Choosing the right ecommerce platform is one of the most consequential decisions a UK brand will make. It determines your development costs, your conversion rate, your ability to scale, and how much of your time is spent fighting your technology rather than growing your business.
After twenty years of building, migrating, and scaling ecommerce stores across every major platform, I have formed clear views on which platforms serve UK brands best. This guide shares those views honestly, with real numbers and genuine trade-offs rather than marketing copy.
I will compare the six platforms that UK brands most commonly consider: Shopify, WooCommerce, Magento (Adobe Commerce), BigCommerce, Squarespace, and Wix. I will be fair about what each does well and where each falls short. But I will also be direct about which platform I believe gives UK brands the best chance of sustained ecommerce success.
What actually matters when choosing a platform
Before comparing individual platforms, it is worth establishing the criteria that matter most. Too many comparison articles focus on feature lists and ignore the factors that actually determine whether a platform works for a real business over multiple years.
Here are the eight criteria I evaluate, ranked by importance for UK ecommerce brands:
- Checkout conversion rate. The single most important metric. A 1% improvement in checkout conversion on a store doing £500k per year is worth £5,000 annually. Shopify's checkout, Shop Pay, converts at rates that other platforms struggle to match.
- Total cost of ownership (TCO). Not just the monthly fee. Include hosting, security, SSL, plugin/extension licensing, developer costs, maintenance, and the opportunity cost of downtime.
- Scalability. Can the platform grow with you from £50k to £5M in annual revenue without a painful migration? Does it handle peak traffic gracefully?
- Ecosystem and integrations. How many apps, plugins, and integrations are available? How well do they work? How quickly are new payment methods, shipping providers, and marketing tools supported?
- Developer availability. How easy is it to find competent developers for this platform in the UK? What do they charge?
- Performance (page speed). Managed hosting platforms typically outperform self-hosted solutions because they are optimised at the infrastructure level.
- UK-specific features. VAT handling, UK payment gateways, Royal Mail/DPD integrations, GDPR compliance tools, GBP as default currency, .co.uk domain support.
- Content management. How well does the platform handle blog content, landing pages, and rich media alongside products?
Shopify: the market leader for good reason
Shopify powers over 4.8 million stores worldwide and has become the default choice for direct-to-consumer brands. Its dominance is not accidental. Shopify has invested billions in building infrastructure that individual merchants could never replicate.
What Shopify does well
Checkout conversion. Shop Pay, Shopify's accelerated checkout, has one of the highest conversion rates in ecommerce. Shopify invests heavily in checkout optimisation, and every merchant benefits from those improvements automatically. You do not need to A/B test your own checkout — Shopify does it across millions of stores and pushes the winning variants to everyone.
Managed infrastructure. Shopify handles hosting, SSL certificates, security patches, PCI compliance, server scaling, and CDN distribution. You never think about server configuration, and your store stays online during traffic spikes. During events like Black Friday, Shopify processes billions in transactions without meaningful downtime.
App ecosystem. The Shopify App Store contains over 10,000 apps covering every conceivable ecommerce need. Need email marketing with Klaviyo? There is a native integration. Need product reviews, loyalty programmes, subscription management, or advanced analytics? There is an app for each, usually with multiple competing options.
Developer ecosystem. Shopify's developer community is enormous. Finding a qualified Shopify developer in the UK is straightforward compared to finding specialists for other platforms. This matters when you need ongoing development support or want to switch agencies.
Scalability. Shopify scales from a single-product store to an enterprise operation doing tens of millions. The transition from Shopify Basic to Shopify Plus does not require rebuilding your store — it is an upgrade, not a migration.
Where Shopify falls short
Content management. Shopify's built-in blogging and content management tools are functional but not sophisticated. If your business relies heavily on editorial content, you will find Shopify's CMS limited compared to WordPress.
Transaction fees. If you do not use Shopify Payments as your payment gateway, Shopify charges an additional transaction fee (0.5% to 2% depending on your plan). This is a meaningful cost for stores processing significant volume through third-party gateways.
