Can Open Source + extensions match AC’s B2B Companies module?
~85% parity, yes. The OS B2B stack I recommend in 2026:
- mage2kishan B2B Suite (or Aitoc / Bizzbee / Magenest), multi-buyer accounts, role permissions, company-specific catalogs, ~$1.5-3k one-time.
- Mageworx Negotiable Quotes, RFQ workflow with multi-round negotiation, ~$400.
- Aheadworks / Mageplaza Requisition Lists, recurring SKU ordering, ~$300.
- Net-30 + Purchase Order: Mageplaza Net Terms or custom (~$1k one-time).
Total ~$3-5k one-time vs AC’s $30-80k/yr recurring. What you don’t get from the OS stack: AC’s admin UX polish on the company-account flows, and tight Adobe-Analytics-driven segment-based pricing. For most B2B stores under $15M GMV, the OS stack is the right answer.
