our call
Start with Inventory Planner — highest vibe code, weakest moat.
Inventory Planner
While simple reorder point math can be scripted in a afternoon, replacing Inventory Planner's full UX is a massive engineering effort. The app relies on complex statistical forecasting, stockout masking, multi-location transfers, and an inline-editable matrix grid optimized for high-volume SKU management.
you can rebuild
- Basic moving-average and order velocity calculations per SKU
- Simple reorder point triggers based on static lead times and safety stock
- Automated PDF or CSV Purchase Order draft creation
- Low stock alerts delivered via email or Slack
- Basic historical sales data import via Shopify Webhooks/APIs
what you lose
- Stockout days auto-adjustment (removing zero-sales days caused by stockouts from velocity math)
- Advanced statistical forecasting models (Holt-Winters, linear regression with seasonal indicators)
- Bill of Materials (BOM) assembly stock explosion for raw component planning
- High-density, spreadsheet-like inline editing UX optimized for bulk adjustments
- Native multi-warehouse transfer recommendations and multi-location balancing
real moats
- Deep data grid UI engineering with inline cell overrides and instant recalculated projections
- Battle-tested forecasting algorithms refined across edge cases like stockouts, promotions, and supply chain delays
- Pre-built integrations with major ERPs, WMSs, purchase order systems, and sales channels

StockIQ
StockIQ is far beyond a simple reorder alert dashboard; it handles multi-echelon statistical forecasting, vendor lead-time variance, container load optimization, and deep enterprise ERP sync. While basic moving-average reorder scripts are quick to build with AI, replicating StockIQ's full mathematical rigor and operational edge cases for high-volume distributors requires serious domain engineering.
you can rebuild
- Basic reorder point notifications based on static stock thresholds
- Simple moving average historical demand forecasting
- Purchase order PDF generation and supplier email triggers
- Vendor record keeping and manual lead time logging
- Basic SKU-level velocity and inventory health dashboards
what you lose
- Advanced statistical forecasting engines (Holt-Winters, Croston's method)
- Multi-echelon inventory allocation across regional distribution hubs
- 3D container load optimization and cubic fill calculations
- Native bi-directional lock-safe ERP synchronization
- Supplier performance scoring and automated lead-time variance tracking
real moats
- Deep bidirectional sync capabilities with legacy and enterprise ERPs
- Proprietary supply chain algorithms for multi-echelon replenishment planning
- Extremely high operational switching costs once implemented across distribution centers
