The Problem With Picking an Ecommerce Platform
You’ve got products to sell, customers to serve, and approximately zero spare hours in the day. The last thing you need is to spend weeks researching ecommerce platforms only to pick the wrong one and have to start again six months later.
The good news: you don’t need to do all that research yourself. We’ve done it for you.
This guide cuts through the noise and compares the four most popular ecommerce platforms for UK small businesses in 2026 — Shopify, WooCommerce, Wix and Squarespace. We’ll look at real setup costs in pounds, how steep the learning curve is, and what transaction fees could cost you as your sales grow. By the end, you’ll know exactly which platform suits your situation.
What to Look For in an Ecommerce Platform as a UK Small Business
Before we dive into the platforms themselves, it’s worth being clear about what actually matters for a UK small business owner or sole trader.
Cost isn’t just the monthly subscription. Factor in transaction fees, payment processing, app costs, and whether you’ll need to pay a developer. A platform that looks cheap up front can quietly become expensive once you’re actually trading.
Ease of use matters more than it sounds. If you’re running the business yourself, you need to be able to update products, process orders and tweak your site without calling in a web designer every time.
UK-specific considerations include VAT handling, integration with HMRC’s Making Tax Digital (MTD) requirements, and whether your payment processor supports GBP as a primary currency without awkward conversion fees.
Scalability — will the platform still work for you if your business doubles in size next year?
With those criteria in mind, let’s look at each platform honestly.
Shopify — Best All-Round Ecommerce Platform for UK Sellers
Overview
Shopify is the closest thing the ecommerce world has to a gold standard for product-focused businesses. It was built specifically for selling online, and it shows. Everything — from inventory management to checkout flows to abandoned cart emails — is designed with a retailer in mind.
Setup Cost and Pricing
Shopify’s main plans in the UK on monthly billing:
- Starter: £5/month (buy buttons on social/existing sites only — no full storefront)
- Basic: £25/month
- Grow: £65/month
- Advanced: £344/month
Annual billing reduces these by around 25% (Basic drops to £19/month, Grow to £49/month, Advanced to £259/month), so it’s worth considering if you’re committing for the year.
Most small businesses will find the Basic plan sufficient to start. You can always upgrade as you grow.
Transaction Fees
This is where Shopify gets a bit complicated. If you use Shopify Payments (their own payment processor, powered by Stripe), there are no additional transaction fees — you just pay the standard card processing rates (2% + 25p per transaction on the Basic plan, dropping on higher tiers).
If you use a third-party payment gateway like PayPal or another processor, Shopify charges an additional transaction fee of 2% on the Basic plan, dropping to 1% and 0.5% on higher tiers. This can add up quickly, so most UK sellers stick with Shopify Payments.
Ease of Use
Shopify has a clean, well-designed dashboard that most non-technical users can get to grips with in a day or two. Adding products, setting up collections, and processing orders is genuinely straightforward. The theme editor is drag-and-drop, though it’s slightly less flexible than dedicated website builders like Wix.
UK Business Fit
Shopify integrates with most UK accounting software including Xero and QuickBooks, both of which support Making Tax Digital. VAT rates can be configured for UK businesses, and Shopify Payments supports GBP natively.
Best for: Product-based businesses with a reasonable volume of SKUs, anyone who wants a serious ecommerce setup from day one.
WooCommerce — Best for Flexibility (and Those Who Don’t Mind Getting Their Hands Dirty)
Overview
WooCommerce isn’t a standalone platform — it’s a free plugin for WordPress. If you already have a WordPress site, or you’re comfortable with WordPress, WooCommerce gives you an enormous amount of control over how your store looks and works. If you’ve never used WordPress, the learning curve is steeper than the other options here.
Setup Cost and Pricing
WooCommerce itself is free to download and install, which sounds brilliant until you account for everything else you actually need:
- WordPress hosting: typically £5–£20/month from providers like SiteGround or Kinsta
- Domain name: around £10–£15/year
- Premium theme: £40–£100 one-off (or free themes are available)
- Premium plugins: costs vary considerably — budget £100–£300/year for essentials like advanced shipping, bookings, or subscriptions
Total realistic annual cost for a small operation: £150–£600+, depending on your needs.
The trade-off for that complexity is genuine flexibility. You can make WooCommerce do almost anything.
Transaction Fees
WooCommerce itself doesn’t charge transaction fees — you pay whatever your payment gateway charges. Stripe and PayPal are the most popular choices for UK sellers, with Stripe typically around 1.5% + 20p for UK cards.
Ease of Use
Honest answer: WooCommerce is not beginner-friendly. If you’re confident with technology and don’t mind a bit of problem-solving, you’ll manage. If you want to focus entirely on your business and not on website maintenance, updates and occasional plugin conflicts, it will frustrate you.
That said, for developers or tech-savvy business owners, WooCommerce is incredibly powerful.
UK Business Fit
There are solid WooCommerce plugins for UK VAT handling (WooCommerce EU/UK VAT Compliance being a popular option). Integration with MTD-compatible accounting software is available but typically requires additional plugins or manual setup.
Best for: Developers, tech-confident sole traders, businesses that need a highly customised store and have either the skills or budget to build it properly.
Wix — Best for Beginners and Service-Based Sellers
Overview
Wix started life as a general website builder and added ecommerce functionality later. That heritage shows — the website-building side is excellent, but the ecommerce features are somewhat less sophisticated than Shopify’s. For small product ranges or service-based businesses adding a shop element, it works very well.
