Sheet Names

Table Structures

The core of this template is built on two primary tables:

1. Inventory Master Table (Sheet: Inventory Master)

• This table stores all product information with a unique SKU as the primary key.
• Each row represents a single inventory item, including details such as name, category, supplier, unit of measure (UoM), and current cost per unit.

2. Weekly Inventory Log Table (Sheet: Weekly Inventory Summary)

• This is a time-structured table that captures inventory levels at the end of each week.
• It links to the Master table using SKU and includes weekly date ranges, opening balance, purchases, sales, and closing stock.

Columns and Data Types

All data is structured with clear data types to ensure accuracy:

Formulas Required

• Closing Stock Calculation: = Opening Stock + Purchases - Sales
• Total Inventory Cost: = Closing Stock * Cost per Unit (using VLOOKUP or INDEX/MATCH to find cost)
• Weekly Variance: = (Closing Stock - Average Weekly Target) to identify deviations.
• Daily Average Sales Rate: = SUM(Sales) / Number of Days in Week (used in forecasting).
• Cost per Category: Uses SUMIFS and categorized grouping across the master table.

Conditional Formatting

• Low Stock Alert: Cells with Closing Stock < 5 are highlighted in red.
• High Cost Items: Any item with Cost per Unit > $100 is flagged in yellow.
• Variance Highlighting: Negative variances (overstock or understock) are shown in orange.
• Duplicate SKU Detection: Red flag if a SKU appears more than once without explanation.
