Best BigCommerce Alternatives for B2B Businesses (2026)

Key Takeaways

• Elastic Path: the strongest BigCommerce B2B alternative for enterprise B2B and complex commerce. If you're running $100M+ in revenue with account hierarchies, negotiated pricing, and multiple storefronts, this is where native B2B beats BigCommerce's bolt-on B2B Edition.
• commercetools: best for pure MACH composable commerce, if you have a strong engineering team ready to build every layer of your stack yourself.
• Adobe Commerce: best for open-source enterprise customization, for teams with deep PHP expertise who want full control over the codebase.
• Salesforce Commerce Cloud: best for brands already living in the Salesforce ecosystem.
• Shopify Plus: best for D2C-led brands adding a simpler B2B motion. Native B2B tools now ship across most Shopify plans, not just Plus.
• Shopware: best for open-source B2B, particularly for European mid-market merchants.

Introduction

Outgrowing BigCommerce usually starts in the same place: the B2B Edition. What started as an add-on for wholesale features starts to feel like exactly that, an add-on, not a foundation.

This guide breaks down seven BigCommerce alternatives honestly, including who each one serves best, where they shine, and where they fall short. No platform here is a universal answer, so we'll help you match the tool to your complexity instead.

Why eCommerce Businesses Are Moving Away from BigCommerce

B2B buyers now expect the same self-service experience they get as consumers. For a distributor, that means logging in to see their negotiated pricing automatically, reordering in a few clicks, and placing an order without a phone call or email to a sales rep.

BigCommerce is a capable SaaS platform for mid-market brands that need a fast launch and a broad set of native features. The cracks appear as complexity grows. Its B2B Edition is an Enterprise-only add-on layered onto an architecture designed for retail-first, single-catalog selling, and that foundation creates real structural limits:

• B2B and B2C don't share a backend. The B2B Edition runs as an add-on alongside the standard platform rather than inside a single, unified backend. Teams end up managing two systems for one business, which adds overhead and limits how well hybrid B2B2C models actually work.
• One catalog per instance. BigCommerce can't run multiple catalog hierarchies inside a single instance. Brands selling across regions, brands, or business lines end up standing up separate stores for each, multiplying complexity and fragmenting data.
• A rigid, thin product data model. A roughly 600-variant product limit and no first-class support for SKU-level metadata or dynamic bundles make complex catalogs and multi-segment B2B pricing hard to model and maintain.
• App-marketplace dependency. Core B2B functions like quoting often rely on third-party marketplace apps, which add cost and another point of failure.

None of this makes BigCommerce a bad platform. It's a strong choice for small-business and mid-market DTC sellers with a single, straightforward catalog. It's the B2B ceiling, specifically, that pushes buyers toward enterprise eCommerce platforms and true composable commerce platforms instead.

Best BigCommerce Alternatives: A Quick Overview

Here's how these seven BigCommerce competitors stack up on architecture and B2B readiness.

A traditional monolith like Salesforce Commerce Cloud ties the front end and back end tightly together. A retrofitted headless platform, like Adobe Commerce or Shopify Plus, bolts an API layer onto that same kind of core, which frees up the front end but leaves backend customization just as slow. Composable, API-first platforms like Elastic Path decouple every layer, so catalog, pricing, and checkout can each change independently.

1. Elastic Path: Best for Complex Enterprise B2B Use Cases

Shopify serves small business. Elastic Path serves the complexity of B2B enterprise.

Elastic Path’s API-first commerce gives you native B2B features, not BigCommerce's bolt-on version, and delivers a ready-to-use platform with composable flexibility without the heavy custom-development cost that a pure MACH build like commercetools often demands.

Key Features

Three capabilities tend to decide the build-vs-buy conversation for enterprise B2B teams: catalog and pricing management, extensibility, and integration.

Product Experience Manager (PXM)

Product Experience Manager decouples pricing, products, and catalogs from one another. That means unlimited catalogs, hierarchies, and price books with no data duplication. Change a price once, and it propagates everywhere.