Setup Cost and Pricing
Wix’s plans (standard prices — promotional discounts are frequently available, so check the website before purchasing):
- Light: £9/month
- Core: £16/month
- Business: £25/month
- Business Elite: £119/month
These prices include hosting. There’s no separate charge for ecommerce functionality on Business plans and above.
Transaction Fees
Wix doesn’t charge its own transaction fees on top of payment processing costs. You’ll pay standard payment gateway rates through Wix Payments, Stripe, or PayPal. Wix Payments is available to UK businesses and processes GBP without issues.
Ease of Use
This is where Wix genuinely shines. The drag-and-drop editor is probably the most intuitive of all four platforms covered here. You can have a good-looking site live in an afternoon with no technical knowledge whatsoever. For someone who just wants to get online quickly without a steep learning curve, Wix is hard to beat.
UK Business Fit
Wix handles UK VAT reasonably well, and it integrates with a handful of accounting tools, though the integration ecosystem is less mature than Shopify’s. It’s a solid choice for sole traders selling a small range of physical products, digital downloads, or services.
Best for: Beginners, creative businesses, service providers with a small product range, anyone who values ease of use above all else.
Squarespace — Best for Visually-Led Brands
Overview
Squarespace has built a strong reputation for stunning templates and polished design. If your brand’s visual identity is central to how you sell — think independent clothing labels, photographers selling prints, or artisan food producers — Squarespace deserves serious consideration.
Setup Cost and Pricing
Squarespace’s plans (annual billing prices — monthly billing costs more, with up to 36% savings on annual):
- Basic: £12/month (annual) — £16/month (monthly)
- Core: £17/month (annual) — £24/month (monthly)
- Plus: £29/month (annual) — £36/month (monthly)
- Advanced: £79/month (annual) — £89/month (monthly)
All plans include hosting. Note that transaction fees apply on some lower-tier plans — make sure to check the current terms on Squarespace’s website before purchasing.
Transaction Fees
Squarespace charges no additional transaction fees on its Core plan and above. Standard payment processing rates through Stripe or PayPal apply.
Ease of Use
Squarespace sits between Wix and Shopify in terms of usability. The editor is less freeform than Wix — you work within structured sections rather than placing elements anywhere on the page — but many users find this actually produces better results because it’s harder to accidentally create something that looks messy. The product management side is clean and simple.
UK Business Fit
Squarespace handles UK VAT and supports GBP. It integrates with Xero, which is good news for MTD compliance. The platform is perhaps less focused on pure ecommerce than Shopify, but for businesses where the brand story matters as much as the transaction, it delivers.
Best for: Visually-led brands, creative businesses, small product ranges where presentation is everything.

Frequently Asked Questions
Which ecommerce platform is cheapest for a UK small business? On paper, WooCommerce costs the least because the software itself is free. In practice, once you factor in hosting, a theme and essential plugins, you’re likely spending £150–£600 per year. Wix’s Core plan at around £13/month is the cheapest all-in-one option if you want everything handled in one place. Always look beyond the headline monthly price.
Do I need to worry about Making Tax Digital when choosing an ecommerce platform? MTD for Income Tax came into effect from April 2026 for qualifying sole traders and landlords, with further phases expanding to lower income thresholds in 2027 and 2028. Your ecommerce platform doesn’t need to be MTD-compliant itself — but it should integrate cleanly with accounting software that is, such as Xero, QuickBooks or FreeAgent. Shopify and Squarespace both have strong Xero integrations. WooCommerce requires a plugin. Check HMRC’s website for the latest MTD thresholds.
Can I switch ecommerce platforms later if I change my mind? Yes, but it’s not painless. Moving products is manageable — most platforms allow CSV imports and exports. Migrating customer accounts, order history, and URL structures is trickier and can affect your search engine rankings if not handled carefully. It’s worth getting the decision right first time, but don’t let fear of switching paralyse you into inaction.
Is Shopify worth it for a very small business just starting out? Shopify’s Basic plan at £25/month (or £19/month on annual billing) is reasonable value even for a brand-new business, particularly if you’re planning to grow. The alternative is to start on Wix at a lower price point and migrate later — which is an option, but comes with the switching costs mentioned above. If you’re serious about ecommerce from day one, Shopify’s slightly higher entry price is usually worth it for the more robust selling tools.
Our Verdict: Which Is the Best Ecommerce Platform for UK Small Businesses in 2026?
There’s no single right answer, but there is a right answer for your situation:
- Choose Shopify if you’re building a product-focused business, want the best ecommerce feature set, and need a platform that can scale with you.
- Choose WooCommerce if you’re already on WordPress, have technical confidence, or need maximum customisation and have the budget to build it properly.
- Choose Wix if you’re just starting out, want the simplest possible setup, and don’t need advanced ecommerce features.
- Choose Squarespace if your brand’s visual presentation is central to your business and you’re selling a focused range of products.
For most UK small business owners reading this, Shopify is the safest bet. It’s not the cheapest, but it’s the most complete ecommerce solution, has excellent UK support, integrates well with HMRC-friendly accounting tools, and won’t limit you as you grow. The extra few pounds a month is genuinely worth it.
Whatever you choose, don’t overthink it. The best ecommerce platform is the one you’re actually using — and you can always refine your setup as your business develops.
Pricing and features correct at time of writing. Plans and capabilities are subject to change — always confirm current details on the provider’s website before purchasing.
