Best E-Commerce Platforms for B2B: Shopify Plus vs BigCommerce vs Magento vs Salesforce Commerce

B2B e-commerce is undergoing a digital transformation. With the global B2B e-commerce market expected to reach $20.9 trillion by 2027 (Forrester, 2026), choosing the right platform is critical.

I evaluated 5 leading B2B e-commerce platforms to help you decide.

At a Glance: B2B E-Commerce Platforms Compared

Shopify Plus — Best for Mid-Market B2B

Shopify Plus has rapidly evolved from a B2C platform to a legitimate B2B player with features like customer-specific pricing, wholesale channels, and customizable checkout.

What I like: The speed of deployment is unmatched — most stores go live in weeks, not months. G2 users rate it 4.4/5 with 91% satisfaction for ease of use. The B2B features (quantity rules, price lists, company profiles) have matured significantly.

What I don't like: Enterprise-level customization has limits compared to Magento or Salesforce Commerce. High-revenue merchants face transaction fees unless using Shopify Payments. Complex B2B pricing and inventory rules can require expensive third-party apps.

Pricing: $2,000/month (Shopify Plus), with additional platform fees based on revenue.

The Bottom Line

Choose Shopify Plus for speed of deployment and ease of use. Pick BigCommerce for native features without app dependencies. Magento offers the deepest customization for large enterprises. Salesforce Commerce Cloud is best for Salesforce CRM users. WooCommerce is ideal for WordPress-based stores on a budget.