This directly answers the catalog constraints that push B2B sellers off BigCommerce. See how PXM simplifies product imports.

That same clean data model matters beyond the storefront, too. PXM structures catalogs, pricing, and hierarchies into standards-aligned, API-first data (including AGNTCY-aligned outputs), so LLMs and AI agentic search engines can read a catalog programmatically instead of scraping a page.

Commerce Extensions

Commerce Extensions let you define a custom data model once, and the platform automatically generates the APIs to create, read, update, and delete it, natively, with no side database to maintain.

A distributor selling serialized equipment can track which serial numbers belong to which account and tie warranty enrollment to the order automatically. A manufacturer with a multi-step approval process can define custom order sub-statuses, like "awaiting inventory confirmation," so every system checking on an order sees its true state.

Composer: Integrated iPaaS

Composer is a no-code and low-code integration and orchestration layer, with pre-built connectors, the ability to build your own from reusable parts, and health monitoring across every integration.

Side note: Elastic Path also offers a native Subscriptions and Entitlements module covering physical and digital or usage-based billing, built into the platform rather than bolted on through a third-party app.

Where Elastic Path Shines

• Native features that serve B2B complexity: Account hierarchies, negotiated quotes, unlimited price books, and context-aware catalogs work out of the box, not bolted on.
• Composable without the dev tax: Composer, Commerce Extensions, and the promotions builder cut down the custom-development burden that makes a platform like commercetools expensive to run.
• Built for scale: Elastic Path's architecture is Kubernetes-based and auto-scaling, with a published 99.99% uptime SLA and sub-100ms average API response time, and SOC 2 Type II compliant.

Where Elastic Path Falls Short

• Built for scale, not simplicity. If you're under roughly $100 million in revenue with a simple catalog, Elastic Path is more platform than you need.
• Needs engineering capacity. Headless and composable architecture means you bring or hire developers. Elastic Path is building AI into that implementation process, though, shortening development timelines to just a few months.

Customer Case Studies

Johnstone Supply, the largest HVAC/R wholesale distributor in the U.S., runs a catalog of over a million SKUs across 450-plus stores on Elastic Path, powering roughly $2 billion in revenue. Its Director of Business Systems and Delivery said the platform lets the team keep "iterating, testing, and improving" without a full replatform every few years.

Orgill, the fastest-growing independent hardware distributor, uses Elastic Path to run a B2B2C program across more than 13,000 retail hardware stores in 50 countries. Its eCommerce director said composable commerce was "the only way to bring this program to life."

Who Elastic Path Is Best For

• Enterprise B2B and B2B2C: $100M+ revenue businesses with complex selling models, including distributor networks, manufacturers, and regulated industries.
• Complex catalogs and pricing: Many segments, price books, variations, or large SKU counts.
• Multi-brand and multi-market operations: Global businesses selling across three or more countries.
• Teams migrating off homegrown commerce: Custom builds that have become a maintenance burden.

2. commercetools: Best for Pure MACH Composable

commercetools is one of the platforms that pioneered the MACH (microservices, API-first, cloud-native, headless) approach to commerce. It's a purely headless, API-only platform, so there's no storefront or CMS included out of the box.

Where commercetools Shines

• True MACH architecture: Every service is independently deployable, giving engineering teams maximum control over the stack.
• Proven enterprise scale: Large, well-known global brands run commercetools for complex, multi-region catalogs.

Where commercetools Falls Short

• No front end included: You're building the storefront from scratch.
• DIY orchestration: commercetools ships no built-in commerce iPaaS, so teams are typically handed provisioned instances and APIs, then left to build and monitor their own integration layer. The marketplace lists partner connectors but doesn't provide native code or support for them. See a full Elastic Path vs. commercetools comparison.

On G2, commercetools rates well for product direction and support quality, though from a small review sample. Reviewers cite flexibility for complex catalogs alongside a steep learning curve.

Who commercetools Is Best For

• Large enterprises with dedicated engineering teams that want to own every layer of the commerce stack.
• Organizations already committed to a from-scratch, fully custom front end.

