Shopify vs WooCommerce vs Custom: Choosing the Right E-commerce Platform in the UK

Key Takeaways

• Shopify is the fastest route to selling online, but monthly costs compound quickly as you add apps and scale
• WooCommerce gives you more control and lower long-term costs, but needs ongoing technical management
• Custom e-commerce makes sense when your products, pricing, or integrations don't fit standard platforms
• The 5-year total cost of ownership — not just the upfront build — is what actually matters when choosing

Shopify vs WooCommerce: which is the right e-commerce platform for your UK business? The short answer is that neither is universally better — the best choice depends on your products, technical confidence, budget and growth plans.

The Shopify vs WooCommerce debate has been running for years — and there is still no single right answer. What there is: a lot of bad advice, marketing hype from both platforms, and business owners choosing tools based on what they have heard rather than what actually suits their situation.

We have built e-commerce websites on Shopify, WooCommerce and fully custom stacks for clients ranging from a Cornwall food producer selling artisan hampers to a Kent-based industrial supplier with thousands of SKUs. Each project taught us something about where each platform thrives, where it struggles, and what the best ecommerce platform UK decision actually looks like in practice.

This is an honest comparison — not a sponsored post for either platform — covering costs, flexibility, UK-specific considerations and the scenarios where each option makes the most sense.

Key Takeaways

• Shopify vs WooCommerce is not a straight win for either — the best choice depends on your products, technical confidence, budget and growth plans
• WooCommerce powers approximately 36% of e-commerce sites globally (Source: BuiltWith, 2025), making it the most widely used e-commerce platform — not Shopify
• Shopify is easier to launch but more restrictive long-term; WooCommerce is more flexible but requires more technical management
• UK-specific requirements — VAT handling, UK-native payment processors, Royal Mail and DPD integrations — differ meaningfully between platforms
• Custom builds are the right choice for businesses with genuinely unique requirements, not a prestige option
• Ongoing website maintenance matters more on WooCommerce than Shopify — and matters on Shopify more than most people realise
• If you are unsure which direction to take, starting a project conversation is the best first step

Correcting a Common Misconception: Who Is Actually Winning?

Before comparing the platforms, let us address a persistent misconception. Shopify is often described as "the world's most popular e-commerce platform" in marketing materials and general press. The reality is more nuanced.

According to BuiltWith data (2025), WooCommerce powers approximately 36% of all e-commerce websites globally — making it the most widely deployed e-commerce platform in the world when measured by site count. Shopify holds a significant share of the premium hosted market and leads in terms of merchant revenue processed, but WooCommerce's installed base is larger.

This matters because it affects the size of the ecosystem you are buying into: the number of developers who know the platform, the availability of integrations, the volume of community support and the range of extensions available. WooCommerce's ecosystem is enormous precisely because of its market penetration.

Neither platform dominates all metrics. What the data shows clearly is that both are serious, mature platforms with large ecosystems — not one dominant and one niche.

Shopify: Best for Getting to Market Quickly

Shopify is a fully hosted e-commerce platform. You pay a monthly subscription, Shopify handles the infrastructure — hosting, security, PCI compliance, updates — and you focus on products and customers. The value proposition is simplicity and reliability.

What Shopify does well

The barrier to launch is genuinely low. A business owner with no technical background can go from sign-up to their first sale in a short time. The admin interface is clean and intuitive: adding products, processing orders, managing inventory, running discount codes — these are all straightforward. Shopify Payments (the built-in payment processor) integrates seamlessly and supports standard UK checkout flows.

Shopify's uptime and reliability are excellent. Because Shopify manages the infrastructure, you are not dealing with server outages, database crashes or hosting performance issues. For a business where downtime directly costs money, this reliability has real value.

The app ecosystem — while it comes at a cost — is extensive. There are well-maintained apps for email marketing (Klaviyo, Omnisend), customer reviews (Judge.me, Yotpo), upselling, subscriptions, loyalty programmes, abandoned cart recovery and a wide range of UK-specific integrations including Royal Mail Click & Drop, DPD and Parcelforce.

