our call
Start with Katana — highest vibe code, weakest moat.
Katana
You can build a simple assembly management UI and stock ledger with AI in a couple of weeks. Replicating full multi-level BOM explosion, FIFO lot traceability, landed cost rollups, and concurrent two-way integrations without database corruption requires months of production testing.
you can rebuild
- Basic single-level Bill of Materials (BOM) management.
- Purchase order auto-generation based on minimum inventory thresholds.
- Shop floor completion tracking UI and task scheduling.
- Sales order routing and multi-location inventory counts.
- CSV import/export for stock balances and item master lists.
what you lose
- Out-of-the-box Shopify, WooCommerce, QuickBooks, and Xero sync logic.
- Battle-tested lot traceability data records required during audit recalls.
- Pre-packaged Shop Floor mobile web app for assembly line workers.
- Automated multi-currency rate updates and landed cost accounting algorithms.
- 24/7 dedicated customer support and onboarding solutions engineering.

Logiwa WMS
Logiwa is not just a relational database of product locations; it is an industrial execution system. It coordinates barcode scanners, local print servers, automated rate-shopping, and multi-tenant warehouse billing. Attempting to build a custom WMS using LLMs will result in physical warehouse bottlenecks, inventory allocation race conditions, and missed shipping SLAs.
