Sheet Names

• Daily Stock Summary: Automated daily overview of current inventory levels.
• Low Stock Alerts: Dynamic list highlighting products below reorder thresholds.
• Dashboard Overview: Visual summary with key performance indicators (KPIs), charts, and trends.

Table Structures and Data Organization

The template is built using structured Excel tables for scalability and formula reliability. Each sheet contains a properly formatted table with headers that enable automatic filtering, sorting, and formula expansion.

1. Inventory Master List (Table: tblProducts)

This is the core data repository where all product information is stored. It ensures consistency in data collection across all departments and employees.

2. Transaction Log (Table: tblTransactions)

A chronological log of every stock movement—purchases, sales, adjustments, returns—capturing essential metadata for audit trails.

3. Daily Stock Summary (Table: tblDailySummary)

An automatically updated table that pulls data from the Transaction Log and Master List to generate daily inventory snapshots.

4. Low Stock Alerts (Table: tblLowStock)

A dynamic filtered view showing products below their defined reorder levels, enabling proactive restocking.

5. Dashboard Overview

Contains key visualizations, summary metrics, and interactive controls for real-time performance monitoring.

Columns and Data Types

• Product ID (Text/Number): Unique identifier (e.g., PROD001).
• Product Name (Text): Full product name or description.
• Category (Dropdown List): Predefined categories like Electronics, Apparel, Office Supplies.
• Supplier (Text): Name of the supplier or vendor.
• Purchase Price (Currency): Cost per unit when acquired.
• Selling Price (Currency): Retail price charged to customers.
• Current Stock Qty (Number): Real-time quantity on hand, updated via formulas.
• Reorder Level (Number): Minimum stock level before triggering a reorder.
• Unit of Measure (Text): e.g., Units, Pounds, Each, Cases.
• Last Updated (Date/Time): Timestamp of last inventory change.

Formulas Required

The template uses a combination of Excel functions to ensure real-time data integrity and automation:

• Current Stock Qty Calculation (in Master List):
  =SUMIFS(tblTransactions[Qty], tblTransactions[ProductID], [@[Product ID]], tblTransactions[Type], "IN") - SUMIFS(tblTransactions[Qty], tblTransactions[ProductID], [@[Product ID]], tblTransactions[Type], "OUT")
  This formula calculates net stock by summing all incoming items and subtracting outgoing ones.
• Reorder Status (Conditional Tag):
  =IF([@[Current Stock Qty]] <= [@Reorder Level], "Reorder Required", "In Stock")
• Daily Stock Summary (via Power Query or FILTER function):
  =FILTER(tblProducts, tblProducts[Last Updated] = TODAY()) (or using a helper date column)
• Total Inventory Value:
  =SUMPRODUCT(tblProducts[Current Stock Qty], tblProducts[Purchase Price])
• Low Stock Alert List:
  Use the FILTER function to pull only rows where Reorder Status = "Reorder Required".

Conditional Formatting Rules

To improve data readability and highlight critical information:

• Low Stock Items: Apply red fill with white text for products where Current Stock Qty ≤ Reorder Level.
• Duplicate Product IDs: Highlight in orange if a product ID appears more than once (data integrity check).
• Positive vs Negative Stock Levels: Green for positive values, red for negative (indicating over-issuance).
• Pricing Differences: Light yellow highlight when Selling Price is less than Purchase Price to flag potential profit loss.
