BigCommerce vs Shopify: Which Platform Should You Choose?
If you're comparing BigCommerce and Shopify, you've already done one sensible thing: narrowed the field. Both are credible platforms, widely deployed, and capable of supporting serious ecommerce operations.
The question isn't whether either one works — it's which fits your situation, and whether a platform change is actually the move that will change your numbers.
This article compares the two in terms of architecture, cost, capability, and long-term fit. And what to sort out before you commit to either.
The short answer?
Shopify is the better default for most brands. Deeper ecosystem, larger partner network, lower operational complexity for teams without significant technical resources. If your business is largely B2C, your catalogue is relatively straightforward, and speed to market matters, Shopify (or Shopify Plus) is the more pragmatic choice.
BigCommerce earns its place in specific circumstances: complex B2B requirements, multi-storefront architecture, catalogue complexity that would require multiple Shopify apps to manage, or situations where transaction fees at volume tip the scales in BigCommerce's favour.
If those conditions apply, BigCommerce deserves serious consideration.
Where Shopify has the advantage
The app marketplace is the clearest difference. Shopify's is considerably larger than BigCommerce's. For most requirements — subscriptions, loyalty, reviews, PIM connectivity, returns management — you'll find more options, more integrations, and more active development on Shopify. That matters when your roadmap involves third-party tools, because the availability of well-maintained apps directly affects how quickly you can move.
There are also more Shopify agencies, developers, and specialist knowledge available in the market. You get more choice when hiring and more leverage when changing partners. The BigCommerce partner ecosystem is smaller, which can create real dependency if your relationship with your agency deteriorates.
For a standard B2C build, Shopify's tooling, theme ecosystem, and deployment workflows are faster. And day-to-day, it's easier to operate for non-technical teams. Content management, product management, discount logic, and most marketing integrations are all manageable without developer involvement.
Where BigCommerce has the advantage
BigCommerce's B2B Edition handles customer-specific pricing, quote management, purchase order workflows, and tiered accounts natively. Shopify Plus can be configured for B2B requirements, but it means more custom development or dependence on specific apps. If B2B is central to your model — not a secondary channel — BigCommerce's native architecture is a genuine advantage over what Shopify offers out of the box.
The multi-storefront question is also worth taking seriously. BigCommerce lets you run multiple storefronts — different brands, regions, or customer segments — from a single backend instance. Shopify handles this with Markets or separate stores, which creates more fragmentation in reporting and operations. If brand separation or significant regional complexity is in your model, that's worth examining closely.
On transaction fees: Shopify charges one if you don't use Shopify Payments. For businesses processing at high volume or using specific payment gateways for compliance or commercial reasons, this adds up. BigCommerce charges no transaction fees regardless of payment provider.
BigCommerce also handles complex catalogues more gracefully out of the box — large SKU counts, complex variant structures, and custom fields. If your catalogue is genuinely complex, this affects both build cost and ongoing management overhead.
Cost comparison
Neither platform is cheap at scale, and cost comparisons between the two are often misread because people compare list prices rather than total cost of ownership.
Shopify charges platform fees based on plan tier, plus transaction fees if not using Shopify Payments, plus app subscription costs. For a brand at £5m revenue using Shopify Plus with five or six apps, total platform spend, including apps, typically sits between £2,000 and £4,000 per month before any development cost. Transaction fees, if applicable, are on top.
BigCommerce charges based on revenue bands rather than a fixed plan fee. Costs rise as revenue grows, making revenue growth less predictable for some businesses. App and integration costs exist, but the marketplace is smaller, so average app spend tends to be lower. No transaction fees.
The cost difference at most revenue levels is not dramatic. It becomes more significant at high volume with specific payment gateway requirements, or at the point where Shopify app dependency has grown enough that BigCommerce's native capability would have replaced several paid tools.
Model the cost over three years, including anticipated app spend and transaction fee exposure, before drawing conclusions from plan pricing.
Integration and architecture
Both platforms integrate with the major ERPs, PIMs, and marketing tools. Shopify has more pre-built connectors and better-documented integrations for most tools in the mid-market stack. BigCommerce's API is well-regarded technically, and for custom integrations there's no meaningful quality difference — the cost difference usually comes down to how much pre-built work already exists.
If your integration map includes Sage, NetSuite, or Microsoft Dynamics, check the connector landscape for your specific version and use case. Generic "we integrate with X" claims from both platforms can obscure significant variation in depth and reliability.
