setup, custom features and integrations.
- Migration: products, customers, orders and redirects from the old store.
- Testing and launch: payment tests, tax and shipping checks, speed checks and go-live support.
If a quote shows only one total, ask the vendor to split it this way before you compare it with others.
A published example of first-year store costs
WooCommerce's pricing page includes total cost of ownership examples supplied by an agency partner. One is a boutique luxury goods brand in Europe with about $2M in annual revenue and a highly customised front end. The published breakdown lists $70,000 for initial development, $15,000 for functional additions and maintenance in year one rising to $35,000 a year afterwards, $3,000 a year for third-party services, $300 for hosting, $300 for premium plugins and about $50,000 in payment fees. The total comes to roughly $139,000 in the first year and $89,500 in later years.
Two lessons stand out. Payment fees were one of the largest single lines, and ongoing development was larger than hosting by a wide margin. Your numbers will differ, but the shape of the budget is typical of a growing store.
Hidden and recurring costs to plan for
- Payment processing. Every order carries a card fee. On Shopify, using a third-party gateway also adds the plan-based transaction fee listed above.
- App and extension creep. Stores often add reviews, search, subscriptions, loyalty and email tools after launch. Each adds a monthly or yearly licence.
- Theme renewals and updates. Premium themes and extensions usually need renewed licences for updates and support.
- Hosting upgrades. On self-hosted platforms, traffic peaks during sales can require a larger plan.
- Security and upgrades. Platform and extension updates need testing so they do not break checkout.
- Marketing. Traffic does not arrive on its own. Budget for SEO, paid ads or email marketing from day one.
How to estimate your own budget
- Estimate year-one sales. Many costs scale with revenue, so this number drives your payment and platform fees.
- Shortlist two platforms. Compare the platform fee, payment fees at your expected volume, and the apps you would need.
- List must-have integrations. These are the biggest variable in build quotes.
- Ask three agencies for itemised estimates covering design, development, migration, testing and launch.
- Add a 12-month running budget for apps, hosting, maintenance and growth work.
- Review the total cost of ownership over two or three years, not just the launch quote.
Checklist before you sign
- Does the quote include product and customer data migration and redirects?
- Which paid apps or extensions does the design depend on, and what do they cost each year?
- Who owns the theme code, store account and payment accounts?
- Is checkout tested on mobile with your real payment methods?
- What is the monthly maintenance price, and what does it cover?
- How will platform and extension updates be tested before they go live?
- Can the vendor show stores of a similar size and complexity?
