At the enterprise level, the Shopify Plus versus Magento 2 (now Adobe Commerce) decision is one of the most consequential technology choices an ecommerce brand will make. Both platforms can support multi-million-pound operations. Both have proven track records at scale. But they represent fundamentally different philosophies about how enterprise ecommerce should work.
Shopify Plus is managed enterprise SaaS. You pay a monthly fee and Shopify handles the infrastructure, security, performance, and platform updates. You focus on customising the storefront, building customer experiences, and growing revenue.
Magento 2 (Adobe Commerce) is open-source enterprise software that you deploy on your own infrastructure. You have complete control over every aspect of the platform. You also bear complete responsibility for hosting, security, performance, and maintenance.
I have worked with brands running both platforms at significant scale. This comparison covers the areas that matter most at the enterprise level: total cost of ownership, customisation, performance, security, and the operational reality of running each platform.
The enterprise landscape
The enterprise ecommerce market has shifted dramatically over the past five years. Historically, Magento was the default choice for enterprise ecommerce — its open-source flexibility and deep customisation made it the platform of choice for complex requirements. Shopify Plus was seen as suitable only for simpler DTC brands.
That perception has changed substantially. Shopify Plus now powers major enterprise brands across fashion, beauty, food, electronics, and B2B. Magento's market share has declined as Adobe has repositioned the platform and many brands have migrated to SaaS alternatives.
Both platforms remain viable at the enterprise level, but the decision criteria have evolved. Total cost of ownership and operational complexity have become as important as raw feature depth. See our Shopify vs WooCommerce comparison for a similar analysis at the mid-market level.
Total cost of ownership
This is the most important comparison point for enterprise buyers, and it is where Shopify Plus has its most compelling advantage.
| Cost component | Shopify Plus (per year) | Adobe Commerce (per year) |
|---|---|---|
| Platform licence | £21,000-£42,000 | £18,000-£120,000+ |
| Hosting and infrastructure | Included | £12,000-£60,000+ |
| Security and PCI compliance | Included | £6,000-£24,000 |
| Development team | £36,000-£96,000 | £120,000-£300,000+ |
| Apps and extensions | £6,000-£18,000 | £12,000-£36,000 |
| Maintenance and updates | Included | £24,000-£72,000 |
| Annual total | £63,000-£156,000 | £192,000-£612,000+ |
The development team cost is the largest differentiator. Magento 2 requires specialist PHP developers with Magento-specific expertise — a rare and expensive combination. Shopify Plus developers work with Liquid, JavaScript, and the Shopify APIs, which are more widely understood.
Maintenance costs for Magento are particularly high. Major version upgrades, security patches, extension compatibility testing, and performance tuning require significant ongoing developer investment. On Shopify Plus, platform updates are automatic and backwards-compatible. For a deeper look at Shopify Plus pricing specifically, see our Shopify Plus pricing transparency guide.
Customisation depth
This is Magento's strongest advantage. Because you have access to the entire codebase, there are no platform-imposed limitations on what you can build.
Magento 2 customisation
- Complete access to the PHP codebase, database, and server environment
- Custom modules can modify any aspect of platform behaviour
- Checkout can be completely rebuilt from scratch
- Complex product types and pricing logic with no constraints
- Custom API endpoints and integrations at any level
- Multi-store with shared or separate databases
Shopify Plus customisation
- Checkout Extensions and Shopify Functions for checkout customisation
- Shopify Flow for backend automation
- Custom apps via the Shopify API
- Liquid templating for storefront customisation
- Script Editor for pricing, shipping, and payment customisation
- Metafields and Metaobjects for custom data
Shopify Plus has narrowed the customisation gap significantly with Checkout Extensions, Shopify Functions, and the expanding API. However, for truly bespoke business logic that cannot be expressed through Shopify's extension points, Magento's open-source codebase offers more flexibility. See our guide on optimising Shopify stores for what is achievable within the platform.
Performance and infrastructure
Shopify Plus runs on Shopify's global infrastructure, which handles over $7 billion in annual GMV during Black Friday/Cyber Monday alone. Performance scaling is automatic. There is no capacity planning, no load testing against infrastructure limits, and no server provisioning for traffic spikes.
Magento 2 performance depends entirely on your hosting infrastructure. A well-tuned Magento 2 installation on premium cloud hosting can perform exceptionally well. However, achieving and maintaining that performance requires dedicated DevOps expertise, continuous monitoring, and proactive optimisation. Common performance issues include slow database queries, inefficient third-party extensions, and inadequate caching configuration.
