How Much Does an Ecommerce Website Cost in 2026? Full Guide

Ask three agencies what an online store costs and you will get three numbers that do not overlap. That is not evasion. "Ecommerce website" describes both a forty-product boutique running on a themed Shopify install and a multi-warehouse operation with a live ERP integration, and those are not the same object.

What follows is a straight answer to a question that usually gets a vague one: what drives the price, what the realistic ranges look like by platform and store size in 2026, and which costs turn up after launch that almost nobody quotes for.

Cost by platform

The platform decision sets the floor and the ceiling of everything that follows, so start there.

Shopify

Shopify is hosted, which means the platform handles infrastructure, security patching, PCI compliance and uptime. You are renting capability rather than building it.

A lightly customised premium theme with your branding, product data imported and payments and shipping configured is the low end — a matter of days rather than weeks of work. A genuinely custom storefront built on Shopify, with a bespoke design, custom product configurators and integrations into your other systems, sits considerably higher and takes weeks.

The trade-off is honest: fastest route to a working, secure store, at the price of a monthly subscription and a design ceiling you eventually notice.

WooCommerce on WordPress

WooCommerce is open source, so licensing is not the cost — the build is. Expect broadly similar build budgets to Shopify for equivalent complexity, sometimes a little lower for standard requirements and higher for unusual ones, because you are assembling more of the machinery yourself.

Where the numbers genuinely diverge is over time. You own the stack, which means you also own the maintenance: hosting, updates, security, plugin conflicts. Budget for that as a real line item, not a hope. It suits businesses that need content and commerce in the same system, or want data and infrastructure entirely under their own control.

Custom builds

Building the commerce layer from scratch — a bespoke application rather than a platform — is the most expensive route and the right one far less often than people expect. It earns its cost when your business model does not fit a product-and-cart shape: complex B2B pricing tiers, quote-based ordering, dealer portals, subscription logic no plugin handles, or a catalogue whose scale breaks off-the-shelf tooling.

If your requirements can be met by a platform, a custom build is an expensive way to end up in the same place. If they cannot, no amount of plugin stacking will rescue you, and the plugin stack will cost more in the long run anyway.

What actually drives the price

Two stores on the same platform can differ in cost by a factor of five. These are the variables that do it.

• Catalogue size and structure. Forty simple products is a different job from four hundred with size, colour and material variants, per-variant imagery and stock rules. Variant complexity, not raw product count, is what moves the number.
• Design origin. A configured premium theme, a heavily customised theme, and a design drawn from scratch to your brand are three distinct price bands.
• Integrations. Every system the store must talk to — accounting, inventory, ERP, CRM, fulfilment, email — is its own small project. Integrations are the most commonly underestimated line on any ecommerce quote.
• Payments and shipping rules. One gateway and flat-rate shipping is simple. Multiple currencies, regional tax handling, live carrier rates and split fulfilment are not.
• Content readiness. If product copy, photography and specifications exist in clean, structured form, migration is mechanical. If they live in a spreadsheet nobody has updated since 2023, someone is doing that work and it is billable.
• Languages and markets. Multilingual and multi-currency selling multiplies content work, testing and ongoing maintenance.

Realistic budgets by store size

Rather than quote figures that vary wildly by market and scope, here is how to size your own budget honestly.

A first store, one market

Under a hundred products, one language, one currency, standard payments and shipping, a customised premium theme. This is the smallest sensible ecommerce project, measured in days or a small number of weeks. Anything quoted dramatically below the market rate for this is usually a theme installed with your logo dropped in and no thought given to how anyone actually buys.

An established retailer moving online properly

Several hundred products with real variant complexity, a custom design, one or two integrations, and a considered content and SEO migration from an existing site. This is the most common serious project and the band where the biggest quality gap between suppliers shows up.

Multi-market or B2B

Multiple languages and currencies, tiered or account-specific pricing, ERP or inventory integration, large catalogues, dealer or wholesale portals. Weeks to months, and the cost is dominated by integration and data work rather than by design.

If you are weighing platform against platform at this stage, our comparison of Shopify builds against fully custom web programming is the more useful next question than price alone — the right platform makes the budget question much easier to answer.

The costs nobody puts in the quote

The build is the visible number. These are the ones that decide the real cost of ownership.

• Platform subscription and transaction fees. Monthly on every hosted platform, plus a percentage of every sale through your payment processor.
• Apps and extensions. Reviews, subscriptions, advanced search, loyalty, upsells — most are monthly, and a stack of small subscriptions quietly becomes a significant recurring line.
• Maintenance. Updates, security, backups, fixing what breaks when a payment provider changes an API. Real on every platform; unavoidable and larger on self-hosted ones.
• Photography and copy. Consistently the most underestimated cost in ecommerce, and the one with the most direct effect on conversion.
• Getting traffic. A store with no visitors converts nothing. Whatever you budget for the build, plan separately for how people will find it.

Frequently asked questions

Can I build an ecommerce site myself for almost nothing?

Technically yes — a platform subscription and a free theme will produce a functioning store. Whether it sells is a different question. Self-built stores usually fall down on product page quality, checkout friction and mobile behaviour, and those are precisely the things that determine revenue. It is a reasonable way to validate whether people want the product; it is a poor place to stay once they do.

Why do quotes for the same brief vary so much?

Usually because they are not the same brief. One includes design from scratch, content migration, integrations and testing; the other is a theme install. Ask every supplier for a line-item breakdown and the differences resolve quickly.

Is Shopify cheaper than WooCommerce?

Cheaper to start and more predictable to run, because the platform absorbs infrastructure and security. WooCommerce has no subscription but transfers hosting and maintenance to you. Over three years the totals are closer than either camp likes to admit — the honest deciding factor is how much control you need and who is going to maintain it.

How long does an ecommerce build take?

A straightforward first store is a matter of weeks. A custom multi-market build with integrations runs to months, and the timeline is usually set by content and data readiness rather than by development.

How to use these numbers

Decide the platform first, count your variants honestly, list every system the store must talk to, and separate the build cost from the cost of running it. Do that before you ask for quotes and you will get comparable ones — which is the actual problem with pricing an ecommerce site.
