Start with CIN7 Core — 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.