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

Adobe Commerce, built on the same codebase as the free Magento Open Source edition, is the go-to for teams that want deep customization and already have PHP development expertise in-house. Its native B2B module covers company accounts, shared catalogs, negotiated quotes, purchase orders, and requisition lists.

Where Adobe Commerce Shines

• Deep customization: Shared Magento roots mean a large developer talent pool and extension marketplace.
• Native B2B depth: Adobe Commerce includes company accounts and shared catalogs natively, not through apps.

Where Adobe Commerce Falls Short

• Retrofitted, not natively headless. Adobe Commerce bolts an API layer onto a tightly coupled monolithic core, so backend and frontend changes still ripple into each other, and adding new capability often means custom development rather than configuration.
• Specialized skill requirement, with a reliability tradeoff. You need PHP and Magento architecture expertise, and because the core is tightly coupled, a single failure or heavy customization can affect the whole site. Compare this against other platforms in our eCommerce platform comparison, or see a direct Adobe Commerce alternative breakdown.

Adobe Commerce sits around 4 out of 5 on G2 from a large review base. Reviewers praise its customization depth, while some note the learning curve and cost can be steep for smaller teams.

Who Adobe Commerce Is Best For

• Mid-market to enterprise B2C and B2B brands with in-house or agency PHP expertise.
• Teams needing deep, code-level customization beyond what a SaaS platform allows.

4. Salesforce Commerce Cloud: Best for Existing Salesforce Ecosystems

Salesforce Commerce Cloud (formerly Demandware) is a monolithic SaaS platform with dedicated B2C and B2B editions, built to tie tightly into the rest of the Salesforce stack, including Sales Cloud, Service Cloud, and Marketing Cloud.

Where Salesforce Commerce Cloud Shines

• Native Salesforce integration: If Sales Cloud or Service Cloud already run your business, Commerce Cloud slots in with less integration work than a third-party platform.
• Built-in AI personalization: Einstein powers recommendations, search, and merchandising out of the box.

Where Salesforce Commerce Cloud Falls Short

• Hard to run strong B2B and B2C on one instance. Reviewers consistently note that pushing both channels hard on a single Commerce Cloud deployment tends to leave one weaker, and brands with multiple catalog hierarchies often end up provisioning separate instances to compensate.
• Heavy implementation partner reliance. Integrating anything outside the Salesforce ecosystem tends to require specialized architects. See a full Salesforce Commerce Cloud comparison for the details.

Salesforce Commerce Cloud rates around 4.3 out of 5 on G2, among the highest review volumes in this category. Reviewers highlight strong product recommendations and reporting.

Who Salesforce Commerce Cloud Is Best For

• Brands already running on Salesforce for sales, service, or marketing.
• Enterprise B2B and B2C teams that value native AI personalization.

5. Shopify Plus: Best for D2C-Led Brands & Simpler B2B

Shopify Plus is the enterprise tier of Shopify, typically adopted by merchants doing $1 million-plus in annual GMV who want DTC-grade ease of use with a growing set of native B2B tools. As of 2026, core B2B functionality is no longer Plus-exclusive; it's available across Shopify's Basic, Grow, and Advanced plans too.

Where Shopify Plus Shines

• Fast time to launch: Implementations commonly complete in four to eight weeks, dramatically faster than composable alternatives.
• Genuinely easy to use: Consistently among the highest-rated platforms for ease of use and setup.

Where Shopify Plus Falls Short

• B2B depth has limits. Complex account hierarchies and heavily negotiated contract pricing often outgrow native Shopify B2B.
• App-dependent, with real tradeoffs. Deeper subscription, ERP, or quoting functionality often requires third-party apps, and stacking many at once can start to slow page speed. Shopify also still enforces fixed URL patterns, like a mandatory /products/ and /collections/ prefix, limiting full control over site architecture. Read more on headless commerce platforms or see a direct Shopify alternative comparison.

