our call
Start with CIN7 Core — highest vibe code, weakest moat.
CIN7 Core
If you only need central multi-location inventory control and basic kitting logic, an AI prompt can build a custom database replacement in a few weeks. Replacing CIN7 Core's full capability—including deep accounting integrations, enterprise EDI, dynamic landed-cost FIFO ledgers, and MRP workflows—takes months of complex systems engineering.

Extensiv
If you just need to connect a Shopify store to a modern 3PL via REST APIs, an AI coding agent can build a custom bridge in a weekend. But if you need an enterprise WMS with physical barcode scanning, wave picking, EDI mapping for big-box retail, and a connected network of 3PLs, Extensiv cannot be replaced by a prompt.

- Standard Shopify/WooCommerce/Amazon order pulling and status updating.
- Basic multi-warehouse inventory allocation rules (nearest warehouse, full availability).
- Single-tenant dashboard for order status tracking and inventory visibility.
- Simple low-stock alert notifications via email or Webhooks.
