7 Best BigCommerce Alternatives for B2B Businesses (2026)

The best BigCommerce alternatives for B2B are Elastic Path, commercetools, Adobe Commerce, Salesforce Commerce Cloud, and Shopify Plus. The right pick depends on how complex your B2B model is.

BigCommerce is a solid SaaS platform. But many B2B teams hit a ceiling: contract pricing, account hierarchies, and large catalogs start to need add-ons, apps, and workarounds.

Below, we tag each of the top BigCommerce competitors with who it's best for. You'll also get honest strengths and weaknesses for every option, including Elastic Path.

Why eCommerce Businesses Are Moving Away From BigCommerce

B2B commerce looks different in 2026. Three shifts are raising the bar for every platform:

• B2B buyers expect DTC-grade experiences: Self-service portals, account-specific catalogs, and online quoting are now baseline expectations, not differentiators.
• AI agents need structured data: Buyers and procurement tools increasingly use AI to search and order, which rewards platforms with clean, API-first catalog data.
• Finance wants total cost of ownership (TCO): Teams now count apps, integrations, and upgrade costs, not just the license fee.

That's where BigCommerce fit gets tested. The platform grew up serving DTC merchants. Its B2B features come through B2B Edition, an add-on rather than the core data model.

As a result, B2B teams often report the same pattern: plan upgrades tied to sales volume, catalog and variant limits, and a growing stack of third-party apps for quoting and approvals.

Note: This isn't a knock on quality. BigCommerce is a capable, well-supported platform with strong headless support. For many mid-market brands, it's the right call. This article is about fit for complex B2B.

7 Best BigCommerce Alternatives: A Quick Overview

Here's how the top enterprise ecommerce platforms compare at a glance.

1. Elastic Path: Best for Enterprise B2B and Complex Composable Commerce

Play Video

Elastic Path Composable Commerce was purpose-built for the complexity of B2B enterprise.

B2B is native rather than a separate edition. You get composability without funding a from-scratch build, since the storefront starter, integration layer, and B2B workflows are already in the platform.

Key Features

Three capabilities decide most evaluations for teams leaving BigCommerce: catalog and pricing control, platform extensibility, and integrations.

Product Experience Manager (PXM)

Product Experience Manager separates products, pricing, and catalogs. That gives you unlimited catalogs, hierarchies, and price books with no data duplication.

Why does that matter? Change a product once, and it updates across every catalog. No maintaining 50 copies of the same product for 50 buyer segments.

Rules-based catalogs then assign the right assortment and price book to each account, region, or channel. Your merchandisers manage that logic, not your developers.

This directly answers two common BigCommerce constraints: per-product variant limits and price-list management at scale.

Commerce Extensions

Commerce Extensions let you extend a core resource, or build a new one, through custom APIs. You never touch platform code.

For example:

• Extend an order: Attach a "warranty expiry date" and "registered owner" to the standard Order object, so the warranty travels with every purchase.
• Create a new resource: Build a "Machine Registry" that tracks which machines each customer owns, then use it to show compatible parts.

On BigCommerce, logic like this usually means an app, a middleware service, or metafield workarounds.

Composer: Integrated iPaaS

Composer is a no-code and low-code integration and orchestration layer. It includes:

• Pre-built connectors: For example, connecting Algolia search takes your API keys, not a custom build.
• Build-your-own integrations: Assemble new integrations from reusable parts.
• Health monitoring: See the status of every integration in one place.

Elastic Path also includes native Subscriptions and Entitlements, covering physical products plus digital and usage-based offers, with no third-party billing tool required.

Pro tip: If your B2B model mixes product sales with service contracts or usage-based billing, test subscriptions early in your evaluation. It's one of the areas where platforms differ most.

