Magento vs Shopify Plus for Growing UK Retailers

The Magento vs Shopify Plus debate has no universal right answer — but it has a right answer for your specific business. After building and managing both platforms for UK retailers across retail, manufacturing and B2B, here is our honest assessment of where each one wins.

The Short Answer

Shopify Plus is faster to launch, cheaper to run at moderate scale, and significantly easier to manage for businesses without a technical team. Magento (now Adobe Commerce) is more powerful for complex catalogues, multi-store architectures, B2B pricing models and businesses that need genuine platform ownership. The trade-off is total cost of ownership and the technical resource required to run it well.

When Shopify Plus Wins

• You are selling primarily B2C with a straightforward catalogue (under 10,000 SKUs, standard variants)
• You want predictable monthly costs without server management
• Speed to market is more important than deep customisation
• Your team is non-technical — Shopify's admin is genuinely easy to use
• You sell across D2C and want simple, native multi-channel (Shopify Markets for international)
• Your integrations are mainstream — most major ERPs and 3PLs have native Shopify connectors

Shopify Plus costs from $2,500/month (around £2,000). Add apps, integrations and a development agency, and total cost of ownership for a mid-size UK retailer typically runs £60,000–£120,000 per year all-in.

When Magento / Adobe Commerce Wins

• Complex B2B catalogues — customer-specific pricing, tiered discounts, quote requests, account hierarchies
• Large, complex product catalogues (100,000+ SKUs with complex attributes, configurable products, bundles)
• Multi-store architectures serving different brands, regions or languages from one platform
• Deep ERP integration that goes beyond standard order/stock sync
• You need to own the platform code and customise without Shopify's API constraints
• You are on Adobe Commerce Cloud and need enterprise SLA and support contracts

Total Cost of Ownership Compared

Shopify Plus fees are predictable but not cheap at scale. Revenue-based pricing applies above certain GMV thresholds. The real cost creep comes from app subscriptions: it is common for a Shopify Plus store to be paying £800–£2,000/month in third-party apps for features that come native in Magento.

Magento (self-hosted) has no licence fee for the open-source version, but requires cloud infrastructure, security patching, performance tuning and a technical team that understands the platform. Adobe Commerce (the enterprise licence) starts from around £30,000/year. A well-run Magento store typically costs £3,000–£8,000/month in total technical support, depending on size and activity.

Customisation and Developer Ecosystem

Shopify is deliberately constrained — the storefront framework (Liquid / Hydrogen) is powerful but operates within a defined boundary. If your requirement exceeds what Shopify's APIs expose, you are blocked. This matters less than it sounds for most retailers, but if you have genuinely complex checkout logic, Magento is more tractable.

Magento's developer pool in the UK is smaller than Shopify's and more expensive. Good Magento engineers are senior engineers — expect to pay accordingly. The flip side is that Magento knowledge is transferable; your store's codebase belongs to you and can be worked on by any Magento agency.

Migration Considerations

Migrating from Magento 1 / Magento 2 to Shopify Plus is a realistic option for many retailers, particularly if their current Magento store is over-customised and fragile. The catalogue, customers and orders migrate reasonably cleanly. The difficult parts are custom checkout flows, ERP integrations, and bespoke promotional rules that have no equivalent in Shopify's model.

Migrating from Shopify to Magento is less common but does happen when a business outgrows Shopify's customisation ceiling. It is a significant project — plan for 4–6 months minimum for a complex store.

Our Recommendation Framework

1. 1.If your catalogue is standard B2C and your team is not technical: start with Shopify Plus.
2. 2.If you have a complex B2B model, multi-store or deep ERP integration: evaluate Magento / Adobe Commerce seriously.
3. 3.If you are on an ageing Magento 1 or early Magento 2 store: modernise the Magento platform first, then decide whether to migrate or stay.
4. 4.If you are on Shopify and hitting customisation walls: document specifically what is blocked before assuming Magento is the answer — it may be solvable within Shopify.
5. 5.Whichever you choose: treat the platform as infrastructure and invest in the integrations, performance and automation that drive commercial results.