Where Shopify falls short

Customisation has a ceiling. Shopify's templating language (Liquid) is proprietary, which means meaningful custom development requires Shopify-specific expertise. You cannot simply hire any web developer — you need someone who knows Shopify's system. For standard shops, the available themes cover most needs. For businesses with non-standard requirements, hitting the ceiling of Shopify's customisation model is a real and frustrating experience.

Costs accumulate. The headline monthly subscription (Basic at £25/month, Shopify at £65/month, Advanced at £344/month at current UK pricing) is just the starting point. Most serious Shopify stores use multiple paid apps: email marketing, reviews, subscriptions, advanced reporting, return management. A realistic monthly cost for a properly equipped Shopify store is typically £100–£300/month in subscriptions alone. Over three years, that is a significant ongoing spend.

Transaction fees apply if you use a payment processor other than Shopify Payments. This is a meaningful constraint for UK businesses that want to use specific payment providers — SagePay/Opayo, for example — or that have existing merchant banking relationships they want to retain. The additional transaction fee (0.5–2% depending on your Shopify plan) adds up meaningfully at volume.

You do not own the platform. If Shopify changes pricing, terms, or removes a feature you depend on, your options are limited. Migrating away from Shopify is possible but involves friction — particularly for stores with large product catalogues and order histories.

UK-specific Shopify considerations

VAT handling: Shopify's built-in tax handling is adequate for most UK businesses selling to UK customers. For businesses with complex VAT requirements — selling digital goods to EU customers (OSS rules), handling VAT on mixed supplies, or operating across multiple tax jurisdictions — the native Shopify tools may need supplementing with a third-party app (TaxJar or Avalara).

Payment processors: Shopify Payments is available in the UK and supports major UK card brands. For businesses that specifically need Opayo (SagePay), Barclaycard or other UK legacy processors, these are available but incur transaction fees on top of gateway fees.

Shipping integrations: Royal Mail Click & Drop, DPD, Parcelforce and Hermes integrations are all available via the Shopify app store. These work well for standard shipping workflows. More complex fulfilment requirements (multi-warehouse, drop-shipping, click-and-collect from physical retail locations) may require more complex app setups.

Typical cost with professional design

Upfront design and build: £2,500–£5,000 Monthly subscription: £25–£344 Monthly apps: £50–£200+ Transaction fees (if not using Shopify Payments): 0.5–2% of revenue

Shopify is best for: businesses that want to launch quickly with minimal technical overhead, straightforward product ranges (under 500 products), businesses that value simplicity and managed reliability over maximum flexibility.

WooCommerce: Best for Flexibility and Long-Term Ownership

WooCommerce is a free, open-source e-commerce plugin for WordPress. It is installed on more e-commerce websites globally than any other platform (BuiltWith, 2025). The core plugin is free; you pay for hosting, premium extensions and your development work.

WooCommerce is the platform we know most deeply at Brambla. We have built WooCommerce shops for clients ranging from a small Devon artisan food producer selling a handful of products to a Kent-based B2B supplier managing trade pricing tiers, custom product configurations and integration with their existing inventory system. That breadth of experience informs what we say here.

What WooCommerce does well

You own everything. Your data, your shop, your codebase — none of it belongs to a third party. There is no platform subscription, no transaction fee from WooCommerce itself, and no risk that a pricing change by an external company materially affects your costs or options.

Flexibility is WooCommerce's defining characteristic. Because it runs on WordPress, the most widely used CMS in the world, you can combine your shop with a blog, resource library, membership area, booking system or any other functionality. The plugin ecosystem for WordPress is unmatched in depth. If you need complex product configurations — variable products, bundles, subscriptions, custom fields — WooCommerce handles these either natively or via well-maintained extensions.

For content-heavy shops — businesses where editorial content and product discovery are intertwined, like a food producer with recipes, a clothing brand with a lookbook or a tools retailer with buying guides — WooCommerce's native WordPress integration is a significant advantage. Managing content and products in the same CMS is genuinely easier than managing them in separate systems.