Where Elastic Path Shines

• Native B2B complexity: Account hierarchies, negotiated quotes, unlimited price books, and context-aware catalogs work out of the box. They aren't bolted on.
• Composable without the dev tax: You get the flexibility of a MACH stack. Composer, Commerce Extensions, and the promotions builder cut the custom development that makes pure-API platforms expensive.
• Reliability at scale: Average API response times at or under 30ms, 5M+ SKUs, 10× autoscaling in under five minutes, a 99.99% uptime SLA, and SOC 2 compliance. AI and MCP support also give agents structured access to your catalog data. Learn about intelligent commerce.

Where Elastic Path Falls Short

• Built for scale, not simplicity: If you're under roughly $100M in revenue with a simple catalog, it's more platform (and budget) than you need.
• Needs engineering capacity: Headless, composable architecture means you bring or hire developers. Implementation is a project, not a weekend migration.

Who Elastic Path Is Best For

• Enterprise B2B and B2B2C: $100M+ manufacturers, distributors, and regulated industries with complex selling models.
• Complex catalogs and pricing: Many buyer segments, price books, variations, or large SKU counts.
• Multi-brand and multi-market: Teams running multiple brands or operating in 3+ countries with regional pricing.
• Teams leaving homegrown commerce: Your custom build has become a maintenance trap.

2. commercetools: Best for Pure MACH Composable

commercetools is an API-first commerce platform and an early pioneer of MACH (microservices, API-first, cloud-native, headless) architecture. It's proven at global scale.

BigCommerce pain it solves: Architectural flexibility and scale.

Pain it doesn't: Time to launch. You build the storefront, B2B workflows, and much of the stack yourself.

Key Features

Granular Commerce APIs

Every commerce function is exposed through APIs, so engineering teams can compose exactly the stack they want.

Advanced B2B APIs

Business Units support account hierarchies through an add-on. Your developers build the buyer-facing quoting and approval workflows on top.

Where commercetools Shines

• Global scale: Proven with large, high-traffic enterprise brands.
• Maximum flexibility: You choose every component of your stack.

Where commercetools Falls Short

• Build burden: Storefront, CMS, search, and PIM are typically separate builds or vendors.
• Developer dependency: Routine business changes often need developer involvement.

Who commercetools Is Best For

• Engineering-led enterprises: Teams with a dedicated platform team and budget to assemble a best-of-breed stack.

3. Adobe Commerce (Magento): Best for Open-Source Enterprise Customization

Adobe Commerce (formerly Magento Commerce) offers a full admin, a native B2B module, and one of the largest extension marketplaces in commerce.

BigCommerce pain it solves: B2B depth and customization.

Pain it doesn't: Build cost and maintenance overhead.

Key Features

Native B2B Module

Company accounts, shared catalogs, negotiable quotes, requisition lists, and purchase orders are built in.

Adobe Experience Cloud Integration

Commerce connects to Adobe's content, analytics, and personalization tools. That's the main draw if your marketing team already runs on Adobe.

Where Adobe Commerce Shines

• Extension depth: Most features have a ready-made extension.
• Mature B2B features: Quotes and company accounts are ready to configure.

Where Adobe Commerce Falls Short

• Long, specialized builds: Projects need experienced Adobe Commerce developers.
• Upgrade overhead: Extensions and customizations add testing work at every upgrade.

Who Adobe Commerce Is Best For

• Adobe Experience Cloud customers: Teams that want commerce on the same stack as content and analytics.
• Teams with an SI partner: Organizations willing to trade launch speed for deep customization.

4. Salesforce Commerce Cloud: Best for Existing Salesforce Ecosystems

Salesforce Commerce Cloud is now sold as Agentforce Commerce, covering B2B Commerce, B2C Commerce, and Order Management.

BigCommerce pain it solves: Disconnected CRM and commerce data.

Pain it doesn't: Flexibility outside the Salesforce stack.

Key Features

Shared Data Model With Salesforce CRM

B2B Commerce runs on the core Salesforce platform. Sales reps and self-service buyers see the same account, pricing, and quotes.

Agentforce AI Agents

AI agents for shoppers, buyers, and merchants come built in.

Where Salesforce Commerce Cloud Shines

• One ecosystem: Commerce, CRM, service, and marketing share data.
• Global scale: Strong multi-site support for large operations.

