Shopify and BigCommerce are both hosted SaaS ecommerce platforms, which means they share more in common than either shares with self-hosted platforms like WooCommerce or Magento. Both handle hosting, security, SSL, and platform updates. Both offer monthly subscription pricing. Both are capable of powering successful online stores.

But beneath these surface similarities, they have meaningfully different approaches to pricing, built-in features, ecosystem development, and market positioning. For UK brands in a growth phase, these differences matter.

This comparison is balanced. BigCommerce has genuine advantages over Shopify in several areas. I will be specific about where each platform wins and why.

Platform overview

Shopify powers over 4 million stores globally and has become the dominant SaaS ecommerce platform. Its strategy centres on a lean core platform supplemented by a vast app ecosystem. Shopify keeps its core product focused and relies on third-party developers to extend functionality through apps.

BigCommerce takes a different approach, often described as "open SaaS." It builds more features directly into the platform, reducing reliance on third-party apps. BigCommerce also offers headless commerce capabilities and API-first architecture as core selling points, positioning itself as the platform for brands with more technical ambitions.

Both platforms are legitimate choices for UK ecommerce brands. The right one depends on your specific priorities, technical capabilities, and growth trajectory.

Pricing and revenue thresholds

Both platforms offer tiered pricing, but BigCommerce has a unique wrinkle: revenue-based plan thresholds.

Shopify pricing

Shopify Basic (£25/month), Shopify (£65/month), and Advanced (£399/month). Plans are differentiated by features, not revenue. You can do £10 million on the Basic plan if you want — though you would miss out on features like advanced reporting and lower credit card rates. Shopify charges additional transaction fees (0.5-2%) if you use a payment gateway other than Shopify Payments.

BigCommerce pricing

BigCommerce Standard (from approximately £23/month), Plus (from approximately £71/month), and Pro (from approximately £269/month). Critically, each plan has an annual online sales limit. If your store exceeds £38,000/year on Standard, you must upgrade to Plus. Exceed £135,000/year and you need Pro. Beyond £340,000/year, you are looking at Enterprise pricing.

BigCommerce does not charge additional transaction fees on any plan, regardless of your payment gateway. This is a genuine financial advantage, particularly for brands using gateways other than the platform's preferred option.

Built-in features

This is where BigCommerce genuinely differentiates itself. BigCommerce includes many features natively that Shopify requires apps for.

BigCommerce built-in advantages

  • Product variants. BigCommerce supports up to 600 variant combinations per product versus Shopify's 100. For brands with complex product configurations, this is significant.
  • Customer groups and pricing. Built-in customer segmentation with group-specific pricing, enabling B2B and wholesale pricing without apps.
  • Multi-currency. Native multi-currency support across all plans.
  • Faceted search. Built-in product filtering with customisable facets.
  • Abandoned cart recovery. Available on all plans (Shopify restricts this on its lowest tier).
  • Real-time shipping quotes. Available on lower-tier plans without additional apps.

Shopify built-in advantages

  • POS integration. Shopify POS is deeply integrated with the platform for unified online and in-store selling.
  • Shop Pay. The accelerated checkout network provides a conversion advantage through saved customer details across the Shopify ecosystem.
  • Shopify Capital. Integrated business financing based on store performance data.
  • Shopify Inbox. Built-in customer chat with automated responses.
  • Shopify Flow. Visual automation builder for backend workflows (available on higher plans).

Checkout and conversion

Shopify has a structural advantage in checkout that is difficult for BigCommerce to replicate.

Shopify's checkout has been optimised across billions of transactions and hundreds of millions of shoppers. Shop Pay, the accelerated checkout, stores payment and shipping information across the entire Shopify ecosystem — meaning a customer who has purchased from any Shopify store can check out on yours with a single tap. This network effect is unique to Shopify.

BigCommerce's checkout is clean, functional, and fully customisable. It supports one-page checkout, optimised mobile checkout, and various payment wallets. But it does not have an equivalent to Shop Pay's cross-platform network effect.

For a UK brand doing £500k in annual revenue, even a 0.5% difference in checkout conversion rate represents £2,500 per year. This is a meaningful competitive advantage for Shopify.

SEO capabilities

BigCommerce has a genuine edge in native SEO capabilities.

