Top BigCommerce B2B Themes to Boost Online Success

BigCommerce has become a leading choice for B2B brands building online storefronts. Its B2B Edition, native multi-storefront capabilities, and flexible theme architecture make it particularly well-suited for wholesalers, distributors, and manufacturers who need more than a standard retail template. The right theme does more than determine how a site looks: it shapes the entire buying experience for B2B customers, including how they browse catalogs, manage accounts, place bulk orders, and pay invoices.

B2B eCommerce is no longer just about putting a catalog online. B2B buyers in 2025 expect self-service capabilities comparable to the consumer apps they use daily: easy reordering, transparent pricing, account visibility, and fast checkout. The themes below are designed with those expectations in mind.

Here are the top BigCommerce themes for B2B merchants.

1. Cornerstone

Cornerstone is BigCommerce’s flagship theme and the foundation of the platform’s Stencil theme framework. It is free, actively maintained by BigCommerce, and designed to adapt to virtually any industry or vertical. For B2B merchants, its relevance comes from its flexibility rather than B2B-specific features.

Key features include multiple homepage layout options, a customizable checkout experience, advanced quick view on product pages, and saved payment methods for returning buyers. The theme is fully responsive and follows mobile-first design principles, ensuring a consistent experience across devices.

Because Cornerstone is BigCommerce’s reference theme, it serves as the best starting point for merchants who plan to implement BigCommerce B2B Edition features. All B2B Edition capabilities, including the Buyer Portal, delegated purchasing, and invoice management, are designed to overlay on top of Stencil-based themes like Cornerstone. For merchants working with a BigCommerce development agency, Cornerstone is also the easiest base from which to build custom B2B extensions and custom checkout logic.

2. Camden B2B

Camden is one of the most purpose-built B2B themes in the BigCommerce theme marketplace. It is designed specifically for merchants who need to manage complex account structures and B2B purchasing workflows directly from the storefront.

Key features include:

• Adding items by SKU number for buyers who know exactly what they need without browsing
• Login-protected catalogs that restrict product visibility to authenticated account holders
• Shopping list management for recurring or project-based purchases
• Customer personalization and account-based display preferences
• A switchable grid/list view to match different buyer browsing preferences
• Persistent mini cart, contextual navigation, and configurable tax display
• An improved account area for B2B buyers managing orders, invoices, and shipping addresses

Camden’s login-protected catalog functionality is particularly valuable for manufacturers and distributors who sell to different customer tiers at different price points and do not want anonymous visitors to see customer-specific pricing or restricted product lines. This feature aligns with how SuiteCommerce Advanced handles customer-specific catalog visibility natively, making Camden a strong theme choice for BigCommerce implementations that need to replicate the account-gated experience that B2B buyers expect.

3. Supermarket Modern

Supermarket Modern is a theme optimized for high-SKU wholesale operations. Its design prioritizes efficient catalog navigation and bulk ordering, which are the two primary buying behaviors of wholesale B2B customers.

Key features include:

• Bulk order capabilities for entering multiple items and quantities simultaneously
• Category-specific product search, allowing buyers to search within a department or product line rather than across the entire catalog
• Frequently Bought Together suggestions to support cross-selling in a wholesale context
• A vertical categories menu for efficient navigation of large catalogs
• A brands list for distributors selling products from multiple manufacturers
• Google rich snippets support for improved organic search visibility

Supermarket Modern is best suited for merchants with catalogs exceeding several thousand SKUs where navigation efficiency is more important than visual merchandising. Its design philosophy prioritizes finding and ordering over discovery and inspiration, which matches the behavior of a returning wholesale buyer who knows their product range and wants to complete an order quickly rather than browse.

4. Parts Warehouse

Parts Warehouse is designed specifically for industrial wholesale and replacement parts operations. If your B2B catalog is organized around compatibility, part numbers, or fitment data, this theme is built for that structure.

Key features include:

• Large catalog management with efficient filtering and search
• Bulk order forms for high-volume purchasing
• Easy-to-navigate product catalog structures designed for parts lookup
• Features tailored to buyers placing frequent large orders

Parts Warehouse is particularly strong for NetSuite merchants in the industrial, MRO (maintenance, repair, and operations), or automotive aftermarket sectors, where buyers search by part number or specification rather than browsing by category. For merchants using Tavano Team’s BigCommerce NetSuite integration, the combination of Parts Warehouse’s product lookup UX and NetSuite’s real-time inventory and pricing sync creates a self-service ordering experience that reduces inbound sales rep calls significantly.

Choosing the Right Theme for Your B2B Store

Theme selection for B2B is a business decision before it is a design decision. The right starting point depends on three factors:

Catalog size and structure. Merchants with under 1,000 SKUs in clearly defined categories have more flexibility. Merchants with large, flat catalogs organized by part number or SKU benefit from themes like Supermarket Modern or Parts Warehouse that are built around lookup and bulk entry.

Account complexity. If your business model requires login-gated pricing, customer-specific catalogs, or multi-user company accounts, Camden is the natural starting point because those features are built into its architecture rather than layered on after the fact.

Customization roadmap. If you plan to build custom extensions or significantly modify the theme’s frontend behavior, starting with Cornerstone gives your development team the most flexibility and the most documentation support.

All four themes above are compatible with BigCommerce B2B Edition, which adds the Invoice Portal, delegated purchasing, quote management, and the Buyer Portal on top of whatever theme you choose. For merchants running NetSuite alongside BigCommerce, Tavano Team’s BigCommerce NetSuite integration connects ERP data directly to your storefront regardless of which theme you select.