Customisation ceiling. While Shopify is highly customisable through its Liquid templating language and APIs, there are boundaries you cannot cross without Shopify Plus. Checkout customisation, for example, requires the Plus tier.
Monthly cost. Shopify is not free. The ongoing subscription cost is higher than self-hosted alternatives where you only pay for hosting. However, when you factor in the total cost of ownership, Shopify is often cheaper.
WooCommerce: flexibility with a maintenance tax
WooCommerce is an open-source ecommerce plugin for WordPress. It powers approximately 36% of all online stores by installation count, making it the most widely used ecommerce solution by volume. However, installation count and active, well-maintained stores are different metrics.
What WooCommerce does well
Unlimited customisation. Because WooCommerce is open-source and runs on WordPress, there are virtually no limits to what you can build. Custom post types, complex content architectures, bespoke checkout flows, and unique product configurations are all possible with enough development time.
Content management. WordPress is the world's most mature content management system. If your business model combines ecommerce with significant editorial content — think a magazine that also sells products — WooCommerce on WordPress gives you the best CMS experience.
No platform fees. WooCommerce itself is free. You pay for hosting, a domain, and any premium plugins or extensions you need. There are no transaction fees imposed by the platform.
Full code ownership. You own every line of code and every database record. There is no platform dependency. You can host your store anywhere, modify anything, and migrate your data freely.
Where WooCommerce falls short
Security responsibility. You are responsible for security patches, WordPress core updates, PHP version compatibility, plugin conflicts, and server hardening. A single missed update can expose your store — and your customers' payment data — to vulnerabilities. This is not a theoretical risk; WooCommerce stores are regularly compromised due to outdated plugins or server misconfigurations.
Performance at scale. WooCommerce runs on traditional PHP/MySQL hosting. As your catalogue grows and traffic increases, performance degrades unless you invest in server optimisation, caching layers, and database tuning. Stores with 10,000+ products often struggle with slow admin panels and frontend performance issues.
Plugin dependency. WooCommerce's core functionality is limited. You need plugins for features that Shopify includes natively — discount codes, gift cards, abandoned cart recovery, multi-currency, and more. Each plugin adds complexity, potential conflicts, and ongoing licensing costs.
Checkout conversion. WooCommerce's default checkout is functional but not optimised for conversion. You can improve it with plugins, but you are essentially building and maintaining your own checkout experience rather than benefiting from a platform-level investment in checkout optimisation.

Magento (Adobe Commerce): enterprise power, enterprise cost
Magento — now branded as Adobe Commerce — is the enterprise-grade open-source ecommerce platform. It powers some of the world's largest ecommerce operations and offers capabilities that no other platform matches for complexity and scale.
What Magento does well
Complex catalogue management. Magento handles product catalogues with hundreds of thousands of SKUs, complex attribute sets, configurable products, and multi-store architectures better than any other platform. If you sell 50,000+ products with complex variants, Magento's catalogue management is genuinely superior.
Multi-store from a single installation. Magento natively supports multiple storefronts, each with different domains, designs, product catalogues, and pricing structures, all managed from a single admin panel. This is genuinely useful for brands operating multiple sub-brands or regional stores.
B2B capabilities. Adobe Commerce (the paid version) includes native B2B features: company accounts, custom catalogues, negotiated pricing, purchase orders, and approval workflows. These are enterprise-grade features that other platforms deliver only through third-party apps.
Where Magento falls short
Cost. Magento is expensive by every measure. Adobe Commerce licensing starts at approximately $22,000 per year. Hosting a Magento store with adequate performance costs £300-£1,500+ per month. A custom Magento build typically costs £50,000-£200,000+. Finding and retaining Magento developers is difficult and expensive — senior Magento developers in the UK command £65,000-£95,000+ in salary.
Complexity. Magento has a steep learning curve for both developers and store administrators. Simple tasks like adding a product attribute or configuring a promotion can require developer intervention. The admin interface, while powerful, is not intuitive.
