our call
Start with Katana — highest vibe code, weakest moat.
CIN7 Omni
You can easily build a custom inventory sync and PO tool using modern stack frameworks in a few weeks. However, fully replacing Cin7's multi-channel state locking, landed-cost accounting, nested BOM assemblies, and deep 3PL/Xero integration matrix takes significant engineering time.
