An ecommerce website can cost anything from a relatively small self-built setup to tens of thousands of pounds for a complex store with migrations, integrations, large catalogues, and custom functionality.

For a professionally built ecommerce website in the UK, a useful planning range is around £2,500 to £15,000 for many small and established businesses. More complex ecommerce projects can reach £15,000 to £50,000 or more. Current UK pricing guides show similarly broad ranges because the final cost depends heavily on what the store needs to do.

Our full ecommerce website projects start from £4,500. The final price depends on the catalogue, platform, content, integrations, migration requirements, and functionality involved.

The important question is not simply how many pages an ecommerce website has. A store selling 20 straightforward products can require very different work from a business selling hundreds of products with variants, filters, integrations, subscriptions, trade pricing, or complex fulfilment requirements.

Ecommerce Website Costs at a Glance

The table compares indicative UK website costs, the types of online stores each approach generally suits, and the differences in what is included. These are planning ranges rather than fixed market prices.

Type of ecommerce website	Typical UK planning range	Usually suited to
DIY or lightly configured store	£300 to £2,500	Very small catalogues and businesses able to handle most setup internally
Professionally configured small store	£2,500 to £5,000	Straightforward catalogues using an established ecommerce platform
Tailored ecommerce website	£5,000 to £15,000	Established businesses needing stronger design, content, structure, and functionality
Complex ecommerce project	£15,000 to £50,000+	Large catalogues, migrations, integrations, bespoke functionality, or complex operations

The ranges overlap because the work involved matters more than the label attached to the project. A small catalogue with complicated integrations can require more work than a larger catalogue with clean product data and standard functionality.

What Determines the Cost of an Ecommerce Website?

Several factors have a much greater effect on cost than the number of visible pages.

Platform choice

Shopify and WooCommerce are two common options, but they have different cost structures.

Shopify combines the ecommerce platform and hosting into a recurring subscription. Its UK plans currently start from £19 per month when billed yearly, with higher tiers available as requirements increase.

WooCommerce is free, open-source software for WordPress, but that does not make a complete WooCommerce website free. Hosting, development, extensions, maintenance, payment processing, and other services still carry costs.

The right platform should be chosen around the business, catalogue, internal processes, and longer-term requirements rather than simply the lowest initial fee.

For a fuller comparison, see our guide to Shopify vs WooCommerce.

Number of products, collections, and variants

Catalogue size affects more than product uploads.

Product categories or collections.
Variants such as size, colour, material, or pack quantity.
Filters and product attributes.
Related products.
Product specifications.
Search functionality.
Internal linking between collections and products.
Delivery or compatibility information.

Twenty straightforward products with one option each are considerably easier to prepare than 500 products with multiple variants, inconsistent information, and several collection rules.

Product quality matters too. A catalogue that arrives with accurate names, descriptions, specifications, prices, SKUs, images, and variant information is easier to build than one that first needs restructuring.

Our Ecommerce Product Page Checklist explains the information a useful product page should contain.

Design and customer experience

An ecommerce website needs to support product discovery and purchasing, not simply look good.

Homepage structure.
Collection and category templates.
Product-page layouts.
Navigation.
Search and filtering.
Mobile layouts.
Basket design.
Supporting content.
Delivery and returns information.
Calls to action and trust information.

A largely standard theme with light configuration will normally cost less than a more tailored storefront where several templates and customer journeys are being reconsidered.

Ecommerce functionality

Additional functionality can increase both initial and ongoing costs.

Subscriptions.
Product bundles.
Personalised products.
Advanced filtering.
Trade or B2B pricing.
Customer accounts.
Wishlists.
Booking functionality.
Loyalty schemes.
Multiple currencies or regions.
Specialist delivery rules.

Some requirements can be handled by established platform features or third-party apps. Others require configuration or development.

The important point is to define the functionality before comparing quotes. Two suppliers can both quote for an “ecommerce website” while proposing substantially different amounts of work.

Integrations

An ecommerce website may need to exchange information with other systems.

Accounting software.
CRM platforms.
Email marketing systems.
Shipping providers.
Inventory systems.
Payment providers.
Marketplaces.
Product feeds.
Fulfilment systems.

A standard connection to an established service can be relatively straightforward. More complicated integrations may require additional technical assessment and development.

We provide CRM Setup & Integration using established platforms where the requirements fit our services. Complex custom API engineering is assessed separately.

Content and product data

Product content is a significant part of an ecommerce project.

Product titles.
Descriptions.
Specifications.
Benefits and features.
Collection copy.
Metadata.
Images and alternative text.
Size or compatibility information.
Delivery details.
Returns information.

If all of this is accurate and organised before development starts, the project is easier to plan accurately.