The operational reality is stark: Shopify Plus brands do not have a DevOps team managing infrastructure. Magento brands typically need at least one full-time DevOps engineer, often more for high-traffic stores.
Security and compliance
Shopify Plus provides PCI DSS Level 1 compliance automatically, handles all security patching, manages SSL certificates, and protects against DDoS attacks at the infrastructure level. Security incidents at the platform level are extremely rare.
Magento 2 has had several significant security vulnerabilities over the years, requiring emergency patches. The Magecart attacks specifically targeted Magento stores at scale. While Adobe has improved security processes, the responsibility for applying patches, maintaining PCI compliance, and managing server security falls entirely on the merchant and their development team.
For enterprise brands handling significant volumes of customer data and payment information, the security overhead of managing a Magento installation is substantial and non-negotiable.
Checkout and conversion
Shopify Plus's checkout, enhanced with Shop Pay, is one of the highest-converting in ecommerce. Checkout Extensions allow enterprise-level customisation while maintaining the platform's optimised checkout flow. Every Shopify Plus merchant benefits from continuous checkout optimisation that Shopify conducts at scale.
Magento's checkout can be completely customised, which is both an advantage and a risk. Custom checkout implementations can introduce conversion-reducing friction if not properly tested and optimised. However, for brands with checkout requirements that are genuinely unique — complex B2B approval workflows, for example — Magento's fully customisable checkout is necessary.
B2B capabilities
Magento has historically been stronger in B2B with its native B2B module offering: company accounts with hierarchical structures, requisition lists, negotiable quotes, purchase orders, payment on account, and company credit limits. These features are mature and well-integrated.
Shopify Plus has rapidly expanded its B2B capabilities with wholesale pricing, company profiles, payment terms, quantity rules, and B2B-specific checkout experiences. While not as mature as Magento's B2B module, Shopify Plus B2B covers the needs of most B2B-DTC hybrid businesses and is improving with each platform update.
Multi-store and internationalisation
Magento's multi-store architecture allows multiple storefronts, currencies, languages, and catalogues from a single installation. This is native functionality that has been refined over many years. For brands requiring truly independent stores with shared backend operations, Magento's multi-store is powerful.
Shopify Plus offers Shopify Markets for international selling and allows up to 10 expansion stores. While not as flexible as Magento's native multi-store, Shopify Markets handles most internationalisation needs including multi-currency, multi-language, and market-specific pricing. For most brands, this is sufficient. For complex multi-brand, multi-region operations, Magento may still have an edge.
Ecosystem and integrations
Shopify's app and partner ecosystem is significantly larger than Magento's. Enterprise integrations with ERP systems, PIMs, CRMs, and marketing platforms are well-supported through both native apps and the Shopify API. The ecosystem is actively growing, with new integrations launching regularly.
Magento has a mature extension marketplace and strong integration capabilities through its API. However, extension quality varies significantly, and compatibility issues between extensions are common. The Magento ecosystem has contracted as some developers have shifted focus to Shopify.
For enterprise integrations specifically — connecting with SAP, NetSuite, Salesforce, or custom ERP systems — both platforms are capable. Shopify Plus often achieves these integrations faster and at lower cost due to the simpler technical architecture. For more on Shopify's development capabilities, see our services page.
Developer talent
Magento 2 developers are expensive and increasingly rare. The platform's complexity requires deep expertise in PHP, the Magento framework, and server management. Adobe's certification programme is rigorous, and certified developers command premium rates. Finding qualified Magento developers in the UK is becoming more difficult as the talent pool shrinks.
Shopify Plus developers are more widely available and typically less expensive. The platform's simpler technical architecture means a broader range of developers can work with it effectively. The Shopify Partner ecosystem has thousands of UK-based agencies and freelancers.
Migration considerations
Migrating from Magento 2 to Shopify Plus is a significant undertaking but increasingly common. Key considerations include: catalogues and product data migration, custom functionality replacement, URL mapping for SEO preservation, integration re-establishment, and team retraining.
The most challenging aspect is typically replacing custom Magento modules with Shopify Plus equivalents. Many custom modules can be replaced with Shopify apps or Shopify Functions, but some require custom app development. Our guide on migrating from Magento to Shopify covers the process in detail.
The verdict
For most enterprise UK ecommerce brands, Shopify Plus is the better choice. Its lower total cost of ownership, automatic scaling, managed security, and growing customisation capabilities make it the more efficient platform for most enterprise use cases.