BigCommerce SEO advantages

  • URL flexibility. BigCommerce allows fully customisable URL structures without the /products/, /collections/, or /pages/ prefixes that Shopify enforces. This gives you cleaner, shorter URLs.
  • Automatic image optimisation. BigCommerce includes built-in image optimisation with WebP conversion.
  • Microdata. Rich product schema markup is built into themes.
  • 301 redirects. Automatic redirect creation when URLs change.

Shopify SEO advantages

  • Page speed. Shopify's global CDN and optimised infrastructure typically deliver faster load times.
  • SEO app ecosystem. A larger selection of specialist SEO apps and tools.
  • Content marketing. Shopify's blogging tools, while basic, are continuously improving.

Both platforms can rank well in search. BigCommerce's URL flexibility is a real advantage for brands where clean URL structure is important. Shopify's performance advantage is meaningful given that speed is a ranking factor. For a broader SEO comparison, see our original BigCommerce comparison.

App ecosystem

This is Shopify's strongest competitive moat. The Shopify App Store has over 10,000 apps compared to BigCommerce's approximately 1,200. The difference is not just in quantity — it is in depth. For virtually any ecommerce need, Shopify has multiple competing apps, driving quality up and prices down.

BigCommerce compensates by building more features natively, reducing the need for third-party apps. But for specialist requirements — advanced loyalty programmes, sophisticated subscription management, AI-powered personalisation — Shopify's app ecosystem offers more options.

BigCommerce's app marketplace is adequate for common needs but cannot match Shopify's depth in niche ecommerce tooling.

Design and themes

Both platforms offer theme-based design systems. Shopify's Theme Store has more options, including both free and premium themes. BigCommerce's theme selection is smaller but includes well-designed options.

Shopify's Online Store 2.0 architecture provides section-based customisation that non-technical users can manage through the visual editor. BigCommerce's Page Builder offers similar drag-and-drop capabilities.

For custom theme development, Shopify uses Liquid templating with extensive documentation and a large developer community. BigCommerce uses Stencil, which is well-documented but has a smaller developer pool, particularly in the UK.

Theme and design ecosystem comparison

Multi-channel selling

Both platforms support multi-channel selling across social media and marketplaces. Shopify's integrations with Facebook, Instagram, TikTok, Google Shopping, Amazon, and eBay are deeper and more mature. BigCommerce supports the same channels but with fewer native integration features.

Shopify's advantage here is partly a function of market share — platform partners prioritise Shopify integrations because of its larger merchant base.

B2B capabilities

BigCommerce has stronger native B2B features. Customer group pricing, quote management, purchase orders, and company account hierarchies are built into the platform. For brands that sell to both consumers and businesses, BigCommerce's B2B toolkit is more comprehensive without requiring additional apps.

Shopify has expanded its B2B capabilities, particularly with Shopify Plus, which now includes wholesale pricing, company profiles, and draft orders. But on lower-tier plans, B2B functionality requires third-party apps.

Scalability and enterprise

Both platforms offer enterprise tiers — Shopify Plus and BigCommerce Enterprise. Shopify Plus starts at approximately £1,750/month and provides checkout customisation, advanced automation, dedicated support, and higher API limits. BigCommerce Enterprise pricing is custom but typically comparable.

Shopify Plus has significantly more UK merchants than BigCommerce Enterprise, which means a larger community, more case studies, and more agencies with enterprise experience. This ecosystem advantage should not be underestimated when evaluating enterprise options. For brands considering the enterprise tier, see our Shopify vs Magento comparison for enterprise-level analysis.

UK market considerations

Developer availability

Shopify developers are significantly more available in the UK than BigCommerce developers. The Shopify Partner ecosystem has thousands of UK-based agencies and freelancers. BigCommerce's UK partner network is much smaller, which can affect your ability to find qualified development support.

VAT and tax

Both platforms handle UK VAT competently. BigCommerce has slightly more granular tax configuration options natively, while Shopify handles the common UK VAT scenarios well with less configuration effort.

Payment processing

Both platforms support UK payment gateways. Shopify Payments (powered by Stripe) is available in the UK. BigCommerce supports multiple gateways without additional transaction fees, which is an advantage for brands committed to a specific gateway. Both platforms ensure your website can process payments smoothly for UK customers.

The verdict