If product information needs to be researched, rewritten, cleaned up, or assembled from several systems, more time is required.

Our £4,500 starting ecommerce package includes up to three standard collection pages and up to 20 standard product listings, with standard product and collection content written or substantially refined from accurate client-supplied facts and source material.

Migration from an existing ecommerce website

Moving an existing store can introduce work that does not exist on a new business launch.

Products and variants.
Collections.
Customer records.
Order history.
Images.
Reviews.
Existing URLs.
Metadata.
Redirects.
Apps or extensions.
Analytics.
Tracking.
Integrations.

An established store may also have existing organic search visibility that needs protecting.

This is one reason a redesign or migration can sometimes cost more than building a simple new store.

If the existing platform remains suitable, Website Redesign may be more appropriate than replacing everything.

SEO and analytics foundations

A new ecommerce website should be structured so that customers and search engines can understand the store.

Logical collection structure.
Crawlable navigation.
Descriptive URLs.
Page titles and metadata.
Internal linking.
Product and collection content.
Redirect planning.
Canonical handling.
Analytics.
Google Search Console.
Relevant structured data.

These foundations are different from an ongoing SEO campaign.

We can build ecommerce SEO foundations into an agreed website project, while broader ongoing search work is covered separately through SEO.

How Much Does a Shopify Website Cost?

The cost of a Shopify website has two main parts: the cost of building the store and the ongoing Shopify-related costs.

The build may include design, theme configuration, product and collection setup, content, navigation, payments, shipping, apps, tracking, and testing.

Shopify then has its own recurring platform subscription. Current UK pricing starts at £19 per month when Basic is billed yearly, while more advanced plans cost more. Apps, premium themes, third-party services, and payment fees can add further costs.

Our Shopify Web Design projects start from £4,500.

For the Shopify-specific breakdown of plans, professional build costs, themes, apps, payment fees, migrations, and ongoing costs, read How Much Does a Shopify Website Cost in the UK?.

How Much Does a WooCommerce Website Cost?

WooCommerce itself can be downloaded and used without a monthly platform subscription, but a commercial WooCommerce website still has real costs.

WordPress hosting.
Design and development.
Premium extensions.
Payment processing.
Security.
Backups.
Maintenance.
Technical support.
Ongoing development.

WooCommerce states that its core platform is free, while hosting and extensions are selected and paid for separately.

This means the useful comparison is not “paid Shopify versus free WooCommerce”. The better comparison is the total cost of building, operating, maintaining, and developing each store.

What Ongoing Ecommerce Website Costs Should You Budget For?

The initial build is only part of the cost of running an ecommerce website.

Platform subscriptions.
Hosting.
Domain renewal.
Premium apps or extensions.
Payment processing.
Maintenance.
Technical support.
Email marketing software.
CRM software.
SEO.
Content.
Product photography.
Additional development.

Some are essential operating costs. Others are optional investments based on the business’s priorities.

Payment processing also needs to be considered separately from website development. The amount normally varies by payment provider, plan, transaction type, and payment method.

When comparing quotes, check which recurring costs are included, which are paid directly to third parties, and which begin after launch.

If you want ongoing help after launch, see Website Maintenance & Support.

Ecommerce Website Redesign and Migration Costs

An existing ecommerce website creates a different project from a new store.

The business may already have customers, search rankings, product URLs, order records, analytics, integrations, and active sales.

A redesign or migration therefore needs to consider what must be retained as well as what needs to change.

Auditing existing content.
Mapping old and new URLs.
Creating redirects.
Migrating products.
Migrating customer or order information where appropriate.
Reconnecting integrations.
Testing payments and shipping.
Preserving important SEO signals.
Checking analytics and tracking.
Planning the launch carefully.

Replacing an established ecommerce website without considering these areas can create unnecessary commercial and search risk.

Why Can Ecommerce Website Quotes Be So Different?

The phrase “ecommerce website” does not describe a consistent amount of work.

One quote may cover little more than installing a theme and configuring a basic store.

Another may include strategy, information architecture, custom design, product content, integrations, migration, SEO foundations, analytics, testing, and post-launch support.

Before comparing prices, compare what is actually included.

Discovery and planning.
Number of design templates.
Product and collection setup.
Copywriting.
Migration.
Integrations.
SEO work.
Analytics.
Testing.
Training.
Revisions.
Launch support.
Ongoing support.

A lower quote is not automatically poor value, and a higher quote is not automatically better. The correct comparison is whether the proposed work matches what the business actually needs.

What Should an Ecommerce Website Quote Include?

A clear ecommerce proposal should explain what is included rather than simply state one total price.