Developers are abundant. Because WordPress and WooCommerce are open-source and so widely used, the pool of developers who understand the platform is large. This tends to keep development costs lower and means you are never locked into a single agency relationship.

Where WooCommerce falls short

You are responsible for hosting, security, performance and updates. Shopify handles all of this for you. With WooCommerce, if your hosting is poor, your site will be slow. If you do not apply updates promptly, you accumulate security vulnerabilities. If two plugins conflict after an update, your shop may break. None of these are insurmountable problems, but they require either technical competence or a managed care plan to handle properly.

This is why every WooCommerce site we build is paired with a SiteCare plan. Managed hosting, regular updates tested before deployment, security monitoring and backups are not optional extras for a WooCommerce shop — they are what makes the platform reliably operate at the level Shopify provides out of the box.

The admin interface, while powerful, is more complex than Shopify's. Staff who need to manage orders, update products and process refunds can be trained on it, but the learning curve is steeper than Shopify's intentionally simplified dashboard.

Scaling to very high traffic volumes or very large product catalogues requires careful hosting configuration and database optimisation. A WooCommerce shop handling tens of thousands of orders per month is a different engineering challenge than a Shopify shop at the same volume — Shopify abstracts that complexity; WooCommerce exposes it.

UK-specific WooCommerce considerations

VAT handling: WooCommerce handles UK VAT well natively for standard use cases. For complex requirements — EU OSS, digital goods VAT, mixed supplies — the WooCommerce Tax plugin (free) combined with the correct configuration handles most scenarios. For high-volume sellers with complex tax requirements, Avalara's WooCommerce integration is the most robust option.

Payment processors: WooCommerce supports a wide range of UK payment processors natively or via official extensions. Stripe, PayPal, Opayo (SagePay), Barclaycard, WorldPay, GoCardless (for direct debit) and Klarna are all available. This is a meaningful advantage for UK businesses that have existing banking relationships or specific processor preferences — there are no transaction fees from WooCommerce for using third-party processors.

Shipping integrations: Royal Mail Click & Drop, DPD, Parcelforce, Hermes/Evri and a range of other UK carriers have WooCommerce integrations. Shipment tracking, label printing and return management are all achievable through WooCommerce's plugin ecosystem.

Typical cost with professional design

Upfront design and build: £3,500–£8,000 Managed hosting and maintenance (SiteCare): £65–£125/month Premium extensions: £0–£100/month depending on requirements WooCommerce transaction fees: none (payment processor fees apply as normal)

WooCommerce is best for: businesses that want full ownership and flexibility, shops with complex product configurations (variable products, bundles, subscriptions, trade pricing), businesses that already use WordPress, and shops where content and commerce are tightly integrated.

Custom Build: Best for Genuinely Unique Requirements

A custom e-commerce build means designing and developing a shop from the ground up — typically using a modern framework (Next.js with a headless commerce layer is our preferred stack for custom builds) rather than adapting a CMS plugin to a brief it was not designed for.

Custom builds are not a prestige option for businesses that want to spend more money. They are the right technical choice for a specific set of requirements. Recommending a custom build when WooCommerce would do the job is bad advice that wastes the client's money. What follows is an honest picture of when a custom build is genuinely warranted.

What custom builds do well

There are no inherited limitations. Every feature is built to your exact specification. The user experience can be designed entirely around your products, your customers and your sales process — not adapted from a theme template or constrained by a plugin's assumptions.

Performance is typically significantly better. Custom builds do not carry the weight of a CMS, plugin ecosystem and theme framework that was not built specifically for your use case. A next-generation e-commerce stack built on Next.js and a headless commerce backend can achieve Core Web Vital scores that are simply not achievable with a WordPress/WooCommerce stack on shared hosting.

Integration is unlimited. If you need your shop to communicate with an ERP system, a warehouse management platform, a bespoke wholesale pricing engine or a custom logistics provider, a custom build can be designed to integrate with anything that has an API — and without the constraint of finding a plugin that approximates what you need.

