Sheet Names & Purpose

Table Structures & Column Definitions

1. Inventory Master Table (Sheet: Inventory Master)

2. Daily Transactions Table (Sheet: Daily Transactions)

3. Reorder Alerts Table (Sheet: Reorder Alerts)

This table automatically filters Inventory Master where Current Stock Level ≤ Reorder Point.

Formulas & Calculations

• Current Stock Level (Auto-updated): Uses SUMIFS to calculate net stock from Daily Transactions: =SUMIFS('Daily Transactions'!$D:$D, 'Daily Transactions'!$B:$B, A2)
• Stock Status Indicator: Conditional text label using IF and AND functions: =IF([@Current Stock Level] <= [@Reorder Point], "Critical", IF([@Current Stock Level] <= [@Reorder Point]*1.5, "Low", "Normal"))
• Days of Supply: Calculates how many days until stock runs out: =IF([@Average Daily Usage]>0, [@Current Stock Level]/[@Average Daily Usage], 0)
• Average Daily Usage (from Sales History): Uses AVERAGE and DATE functions to calculate average sales over 30/60/90 days: =AVERAGEIFS('Sales History'!$D:$D, 'Sales History'!$A:$A, ">= "&TODAY()-90)
• Reorder Quantity: Suggested order size using EOQ formula (Economic Order Quantity): =SQRT((2*[@Annual Demand]*[@Ordering Cost])/[@Holding Cost])

Conditional Formatting Rules

• Critical Stock Levels: Red fill with white text when Current Stock Level ≤ Reorder Point
• Low Stock Levels: Orange fill with dark text when Current Stock Level ≤ 1.5 × Reorder Point
• High Turnover Items: Green background for products with average daily usage above the median
• Dates in Past: Light red highlight for transaction dates older than 30 days without status update
