Shopify and BigCommerce are the two enterprise-leaning names that often face off when a US business outgrows a basic builder. Shopify wins attention with the largest app ecosystem in commerce and its own integrated payments. BigCommerce counters with a strong built-in feature set and, crucially, no extra platform transaction fee on any gateway. The right pick comes down to whether you value the deepest app store and Shopify's own payments, or the freedom to use any processor without a penalty, set against BigCommerce's sales-gated plans.
Pricing and plans compared
The headline plans land in similar territory, but two structural differences shape the real cost. First, payments: Shopify includes its own processing and adds a fee when you use a third-party gateway, while BigCommerce adds no extra platform transaction fee on any gateway, so you can keep your preferred processor without a penalty. For a merchant wedded to a particular processor, that alone can tip the math toward BigCommerce. Second, plan gating: BigCommerce gates its tiers by annual online sales volume, so a growing store can be forced up to a pricier plan purely because turnover crossed a threshold, whereas Shopify moves you up its tiers to unlock features and lower rates rather than because of a sales ceiling.
Both bill US merchants natively in US dollars, so the invoice is a fixed amount each month with no exchange rate to track. The comparison table on this page shows each platform's current plan pricing, so you can weigh the fee model and the sales gating against your own volume and payment setup rather than the headline figure.
Who each one is for
Shopify is for merchants who want the broadest ecosystem and are happy to use its own payments. If you value thousands of vetted apps and a platform with the largest commerce community behind it, and you are content with Shopify Payments or accept the third-party gateway fee, Shopify gives you the most extensible store and the smoothest setup.
BigCommerce is for merchants who want a strong out-of-the-box feature set and freedom over payments. If keeping your own processor without an extra fee matters, you prefer more functionality built in rather than added through apps, and you can work with sales-gated plans, BigCommerce rewards you with no transaction-fee penalty and a capable platform that needs fewer add-ons to do the job.
Ease of use and selling tools
Both are mature, capable platforms and neither is hard to run once set up. Shopify is known for a polished, beginner-friendly admin and the reassurance of a vast app store when you need an extra capability. BigCommerce tends to put more features in the box by default, which means less reliance on third-party apps but a slightly more involved interface as a result. For day-to-day selling, inventory, and order management, both handle a serious catalog comfortably. The practical difference is philosophy: Shopify keeps the core lean and extends through apps, while BigCommerce builds more in from the start.
AI and integrations
AI is where the gap is most visible. Shopify has built AI into the platform with Sidekick, an assistant that helps set up the store, write product and marketing copy, and answer questions about your shop, and it has opened a Storefront MCP so AI agents can interact with your store as agentic commerce takes shape. BigCommerce has been adding AI capabilities too, particularly around merchandising and content, and its open, API-first architecture makes it straightforward to connect external AI and headless tooling. On integrations more broadly, Shopify's curated app store is the larger of the two by a wide margin, giving a one-click route to thousands of vetted add-ons, while BigCommerce leans on a strong built-in feature set plus an open API that suits more bespoke or headless builds. The trade-off mirrors the platforms: Shopify offers the deepest packaged AI and app layer, BigCommerce offers fewer packaged add-ons but more open connectivity.
US considerations
For a US merchant the good news is that both Shopify and BigCommerce bill natively in US dollars, so your invoice is a fixed amount with no exchange rate to track. Both connect to the US payment methods and gateways American shoppers expect, with BigCommerce's no-extra-fee model giving you a free hand to pick a US-friendly processor without a penalty. Both also handle US sales tax through built-in tools or integrations, so the comparison comes down to how you weigh the deepest app store against payment freedom rather than anything country-specific in the billing. For a merchant who prizes the broadest ecosystem, Shopify is the draw; for one who prizes payment freedom, BigCommerce's fee model is the one to weigh.
Pros and cons for this matchup
Shopify wins on the largest app ecosystem, its own integrated payments, plans that are not gated by sales volume, and AI built for running a shop, all billed in dollars. Its trade-offs are the extra fee on third-party payment gateways and a leaner core that leans on apps for some capabilities.
BigCommerce wins on no extra platform transaction fee on any gateway, a strong built-in feature set, and an open, API-first architecture. Its trade-offs are plans gated by annual sales volume that can force an upgrade as you grow, and a smaller app store than Shopify's.
The verdict
For most US merchants who want the broadest ecosystem and a platform that does not push them up a tier just for growing, Shopify is the more comfortable pick, provided they are happy with its own payments or accept the third-party gateway fee. BigCommerce earns its place when payment freedom is the priority: if keeping your own processor without an extra fee matters, and you prefer more features built in, its no-extra-fee model is a genuine advantage, as long as you can work with sales-gated plans. It comes down to one question: do you want the deepest app store and Shopify's own payments, or the freedom to use any processor without a penalty? Answer that and the choice is clear.
