Shopify Plus B2B vs BigCommerce B2B Edition: Which Fits Your Wholesale Model?

Until recently, enterprise wholesale brands wanting to sell online faced an unappealing choice: spend hundreds of thousands building a heavyweight custom portal on legacy software like Magento/SAP Hybris, or attempt to hack together consumer eCommerce platforms using third-party wholesale apps and duplicate storefronts.

Today, Shopify Plus and BigCommerce have both elevated B2B into first-class citizens. Shopify integrated native B2B functionality directly into its Plus admin, while BigCommerce expanded its specialized BigCommerce B2B Edition suite.

Both platforms allow manufacturers, distributors, and hybrid D2C/B2B brands to deliver modern digital ordering experiences to commercial buyers. However, their underlying architectural philosophies differ significantly. Here is an honest, hands-on comparison of where each platform excels and how to determine which one fits your wholesale workflow.

Architectural Philosophy: Integrated vs Specialized Suite

The fundamental difference between the two platforms begins at the architecture level:

• Shopify Plus B2B: Built directly into the core Shopify platform. Wholesale buyers use the same checkout, inventory pools, and administration interface as consumer sales. There is no external app layer—B2B is managed via native "Companies", "Catalogs", and checkout extensibility.
• BigCommerce B2B Edition: Originating from BigCommerce's acquisition of BundleB2B, this is a dedicated, enterprise-grade B2B layer built on top of BigCommerce's open SaaS architecture. It provides an advanced corporate buyer portal, sales representative impersonation tools, and quote management designed specifically for complex organizational buying hierarchies.

Company Hierarchies & User Permissions

Commercial wholesale buying rarely involves a single person placing an order with a personal credit card. It involves purchasing agents, branch managers, and accounting departments with strict spend limits and approval workflows.

BigCommerce B2B Edition

BigCommerce has an edge when it comes to deep corporate structures:

• Multi-tier organizational hierarchies: Allows parent-child corporate relationships (e.g., a corporate holding company managing 50 distinct regional franchisee locations), each with separate shipping addresses and centralized invoicing.
• Granular buyer roles: Built-in roles for Junior Buyers (orders require approval), Senior Buyers (instant ordering up to budget limits), and Company Admins (manage internal users and addresses).
• Sales rep enablement: Sales reps can be assigned specific client books, log in to impersonate clients, and place orders on their behalf directly through the frontend portal.

Shopify Plus B2B

Shopify has made rapid strides with its native Company profiles:

• Company locations: A Company can have multiple locations with specific billing/shipping addresses and assigned catalogs.
• Contact permissions: Contacts can be designated as ordering agents or administrators for specific locations.
• Approval workflows: Shopify now supports purchase order submission with manager approvals directly within native checkout.
• Simplicity: Setup is exceptionally intuitive for store admins already familiar with the Shopify admin interface.

Price Lists, Volume Tiering & Catalogs

Both platforms allow you to create custom price lists and assign them to specific accounts, but they handle edge cases differently:

• BigCommerce: Supports price lists with percentage discounts, fixed price overrides, quantity breaks (e.g., 1-99 @ $50, 100+ @ $42), and custom catalog visibility. Its native integration with Enterprise ERPs makes syncing high-SKU matrix price lists seamless.
• Shopify Plus: Allows creating "Catalogs" assigned to companies. You can set percentage adjustments or fixed variant prices, define minimum and maximum order quantities, and restrict SKU visibility. Plus also supports quantity rules and incremental ordering (e.g., must buy in case packs of 12).

Quoting & Negotiation Workflows

In B2B, price negotiation is standard practice. Buyers frequently request quotes for large project quantities or contract bids.

• BigCommerce B2B Edition shines in native quoting: Buyers can convert their active cart into a formal quote request with a single click, upload custom drawings or RFQ documents, and negotiate back-and-forth with your sales team. Sales reps can adjust line pricing, apply shipping discounts, set quote expiration dates, and send the approved quote back for one-click checkout.
• Shopify Plus handles quoting via Draft Orders: While functional, quote requests on Shopify often require custom apps or manual draft order creation by internal staff unless augmented with checkout UI extensions.

Payment Terms, Invoicing & Net Accounts

Wholesale customers expect to pay on credit terms rather than upfront credit card transactions:

• Payment terms on Shopify Plus: Seamlessly configure Net-15, Net-30, Net-60, or Due on Fulfillment terms per company location. Customers receive automated invoices with embedded payment links, and admins can track outstanding accounts receivable inside Shopify admin.
• Payment methods on BigCommerce: Native support for Purchase Orders (PO), Net terms, ACH bank transfers, credit limits, and third-party B2B credit providers (like TreviPay or Balance). It also includes a dedicated buyer portal where corporate customers can review statement history and pay multiple outstanding invoices simultaneously.

Hybrid D2C + B2B vs Dedicated Wholesale

One of the biggest strategic questions is whether you plan to run both consumer retail and wholesale from the same storefront:

Blended Storefront (Same URL): If you want consumer retail traffic to see MSRP while wholesale dealers log in to see their contracted pricing, Shopify Plus makes this remarkably painless because everything shares the same theme and checkout engine. BigCommerce also supports blended stores via customer group pricing and the B2B Edition theme overlay.

Dedicated Storefronts (Multi-Storefront): If your wholesale operations require completely distinct branding, different catalogs, separate warehouse routing, or strict regional tax rules, BigCommerce's native Multi-Storefront (MSF) enables you to run multiple frontends off a single backend catalog without paying for separate platform licenses.

Summary Comparison Table

How to Decide

Choose Shopify Plus B2B if:

• You already have a high-performing D2C Shopify store and want to add wholesale ordering without spinning up a second platform.
• You value Shopify's massive ecosystem of checkout apps, marketing automations, and payment options.
• Your wholesale structure is relatively straightforward (standard price lists, Net terms, case-pack rules) rather than complex parent-child corporate franchises.

Choose BigCommerce B2B Edition if:

• You are a pure-play distributor or manufacturer where formal RFQ/quote negotiation and sales rep tooling are essential to daily deals.
• You manage complex corporate accounts with multiple branches and strict buyer authorization limits.
• You need deep Multi-Storefront (MSF) capabilities to operate distinct B2B and international storefronts from a single inventory core.
