our call
Start with Swell — highest vibe code, weakest moat.
Swell
A headless commerce API is a well-understood build. What Swell sells is not having to run it: uptime, dashboard, subscription billing and payment plumbing maintained by someone else.
you can rebuild
- Products, variants and pricing rules via API
- Cart, checkout session and order APIs
- Customer accounts and saved payment methods
- Webhook events for downstream systems
- A basic merchant dashboard
what you lose
- A maintained subscription billing engine with retries and dunning
- Hosted uptime and scaling during traffic spikes
- Prebuilt payment, tax and shipping integrations
- A dashboard non-developers can operate
real moats
- Maintained integrations across payments, tax and shipping
- Subscription billing correctness accumulated across merchants
- Operational reliability you would otherwise staff for
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.
open source escape hatches
- OroCommerce OSL-3.0
- Vendure B2B MIT
- Odoo Sales & Purchase LGPL-3.0
