Shopify Plus vs BigCommerce for B2B eCommerce

Shopify Plus and BigCommerce are the two leading SaaS platforms for mid-market B2B eCommerce — and the real difference is where B2B lives. On Shopify Plus, company accounts, catalogs, price lists, and payment terms are native to the core admin. On BigCommerce, they arrive through B2B Edition, a capable application layer on top of the platform, backed by very open APIs.

We've shipped production B2B on both: Atelier du Chef on BigCommerce with a deep SAP ERP integration, and 50+ B2B storefronts on Shopify Plus. This comparison is written from that build experience — not to declare a winner, but to match each platform to the scenarios where it earns its keep.

HEAD TO HEAD

How do Shopify Plus and BigCommerce compare for B2B?

Dimension Shopify Plus BigCommerce (B2B Edition)
Where B2B lives Native — Company Accounts, Catalogs, Price Lists, Payment Terms, B2B Checkout inside the core admin B2B Edition — a capable application layer bundled on top of the core platform, with parts of its own interface
Platform pricing Flat — $2,300–$2,500 USD/month, predictable as you scale Negotiated Enterprise pricing, tiered against sales volume — can be cheaper at lower GMV
Total cost of ownership Native B2B typically replaces 4–8 paid apps for wholesale merchants App stack plus custom development often carries the B2B feature load
Checkout extensibility Shopify Functions — sandboxed, versioned, platform-managed Open checkout with direct code access — maximum control, you own the maintenance
API openness Broad APIs within an opinionated platform architecture Very open APIs, fewer platform constraints — a genuine strength for custom builds
ERP integration Patchworks iPaaS, established apps, or custom middleware Typically custom API integration — proven in production (we built BigCommerce + SAP)
App ecosystem The largest commerce app ecosystem — most gaps have an app answer Smaller ecosystem — gaps more often resolved with custom development
Partner ecosystem Deep bench of B2B-capable agencies and developers in North America and Europe Thinner partner pool, especially for complex B2B implementations
Platform velocity Major B2B improvements shipping quarterly Steady but slower cadence on B2B-specific capability

Neither column is a knockout. The table reads differently depending on your revenue band, your integration landscape, and whether your team builds or buys — which is why the next two sections are scenario-based.

SCENARIOS · OPEN PLATFORM

When is BigCommerce the right choice?

We built Atelier du Chef — a commercial kitchen equipment distributor with account-based pricing fed live from SAP — on BigCommerce, and it runs as one system with the ERP. That project taught us where the platform genuinely earns its place:

  • A stable custom ERP integration already in production — If BigCommerce and your ERP already operate as one system, rebuilding that integration elsewhere is a real cost. Working infrastructure deserves more respect than platform fashion.
  • Open code-level control — BigCommerce's open checkout and very open APIs suit teams with in-house developers who want to own their storefront and integration logic outright, without platform guardrails.
  • Multi-storefront on a tighter budget — Running several branded storefronts from one backend is available without stepping up to enterprise-tier pricing.
  • Lower platform cost at lower volume — At smaller B2B revenue bands with a lean app stack, negotiated BigCommerce pricing can undercut the Shopify Plus flat fee.

SCENARIOS · NATIVE B2B

When is Shopify Plus the right choice?

  • You want B2B native, not layered — Company Accounts, Catalogs, Price Lists, Quantity Rules, and Payment Terms live in the core admin. No separate B2B interface, no app dependency for the fundamentals.
  • Hybrid B2B + DTC from one admin — Wholesale and retail run from one storefront, one inventory, one team. This is where the native architecture pays off daily.
  • Your app stack is doing B2B's job — If you're paying for 4–8 apps to deliver what Shopify ships natively, the TCO math usually favors Plus over a three-year horizon.
  • Ecosystem depth matters — More B2B-capable agencies, more apps, and established ERP middleware like Patchworks iPaaS mean fewer problems that require custom code.
  • You're betting on platform velocity — Shopify ships major B2B improvements quarterly. If you'd rather inherit capability than build it, that cadence compounds.

For most mid-market manufacturers and distributors we work with, native B2B plus ecosystem depth is the deciding factor. But "most" is not "all" — which is exactly why we scope before we recommend.

