If you are evaluating enterprise ecommerce platforms in 2026, you have almost certainly narrowed your list to Shopify Plus and BigCommerce Enterprise. They are the two dominant hosted platforms for mid-market and growing ecommerce businesses, and they compete directly for the same customers.

The comparison is not as straightforward as most review articles suggest. Both platforms are competent. Both will handle a catalogue of several thousand SKUs, process millions in annual revenue, and integrate with the tools your operations team depends on. The differences are in philosophy, flexibility, and where each platform makes trade-offs — and which trade-offs matter depends entirely on your specific business.

This guide tries to be more useful than a feature checklist. We will cover where each platform genuinely excels, where it falls short, and which types of businesses tend to be happier on each.

The Fundamental Difference

Before comparing features, it helps to understand the design philosophy behind each platform.

Shopify Plus optimises for speed to market and operational simplicity. Its approach is opinionated — there is a “Shopify way” of doing things, and the platform works best when you follow it. The trade-off is reduced flexibility in exchange for a platform that handles most operational complexity for you.

BigCommerce Enterprise optimises for native flexibility. It offers more built-in features out of the box and more control over how the storefront works without requiring apps or custom development. The trade-off is that this flexibility creates more decisions to make and more surface area to manage.

Neither philosophy is wrong. The question is which matches how your business operates.

Pricing and Total Cost of Ownership

Platform Fees

Shopify Plus starts at $2,300/month (approximately £1,850/month) on a three-year term, scaling with GMV. The pricing model is percentage-based above a threshold — once you cross roughly $800K/month in GMV, you pay the greater of $2,300 or a percentage of revenue. For more detail on how costs scale, see our Shopify Plus pricing guide.

BigCommerce Enterprise does not publish pricing — it is quote-based and negotiated. From what we have seen working with clients, comparable plans start in a similar range to Shopify Plus but the pricing structure is more flexible, often based on a flat annual contract rather than a GMV-based model.

Transaction Fees

This is where meaningful cost differences emerge.

Shopify Plus waives transaction fees only if you use Shopify Payments. If you use a third-party payment gateway, Shopify charges 0.15%-0.30% on top of whatever your payment processor charges. For a business doing £5M/year, that is £7,500-£15,000 in additional fees.

BigCommerce Enterprise charges zero transaction fees regardless of which payment gateway you use. This is one of BigCommerce’s strongest competitive advantages and can represent significant savings for businesses with preferred payment relationships.

App and Extension Costs

Both platforms rely on apps for functionality beyond their core offering, but the dynamics differ.

Shopify’s app ecosystem is vastly larger — over 8,000 apps versus BigCommerce’s roughly 1,200. However, this means Shopify sometimes pushes functionality to apps that BigCommerce includes natively. Faceted product filtering, for example, is native in BigCommerce but requires an app on Shopify.

A typical mid-market store on Shopify Plus might spend £300-£800/month on apps. The equivalent BigCommerce store might spend £100-£400/month because more features are included by default.

Development Costs

Custom development costs depend heavily on what you are building, but the labour market matters. There are significantly more Shopify developers available than BigCommerce developers. This affects both cost and speed — Shopify projects typically have shorter timelines and lower rates because of supply dynamics. BigCommerce development is often excellent but can be harder to source, particularly in the UK.

Feature Comparison

Storefront and Themes

Shopify Plus uses Liquid as its templating language and Online Store 2.0 as its theme framework. Themes are well-structured and extensively documented. The theme ecosystem is large, with hundreds of free and paid options. Customisation is straightforward for developers familiar with Liquid.

BigCommerce uses Stencil, its own theme framework built on Handlebars.js. Stencil themes are capable and offer good performance, but the ecosystem is smaller and the documentation, while adequate, is less comprehensive than Shopify’s. BigCommerce has been investing in headless commerce more aggressively, so their Stencil investment has somewhat plateaued.

Edge: Shopify Plus for theme ecosystem and developer availability. BigCommerce for native theme features out of the box.

Headless Commerce

Both platforms support headless commerce, but they approach it differently.

Shopify Plus offers the Storefront API and Hydrogen (its React-based headless framework) with Oxygen hosting. The headless story is maturing but still feels secondary to the monolithic Liquid experience.

BigCommerce has positioned itself as headless-first in its enterprise messaging. It offers open APIs, pre-built integrations with Next.js and Gatsby, and does not charge extra for API usage. If you are committed to a headless architecture, BigCommerce’s approach is more natural.

Edge: BigCommerce for headless. Shopify Plus for traditional storefront.

Multi-Channel Selling

Shopify Plus has strong native integrations with Instagram, Facebook, TikTok, Google Shopping, Amazon, and eBay. Managing inventory and orders across channels from a single admin is where Shopify genuinely excels.