Maintenance burden. Magento requires ongoing server maintenance, security patches (which often require developer deployment), performance monitoring, and regular upgrades. The total developer time consumed by maintenance alone can exceed 20-30 hours per month.
Declining ecosystem. Since Adobe's acquisition, the Magento community has contracted. Fewer new extensions are being developed, and many developers have migrated to Shopify. This trend is likely to continue.

BigCommerce: strong but underweight ecosystem
BigCommerce is the platform that should be Shopify's closest competitor. It offers a similar SaaS model with managed hosting, good built-in features, and competitive pricing. In many feature comparisons, BigCommerce matches or exceeds Shopify on paper.
What BigCommerce does well
Built-in features. BigCommerce includes more native features than Shopify without requiring apps. Multi-currency, product variants (up to 600 per product versus Shopify's 100), real-time shipping quotes, and advanced product filtering are all included in the core platform.
No transaction fees. BigCommerce does not charge additional transaction fees on any plan, regardless of which payment gateway you use. For stores processing significant volume through non-standard gateways, this is a genuine advantage.
B2B features. BigCommerce has invested heavily in B2B ecommerce, with customer-specific pricing, purchase orders, and quote management available on higher-tier plans.
Headless commerce. BigCommerce positions itself as a strong headless commerce option, with a robust API and partnerships with frontend frameworks. If you want to use a custom React or Next.js frontend, BigCommerce's API-first approach is competitive.
Where BigCommerce falls short
Ecosystem size. BigCommerce's app marketplace and developer ecosystem is significantly smaller than Shopify's. Where Shopify has dozens of competing apps for any given need, BigCommerce might have two or three. This limits choice and often means accepting a less polished solution.
UK developer availability. Finding a BigCommerce specialist in the UK is harder than finding a Shopify developer. The talent pool is smaller, which means higher costs and longer timelines for custom development.
Theme ecosystem. BigCommerce's theme selection is limited compared to Shopify's. The quality of available themes is generally lower, and there are fewer options for customisation without developer involvement.
Market momentum. BigCommerce has struggled to gain market share against Shopify. While the platform is technically competent, the network effects of Shopify's larger ecosystem create a widening gap.

Squarespace: design-first, commerce-second
Squarespace is primarily a website builder that has added ecommerce capabilities. It is popular with creative professionals, artists, and small brands that prioritise visual design above all else.
What Squarespace does well
Design quality. Squarespace templates are consistently beautiful. The design system is cohesive, and it is difficult to build an ugly site on Squarespace. For brands where visual presentation is paramount and the product catalogue is small, Squarespace delivers a premium look with minimal effort.
Simplicity. Squarespace is genuinely easy to use. Non-technical store owners can manage their products, update content, and process orders without developer assistance. The learning curve is the shortest of any platform in this comparison.
All-in-one pricing. Squarespace's pricing includes hosting, SSL, domain (for the first year), and basic analytics. There are no additional platform fees or transaction charges on the Commerce plans.
Where Squarespace falls short
Ecommerce depth. Squarespace's ecommerce features are shallow. Product variants are limited, discount functionality is basic, there is no native B2B support, and inventory management is rudimentary. If you need product bundles, complex pricing rules, or advanced product options, Squarespace cannot deliver.
App ecosystem. Squarespace has a very limited extension ecosystem. Where Shopify offers 10,000+ apps, Squarespace has perhaps a few hundred integrations, many of which are basic.
Scalability. Squarespace is suitable for stores with fewer than 200-500 products. Beyond that, performance degrades and the administrative experience becomes unwieldy. There is no enterprise tier.
Checkout conversion. Squarespace's checkout is functional but lacks the accelerated checkout options (like Shop Pay) that measurably increase conversion rates.
Our complete Shopify vs Squarespace comparison covers this in full detail.
Wix: the small business starter
Wix is a website builder that competes primarily on ease of use and entry-level pricing. Its ecommerce capabilities have improved significantly in recent years, but it remains a platform best suited to very small operations.
