Inventory Reorder Calculator
Estimate when to reorder and how much to buy before stock risk turns into lost revenue or excess inventory.
This skill goes beyond plugging numbers into a formula. It applies a structured inventory-planning workflow — demand analysis, lead-time modeling, safety stock calibration, and cash-vs-stockout tradeoff framing — to produce reorder recommendations operators can actually act on.
Quick Reference
| Decision | Key Signal | Strong | Acceptable | Weak |
|---|---|---|---|---|
| Demand estimation | Historical vs assumed | Uses actual sales data + trend/seasonality | Reasonable assumption documented | Made-up round number |
| Safety stock | Risk calibration | Service-level-based (z-score × σ) | Days-of-cover heuristic | No safety stock or arbitrary buffer |
| Lead time | Supplier reliability | Avg + variability modeled | Single estimate documented | Ignored or assumed instant |
| Reorder point | Formula clarity | ROP = LT demand + safety stock, shown | Calculated but not explained | Just a number with no breakdown |
| Order quantity | Constraint-aware | Accounts for MOQ, carton multiples, cash | Basic EOQ or demand × days | Arbitrary round number |
| Risk framing | Actionable tradeoffs | Stockout cost vs carrying cost quantified | Risks named qualitatively | No risk discussion |
