BigCommerce vs Shopify for B2B

It's ready — and it's been ready since the GA in 2023. For new B2B builds and most mid-market B2B replatforms, B2B on Shopify Plus is fully competitive: Companies, Locations, Buyer Roles, Catalogs with quantity rules and price overrides, Net Terms, draft-order quoting, integrated with Shop Pay + Functions + Checkout UI Extensions. The B2B-app ecosystem (BSS B2B, Sparklayer, B2B Wave) has matured significantly. Where it still lags BigCommerce B2B Edition is: sales-rep portal depth, quote-led workflow nuances for distributor models, and some specific multi-step purchase-approval flows. For 70%+ of B2B brands, the Shopify side is now the cleaner play.

Workflow model. BigCommerce B2B Edition is built around a quote-led, sales-rep-assisted distributor model — buyers request quotes, reps respond with adjusted pricing, multi-step approvals flow through the platform natively. B2B on Shopify is built around a contracted-pricing, self-service model — buyers log in to a Company, see their catalog with their price list applied, and place orders without rep involvement (with quote workflows available when needed). If your B2B is rep-led and quote-led, BigCommerce's structural fit is closer; if your B2B is self-service contracted-price ordering, Shopify's structural fit is closer.

Both can, but Shopify's pattern is cleaner. On Shopify Plus, B2B is detected at login — a logged-in B2B buyer sees their Company catalog and B2B pricing; non-authenticated visitors see DTC. Same storefront, same theme, dual experience. On BigCommerce, the equivalent pattern is workable but more often involves Multi-Storefront (separate B2B storefront with shared catalog) for clean separation, which is structurally different. For brands that want one unified storefront with DTC + B2B layered, Shopify Plus is the more natural fit.

Both platforms integrate cleanly with the major ERPs via Celigo, Boomi, MuleSoft, or direct API. Shopify Plus's Admin GraphQL API has Plus-tier rate limits that accommodate enterprise B2B sync volume (catalog updates, contracted pricing changes, inventory sync, order push-back). BigCommerce's APIs are generally more permissive (higher rate limits, fewer gated endpoints), which can be an advantage for very high-volume integrations. For most enterprise B2B brands, both platforms handle ERP integration well — the choice usually comes down to which middleware vendor has the deeper, better-maintained connector for your specific ERP.

Highly variable. Shopify Plus B2B is included in the standard Plus price ($2,300+/month committed annual + GMV variable). BigCommerce B2B Edition is an add-on to Pro / Enterprise tiers, quoted on GMV / company-account band. For most mid-market B2B (sub $10M GMV), Shopify Plus + B2B comes in close to or slightly above BigCommerce + B2B Edition. At higher GMV with non-Shopify-Payments gateways, BigCommerce's zero transaction fees can dwarf the platform-fee difference. We model TCO at discovery.

Hydrogen has the more out-of-the-box B2B story right now — Customer Account API supports B2B login, Companies, Catalogs without additional configuration. Catalyst (Next.js) accesses B2B Edition data via the BigCommerce GraphQL API but you build more of the B2B UI yourself. For headless B2B builds, Hydrogen is currently the cleaner path; that may change as Catalyst matures. Both Shopify and BigCommerce expose GraphQL APIs that any front-end framework can consume — Hydrogen and Catalyst are the opinionated starters, not the only options.

We genuinely have no commercial reason to prefer one platform over the other — both platforms pay agency commissions on referred merchants, and we have working B2B implementations on both concurrently. We migrate brands in both directions monthly. If we recommended the wrong platform for a specific B2B model, the project would underperform and we'd lose the renewal. The whole agency depends on getting platform recommendations right, not on selling one side. That said: our experience is that for 70%+ of new B2B builds in 2026, B2B on Shopify Plus is now the cleaner play — and BigCommerce B2B Edition is the better fit for the remaining 30% (distributor models, deep quote workflows, sales-rep-heavy operations, multi-storefront B2B).

Both directions happen. BigCommerce B2B Edition → B2B on Shopify Plus is increasingly common — brands moving for Shop Pay conversion, unified DTC + B2B storefront, or modern customer-account UX. Shopify B2B → BigCommerce B2B Edition is less frequent but happens for brands needing deeper sales-rep workflows or multi-storefront B2B. Either migration is a serious replatform with 12–16 weeks of typical timeline. See /bigcommerce-to-shopify-plus-migration for the playbook.