What Wix does well
Ease of use. Wix's drag-and-drop editor is intuitive for complete beginners. You can build a functional online store in a single afternoon without any technical knowledge.
Entry-level pricing. Wix's ecommerce plans start at competitive price points, making it accessible for side projects, hobby sellers, and very early-stage businesses testing product-market fit.
All-in-one approach. Wix handles domains, hosting, email, and basic marketing tools from a single dashboard. For a solopreneur managing everything themselves, this consolidation has value.
Where Wix falls short
Professional ecommerce. Wix is not built for serious ecommerce. Product management is limited, the checkout experience is basic, multi-currency support is restricted, and there is no equivalent of Shopify's Liquid templating for custom development. Advanced product options, customer accounts with order history, and sophisticated discount rules are either missing or limited.
Performance. Wix sites tend to be slower than equivalent Shopify stores. The platform's code output is heavier, and there are fewer options for performance optimisation.
Migration difficulty. Moving away from Wix is harder than leaving most other platforms. Product data export options are limited, and URL structures often cannot be replicated, making SEO-safe migration challenging.
Professional perception. Rightly or wrongly, Wix carries a perception of being an amateur platform. For brands selling premium products or targeting professional buyers, this perception can undermine credibility.
Side-by-side comparison table
Here is how the six platforms compare across the criteria that matter most for UK ecommerce brands:
| Criteria | Shopify | WooCommerce | Magento | BigCommerce | Squarespace | Wix |
|---|---|---|---|---|---|---|
| Monthly cost (starting) | ~£31/mo | Free (+ hosting) | Free / £17k+ (Adobe) | ~£24/mo | ~£24/mo | ~£19/mo |
| Hosting included | Yes | No | No | Yes | Yes | Yes |
| Checkout conversion | Excellent | Variable | Good | Good | Basic | Basic |
| App / extension ecosystem | 10,000+ | 50,000+ (WP plugins) | 3,000+ | 1,000+ | 200+ | 300+ |
| UK developer availability | High | Very high | Low (declining) | Low | Low | Low |
| Scalability ceiling | £100M+ | £5-10M (typical) | £100M+ | £50M+ | £500k | £250k |
| Security management | Managed | Your responsibility | Your responsibility | Managed | Managed | Managed |
| Multi-currency native | Yes (Markets) | Plugin required | Yes | Yes | Limited | Limited |
| Content management | Basic | Excellent | Good | Basic | Good | Good |
| B2B capabilities | Good (Plus) | Plugin required | Excellent | Good | None | None |
| Custom build cost (UK) | £10k-£50k | £8k-£40k | £50k-£200k+ | £15k-£50k | £2k-£8k | £1k-£5k |
Total cost of ownership: the honest numbers
The platform's monthly fee is often the smallest component of the total cost. Here is what a typical UK ecommerce brand doing £500k in annual revenue can expect to spend over three years on each platform:
| Cost component | Shopify | WooCommerce | Magento (OS) | BigCommerce |
|---|---|---|---|---|
| Platform fees (3 years) | £3,000 | £0 | £0 | £2,600 |
| Hosting (3 years) | Included | £3,600-£10,800 | £10,800-£54,000 | Included |
| Initial build | £15,000 | £15,000 | £60,000 | £20,000 |
| Apps/extensions (3 years) | £3,600 | £2,400 | £3,600 | £2,400 |
| Maintenance (3 years) | £5,400 | £14,400 | £36,000 | £7,200 |
| Security/compliance | Included | £1,800-£5,400 | £3,600-£10,800 | Included |
| Total (3 years) | £27,000 | £37,200-£48,600 | £114,000-£164,400 | £32,200 |
These figures are conservative estimates for a mid-market UK ecommerce brand. They exclude transaction fees, payment processing fees (which are similar across platforms), and the opportunity cost of developer time spent on maintenance rather than revenue-generating improvements.
The gap widens further at scale. A store doing £2M in annual revenue will see even larger differences in hosting costs, maintenance requirements, and the developer time needed to keep a self-hosted platform performing well.