On headless: Shopify's Hydrogen framework is more mature and more widely deployed. BigCommerce's Catalyst framework is capable but has a smaller developer community. If headless is on your roadmap, the talent and tooling gap between the two is currently meaningful.
The decision most brands get wrong
The feature comparison is the easy part. The harder part is that most brands in this comparison are mid-consideration on replatforming, and many haven't clearly articulated what they're actually trying to solve.
Platform searches tend to spike when something is visibly broken: revenue has plateaued, conversion is flat, the current platform feels slow or limiting, or the development backlog is growing. None of that automatically points to a platform change.
Conversion problems are usually UX, offer, or traffic quality problems — not platform problems. Speed issues usually stem from hosting, image, and code quality. A growing backlog is a prioritisation and resourcing problem. None of these is fixed by replatforming.
The brands that got the most from a replatform went into it already understanding what was broken, why it was broken, and specifically what the new platform would enable that the current one couldn't. The brands that were disappointed tended to treat the platform change as the diagnosis.
What to establish before you choose
Before the platform decision, there are five questions worth answering honestly.
What is the current platform specifically preventing you from doing? Not in general terms — specifically. If you can't name it, that's a signal.
Where does the platform stop and your team's process begin? Many operational problems get attributed to the platform when they're actually workflow, data management, or resourcing problems. The platform change won't touch those.
What does your integration map look like? List your ERP, PIM, fulfilment systems, and marketing stack. Check the integration landscape for each platform against your actual tools, not generic categories.
What does your business model look like in three years? If significant B2B revenue, multi-brand, or multi-region is on the roadmap, that materially changes the platform fit calculation.
Who owns this decision internally, and what are they optimising for? Platform decisions can be shaped by team familiarity, internal politics, or existing agency relationships.
How to run the decision process
Map your current platform's actual constraints — not a frustration list, a specific list of what you cannot do or cannot do economically. Then check whether those are platform constraints or implementation constraints.
Get cost models over three years, including app spend, transaction fees, and anticipated development costs for migration and post-launch build. Compare those, not plan pricing.
Speak to brands in a similar model who have migrated to each platform. Not agencies — brands. Ask what they underestimated, not what went well.
If you're considering Shopify Plus or BigCommerce Enterprise, engage with the platform's own team. Both offer pre-sales support that includes architecture conversations.
A note on clarity
If you've worked through the questions above and still can't clearly articulate what the new platform would solve, or if the answers suggest the problem might not be the platform, then that's worth thinking more deeply about before committing budget to a migration.

FAQs
Is BigCommerce better than Shopify for B2B?
For businesses where B2B is a primary channel — not a secondary one — BigCommerce's native B2B capability is a meaningful advantage over Shopify's default B2B tooling. Shopify Plus can be configured for B2B, but BigCommerce handles customer-specific pricing, quote workflows, and account management with less reliance on custom development. If B2B is a secondary channel or occasional requirement, Shopify's configuration options are likely sufficient.
Is Shopify cheaper than BigCommerce?
At lower revenue levels, Shopify's plan pricing is often lower. At higher volume — particularly for businesses not using Shopify Payments — transaction fees can make BigCommerce more cost-effective. App spend is typically higher on Shopify because more functionality comes via apps rather than natively. Model the full cost, including apps and transaction fees, over three years before drawing a conclusion.
Can I migrate from Shopify to BigCommerce, or vice versa?
Yes. Both directions are technically achievable. Product data, customer records, and order history can be migrated. Custom theme work, app configurations, and integrations need to be rebuilt. The cost and timeline depend heavily on the complexity of your current setup. A migration is not a lift-and-shift — plan for a meaningful rebuild of anything custom.
Which platform is better for UK ecommerce brands?
Both are used by UK brands at scale. Shopify has a larger UK partner and developer ecosystem, which gives more choice when sourcing agencies and freelancers. BigCommerce is less widely deployed in the UK, so the partner pool is smaller. Neither has a structural advantage for UK-specific trading requirements. Both support GBP, UK payment gateways, and standard UK tax configurations.
What's the difference between Shopify Plus & BigCommerce Enterprise?
Both are the enterprise tiers of each platform. Both unlock higher-volume infrastructure, custom checkout capability, dedicated support, and additional API access. Shopify Plus is more widely deployed and has a larger ecosystem of Plus-specific apps and partners. BigCommerce Enterprise pricing is revenue-banded rather than a fixed annual fee. The right choice depends on your requirements, your team, and your budget.
