Inventory Forecasting & Reorder Optimizer — Automated ROP & Safety Stock Sheet

Most e-commerce spreadsheets and standard retail inventory trackers are glorified counting logs. They record how many units sit on warehouse shelves, but completely fail to model daily sales velocity, supplier lead-time variance, or required safety stock buffers.

When product brands rely on static spreadsheets or guesswork to reorder inventory, they inevitably suffer from two fatal extremes: stockouts that destroy organic marketplace rank and forfeit revenue to competitors, or dead overstock that traps tens of thousands of dollars in stagnant working capital.

The Inventory Forecasting & Reorder Optimizer transforms standard stock tracking into an executive-grade supply chain command center. Built natively and exclusively for Google Sheets, it bridges the gap between raw warehouse stock counts and automated, mathematically rigorous purchase order execution:

• Automated Reorder Point (ROP) Algebra: Stop guessing when to reorder stock. Input your current warehouse stock, daily sales velocity, and item cost. The background engine dynamically maps supplier transit lead times and safety stock buffers to compute your exact Reorder Point (ROP)—the precise unit threshold where a new purchase order must be placed to prevent a stockout.
  

• Days of Cover (DIL) & Overstock Diagnostics: The system continuously audits product runway by calculating your exact Days of Cover (DIL). It automatically classifies SKU health with high-contrast visual tags: 🟢 HEALTHY COVER for stable inventory, 🟡 APPROACHING REORDER as runway narrows, 🚨 REORDER NOW (Below ROP) when stock breaches safety thresholds, and 🟣 OVERSTOCK (Dead Capital) when inventory exceeds macro holding ceilings.
  

• Supplier Taxonomy & Lead-Time Mapping: Easily establish up to 17 supplier origin categories (e.g., DOMESTIC-LOCAL, ASIA-SEA-FREIGHT, EUROPE-AIR-FREIGHT) alongside their standard transit lead times in days. Assign suppliers via simple validation dropdowns, and the engine automatically factors transit times into your reorder algebra.
  

• Macro Supply Chain Setup Canvas: Establish global operational baselines on a dedicated setup dashboard. Define your target safety stock buffer days, overstock threshold ceilings, annual inventory holding costs (%), and financial stockout risk multipliers to drive universal accuracy across your entire catalog.
  

• The C-Suite Command Center Dashboard: Get an instant, bird's-eye view of your brand's physical asset health. Monitor Active Tracked SKUs, Total Inventory Book Value ($), and isolate trapped cash immediately with automated rollups for Cash Tied in Overstock ($) alongside exact risk counts for Immediate Reorder Alarms and Overstock Dead Capital SKUs.
  

• Global SKU Stock Cover Hierarchy: A software-grade executive summary table that ranks your active catalog side-by-side. Identify your true runway risks at a glance and prioritize purchase order placements with institutional authority.
  

• Digitally Shrink-Wrapped Architecture: Engineered strictly as a cloud-native Google Sheet. Only the soft yellow (#FEF08A) input cells are unprotected. Your master tracking equations, velocity algorithms, and presentation grids are entirely locked down to guarantee zero operational calculation drift or #REF!errors.
