our call

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

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

real moats

  • Extension ecosystem and long-running community
  • Accumulated commerce edge cases in tax, promotions and returns

TradeCentric

Building a custom PunchOut proxy for a known, single enterprise buyer (e.g., SAP Ariba to Shopify) takes a few weeks of TypeScript work. Replacing TradeCentric as a general-purpose hub for 50+ enterprise buyers using custom cXML/EDI schemas requires a dedicated integration ops team.

you can rebuild

  • Basic cXML PunchOutSetupRequest parsing and response generation.
  • Session token handshake and cart transfer (PunchOutOrderMessage generation).
  • Standard cXML Purchase Order (OrderRequest) ingestion to Shopify Draft Orders.
  • Outbound cXML InvoiceDetailRequest dispatch on fulfillment.
  • Basic transaction log dashboard for session status and PO tracking.

what you lose

  • Turnkey connectivity to 150+ eProcurement systems (SAP Ariba, Coupa, Jaggaer, Oracle, Workday).
  • Dedicated integration engineers who interface directly with enterprise buyer IT teams during testing.
  • Pre-built handling of thousands of vendor-specific cXML and OCI schema deviations.
  • Managed monitoring and alerts for partner-side endpoint outages and SSL failures.
  • ISO 27001 certified data handling for enterprise procurement compliance.

real moats

  • Human-managed onboarding and white-glove setup teams for enterprise procurement buyer testing.
  • Deep library of non-standard cXML/EDI parser edge cases built over a decade of buyer integrations.
  • 3-year enterprise lock-in contracts with $100M+ revenue suppliers.
