our call
Start with Brightpearl — highest vibe code, weakest moat.
Brightpearl
Brightpearl is not just a UI; it is an enterprise core accounting and warehouse management platform. Building a toy inventory portal is easy, but replicating its accounting ledger, 3PL syncs, and multi-channel concurrency safety takes months of senior 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.
