Supply Chain BOM Explosion, Safety Stock & Reorder Point (ROP) Calculator with AI
Tired of losing sales to stockouts during peak season or tying up cash in dead inventory? Feed historical daily sales variance, supplier lead times and multi-level BOMs into AI to calculate statistically sound Safety Stock, Reorder Points (ROP) and purchase schedules.
CORE TOOLS
Excel / CSV, DeepSeek R1 / Claude
BEST FOR
E-commerce sellers, PMC planners, hardware founders, retail managers
REQUIREMENTS
SKU sales history and supplier lead times; Excel + any LLM
✦ WHY THIS WORKFLOW
Small brands either bleed cash from stockouts right after a viral spike or suffocate in dead stock. Replacing gut-feel ordering with statistical ROP formulas balances cashflow and availability.
Act as a Certified Supply Chain Planning Director (APICS CPIM).
Here is my SKU demand, inventory and supplier data:
- **Historical Sales (Average daily sales & variance)**: [Paste data]
- **Supplier Lead Time (Days, variability & MOQ)**: [Paste data]
- **BOM Component Ratios (if applicable)**: [Optional]
- **Current On-Hand + On-Order Inventory**: [Paste data]
Deliver:
1) [ABC Classification & Target Service Levels ($Z$-scores)];
2) [Safety Stock & Reorder Point (ROP) Calculation Table]: Show step-by-step math factoring in both demand and lead-time variability;
3) [Immediate Stockout Risk & Purchase Order Action List]: Flag SKUs where (On-Hand + On-Order) < ROP;
4) [Copy-Paste Excel Formulas]: Using `NORM.S.INV`, `STDEV.S` and conditional formatting triggers.
