The Core Philosophical Difference

WooCommerce and Shopify represent fundamentally different philosophies about how software should work. WooCommerce is an open-source plugin that turns any WordPress site into a store — you own everything, control everything, and are responsible for everything. Shopify is a SaaS platform — you rent a powerful, managed service with defined limits and a monthly fee.

Neither is objectively better. The right choice depends on your technical capability, budget structure, product complexity, and long-term growth plans.

Market reality: Shopify powers ~4.4M online stores globally. WooCommerce powers ~6.5M. Both are viable at scale — Gymshark launched on Shopify Plus and reached £500M revenue. New Balance runs WooCommerce stores. The platform doesn't determine success.

Cost: The Full Picture

The cost comparison is more nuanced than the surface-level monthly fee comparison suggests.

Shopify total cost of ownership:

  • Basic: $39/month · Shopify: $105/month · Advanced: $399/month · Plus: $2,300/month
  • Transaction fees: 0.5–2% on non-Shopify Payments (waived with Shopify Payments)
  • Apps: most functionality beyond basics requires paid apps — $200–$600/month is typical for a mature store
  • Theme: $180–$350 one-time for premium themes
  • Typical SME annual cost: £8,000–£15,000 (platform + apps)

WooCommerce total cost of ownership:

  • Plugin: free. Hosting: £50–£300/month depending on scale.
  • Extensions: many are free; premium extensions £100–£500/year each
  • Developer cost: higher — WooCommerce requires ongoing developer involvement for maintenance, updates, and customisation
  • Typical SME annual cost: £5,000–£20,000 (hosting + extensions + developer time)
The WooCommerce hidden cost: Developer time for updates, security patches, and custom functionality is the largest hidden cost. Budget £3,000–£8,000/year for ongoing WooCommerce development support on a growing store.

Flexibility and Customisation

WooCommerce wins here, clearly. Because it's open-source and built on WordPress, there are no limits to what you can build. You have direct database access, can modify core templates, write custom plugins, and integrate with any system via REST API or custom code.

Shopify's liquid templates and limited API access create a ceiling on customisation — particularly in the checkout flow (locked to Shopify Plus users for checkout customisation) and on pages outside the standard store structure.

WooCommerce customisation wins: Custom product configurators, complex subscription logic, unusual B2B workflows, custom checkout flows, integration with legacy ERP systems, multi-vendor marketplaces.

Shopify customisation wins: Standard e-commerce flows, app-based customisation within Shopify's architecture, quick time-to-market without bespoke development.

Performance and Scalability

Shopify wins on raw performance and scalability. Shopify's infrastructure is managed, auto-scaled, and battle-tested on Black Friday with millions of concurrent users. You never need to worry about servers falling over during a traffic spike.

WooCommerce performance is entirely dependent on your hosting, caching configuration, and database optimisation. A badly-configured WooCommerce store can fall over with 500 concurrent visitors. A well-optimised one on Kinsta or WP Engine handles significant traffic without issues.

For most SMEs under £5M revenue, both platforms perform adequately with correct setup. Above £10M, Shopify Plus's managed infrastructure starts to show a meaningful reliability advantage over self-managed WooCommerce hosting.

Our Recommendation Framework

Choose Shopify if: You want a fully-managed platform, your team doesn't have in-house development capability, you need fast time-to-market, or your e-commerce flows are standard (product → cart → checkout).

Choose WooCommerce if: You need deep customisation that Shopify can't deliver, you're already on WordPress with significant content investment, you want to avoid Shopify's transaction fees, or you need multi-vendor marketplace functionality.

Choose Shopify Plus if: You're above £3M annual revenue, need custom checkout flows, require dedicated account management, or want the peace of mind of an enterprise-grade managed platform.

Migration considerations: Migrating between platforms is painful — product data, order history, customer accounts, and SEO URLs all need careful handling. Choose your platform for the next 3–5 years, not just today's requirements.
