Formulas Required

The template relies on dynamic formulas to maintain data accuracy and enable real-time monitoring:

• =SUMIFS(Weekly_Inventory_Log!$C:$C, Weekly_Inventory_Log!$B:$B, A2, Weekly_Inventory_Log!$D:$D, "Incoming Shipment") – To calculate incoming stock per SKU.
• =SUMIFS(Weekly_Inventory_Log!$C:$C, Weekly_Inventory_Log!$B:$B, A2, Weekly_Inventory_Log!$D:$D, "Sales Order") – For outgoing sales quantities.
• =IF(CURRENT_STOCK < REORDER_POINT, "LOW", IF(CURRENT_STOCK < 0.1*REORDER_POINT, "CRITICAL", "")) – Flagging low stock conditions.
• =SUM(Stock_Level!$C:$C) – Total warehouse inventory value (calculated with cost price).
• =AVERAGEIFS(Weekly_Inventory_Log!$C:$C, Weekly_Inventory_Log!$D:$D, "Incoming Shipment") – Average weekly incoming volume.
• =VLOOKUP(A2, Inventory_Master!$A:$B, 2, FALSE) – To retrieve product description from master table.

Conditional Formatting

To improve visual clarity and support fast decision-making:

• Low Stock Highlighting: Cells in "Stock Levels & Alerts" where "Low_Level_Flag" is TRUE are formatted in yellow with bold text.
• Critical Stock Alert: Critical level cells are highlighted in red with a warning icon.
• Negative Balances: Any negative stock values are shown in red and underlined.
• High Volume Transactions: Rows where transaction quantity exceeds 100 units are highlighted in orange.
• Date Filters: All entries before the current week’s start date are shaded gray to indicate outdated data.
