BigCommerce vs Shopify Plus for B2B: The 2026 Operator's Guide

Quick verdict: BigCommerce built a solid B2B foundation and then pivoted away from mid-market. Shopify Plus spent 2023 and 2024 closing every major B2B gap that BigCommerce used to own. If you're a manufacturer, distributor, or wholesaler comparing the two in 2026, you're not looking at the same platforms the older comparisons described. The landscape has shifted, and the shift favors Shopify Plus for most B2B operators.

BigCommerce and Shopify Plus are both enterprise ecommerce platforms, but they've been moving in different directions. BigCommerce offers more features built-in out of the box and no transaction fees regardless of your payment processor. Shopify Plus now delivers native B2B capabilities that match BigCommerce's wholesale feature set, a larger app ecosystem, and faster time-to-launch.

For most mid-market B2B operators in 2026, Shopify Plus is the stronger choice.

BigCommerce launched in 2009 and built its reputation on a specific promise: more native functionality than competing platforms, less reliance on apps for standard operations. Merchants with large catalogs, multi-currency requirements, and complex pricing structures found BigCommerce gave them more to work with on day one. That reputation was earned.

The platform's B2B capabilities followed the same philosophy: customer groups, a native promotions engine, flexible faceted navigation, and an open API that made headless builds straightforward. For operators who needed depth before Shopify's B2B native features existed, BigCommerce was a legitimate recommendation. What changed is the company's strategic direction.

Between 2024 and 2026, BigCommerce went through multiple rounds of restructuring. Engineering and support teams were reduced. The product roadmap consolidated around high-volume enterprise retail. SMB investment was pulled back. The mid-market operator, the manufacturer or distributor doing $5M to $50M in annual revenue, stopped being the primary audience for BigCommerce's development resources.

This matters more than it sounds in most comparison posts. When you choose a platform, you're not just choosing what it does today, you're choosing who is actively building for your problems tomorrow. A platform contracting around a narrower enterprise-retail segment is allocating its R&D toward that segment. Mid-market B2B operators are not that segment for BigCommerce right now.

BigCommerce has a capable product. The core features work, the API is solid, and for the right use case it remains a defensible choice. But the directional question is worth asking honestly: is your operation the customer BigCommerce is investing in? For most mid-market manufacturers and distributors, the answer in 2026 is no.

Shopify Plus is Shopify's enterprise tier, starting at approximately $2,300 per month or 0.25% of monthly platform revenue, whichever is higher above a GMV threshold. It runs on infrastructure that processes hundreds of billions in commerce volume annually, with a track record that includes the world's largest single-day ecommerce traffic events.

The more important change for B2B operators happened between 2022 and 2024, and it gets less attention than it should. Shopify rolled out native B2B as a core feature set of Shopify Plus, not an app, not a third-party add-on. Company accounts, B2B-only storefronts, customer-specific price lists, volume pricing, native net payment terms, purchase-order support, and vaulted buyer payment methods are all built into the platform. These were the capabilities BigCommerce had used as a B2B differentiator for years. Shopify Plus now ships with them natively. For more on what changed in recent platform updates, see Shopify Plus B2B feature updates.

For a distributor managing reorders across 40 accounts with different pricing tiers, or a manufacturer running dealer-specific pricing through their store, these features are the difference between a platform that fits and one that requires ongoing workarounds.

Uncap has been a Shopify Platinum Partner since 2013, with over 380 B2B commerce projects delivered. The volume of B2B upgrade activity on Shopify Plus accelerated sharply after these native features shipped, operators who had been holding off specifically because of B2B gaps started moving.

Platform fees are the visible cost. Developer overhead and implementation time are the ones that usually surprise operators.

Shopify Plus starts at $2,300 per month or 0.25% of monthly platform revenue above the threshold, whichever is higher. When you use Shopify Payments, there are no transaction fees; with a third-party processor, Shopify Plus charges 0.15% per transaction. Most B2B operators use either Shopify Payments or configure net payment terms, which means transaction fees are rarely a significant factor.

BigCommerce Enterprise uses custom pricing. The publicly listed plans top out at the Pro tier ($399/month), but Enterprise, the actual equivalent to Shopify Plus for B2B, starts meaningfully higher, expect pricing comparable to or above Shopify Plus at similar GMV. On transaction fees, BigCommerce has a clear advantage: none, regardless of processor. That matters for operations using specialized payment processors, and on paper in a TCO comparison, but for most B2B operators with high average order values and net terms, transaction-fee differences at the Plus/Enterprise level are not the deciding factor.

This is where the comparison often gets misread. BigCommerce's advantage, more native features, comes with an operational reality: a more complex native feature set requires more developer expertise to configure, maintain, and extend. B2B customizations on BigCommerce, customer-group pricing, custom checkout behavior, promotional logic, have historically required developer involvement that adds timeline and ongoing maintenance cost.

Shopify Plus with native B2B reduces this overhead. Customer-specific pricing, B2B checkout, and company-account management are configured in the admin, not in code. Custom business logic that previously required developer hours can often be handled via Shopify Functions or an existing app. For a mid-market operation without a dedicated developer on staff, that means shorter implementation time, lower initial development cost, and less ongoing maintenance spend. The platform with more native features is not automatically the lower-maintenance platform.