REPLATFORMING

What does a BigCommerce → Shopify Plus migration involve?

If the scenario analysis lands on Shopify Plus, the move itself is a 12–20 week, five-phase project: discovery and readiness assessment, build and integration, data migration and QA, soft launch with selected accounts, then full cutover and decommission. B2B company accounts, customer groups, and price lists map to Shopify's native structures; the ERP integration is re-established as its own workstream; and a complete 301 redirect map protects SEO equity through the transition.

FAQ

Frequently asked questions

Is BigCommerce B2B Edition good enough for wholesale operations?
Yes — for many wholesale operations it is genuinely capable, and we say that as an agency that built one. Atelier du Chef, a commercial kitchen equipment distributor, runs on BigCommerce with account-based access, customer-specific pricing pulled live from SAP, and orders flowing straight into the ERP. B2B Edition covers company accounts, buyer roles, shared shopping lists, and quote workflows well. The honest caveat is architectural: B2B Edition is an application layer on top of the core platform rather than a native part of it, so some B2B settings live in a separate interface from the main store admin, and deeper customization tends to become custom development sooner than it does on Shopify Plus. If your B2B requirements are standard and your integration is solid, B2B Edition is not the weak point some comparison pages claim it is.
Is Shopify Plus or BigCommerce cheaper for B2B?
It depends on your revenue band and how much of your B2B capability comes from apps. Shopify Plus runs $2,300–$2,500 USD per month on flat platform pricing. BigCommerce Enterprise pricing is negotiated and tiered against sales volume, which can undercut Plus at lower volumes and converge with it as you grow. The bigger driver is total cost of ownership: on BigCommerce, B2B merchants often carry several paid apps plus custom development to fill feature gaps, while Shopify Plus covers company accounts, catalogs, price lists, and payment terms natively. In our migration work, merchants replacing four to eight paid apps with native features are the ones who see meaningful TCO reductions over a three-year horizon. At smaller B2B volumes with a lean app stack, BigCommerce can remain the cheaper platform. Run the comparison on your numbers, not on vendor calculators.
Can BigCommerce integrate with an ERP like SAP?
Yes — we have done it in production. For Atelier du Chef we built a deep integration between BigCommerce and SAP: product data, inventory across multiple locations, customer-specific pricing, and order flow all sync between the two systems, so the storefront and the back office operate as one. When a buyer places an order online, it flows directly into SAP for fulfillment with no manual re-entry. The difference between the platforms is not whether ERP integration is possible — it is how you get there. BigCommerce integrations are typically custom API builds, which gives you full control but means you own the middleware. On Shopify Plus, the same connections can run through Patchworks iPaaS, established apps, or custom middleware, so there are more pre-built paths. Either way, scope the ERP integration as its own workstream — that is where budgets slip.
When should I choose BigCommerce over Shopify Plus?
Choose BigCommerce when its architecture matches how your team works. It is a strong fit if you want open, code-level access to checkout and storefront logic without platform guardrails, if you need multi-storefront capability at a lower price tier, or if you already run a stable, custom ERP integration on BigCommerce that would cost real money to rebuild — replatforming away from working infrastructure needs a stronger reason than platform preference. It also suits teams with in-house developers who prefer owning their integration code outright. Where the calculus shifts toward Shopify Plus: when your B2B feature needs are covered natively, when you want one admin for hybrid B2B and DTC, or when you depend on a deep partner and app ecosystem instead of custom builds. We recommend per scenario, not per platform — the discovery call exists to figure out which one you are in.
How hard is it to migrate from BigCommerce to Shopify Plus later?
It is a well-trodden path — a typical mid-market migration with B2B operations runs 12–20 weeks from discovery to full launch. BigCommerce company accounts, customer groups, and price lists map to Shopify’s Company Accounts, Catalogs, and Price Lists, and most merchants retire 30–50% of their paid app stack by leveraging native features. The workstreams that need real planning are the ERP integration, which gets re-established rather than copied, and SEO, which needs a complete 301 redirect map covering products, categories, and content before cutover. Order history, customer data, and B2B account structures migrate on established patterns with validation at each step.
