Table Structures and Columns

The template uses structured tables (Excel Tables) with defined column headers for clarity and formula compatibility. All data is organized in a tabular format optimized for filtering and sorting.

1. Inventory Log (Weekly)

This table serves as the primary data collection point. It includes:

2. Summary Dashboard

This sheet aggregates weekly data into visually digestible summaries and trend analysis. It pulls information from the Inventory Log using structured references.

3. Data Validation & References

This hidden sheet contains named ranges for dropdowns and master data:

• Product Categories: Electronics, Clothing, Tools, Consumables
• Suppliers: TechSupply Inc., Global Distributors LLC, Local Depot
• Units of Measure: Units, Pairs, Cases (24 units), Kilograms
• Status Codes: In Stock, Low Stock (<10 units), Out of Stock

4. Weekly Review Tracker

A simple log to record actions taken during the week:

• Date of Review
• Product ID/Name
• Action Taken (e.g., Reorder, Audit Stock, Discontinue)
• Notes

Formulas Required

The template leverages dynamic Excel formulas for automation and error prevention:

• Auto-generated Product ID: =CONCAT("PROD-", TEXT(ROW()-1,"000"))
• Ending Stock Calculation: =[@[Beginning Stock (Week Start)]] + [@Received] - [@Sold/Issued]
• Week Ending Date: =TEXT(DATE(YEAR([@Date]), MONTH([@Date]), DAY([@Date]) + 7 - WEEKDAY([@Date], 2)),"mm/dd/yyyy")
• Status Auto-Labeling: =IF(AND(@[Ending Stock (Week End)] <= 10, @[Ending Stock (Week End)] > 0), "Low Stock", IF([@[Ending Stock (Week End)]] = 0, "Out of Stock", "In Stock"))
• Summary Dashboard Formulas: Use SUMIFS(), COUNTIFS(), and AVERAGEIFS() to compute weekly totals by category, average stock levels, number of low-stock items.

Conditional Formatting

To enhance data visibility and immediate issue detection:

• Low Stock Alert (Yellow Fill): Apply conditional formatting to the "Ending Stock" column if value ≤ 10.
• Out of Stock (Red Fill): Highlight rows where "Ending Stock" is zero.
• Rising Trends: Use data bars in the "Received During Week" and "Sold/Issued During Week" columns to visualize usage patterns.
• Last Updated Timestamp: Apply red font if last update was more than 24 hours ago (using a formula-based rule).