The cheapest platform is not the one with the lowest monthly fee. It is the one that costs the least to own, maintain, and grow over three to five years. When you factor in everything, Shopify's total cost of ownership is competitive with platforms that appear cheaper on paper.
Who should use what
No platform is universally best. The right choice depends on your specific circumstances. Here is my honest recommendation for different types of UK businesses:
Choose Shopify if:
- You are a direct-to-consumer brand selling physical products
- You want to focus on growing your business rather than managing technology
- You plan to scale from under £100k to over £1M in annual revenue
- You value checkout conversion and want to benefit from platform-level optimisation
- You want access to the largest ecosystem of apps, themes, and developers
- You need a platform that handles SEO fundamentals well out of the box
Choose WooCommerce if:
- You have an existing WordPress site with significant content and organic traffic
- You have in-house developers comfortable with PHP and WordPress
- You need highly bespoke functionality that goes beyond what Shopify apps provide
- Your business model combines ecommerce with editorial content at equal priority
- You are comfortable managing your own hosting, security, and updates
Choose Magento (Adobe Commerce) if:
- You have a catalogue of 50,000+ products with complex attributes
- You need to run multiple storefronts from a single backend
- You have a budget of £100,000+ for initial build and £3,000+ per month for ongoing maintenance
- You have specific B2B requirements that justify the enterprise investment
- You already have a Magento team and the platform is working well for you
Choose BigCommerce if:
- You want a SaaS platform without transaction fees
- You need more built-in features than Shopify without relying on apps
- You are building a headless commerce implementation with a custom frontend
- Your product catalogue requires more than 100 variants per product
Choose Squarespace if:
- You are a creative professional selling a small number of products (under 100)
- Visual design is your absolute top priority and you manage the store yourself
- Your ecommerce revenue is under £100k per year and not the primary focus of the site
Choose Wix if:
- You are testing a product idea and need the fastest possible path to a live store
- Your budget is extremely limited and you have zero technical skills
- You are selling fewer than 50 products with no plans for significant growth
Why Shopify wins for UK brands
For the majority of UK ecommerce brands — those selling physical products, targeting consumers, and aiming to grow from five to seven figures in revenue — Shopify is the strongest platform choice in 2026. Here is why:
The checkout advantage is real and measurable. Shop Pay's accelerated checkout converts at rates consistently higher than standard checkouts. When your platform invests billions in checkout optimisation and you benefit automatically, that is a structural advantage your competitors on other platforms cannot replicate.
The ecosystem creates compounding value. Because Shopify has the largest market share among growth-stage DTC brands, app developers build for Shopify first. Payment providers integrate with Shopify first. Marketing platforms create Shopify-specific features first. This creates a virtuous cycle where the best tools are always available on Shopify before they reach other platforms.
Managed infrastructure eliminates the maintenance tax. Every hour your developer spends patching WordPress, tuning MySQL queries, or investigating Magento server errors is an hour not spent on revenue-generating improvements. Shopify eliminates this category of work entirely. For UK brands without large in-house technical teams, this is transformative.
The migration path is smooth. When your business grows, you can upgrade from Shopify Basic to Shopify Plus without rebuilding your store. You keep your theme, your data, your apps, and your URL structure. The transition from £50k to £5M in annual revenue happens on the same platform, with increasing capability at each tier.
UK-specific features are mature. Shopify handles VAT correctly for UK businesses, integrates natively with UK payment providers, supports Royal Mail and major UK carriers, and provides tools for UK-compliant web design including cookie consent and GDPR requirements.
If your ecommerce platform is holding your business back, the cost of staying is higher than the cost of migrating. We have helped brands move from every platform to Shopify, and in every case, the return on that migration investment was measured in months, not years.
Choosing an ecommerce platform is a business decision, not a technology decision. The best platform is the one that maximises your revenue, minimises your operational burden, and scales with your ambitions. For most UK brands in 2026, that platform is Shopify.

We will give you an honest assessment, even if Shopify is not the right fit — because the right recommendation is more valuable than a sale.