The gap that made BigCommerce the default B2B recommendation for years was real. Before Shopify's native B2B rollout, operators who needed customer groups, price lists, and wholesale-channel separation had a legitimate reason to favor BigCommerce. That gap has closed. Here's where both platforms stand on the capabilities that matter for manufacturers, distributors, and wholesalers.

Customer-specific pricing: Both platforms handle this natively, Shopify Plus via customer price lists and company profiles, BigCommerce via customer groups and price lists. Both can handle Account A seeing one price and Account B another.

Company account management: Shopify Plus leads here post-2023. Native company accounts allow multi-location, multi-buyer management under one entity, with buyer-level spending limits and approval routing. BigCommerce customer groups are functional but require more configuration to achieve the same hierarchy.

Net terms and payment flexibility: Shopify Plus has native net terms built into B2B checkout, Net 30/60/90 without third-party apps. BigCommerce handles net terms primarily through app integrations and custom payment configuration.

Checkout customization: Shopify Functions changed the game, business rules and checkout modifications that previously required custom development can now be written as Functions. BigCommerce uses custom checkout templates and Cornerstone theme customization, which require developer involvement for meaningful changes.

Draft orders and sales-assisted commerce: Both support draft orders and rep-created orders. Shopify Plus's draft-order workflow integrates directly with B2B company accounts and buyer profiles, keeping the order in context with the account relationship.

ERP and system integrations: Neither platform ships with native ERP connectivity, both rely on middleware or apps. Uncap Connect handles Shopify-to-ERP integration as a native Shopify app, covering NetSuite, QuickBooks, Microsoft Dynamics, Epicor, Acumatica, and others, orders placed in Shopify create documents in the ERP with no sync window.

Where BigCommerce still holds advantages: a stronger out-of-the-box promotions engine for complex discount structures, more flexible faceted navigation for large catalogs, no transaction fees regardless of processor, and a longer track record in headless commerce builds for enterprise retail.

Shopify's App Store has over 8,000 apps; BigCommerce's equivalent is considerably smaller. For standard commerce operations, this gap doesn't matter, both cover the fundamentals. Where it matters is at the edges: the specific B2B workflow your operation needs that isn't built into either platform natively. When that workflow exists as an app on Shopify, you can evaluate, trial, and deploy it without custom code. When BigCommerce doesn't have it, the path leads to custom development.

That said, BigCommerce's API quality is genuine, and for headless builds it has an established track record with enterprise retail teams that have dedicated frontend developers. Shopify Plus supports headless via Hydrogen, with Oxygen as the hosting layer. Both are viable. If your team has existing headless expertise on BigCommerce and significant custom frontend already in place, the rebuild cost is a real migration consideration. For mid-market B2B operators without a dedicated dev team, the Shopify app ecosystem wins on the practical question of how often an existing app solves your problem.

Both platforms are hosted SaaS, neither requires you to manage servers or build redundancy, and both include uptime SLAs and dedicated support at the enterprise tier. Shopify's infrastructure is tested at a scale few other platforms touch, but for a mid-market B2B operation, your traffic events will not stress either platform.

The performance conversation that matters more for B2B operators is configuration speed, not raw infrastructure scale. How quickly can your team update pricing? How fast can you configure a new company account and price list? How long does a checkout-rule change take without a developer in the loop? On Shopify Plus with native B2B, these are admin tasks. On BigCommerce, more of them require developer involvement.

If you're running B2B operations on BigCommerce and evaluating a move, the migration is well understood. Uncap has done this enough times that the variables are predictable.

A migration covers: product-catalog transfer including variants, metafields, and custom data; customer-account migration including history and pricing-tier data; order-history migration for accounting continuity; URL preservation and 301 redirects so SEO equity transfers; Shopify theme development and B2B storefront configuration; ERP integration setup; and full Shopify B2B configuration including company accounts, price lists, net terms, and checkout rules. Uncap's BigCommerce migration service uses a structured scoping process before any development starts, defining exactly what migrates, what gets rebuilt, what dependencies need resolving, and what the timeline looks like based on your catalog size and integration complexity.

BigCommerce's customer-group pricing structure does not map 1:1 to Shopify's price-list model. Customer pricing data needs to be extracted, remapped to Shopify's B2B price-list format, and validated before launch, manageable, but it requires preparation rather than a direct import.

Custom functionality built in BigCommerce using Stencil templates or custom checkout scripts needs to be rebuilt on Shopify. In most cases this is an opportunity rather than a cost: many functions that required custom BigCommerce code are handled natively on Shopify Plus or via existing apps, so the rebuild scope is usually smaller than operators expect. For a typical mid-market B2B operation, a BigCommerce to Shopify Plus migration takes 8 to 14 weeks; larger catalogs (10,000+ SKUs) and more complex ERP integrations push toward the high end.

The honest answer depends on your team, your current setup, and what you're trying to accomplish in the next 12 months.

The 2026 summary: Shopify Plus has reached feature parity with BigCommerce on native B2B for mid-market operators, and in several areas has passed it. BigCommerce is a capable platform, but its investment focus has narrowed. For most manufacturers and distributors evaluating the two from scratch in 2026, the case for Shopify Plus is stronger than it has ever been.
