our call

Start with Spree Commerce — highest vibe code, weakest moat.

Sana Commerce

AI can build the front-end B2B portal, quote flow, and cart in a few afternoons. However, Sana's entire enterprise business is built around deep, proprietary ERP web service integration with SAP and Microsoft Dynamics that runs natively inside ERP codebases.

you can rebuild

  • B2B Customer Portal UI (Order history, invoice downloads, account balances).
  • Quote-to-order conversion workflows and sales agent order-on-behalf-of impersonation.
  • Customer-specific catalog presentation and segment-based navigation menus.
  • RMA (Returns & Refunds) request forms and status tracking.
  • B2B quick-order grids, CSV order upload, and re-order lists.

what you lose

  • Native in-ERP add-ons (AL extensions for Dynamics 365, ABAP objects for SAP) that expose ERP pricing and business logic safely via web services.
  • Out-of-the-box integration with legacy ERP systems (SAP ECC, NAV, AX, Business One).
  • Battle-tested ERP failover handling and transaction lock protection.
  • Certified enterprise security and compliance standards required for ERP data exposure.
  • Automated multi-currency, multi-entity tax and credit check logic embedded in enterprise financial modules.

real moats

  • Pre-packaged enterprise ERP integrations (proprietary ABAP modules for SAP and C/AL or AL extensions for Dynamics) tested against 20+ years of ERP version quirks.
  • Real-time pricing and stock engine capable of executing complex ERP logic (trade agreements, matrix discounts, dynamic tax calculation) without crashing enterprise ERPs under heavy load.
  • Deep industry reputation and certified partner network with SAP and Microsoft Dynamics integrators.

Spree Commerce

Spree is free code you already own. Rebuilding it in a modern stack is realistic; you inherit the maintenance and lose the Rails extension ecosystem.

you can rebuild

  • Catalog, taxonomy and variant modelling
  • Cart and multi-step checkout
  • Order, shipment and return records
  • Admin CRUD screens
  • Multi-store and multi-currency basics

what you lose

  • The Rails extension ecosystem (payments, subscriptions, analytics)
  • Years of accumulated promotion and tax edge cases
  • Upstream security releases
  • Developers who already know the API surface