Where Salesforce Commerce Cloud Falls Short

• Partner-heavy implementations: Most projects need specialized Salesforce partners.
• Ecosystem lock-in: Value drops when you work outside Salesforce.

Who Salesforce Commerce Cloud Is Best For

• Salesforce-centric enterprises: Teams that want commerce on the same data model as their CRM.

5. Shopify Plus: Best for DTC-Led Brands and Simpler B2B

Shopify Plus is Shopify's enterprise tier. It trades architectural control for speed, a polished admin, and the largest app ecosystem in commerce.

BigCommerce pain it solves: Speed to launch and app availability.

Pain it doesn't: Complex B2B pricing, catalogs, and account structures.

Key Features

Native B2B on Plus

Company profiles, customer-specific catalogs, and payment terms cover straightforward wholesale alongside DTC.

Hydrogen and Oxygen

Hydrogen is Shopify's React-based headless framework. Oxygen hosts it.

Where Shopify Plus Shines

• Speed to market: Launch in weeks.
• App ecosystem: Most features are an install away.

Where Shopify Plus Falls Short

• B2B ceiling: Deep contract pricing and multi-level accounts can outgrow it.
• Less control: You work within Shopify's data model and checkout.

Who Shopify Plus Is Best For

• DTC-led brands: Consumer businesses where wholesale is the simpler channel.

6. Shopware: Best for Open-Source B2B

Shopware is an open-source commerce platform with a strong European presence and a B2B Components extension for company accounts, quotes, and approvals.

It solves BigCommerce's flexibility and ownership pain, since you can access and modify the code. It doesn't remove the need for technical resources to configure, host, and maintain it.

Best for: Mid-market B2B sellers, especially in Europe, that want open-source control.

7. Swell: Best for Mid-Market Subscriptions and Headless

Swell is a headless SaaS platform with native subscriptions and flexible product modeling. It solves the subscription-app pain many BigCommerce merchants run into.

It's not built for deep enterprise B2B, like multi-level accounts or large distributor networks.

Best for: Mid-market brands that want headless with subscriptions built in.

Reasons to Consider an Alternative to BigCommerce

BigCommerce is a capable platform. But four specific gaps push B2B and enterprise teams to look at other composable commerce platforms.

B2B Is a Bolt-On, Not Native

BigCommerce grew up in DTC. Its B2B features come through B2B Edition, an add-on [verify: availability by plan and starting price].

Teams with custom quotes, contract pricing, punchout catalogs, and multi-step approvals often find the DTC roots show quickly.

How Elastic Path handles it: Account hierarchies, negotiated pricing, and context-aware catalogs are native. See our guide to commerce architecture built for B2B.

Revenue-Based Pricing and Forced Plan Jumps

BigCommerce ties its standard plan tiers to online sales thresholds. Growth can trigger an upgrade, and costs rise with it.

How Elastic Path handles it: Pricing is structured around GMV or order volume on multi-year enterprise terms. That makes costs predictable at scale for the right-sized business.

Catalog, Variant, and Pricing-Model Limits

BigCommerce caps variants per product. Price lists and variant reporting can also make multi-segment B2B pricing hard to manage.

How Elastic Path handles it: Product Experience Manager separates pricing, products, and catalogs. You get unlimited catalogs and price books with no data duplication.

App Dependency, TCO, and Scale

Advanced B2B functions, like quoting through apps such as B2B Ninja, often rely on third-party tools. Each one adds cost, another vendor, and another failure point.

How Elastic Path handles it: Core B2B is native. It's backed by average API responses at or under 30ms and a 99.99% SLA. Learn more about Elastic Path's platform architecture.

Match the Platform to Your Complexity With Elastic Path

Your next step depends on your business. If you're a $100M+ B2B seller with complex catalogs, pricing, or account structures, Elastic Path is the composable, native-B2B choice.

If you're smaller or simpler, start with Shopify Plus for DTC speed or Swell for headless subscriptions. If you want pure MACH and have a platform team, look at commercetools.
