Magento B2B vs Shopify Plus B2B vs BigCommerce B2B — which?

Honest comparison:

• Magento / Adobe Commerce B2B — the most flexible. Companies, multi-tier pricing, quote workflow, ERP integration, custom approval matrices, headless GraphQL. Best for $1M+ GMV B2B with custom workflows or ERP-heavy stacks.
• Shopify Plus B2B — fastest to launch, B2B added in 2023 (companies, catalogue access, payment terms). Limited customisation — you live within Shopify’s data model. Best for < $5M GMV B2B with simple workflows and no heavy ERP.
• BigCommerce B2B Edition (powered by B2B Ninja / BundleB2B) — mid-ground. Quote workflow, customer groups, price lists. Less mature than Magento for complex flows.

If your B2B has 5+ approval roles, custom pricing logic, an ERP, or 5,000+ SKUs, Magento wins on TCO and capability. If you’re a small distributor wanting to launch in 30 days, Shopify Plus B2B is faster. We’re happy to recommend the route that actually fits your business — even if it isn’t Magento.
