The Mid-Market Is Becoming a Battleground
Shopify built its reputation on small businesses – the solo founders, the Etsy graduates, the direct-to-consumer brands that needed a clean storefront and a payment processor without a six-figure setup fee. That story is still accurate, but it no longer captures the whole picture. Over the past two years, Shopify has been systematically expanding upmarket, adding enterprise-grade infrastructure, dedicated merchant success programs, and a B2B commerce suite that targets exactly the kind of mid-sized retailer that BigCommerce has spent years courting.
BigCommerce occupies a specific and carefully defended niche. It sells itself as the platform for businesses that have outgrown the simplicity of entry-level tools but aren’t ready – or willing – to pay for Salesforce Commerce Cloud or Adobe Commerce. That sweet spot, roughly $5 million to $100 million in annual online revenue, has been BigCommerce’s home territory. Shopify is now moving in, not by abandoning its SMB roots, but by building a parallel infrastructure that makes the jump from small to enterprise easier on a single platform.
What Shopify Actually Built
The commercial centerpiece of Shopify’s enterprise push is Shopify Plus, but the product has evolved well beyond a higher pricing tier. The platform now includes customizable checkout logic through its Checkout Extensibility framework, which allows merchants to inject loyalty programs, custom shipping logic, and B2B-specific payment terms directly into the purchase flow without touching core code. That level of flexibility was previously a major selling point for BigCommerce, which competes partly on its open SaaS architecture and native B2B features.
Shopify has also invested heavily in its Markets Pro product for cross-border commerce, its Audiences advertising tool for paid media targeting, and a native POS system that syncs physical and digital inventory at scale. The combination matters because mid-market retailers don’t just run one channel. They run stores, pop-ups, wholesale portals, and international storefronts simultaneously, and they need a platform that doesn’t require four different vendors to manage it all. Shopify is increasingly that single platform, which changes the conversation with any merchant evaluating BigCommerce.
The B2B push deserves specific attention. Shopify’s native B2B features – including company accounts, custom price lists, and net payment terms – were added to Plus in 2022 and have been expanded steadily since. BigCommerce has offered B2B functionality through its dedicated B2B Edition for longer, and its architecture was designed with complex catalog and pricing scenarios in mind. But Shopify’s B2B build is catching up faster than BigCommerce would prefer, and it comes packaged inside a platform that most merchants already know how to use.
Speed of iteration is part of Shopify’s structural advantage here. The company ships product updates at a pace that mid-market merchants notice. Every Shopify Editions release – its biannual product announcement event – arrives with dozens of new features across the stack. BigCommerce releases updates too, but the volume and marketing weight behind Shopify’s announcements create a perception of momentum that is difficult to counter, especially when you’re selling to merchants who read trade press and follow ecommerce Twitter.
BigCommerce’s Defensive Position
BigCommerce is not standing still. The company has doubled down on its headless commerce positioning, promoting its API-first architecture as the right choice for brands that want to build custom front-end experiences without being constrained by a platform’s native theme engine. It has also leaned into its partnerships with ERP and CRM vendors, making the case that complex businesses need deep integrations, not surface-level connections.
The challenge is that headless commerce, while genuinely useful for large enterprises with dedicated development teams, is a harder sell to the mid-market buyer who wants power without complexity. Shopify’s Hydrogen framework and Oxygen hosting infrastructure give developers a headless pathway on Shopify too, narrowing the gap. BigCommerce’s argument that it is “the more open platform” is technically defensible, but it requires a technical buyer in the room to land. Many mid-market merchants don’t have that buyer.
Merchant Migration and the Switching Cost Question
Platform migrations are expensive, disruptive, and time-consuming. This is the single biggest protection BigCommerce has against losing its installed base to Shopify. A retailer running complex custom integrations, proprietary pricing rules, and a multi-storefront setup does not replatform casually. The switching cost is real, and it creates a natural retention buffer even when a competitor’s feature set looks attractive on paper.
But switching costs work both ways. Merchants who are currently on Shopify’s SMB tiers and growing into the mid-market have almost no reason to leave the platform and migrate to BigCommerce. They’re already trained on Shopify’s admin, their teams know the tool, and the marginal cost of upgrading to Shopify Plus is a fraction of what a full migration would cost. This is where Shopify’s enterprise push does its most effective work – not by stealing BigCommerce’s existing customers, but by intercepting the next cohort of mid-market merchants before BigCommerce even gets the sales call.
A growing number of agencies that specialize in mid-market ecommerce builds are reporting that client conversations now default to Shopify Plus as the starting assumption, with BigCommerce entering the conversation only when a specific technical requirement rules Shopify out. That default position is difficult to reverse through product updates alone. It lives in the imagination of merchants and the recommendation habits of the consultants they trust, and this pattern of default platform preference is one Shopify has deliberately cultivated across verticals.
Where This Leaves the Competition
BigCommerce’s stock price and revenue growth have both lagged behind the trajectory the company projected when it went public in 2020. The platform still powers some large, sophisticated brands, and its enterprise sales team continues to win deals – particularly in sectors like manufacturing, distribution, and complex wholesale where B2B requirements are genuinely deep. But the volume play, the mid-market merchant who is scaling fast and needs a platform that can grow with them, is increasingly Shopify’s to lose.
There is one scenario where BigCommerce recovers ground: if Shopify’s enterprise complexity grows to the point where its simplicity advantage erodes. Shopify built its brand on being easy. If Plus becomes hard enough that merchants need expensive agency support to configure it properly, the value proposition weakens. Some Plus merchants are already reporting longer implementation timelines and higher agency fees than they expected. That tension – between enterprise power and the ease of use that made Shopify famous – is the one gap BigCommerce still has a legitimate claim on.
Whether BigCommerce can exploit that gap before Shopify smooths it out is the central question for the next two years of this competition. Shopify’s developer ecosystem is enormous, its capital position is strong, and its brand recognition among non-technical founders is unmatched. BigCommerce is a genuinely well-built platform competing against a company that has made capturing the mid-market a stated strategic priority – and has the resources to stay patient until the numbers move.
