our call
Start with Synder — 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.
