TL;DR

Both platforms run serious B2B in production. BigCommerce B2B Edition (GA 2018) fits quote-led, sales-rep-assisted distributor models with deep approval chains, Quick Order surfaces, and Sales Buyer Portal. B2B on Shopify Plus(GA 2023+) fits self-service contracted-pricing B2B, unified DTC + B2B storefronts, and modern customer-account UX — and is now the cleaner play for ~70% of new B2B builds. The deciding factor is your workflow model (quote-led vs self-service) more than feature parity. We're a Shopify Plus Partner + Elite BigCommerce Partner with working B2B implementations on both.

Decision Framework

The Question That Settles It

For most B2B platform decisions, the deciding factor isn't feature parity — it's workflow model. The five questions below get to the workflow answer in under 10 minutes.

1. Quote-led or self-service?

Buyers mostly request quotes that reps respond to — BigCommerce B2B Edition. Buyers mostly self-serve with their contracted catalog — B2B on Shopify Plus.

2. DTC + B2B unified or split?

One storefront with B2B detected at login — Shopify Plus. Separate B2B storefront with shared catalog — BigCommerce Multi-Storefront.

3. Sales-rep heavy?

Reps order on behalf of accounts daily — BigCommerce B2B Edition (Sales Buyer Portal is native). Shopify supports this via apps (BSS, Sparklayer) but it's not first-party.

4. Customer-account UX modernization a priority?

Shopify Plus — Customer Account API and B2B UI are visibly more modern. Matters when modernizing from a legacy distributor portal.

5. Headless B2B?

Hydrogen currently has the cleaner out-of-the-box B2B story via Customer Account API. Catalyst (BigCommerce + Next.js) supports B2B but requires more custom UI build.

6. Open Checkout customization critical?

BigCommerce — Open Checkout (forked React) is the deepest checkout-customization surface in commerce. Matters for bespoke PO / invoice / approval flows in checkout.

B2B Workflow Notes

Where the Real Differences Show Up

The feature matrix above lists capabilities. The workflow nuances below are where the choice actually lands.

Companies & buyer hierarchies

Both platforms model B2B as Companies with multiple Locations / Sub-accounts and Buyer Roles. Shopify's role surface is simpler (Buyer, Catalog Editor, Location Admin); BigCommerce's is richer (Junior Buyer, Senior Buyer, Account Owner, Sales Rep visibility). For straightforward DTC + B2B, Shopify's simpler model is easier to administer; for complex distributor hierarchies with budget controls and purchase approvals, BigCommerce's deeper role model fits more naturally.

Price lists & catalog overrides

Both platforms support per-company catalog assignment + percentage / fixed price overrides. Shopify B2B Catalogs are admin-friendly and bulk-editable; BigCommerce Price Lists have richer date-range scheduling and per-quantity-break pricing. Both support CSV import for bulk price updates. For brands with ~100s of customer-group prices, both platforms scale; for brands with 10K+ contracted prices, the ERP-sync pattern matters more than the admin UI.

Quote workflows

Shopify's native draft-order quoting is a sales-team-driven flow — rep creates the quote in admin, buyer pays via a checkout link. Adequate for most B2B use cases. BigCommerce's B2B Edition quoting is more buyer-driven — buyer requests quote from PDP, sales rep responds with adjusted pricing, multi-step approval flows are native. For distributor models where quote-led purchasing is the dominant pattern, BigCommerce is structurally closer to the workflow.

ERP integration patterns

Both platforms integrate with NetSuite, SAP, Microsoft Dynamics, Acumatica, Sage via middleware (Celigo, Boomi, MuleSoft) or direct API. Shopify Admin GraphQL has stricter rate limits at non-Plus tiers; Plus rate limits accommodate enterprise B2B volume. BigCommerce's APIs are generally more permissive for 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 connector for your specific ERP.

When to Pick Each

The Concrete Recommendations

Pick BigCommerce B2B Edition if

BigCommerce B2B Edition

Heavy distributor or wholesale model with deep quoting / approval / requisition-list workflows — BigCommerce B2B Edition has been in market since 2018 and has the most mature workflow surface for these patterns.
Quick Order surface is central to the buyer experience — BigCommerce's Quick Order with SKU search, CSV upload, and saved-order templates is more configurable than the Shopify-native equivalent.
Sales-Rep Portal critical — BigCommerce B2B Edition's sales-rep portal (Sales Buyer Portal) lets reps order on behalf of accounts with full account-level visibility. Shopify has equivalent flows via B2B apps (BSS, Sparklayer) but not as native.
Multi-storefront B2B (separate themes / domains for different buyer segments with shared catalog and inventory) — BigCommerce Multi-Storefront handles this natively in one backend.
Total checkout source control needed for bespoke PO / invoice / approval flows — Open Checkout (forked React) gives you the deepest checkout customization in commerce, which matters for B2B-specific checkout patterns Shopify Checkout Extensibility can't fully express.
Zero transaction fees at high B2B GMV — for distributors processing millions in invoice / ACH / wire / Net-30 transactions, BigCommerce's no-transaction-fee model can dwarf the platform-fee difference.

BigCommerce Enterprise → BigCommerce Experts →

Pick B2B on Shopify Plus if

B2B on Shopify Plus

DTC + B2B unified storefront — Shopify Plus lets you run consumer and B2B businesses on one storefront with B2B detected at login (Companies, Catalogs, Net Terms) and DTC for non-authenticated visitors. Cleaner than maintaining a separate B2B storefront.
B2B-on-Shopify is GA since 2023 and tightly integrated with the rest of Shopify Plus — Shop Pay, Functions, Checkout UI Extensions, Markets, Hydrogen all play with B2B as a first-class citizen.
Modern UX expectations — B2B on Shopify's customer-account UI, Companies / Locations / Buyer Roles UI, and Catalogs admin are visibly more modern and faster than BigCommerce B2B Edition's. For brands modernizing from a legacy distributor portal, the UX delta matters.
Strong B2B app marketplace — BSS B2B, Sparklayer, B2B Wave, Wholesale Pricing, Bold Custom Pricing all have deep Shopify integrations. The B2B app ecosystem on Shopify has matured significantly post-2023.
Headless B2B via Hydrogen — first-party React + Remix storefront with Customer Account API supports B2B login flow and Companies / Catalogs out of the box. Cleaner B2B headless story than BigCommerce + Catalyst (which has B2B support, but less integrated).
ERP integration via Shopify Admin GraphQL — modern, well-documented GraphQL API for syncing NetSuite, SAP, Microsoft Dynamics, and Acumatica catalog / pricing / inventory / order data. Plus-tier rate limits accommodate enterprise B2B integration volume.

FAQ

BigCommerce vs Shopify for B2B FAQs

Is B2B on Shopify ready for serious B2B businesses, or is it still catching up?

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.

What's the most important difference between the two for B2B?

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.

Can either platform run DTC and B2B on the same storefront?

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.

What about ERP integration — NetSuite, SAP, Dynamics?

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.

Pricing — which is more expensive for B2B?

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.

Headless B2B — Hydrogen or Catalyst?

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.

Are you really unbiased? You're a Shopify Plus Partner AND a BigCommerce Elite Partner.

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).

What about migration between them for B2B brands?

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.
