Quick summary
For most UK merchants, Shopify is the stronger choice over BigCommerce due to its larger app ecosystem, better theme quality, and lower friction for new stores. BigCommerce is worth considering for merchants who need native multi-storefront management, more flexible product variant structures, or no-transaction-fee payment processing from launch.
BigCommerce and Shopify are both credible enterprise ecommerce platforms. The comparison matters because they are pitched at similar merchants, both support headless and composable commerce, and both have UK merchant bases. But they are not interchangeable, and the differences are meaningful enough to drive the right choice for specific situations.
If you are evaluating both platforms, this is the honest comparison rather than the marketing version.
The headline difference
Shopify is the dominant SaaS ecommerce platform by merchant count, app ecosystem size, and brand recognition. BigCommerce is a strong alternative with a genuinely different stance on a few key issues: no transaction fees on any plan, stronger native B2B capabilities at the standard plan level, and multi-currency handling that is built in rather than bolted on.
The rough analogy: BigCommerce does more out of the box without third-party apps. Shopify has a far larger ecosystem to fill in the gaps that native features do not cover.
Where BigCommerce wins
No transaction fees on any plan: BigCommerce does not charge transaction fees regardless of which payment gateway you use. Shopify charges transaction fees on all plans unless you use Shopify Payments (not available in all countries) or pay for Plus. For UK merchants using a preferred payment gateway rather than Shopify Payments, this is a direct cost difference.
At £2m annual GMV on Shopify Advanced with a third-party processor, you pay 0.5% in transaction fees: £10,000/year. On BigCommerce, that number is zero.
Stronger native multi-currency: BigCommerce has had robust native multi-currency support for longer than Shopify. If you are selling to multiple international markets and want native currency display and checkout without a third-party app, BigCommerce's implementation is more complete at the standard plan level.
Native B2B on standard plans: BigCommerce's B2B Edition includes customer groups, price lists, order approval workflows, and a trade portal without requiring an enterprise plan. Shopify's equivalent (native B2B with company profiles and net terms) is locked to Plus. For merchants who need B2B features but do not want to commit to Plus pricing, BigCommerce is cheaper access to similar functionality.
Unlimited product variants natively: BigCommerce does not cap the number of variants per product. Shopify's standard limit is 100 variants per product (configurable with apps or on Plus, but still an architectural consideration for merchants with large variant matrices).
Revenue-based plan scaling is more predictable: BigCommerce's pricing scales based on annual online sales revenue, not features. You pay more as you grow, but the feature set is largely consistent across plans. Shopify's feature gating (where specific capabilities are only available at higher plan tiers) can create awkward upgrade pressure.
Where Shopify wins
The app ecosystem: Shopify's App Store has over 8,000 apps compared to BigCommerce's marketplace of around 1,500. This matters because the long tail of niche integrations, emerging marketing tools, and specialist functionality tends to arrive on Shopify first (and sometimes only). If you need a specific integration with a UK-specific tool, Shopify is more likely to have it.
Theme quality and developer tooling: Shopify's theme ecosystem is larger and generally higher quality. The Liquid templating language and Shopify CLI are well-documented and widely understood by developers. BigCommerce's Stencil framework is capable but has a smaller talent pool and fewer high-quality commercial themes.
Merchant community: Shopify's merchant community is significantly larger. When you need answers, troubleshooting help, or conversion advice from other merchants, the Shopify community (forums, subreddits, agencies, Facebook groups) is vastly deeper.
Checkout quality and conversion: Shopify's hosted checkout has been consistently benchmarked as high-performing. Its Shop Pay accelerated checkout, with a network of millions of existing users, reduces friction for returning buyers across the entire Shopify ecosystem. BigCommerce does not have an equivalent accelerated checkout network.
Headless commerce with Hydrogen: Shopify's Hydrogen framework (React-based) is the strongest purpose-built headless commerce framework available on any SaaS platform. BigCommerce supports headless architectures but without an equivalent proprietary framework. If you are building a composable or headless front end, Shopify's tooling is more mature.
Multi-channel selling: Shopify's native integrations with TikTok Shop, Instagram, Facebook, Pinterest, Google, and Amazon are tightly maintained and widely used. The Shopify admin surfaces channel performance clearly. BigCommerce has multi-channel capability but the depth and reliability of channel integrations lags Shopify.
Pricing comparison
| Plan | Shopify | BigCommerce |
|---|---|---|
| Entry level | Basic: £29/month | Standard: £29/month |
| Mid tier | Shopify: £79/month | Plus: £79/month |
| Advanced | Advanced: £299/month | Pro: £224/month |
| Enterprise | Plus: $2,500/month | Enterprise: custom |
| Transaction fees | 0.5% to 2% (third-party) | None |
| Staff accounts (mid tier) | 5 | Unlimited |
The plan-to-plan pricing is comparable. The material difference is transaction fees. BigCommerce's advantage is most pronounced for merchants using third-party payment processors at mid-to-high GMV.