BigCommerce offers similar channel integrations but they are typically achieved through partnerships and apps rather than native features. The coverage is comparable but the integration depth varies by channel.

Edge: Shopify Plus for breadth and depth of native channel integrations.

B2B and Wholesale

Shopify Plus added B2B features relatively recently — wholesale channels, company accounts, custom price lists, net payment terms, and volume pricing. These features are functional but newer and less mature.

BigCommerce has offered B2B capabilities for longer, with customer groups, price lists, quote management, and purchase order support as native features. The B2B story is more established. For our perspective on B2B ecommerce specifically, see our B2B Shopify guide.

Edge: BigCommerce for mature B2B. Shopify Plus for businesses where B2B is secondary to DTC.

SEO

Both platforms handle SEO adequately for most businesses, but there are differences:

Shopify Plus generates automatic canonical tags, XML sitemaps, and robots.txt. URL structures are semi-rigid — you cannot fully control URL patterns (products are always at /products/, collections at /collections/). Auto-generated redirects on URL changes are helpful.

BigCommerce offers more URL flexibility, allows full robots.txt customisation, and provides automatic image optimisation with WebP. URL structures are more configurable, which SEO-focused teams appreciate.

Edge: BigCommerce for SEO flexibility. Shopify Plus for SEO simplicity (less to get wrong).

International Selling

Shopify Plus includes Shopify Markets, which handles multi-currency, multi-language, localised pricing, and duties and taxes. The expansion store model lets you run up to 9 additional stores for different regions at no extra cost.

BigCommerce supports multi-currency and multi-language but the implementation requires more manual configuration. Multi-storefront is available on Enterprise plans.

Edge: Shopify Plus, significantly, for international expansion.

Performance and Reliability

Both platforms are hosted and manage their own infrastructure, so uptime and performance are their responsibility rather than yours.

Shopify Plus has historically delivered strong uptime — its CDN and infrastructure are built for the scale of Black Friday/Cyber Monday traffic. Page speed is generally good out of the box, though app bloat can degrade it.

BigCommerce also delivers reliable uptime and good base performance. It tends to be less affected by extension bloat because more features are native, which means fewer third-party scripts loading on the frontend.

Both platforms handle traffic spikes without the kind of infrastructure planning that self-hosted platforms like Magento require. This is the core advantage of hosted commerce.

Support and Ecosystem

Shopify Plus assigns a dedicated Merchant Success Manager, offers priority support, and provides access to the Shopify Plus Academy. The partner ecosystem is enormous — finding Shopify development agencies, designers, and consultants is straightforward anywhere in the world.

BigCommerce Enterprise offers dedicated account management and priority support. The partner ecosystem is smaller but growing. Finding BigCommerce-specialist agencies is harder, particularly outside the US and Australia.

Edge: Shopify Plus for ecosystem depth and partner availability, especially in the UK and Europe.

Who Should Choose Shopify Plus

Shopify Plus tends to be the better fit when:

  • Your business is primarily DTC and multi-channel selling is important
  • You want operational simplicity and are willing to trade some flexibility for it
  • International expansion is on your roadmap in the next 12-24 months
  • You want access to the largest ecosystem of apps, themes, and development talent
  • You use or plan to use Shopify Payments as your primary payment processor
  • Speed to market matters more than architectural perfection

Who Should Choose BigCommerce Enterprise

BigCommerce Enterprise tends to be the better fit when:

  • B2B is a primary revenue channel and you need mature wholesale features
  • You have strong payment gateway preferences and want to avoid transaction fee penalties
  • Headless commerce is your long-term architecture strategy
  • You want more features natively and prefer fewer third-party app dependencies
  • SEO flexibility is a high priority and you want full URL control
  • You have technical resources and want more control over the platform’s behaviour

The Migration Question

If you are currently on another platform — particularly Magento, WooCommerce, or a legacy system — the migration itself is often a larger consideration than the feature comparison. Both Shopify Plus and BigCommerce have established migration paths, but the availability of experienced migration partners varies significantly.

For Magento-to-Shopify migrations specifically, the ecosystem of tools and experienced agencies is more mature. Magento-to-BigCommerce migrations are equally viable technically but may require more specialist sourcing.

Our Perspective

We build on Shopify Plus and recommend it for most mid-market ecommerce businesses. Our reasoning is pragmatic rather than tribal — the ecosystem depth, the pace of platform development, the international expansion capabilities, and the availability of development talent make it the lower-risk choice for most businesses we work with.

That said, we have recommended BigCommerce for clients where B2B was the primary use case and Shopify’s B2B features were not yet mature enough, or where payment gateway flexibility was a genuine financial consideration.

The right platform is the one that matches your specific business requirements, growth trajectory, and operational preferences. If you would like help evaluating which platform fits your situation, get in touch — we will give you an honest recommendation even if the answer is not Shopify.
