Table Structures & Columns (Inventory Master Sheet)

The Inventory Master table is structured to support real-time inventory tracking and scalability for startups expanding their product lines. It includes the following columns:

Unit cost from supplier; used for valuation and profit margin calculations.

Price charged to customers. Used for revenue forecasting and ROI analysis.

Linked to the Supplier Performance table; ensures consistency and traceability.

Auto-updated when a new purchase is recorded via Purchase Orders sheet.

Dynamically calculated based on current stock vs. reorder point using IF and conditional formatting.

Formulas Required

This advanced template leverages a combination of lookup, logical, statistical, and array formulas:

• Dynamic Stock Update: In the Inventory Master sheet, use =SUMIFS(Sales!Qty, Sales!SKU, InventoryMaster!A2) - SUMIFS(PurchaseOrders!QtyReceived, PurchaseOrders!SKU, InventoryMaster!A2) to calculate net stock.
• Status Logic: =IF(CurrentStock <= ReorderPoint, "Low Stock", IF(CurrentStock = 0, "Out of Stock", "In Stock"))
• Reorder Recommendation: =IF(Status="Low Stock", MAX(0, (ForecastedDemand * LeadTimeDays / 30) + SafetyStock - CurrentStock), "")
• Demand Forecasting: Uses exponential smoothing formula with FORECAST.LINEAR() based on historical sales data from Sales & Dispatch Logs.
• Pivot Tables: Used in the Dashboard to summarize inventory by category, supplier, or stock status.

Conditional Formatting

• Stock Levels: Red text for "Out of Stock", yellow for "Low Stock", and green for "In Stock".
• Dates: Highlight upcoming delivery dates (e.g., within 3 days) in orange.
• Price Variance: Flag items where cost price has increased by more than 10% from last quarter using color scales.
• KPIs on Dashboard: Use traffic light indicators for performance metrics like inventory turnover and order accuracy rate.
