Choosing between Shopify, WooCommerce and custom e-commerce for your UK business in 2026 is not just about features — it is about finding the platform that will not drain your budget or leave you stranded when things go wrong. With UK online retail continuing to grow, the stakes have never been higher.
The problem is that most platform comparisons ignore the real costs and complexities UK businesses face. Transaction fees that eat into margins, VAT complications that platforms do not handle cleanly, and support teams that do not understand British business needs.
This guide gives you the straight answers — no marketing fluff, no affiliate bias. If reading about platform options makes you want to close the tab, SoftwareYeah offers e-commerce development as a core service and can just handle the decision for you.

How much does each platform really cost UK businesses?
Let's cut through the marketing and look at real costs. These figures include VAT and the hidden fees most comparisons ignore.
Shopify true costs (including VAT)
Basic Shopify: around £34.80/month (inc. VAT) plus 2.9% + 30p per transaction. For a business processing £10,000/month, you are looking at roughly £325 in platform fees alone.
Shopify (mid tier): around £95/month (inc. VAT) plus 2.6% + 30p per transaction. Same £10,000 business pays around £355 monthly.
Advanced Shopify: around £358/month (inc. VAT) plus 2.4% + 30p per transaction. Monthly total approaches £629 for our example business.
The exact figures change periodically — check Shopify's current UK pricing before committing — but the pattern holds: Shopify's monthly cost is small, its transaction fees are what you really pay.
WooCommerce hidden costs
WooCommerce itself is free, but here is what UK businesses actually spend to run one properly:
- Hosting: £20–£150/month for proper e-commerce hosting
- SSL certificate: £50–£200/year (sometimes included with hosting)
- Premium plugins: £200–£800/year for payment gateways, SEO, backups, security
- Maintenance and security: £50–£300/month, or 5–10 hours of your time every week
- Payment processing: typically 2.9% + 30p with Stripe
Realistic monthly cost for a properly configured WooCommerce store: £120–£450, not including your own time investment.
Custom e-commerce development
UK custom e-commerce development typically costs £5,000–£25,000 upfront. Monthly running costs are often lower — just hosting (£50–£200) and maintenance (£100–£500). No platform transaction fees means better margins long term. For a broader look at bespoke software pricing beyond e-commerce, see our bespoke software cost guide.
For businesses processing more than £25,000/month, custom solutions often become more cost-effective within 12–24 months. For a guide to how these numbers compare to a regular website build, see our companion post on UK website costs for small businesses.
What makes Shopify different from WooCommerce?
The Shopify vs WooCommerce debate comes down to control versus convenience. Understanding these fundamental differences saves months of regret.
Shopify: the all-in-one approach
Shopify handles everything — hosting, security updates, payment processing, even customer support. You get a complete package with minimal technical knowledge required. Updates happen automatically, and if something breaks, it is their responsibility to fix it.
The trade-off is limited customisation and ongoing monthly fees regardless of your sales volume. You are also locked into their ecosystem — moving away later means rebuilding from scratch. Our guide to AI website builders vs custom development covers this lock-in problem in more detail.
WooCommerce: the WordPress solution
WooCommerce gives you complete control over your store's functionality and appearance. As a WordPress plugin, it integrates seamlessly with existing WordPress sites and offers thousands of extensions.
However, you are responsible for hosting, security, updates, and troubleshooting. One poorly coded plugin can crash your entire store. WooCommerce is one of the most widely used e-commerce platforms, but that popularity also makes it a target for attacks.
Key technical differences
- Setup time: Shopify — 2–4 hours for basic store; WooCommerce — 2–4 weeks for proper configuration
- Customisation: Shopify — limited to themes and apps; WooCommerce — unlimited with developer knowledge
- Support: Shopify — 24/7 included; WooCommerce — community forums or paid developers
- Performance: Shopify — optimised automatically; WooCommerce — depends on your hosting and configuration
Which platform works best for small UK retailers?
Your answer depends on three crucial factors: technical comfort level, growth trajectory, and cash flow management.
Choose Shopify if you are...
- New to e-commerce and want to start selling quickly
- Processing under £15,000 monthly (transaction fees become painful above this)
- Selling straightforward products without complex variations
- Someone who prefers predictable monthly costs over surprise technical issues
- Without reliable technical support or a web developer
Shopify works well for retailers who want to focus on selling rather than managing technology. It powers brands at every scale, from single-founder stores to massive operations.
Choose WooCommerce if you are...
- Already comfortable with WordPress or have a developer relationship
- Selling complex products requiring extensive customisation
- Processing higher volumes where transaction fees become significant
- Planning serious content marketing integration alongside your e-commerce
- Requiring specific integrations not available on Shopify
WooCommerce suits businesses with technical resources who need flexibility over convenience.
Red flags for either platform
Neither platform suits businesses requiring:
- Complex B2B pricing structures with custom rates per customer
- Multi-vendor marketplace functionality
- Extensive ERP or warehouse management system integration
- Unique checkout processes or payment methods
These scenarios typically need custom development to work properly.
Why consider custom e-commerce development instead?
Custom solutions often get overlooked in platform comparisons despite offering significant advantages for established UK retailers.
Platform limitations hit growing businesses hard
Both Shopify and WooCommerce impose restrictions that become costly as you scale. Shopify's transaction fees can exceed £3,000 monthly for a £100,000/month business. WooCommerce's plugin dependency creates stability issues under high traffic.
Custom development eliminates these constraints. You own the code, pay no platform transaction fees, and modify functionality without waiting for a plugin update.