The result is genuinely unique. Your shop looks and works exactly as designed — nothing like a competitor's Shopify store running the same theme.

Where custom builds fall short

They cost more and take longer. This is simply true. A custom build requires detailed specification, more development hours and a longer testing process than adapting an existing platform. Budget expectations need to reflect this reality.

There is no plugin ecosystem. Every feature that a WooCommerce shop can achieve by installing a plugin requires custom development in a bespoke build. Reviews, subscriptions, advanced search, wishlist functionality — all of these need to be scoped and built. This is not a problem if the specification is clear and the budget is appropriate, but it is a common source of scope creep.

An ongoing developer relationship is required. You cannot simply install a plugin when you need a new feature. You need a development resource — internal or external — that understands your codebase and can implement changes. This is a meaningful ongoing commitment.

UK-specific custom build considerations

The advantage of a custom build for UK businesses is that UK-specific requirements — VAT calculation logic, UK payment processor APIs, carrier integrations, compliance with UK consumer law (right to returns, etc.) — can be built precisely rather than approximated through plugins. For businesses with genuinely complex UK-specific requirements, this precision is worth the investment.

Typical cost

Upfront design and build: £8,000–£25,000+ depending on complexity Ongoing hosting and maintenance: managed infrastructure costs, typically £150–£500/month Development for feature additions: billed per project or retained hours

Custom builds are best for: businesses with unique product types or complex pricing structures, high-volume shops that need maximum performance, businesses integrating e-commerce with existing business systems, and brands where the user experience is itself a competitive differentiator.

A Practical Comparison: Shopify vs WooCommerce vs Custom

Here is a straightforward comparison across the dimensions that matter most for UK businesses:

DIMENSION           | SHOPIFY          | WOOCOMMERCE       | CUSTOM BUILD
--------------------|------------------|-------------------|------------------
Ease of setup       | High             | Medium            | Low (most complex)
Customisation       | Limited          | High              | Unlimited
Ongoing costs       | Subscription + apps | Hosting + extensions | Hosting + dev time
Transaction fees    | Yes (non-Shopify Pay) | None from platform | None from platform
UK VAT handling     | Good (standard)  | Good (standard)   | Built to spec
UK payment options  | Good (with fees) | Excellent         | Excellent
Ownership           | Platform-owned   | Fully yours       | Fully yours
Performance ceiling | High (managed)   | Variable (hosting-dependent) | Highest
Maintenance burden  | Low (Shopify handles) | Medium-High   | High
Best for            | Simple, fast launch | Flexibility & content | Unique requirements

How to Decide: The Right Questions to Ask

Rather than starting with the platforms and working backwards, start with your requirements:

How many products, and how complex are they? Under 200 products with simple variations — Shopify is likely sufficient. 200+ products with complex configurations, bundled products or subscription options — WooCommerce gives you more control without paying for custom development. Thousands of products with bespoke pricing rules, ERP integration or custom fulfilment logic — consider a custom build.

What is your technical confidence and available resource? If you want to manage your store day-to-day with no technical involvement, Shopify is the lowest-friction option. WooCommerce requires WordPress familiarity and either technical competence or a managed maintenance plan. A custom build requires an ongoing developer relationship.

What does the long-term cost actually look like? Shopify's subscription and app costs compound over time — a store spending £150/month in platform and app costs is spending £1,800/year, every year, regardless of revenue. WooCommerce's costs are front-loaded in development and hosting, with lower ongoing platform costs. Over a 3–5 year horizon, WooCommerce is frequently the lower-total-cost option for a shop of meaningful size.

Do you need specific UK integrations? Check whether the processors, carriers and business systems you use have integrations available before committing to a platform. Most major UK requirements are covered by both Shopify and WooCommerce, but the fee structures differ significantly.

How important is brand differentiation through the user experience? If your checkout flow, product discovery experience or visual identity is itself part of what makes you different — if the experience of buying from you should feel distinct from any other shop — a custom build is the only way to achieve that. Both Shopify and WooCommerce can be customised meaningfully, but both carry inherited structural constraints.

