our call
Start with Solidus — highest vibe code, weakest moat.
Solidus
There is no licence to escape. Rebuilding makes sense only if you want to leave Ruby; otherwise you are trading a maintained core for a bespoke one.
you can rebuild
- Catalog, variants and option types
- Cart, checkout and order state machine
- Promotions with basic rules and actions
- Admin interface for orders and products
what you lose
- A maintained upgrade path with a security-conscious core team
- Rails extensions for payments, taxes and reporting
- Free bug fixes from other people's production incidents
real moats
- An active maintainer community absorbing edge cases you have not hit yet

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.