The chosen platform.
Design work.
Number of product and collection templates.
Product population.
Content responsibilities.
Functionality.
Integrations.
Migration.
Mobile layouts.
SEO foundations.
Analytics and tracking.
Testing.
Training or handover.
Revision limits.
Launch support.
Ongoing costs.
Third-party subscriptions or fees.

It should also explain what is not included.

That matters because requirements often expand once catalogue data, integrations, and operational processes are reviewed properly.

Is a Cheap Ecommerce Website Actually Cheaper?

Sometimes.

A low-cost solution can be entirely appropriate for a new business with a small catalogue, straightforward requirements, and enough internal time to manage setup and content.

Paying more does not automatically create a better ecommerce business.

Problems arise when the lower price is achieved by excluding work the business actually needs.

Rebuilding weak catalogue structures.
Reworking product content.
Fixing mobile usability.
Replacing unsuitable apps or extensions.
Correcting missing redirects.
Rebuilding functionality.
Fixing tracking.
Moving platforms earlier than expected.

The right budget should reflect the current business and the requirements likely to matter over the useful life of the website.

Questions to Ask Before Setting Your Ecommerce Website Budget

Before requesting quotes, answer as many of these questions as possible:

How many products will the store launch with?
How many variants do those products have?
How should products be grouped?
Is there an existing website or catalogue to migrate?
Which platform is currently being considered?
Which systems need to connect to the store?
Who will provide product facts, images, prices, and specifications?
Does the website need subscriptions, B2B features, bookings, or other specialist functionality?
Who will manage the store after launch?
What ongoing platform, maintenance, marketing, and payment costs need to be budgeted for?

Clear answers make quotes easier to compare and reduce the risk of important requirements appearing halfway through the project.

Frequently Asked Questions

Do I need to choose Shopify or WooCommerce before requesting an ecommerce website quote?

No. You can explain what you want your online shop to do and ask prospective suppliers to recommend a suitable platform. Useful information includes the types of products you sell, your approximate catalogue size, payment and delivery requirements, and any systems the website needs to connect to. When comparing recommendations, consider platform subscriptions, hosting, maintenance, and future development costs alongside the initial build price.

Can I start with a small ecommerce website and expand it later?

Yes. You can start with a smaller product range and add more products as your business grows. Both Shopify and WooCommerce support expanding your catalogue, although more complicated features, such as subscriptions or wholesale pricing, may involve additional work and costs. It’s worth discussing your longer-term plans before development begins so the website can be planned around what you need now and what you might add later.

Will I pay more if I need additional products beyond my ecommerce website quote?

Yes. If you need more product listings than your agreed website quote includes, you should expect an additional charge. The cost depends on the work required to prepare and upload those products, including descriptions, images, variants, specifications, and collection assignments. Before accepting a quote, confirm how many products are included, how variants are counted, and what additional listings will cost. Any extra charges should be agreed before the work is carried out.

What do I need to provide before my ecommerce website can accept payments?

You’ll normally need to set up an account with a suitable payment provider and supply the business, bank account, and identity information it requires. The provider may carry out verification checks before approving your account. Your website will also need its payment settings configured and the checkout process tested, including any relevant delivery and tax settings. Payment-provider approval and transaction charges are separate from the work involved in building the website.

Will my customers and their previous orders be kept if I move to a new ecommerce website?

Some customer information and order history can often be transferred, but this depends on the existing and new platforms, the available data, and the migration tools being used. Customers may need to reset passwords, while subscriptions, loyalty information, and other specialist records can require additional planning. Before agreeing to a migration, establish exactly which records can be transferred, how customer information will be handled securely, and what needs testing before the new website launches.

How long does it take to build an ecommerce website?

A straightforward ecommerce website can take several weeks to build, while larger or more complicated projects may take several months. The timetable depends on catalogue size, content preparation, design requirements, integrations, and whether information needs migrating from an existing store. Payment-provider verification, outstanding decisions, or incomplete product information can also delay launch. A website proposal should explain the expected timetable, key stages, and what the business needs to provide.

Do I need a separate website maintenance contract after launch?

No. A separate maintenance contract isn’t a universal requirement, although the website will still need appropriate ongoing management. Shopify includes hosting and core platform maintenance within its subscription, while WooCommerce websites require ongoing attention to WordPress, themes, plugins, backups, and hosting. These tasks can be managed internally or handled by a support provider. Check what support is included in the original website agreement and budget separately for essential platform charges, hosting where applicable, and payment-processing fees.

Planning an Ecommerce Website?

Set the budget around the store you actually need.

The right ecommerce website budget depends on the catalogue, platform, functionality, integrations, migration requirements, and how the store will be managed after launch. Clear project requirements make it easier to compare proposals and decide where the investment matters most.