Our Recommendation

We do not push a single platform. That is not in your interest — and clients who have been sold the "wrong" platform by an agency that only builds on one stack are among the most common projects we inherit.

Our e-commerce web design service covers Shopify, WooCommerce and custom builds. We will have a straightforward conversation about your products, your budget, your technical comfort and your growth plans — and recommend the platform that genuinely suits you, not the one we find most convenient to build on.

If you are already running a shop on one platform and wondering whether you should migrate, that is also a conversation worth having. Migrations are not always the right answer — sometimes optimising the current setup delivers better returns than rebuilding. We will tell you honestly which applies to your situation.

For businesses in Devon, Cornwall and beyond that are starting from scratch, our custom website service or an e-commerce-specific project brief is the best place to begin. We will scope the right solution for your specific needs — and build it to last.

Frequently Asked Questions

Is Shopify or WooCommerce better for a small UK business? Neither is universally better — it depends on your situation. Shopify is better for businesses that want simplicity, a fast launch and minimal technical management. WooCommerce is better for businesses that want full ownership, greater flexibility and lower long-term platform costs. For most UK small businesses with a standard product range and reasonable technical support, either platform can deliver an excellent result. The key is matching the platform to the business requirements, not the other way around.

What is the most popular e-commerce platform in the world? WooCommerce, by site count. According to BuiltWith (2025), WooCommerce powers approximately 36% of all e-commerce websites globally. Shopify has a large share of the premium hosted market and leads in gross merchandise value processed, but WooCommerce's installed base is larger. Both are mature, serious platforms with large developer ecosystems and strong track records.

Does WooCommerce handle UK VAT correctly? Yes, for the vast majority of UK businesses, WooCommerce handles VAT correctly out of the box. The WooCommerce Tax plugin and careful configuration cover standard UK VAT scenarios well. For complex cases — selling digital goods to EU consumers under the OSS scheme, mixed-supply VAT, or very high volume with complex jurisdictional requirements — additional configuration or a third-party tax integration (Avalara) may be needed. This applies equally to Shopify for the same complex scenarios.

Should I use Shopify Payments or a separate UK payment processor? If you are a straightforward UK business selling primarily to UK customers, Shopify Payments is a sensible choice — it integrates cleanly and avoids the additional transaction fee Shopify charges for external processors. If you have an existing banking relationship with a UK processor (Barclaycard, Worldpay, Opayo/SagePay), or if your business model requires GoCardless for direct debit billing, a WooCommerce build is more appropriate — WooCommerce does not charge transaction fees for external payment processors.

How much does a professional e-commerce website cost in the UK? A professionally designed Shopify store costs £2,500–£5,000 upfront, plus ongoing platform and app subscriptions. A WooCommerce build costs £3,500–£8,000 upfront, plus managed hosting and maintenance (from £65/month via our SiteCare plans). A custom e-commerce build starts from £8,000 for simpler requirements and scales significantly for complex integrations. The right investment depends entirely on your product complexity, your expected order volume and your growth ambitions.

Frequently Asked Questions

Which is cheaper, Shopify or WooCommerce?

Shopify costs £1,500–£5,000 to set up plus £29–£299/month in platform fees, plus transaction fees and app subscriptions. WooCommerce costs £3,500–£8,000 upfront but has lower monthly running costs (hosting from £65/month via our SiteCare plans). Over 5 years, WooCommerce is often cheaper for growing businesses — see our website cost guide for a full TCO breakdown.

When should I choose a custom e-commerce platform?

Custom builds make sense when you have complex pricing rules, unusual product configurations, deep integrations with existing business systems (ERP, warehouse management), or when Shopify and WooCommerce's standard features genuinely can't do what you need. For most UK SMEs selling fewer than 500 products, Shopify or WooCommerce is the right starting point.

Can I move from Shopify to WooCommerce later?

Yes, but it's not trivial. Product data, customer accounts, order history, and URL structures all need migrating. The cost is typically £2,000–£5,000 depending on catalogue size and complexity. It's worth choosing the right platform upfront rather than planning to migrate later.
