B2B distributor accounts on the same Magento as B2C — how does it work?

This is Magento’s home-court advantage. One backend, two storefronts (or one storefront with logged-in B2B switching), fully separated pricing and catalogs.

• Customer groups: create "Wholesale Tier 1", "Wholesale Tier 2", "Distributor", "Reseller" customer groups. Each group gets its own price tier per SKU.
• Shared catalogs (Adobe Commerce B2B): assign different SKU subsets to different customer groups. E.g. distributors see professional-only SKUs that B2C never sees.
• Companies + buyer roles: B2B customers belong to companies with multi-buyer / multi-approver / company-admin roles. Native in Adobe Commerce; available via Aheadworks / Mageplaza B2B in Open Source.
• Quote workflow: distributor requests a quote, sales rep reviews, multi-step approval, converts to order. Native Adobe Commerce. Aheadworks "B2B" for Open Source.
• Net-30 / payment terms: per-customer terms (Net-15, Net-30, Net-60). Adobe Commerce native; Open Source via Mageplaza Payment Terms ($199 one-time).
• Tax exemption: per-company resale certificates, tax-exempt customer groups, integration with Avalara / TaxJar for cross-state US distributor tax.

The B2C storefront stays clean — consumers never see distributor pricing or trade-only SKUs. Logged-in B2B users automatically see their tier prices, requisition lists, and quote tools without a separate URL.