B2B capabilities comparison
| Feature | Shopify Plus B2B | BigCommerce B2B Edition |
|---|---|---|
| Customer groups with price lists | Yes | Yes |
| Company profiles and contacts | Yes | Yes |
| Net payment terms | Yes (native) | Yes |
| Order approval workflows | Limited | Yes (native) |
| Requisition lists | No | Yes |
| Shared company payment methods | Limited | Yes |
| Quote management | No (third-party) | Yes |
| Available without Plus | No | Yes (B2B Edition add-on) |
For enterprise B2B requirements, BigCommerce B2B Edition has more complete native coverage. For straightforward wholesale (price lists, net terms, company portals), Shopify Plus B2B is comparable.
UK market considerations
Both platforms support GBP natively. Both have Shopify Payments and equivalent payment gateways that cover major UK processors (Stripe, Barclaycard, Adyen, Worldpay).
Shopify has a larger UK agency and developer ecosystem. If you need to find a specialist agency, Shopify Partners are more numerous in the UK market.
BigCommerce has a UK merchant base but a smaller UK agency community. Finding a BigCommerce specialist agency for complex UK projects requires more research.
VAT and tax handling is comparable on both platforms for standard UK VAT scenarios. Complex tax scenarios (OSS for EU selling, specific exemptions) typically require a third-party tax app on both platforms.
The honest verdict
Choose Shopify if: You want the largest app ecosystem, the best headless development framework, strong multi-channel selling, or you are using Shopify Payments and the transaction fee issue is therefore irrelevant.
Choose BigCommerce if: You are paying material transaction fees on a third-party processor and do not want to use Shopify Payments, you need native B2B features without committing to Plus pricing, or you need unlimited product variants without architectural workarounds.
For most UK merchants, Shopify is the right choice because the ecosystem depth, merchant community, and long-term development investment outweigh BigCommerce's structural advantages. The transaction fee point is the one area where the numbers might shift the calculation, and it is worth running them explicitly for your store.
Key actions to take now
- Calculate your actual transaction fee exposure on your current plan: If you are on Shopify with a third-party processor, calculate what you pay annually in transaction fees. Compare this to the BigCommerce equivalent (zero) at the same plan tier.
- List your B2B requirements specifically: If you need order approval workflows or quote management natively, BigCommerce B2B Edition covers this without an enterprise contract. Map your requirements against both platforms before deciding.
- Check your third-party integrations on both marketplaces: For every app or tool you currently use or plan to use, verify it is available on both platforms. Pay particular attention to any UK-specific tools (accounting software, fulfilment providers, carriers).
- Request a BigCommerce demo if transaction fees are a material concern: BigCommerce's sales team can demo the platform and provide a custom pricing conversation if you have significant volume.
- Evaluate Shop Pay's value for your customer base: If your customers are already Shop Pay users (300 million+ accounts globally), the accelerated checkout benefit on Shopify is tangible and measurable. If your audience skews away from this demographic, the advantage is less relevant.
- Do not switch platforms for marginal reasons: Both platforms are capable at enterprise scale. The switching cost of a platform migration (typically £20,000 to £100,000 for a mid-market store) means the case for switching needs to be clear and financially justified, not driven by feature curiosity.
Frequently Asked Questions
Is BigCommerce better than Shopify for B2B? For complex B2B with order approval workflows and requisition lists, BigCommerce B2B Edition has more complete native functionality and it is available without an enterprise tier contract. For straightforward wholesale (price lists, net terms, company portals), Shopify Plus B2B is comparable. The right choice depends on the complexity of your specific B2B requirements and whether you are already on or considering Shopify Plus.
Does BigCommerce have transaction fees? No. BigCommerce does not charge transaction fees on any plan regardless of which payment gateway you use. This is one of its clearest differentiators from Shopify, where transaction fees apply unless you use Shopify Payments or upgrade to Plus.
Can BigCommerce handle headless ecommerce? Yes. BigCommerce supports headless architectures and offers API-first capabilities for composable commerce builds. However, it does not have an equivalent to Shopify's Hydrogen framework. Developers building headless on BigCommerce typically use React or Next.js with BigCommerce's Storefront API, which is well-documented but lacks the purpose-built tooling that Hydrogen provides.
Which platform is growing faster? Shopify has consistently grown faster in merchant count and GMV terms. However, BigCommerce has been specifically targeting enterprise and mid-market merchants and has been growing in that segment. For most UK merchants, platform growth trajectory is less relevant than which platform fits your requirements today and for the next three to five years.