Shopify Plus rates around 4.4 out of 5 on G2, one of the largest review bases in the category. Reviewers consistently praise ease of use and reliability at scale.

Who Shopify Plus Is Best For

• D2C-led brands adding a straightforward B2B or wholesale channel alongside their consumer storefront.
• Teams that prioritize speed to launch over deep architectural customization.

6. Shopware: Best for Open-Source B2B

Shopware pairs a free, open-source Community Edition with paid tiers that add native B2B components, including quote management, customer-specific pricing, and approval workflows. It's especially strong for European mid-market B2B. Where it falls short: most B2B depth lives in the higher paid tiers, and total cost of ownership includes real agency and hosting spend on top of the license.

7. Swell: Best for Mid-Market Subscription & Headless

Swell is an API-first, headless platform built around native subscription billing, multi-currency support, and flexible product modeling, suited to mid-market brands building custom storefronts with React, Next.js, or Vue. Where it falls short: like other headless platforms, it requires developer resources to build and maintain the front end, and its B2B feature depth is less mature than platforms built B2B-first.

Reasons to Consider an Alternative to BigCommerce

BigCommerce is a capable platform. Still, specific gaps consistently push B2B and enterprise teams to look elsewhere.

B2B Is a Bolt-On, Not Native

BigCommerce grew up in D2C, and its B2B Edition is an add-on available only on the Enterprise plan. Teams running custom quotes, contract pricing, punchout catalogs, and multi-step approvals often find the DTC roots show quickly. Elastic Path handles account hierarchies, negotiated pricing, and context-aware catalogs natively, without an add-on layer.

Catalog, Variant & Data-Model Limits

The roughly 600-variant product limit and limited variant reporting make complex catalogs and multi-segment pricing hard to manage. Elastic Path's PXM decouples pricing, products, and catalogs, with unlimited catalogs and price books and no data duplication.

App Dependency & Scale

Advanced B2B functions often rely on third-party marketplace apps, adding both cost and fragility. Elastic Path delivers core B2B natively, backed by a resilient composable architecture and AI-ready commerce data for structured, agent-accessible catalogs.

Match the Platform to Your Complexity with Elastic Path

If you're running $100 million-plus in B2B or complex composable commerce, Elastic Path is the native-B2B, composable choice built for exactly that scale.

If your business is smaller or your catalog is simpler, one of the platforms above, or BigCommerce itself, is likely the better fit. Either way, you now have an honest map of where each platform stands.

FAQs

• What is the best BigCommerce alternative for B2B?

  It depends on scale. Elastic Path fits enterprise B2B with complex pricing and catalogs, while Shopify Plus suits simpler wholesale add-ons to a DTC business.

• Is BigCommerce good for enterprise B2B?

  It depends on complexity. BigCommerce's B2B Edition covers basic wholesale needs, but its DTC-first architecture limits account hierarchies and negotiated pricing at true enterprise scale.

• Are there free BigCommerce alternatives?

  Yes, to a point. Magento Open Source and Shopware's Community Edition are free to self-host, though you'll still invest in hosting, development, and maintenance.

• What is the difference between headless and composable commerce?

  Headless separates the front end from the back end. Composable goes further, building the entire stack from independent, swappable services like catalog, cart, and search.

• Can I run B2B and DTC on the same platform?

  Yes, on most of the platforms above. Elastic Path, Shopify Plus, and Shopware all support B2B and DTC storefronts from a single backend, with buyer-specific pricing and catalogs shown based on login context.

• Which BigCommerce alternative is best for AI-ready commerce?

  Elastic Path, through Product Experience Manager, structures catalog and pricing data into standards-aligned, API-first formats that LLMs and AI agents can read programmatically, which most retrofitted headless platforms weren't built to support.

• How long does an enterprise B2B replatform typically take?

  It varies by architecture. Shopify Plus can launch in weeks, while fully composable builds on commercetools commonly take several months to a year, depending on catalog and integration complexity. Elastic Path’s AI implementation tools are shortening B2B development timelines to a few months.
