our call
Start with Katana — highest vibe code, weakest moat.

NetSuite
NetSuite is an enterprise accounting, inventory, and compliance machine built on 25 years of complex tax rules and transactional integrity. While an AI prompt can easily output a polished CRUD dashboard for orders and inventory, it cannot build a compliant, multi-subsidiary, audit-ready double-entry ledger that passes an independent audit.

- Simple purchase order creation and receiving workflows.
- Basic sales order management and invoice generation.
- High-level customer and vendor master record management.
- Simple financial dashboards for cash-in vs cash-out metrics.
