our call
Start with BigCommerce — highest vibe code, weakest moat.
BigCommerce
You can build a clean React shopping cart and a basic Node/Postgres backend with AI in a weekend. You cannot easily replace BigCommerce's deeply complex B2B pricing matrices, multi-inventory state machine, complex tax engines, or PCI-compliant checkout infrastructure without a massive ongoing engineering commitment.
you can rebuild
- Basic store frontend themes and responsive catalog display.
- Single-page checkout interface.
- Standard CSV product import/export tools.
- Basic customer group segmentation and manual coupon code engine.
- Simple multi-currency display and manual rate overrides.
what you lose
- Out-of-the-box PCI-DSS Level 1 compliant hosted checkout infrastructure.
- Native B2B enterprise suite (company account hierarchies, invoice payment terms, custom price lists).
- Deep pre-built integrations with top ERPs, POS systems, and tax services (Avalara, Vertex).
- 24/7 dedicated enterprise infrastructure monitoring and SLA guarantees.
- Access to Feedonomics surface for automated multi-channel marketplace feed management.
real moats
- Decade-long ecosystem of native ERP, CRM, and fulfillment integrations (Acumatica, NetSuite, SAP).
- Built-in enterprise B2B functionality (Company accounts, net terms, custom price lists, buyer permissions).
- Turnkey compliance stack (PCI-DSS Level 1, SOC 2 Type II, ISO 27001).
open source escape hatches
- Medusa MIT
- Saleor BSD-3
- WooCommerce GPL-3.0
Shopify Plus
An AI can rebuild the admin screens of Shopify Plus in weeks. It cannot rebuild Shop Pay, the Black Friday capacity guarantee, the checkout extensibility sandbox, or the contractual SLA that makes a CFO sign off on $2,300+/mo.
you can rebuild
- Admin dashboard, catalog and variant management
- Discount and promotion rule engine
- Order and fulfilment workflow screens
- B2B company accounts and custom price lists for a handful of buyers
- Wholesale/expansion storefront as a separate lightweight site
what you lose
- Shop Pay's saved-wallet 1-click checkout and its measurable conversion lift.
- Contractual 99.99% uptime SLA and Black Friday capacity planning.
- Checkout extensibility and Shopify Functions running server-side at the edge.
- Out-of-scope PCI-DSS: Shopify holds the card data, you do not.
- Multi-store organisation management with shared catalog and centralised roles.
real moats
- Shop Pay buyer network with hundreds of millions of saved wallets.
- Peak-event infrastructure proven at millions of checkouts per minute.
- Payments, Capital, Balance and Installments bundled into the same contract.
- App and agency ecosystem trained specifically on the Plus extension model.