UK-specific requirements
British businesses often need features that platforms handle poorly:
- Complex VAT calculations for different product categories
- Integration with UK-specific logistics providers (Royal Mail, DPD, Parcelforce)
- GDPR compliance beyond basic cookie banners
- B2B trade accounts with custom pricing structures
- Multi-location inventory management
A UK-based development approach means these requirements are built in rather than bolted on through awkward workarounds. If GDPR is a concern — and for UK retailers, it always is — see our GDPR compliant software checklist for what to watch out for.
Long-term cost benefits
While custom development has higher upfront costs, the maths often favour bespoke solutions:
- No monthly platform fees (savings: £420–£4,300+ annually depending on tier)
- No platform transaction fees (savings: 2.4–2.9% of revenue)
- Lower hosting costs with optimised infrastructure
- Reduced plugin and app dependencies
Custom e-commerce typically reaches cost parity with platforms within 12–24 months for businesses processing over £20,000/month.
How do these platforms compare on key features?
This table shows real-world capabilities rather than marketing promises:
| Feature | Shopify | WooCommerce | Custom Development |
|---|---|---|---|
| Setup time | 2–4 hours | 2–4 weeks | 6–16 weeks |
| Monthly costs | £35–£360 + fees | £120–£450 | £50–£500 |
| Transaction fees | 2.4–2.9% + 30p | Payment gateway rates only | Payment gateway rates only |
| Customisation | Theme + app limitations | Extensive with plugins | Unlimited |
| SEO capabilities | Good built-in | Excellent with plugins | Best when properly built |
| Mobile responsiveness | Automatic | Theme-dependent | Custom-optimised |
| Support | 24/7 included | Community forums | Your developer |
| Ownership | Platform controls | You own content | Complete ownership |
Payment processing reality check
All platforms integrate with major UK payment providers like Stripe, PayPal, and Worldpay. The difference lies in flexibility and fees.
Shopify restricts you to their payment partners unless you pay additional transaction fees on top. WooCommerce and custom solutions let you negotiate directly with payment processors for better rates.
Stripe's standard UK rates are around 2.9% + 30p at the time of writing, but high-volume merchants can negotiate lower rates more easily with custom solutions.
Inventory management differences
Stock control becomes critical as you grow. Shopify handles basic inventory well but struggles with complex variations or multi-location stock. WooCommerce requires plugins for advanced inventory features, creating potential conflict issues.
Custom solutions integrate seamlessly with existing inventory systems and can handle unlimited product variations without performance degradation.
What are the common migration gotchas?
When considering an e-commerce platform change, understanding migration complexities helps avoid costly mistakes.
Shopify to WooCommerce migration issues
- Product data translation: Shopify's product structure does not translate perfectly
- Customer account problems: password hashes cannot be migrated, forcing customer resets
- SEO disruption: URL structures differ, requiring careful 301 redirect mapping
- App dependency: Shopify apps have no WooCommerce equivalent, requiring new solutions
WooCommerce to Shopify challenges
- Customisation loss: complex WooCommerce modifications will not work on Shopify
- Plugin functionality: many WooCommerce plugins have no Shopify app alternative
- Content migration: blog posts and pages often require manual recreation
- Payment gateway changes: may require new merchant accounts
Migration timeline reality
Platform migrations typically take 4–12 weeks for complex stores. Budget for temporary revenue disruption and additional development costs.
UK VAT requirements add complexity to any migration, requiring careful attention to tax calculation preservation.
Which should you choose for your UK business?
The "Shopify vs WooCommerce vs custom" question depends entirely on your specific situation. Here is a simple recommendation framework:
Choose Shopify when
- Monthly sales are under £15,000
- You have limited technical resources
- You have a standard product catalogue
- Quick market entry is the priority
- Predictable monthly costs matter more than flexibility
Choose WooCommerce when
- You already have WordPress expertise available
- Your products have complex requirements
- Content marketing integration is a priority
- You have higher transaction volumes where 2.9% hurts
- You want customisation control
Choose custom development when
- Monthly sales exceed £20,000
- You have unique business requirements a platform cannot support
- Platform limitations are affecting growth
- Long-term cost optimisation is a priority
- Complete control is non-negotiable
The decision does not need to be permanent. Many successful UK retailers start with Shopify for speed to market, then migrate to custom solutions once they scale past the point where transaction fees start hurting.
Frequently Asked Questions
Which is cheaper — Shopify or WooCommerce?
It depends on your sales volume. Shopify has lower hidden costs but higher transaction fees. WooCommerce is "free" but hosting, plugins and maintenance add up. For under £10k/month in sales, they end up similar. Above that, WooCommerce typically wins on total cost — if you can manage the technical side.
Can I switch from Shopify to custom development later?
Yes, and many UK retailers do exactly this once they outgrow Shopify's limitations. Migration takes 4–12 weeks depending on complexity. The main challenges are URL redirects (to preserve SEO), customer accounts, and historical order data.
Is WooCommerce safe for UK businesses handling GDPR data?
WooCommerce can be GDPR compliant with the right configuration and plugins, but it requires active management. Your hosting, security updates, plugin choices and cookie consent all need attention. It's not automatic the way Shopify's compliance features are.
How much should I budget for a custom e-commerce build in the UK?
Realistic range is £5,000–£25,000 upfront for a custom e-commerce build, depending on complexity. Simple stores with standard features start at £5k. Complex builds with integrations, B2B pricing, or advanced inventory can reach £25k or more. Most UK SMEs land somewhere in the middle.
Do I need a separate payment processor with custom e-commerce?
Yes — custom e-commerce stores integrate with payment processors like Stripe, Worldpay, or PayPal. The advantage is you negotiate directly with the processor and avoid platform markups. This is one of the biggest long-term savings of custom development.
Can SoftwareYeah build custom e-commerce for UK retailers?
