Sheet-by-Sheet Description and Structure

1. Monthly Inventory Summary (Main Dashboard)

This is the central hub of the template, providing a high-level view of inventory performance for the month.

• Data Type: Summary report with formulas pulling data from other sheets.
• Columns: Month (Date), Total Products in Stock, Opening Stock Value ($), Closing Stock Value ($), Average Inventory Value ($), Inventory Turnover Ratio, Days of Supply, Reorder Level Alerts (Yes/No).
• Data Types: Date, Currency, Numeric (with decimal points for ratios).
• Formulas Used:
  • =AVERAGE(Closing_Stock_Value) – to compute average inventory.
  • =SUM(Sales_Summary!C:C)/AVERAGE(Closing_Stock_Value) – calculates inventory turnover ratio.
  • =Closing_Stock_Value/AVG_Daily_Sales – determines days of supply.
• Conditional Formatting: Red background if Days of Supply > 60 (overstock), yellow if 30–60, green if ≤30. Reorder Level Alert column highlighted in red if "Yes".

2. Inventory Transactions Log

This sheet records every movement of inventory during the month—receipts, sales, returns, and adjustments.

• Columns: Date (Date), Transaction Type (Dropdown: Receipt / Sale / Adjustment / Return), Product ID (linked to Master List), Quantity, Unit Cost ($), Total Cost ($), Location/Store Code.
• Data Types: Date, Text (for type and location), Number for quantities and costs.
• Formulas Used:
  • =IF(Transaction_Type="Sale", -Quantity, Quantity) – to adjust net inventory count.
  • =Quantity * Unit_Cost – calculates total cost per transaction.
• Conditional Formatting: Sales transactions in blue; adjustments in orange; high-value transactions (> $1,000) highlighted in bold red.

3. Product Master List & Categories

A centralized reference database for all products, categorized by type (e.g., Raw Material, Finished Goods, Packaging).

• Columns: Product ID (Unique), Product Name, Category (Dropdown: Raw Materials, Finished Goods etc.), Unit of Measure (e.g., kg, unit), Standard Cost ($), Reorder Point Quantity, Lead Time (days), Supplier Name.
• Data Types: Text for names and categories; Numbers for cost and lead time; dropdowns for category and supplier.
• Formulas Used: None directly here—this sheet serves as a lookup table. VLOOKUP formulas in other sheets reference this.

4. Sales Forecast & Demand Planning

This monthly planning worksheet helps project demand based on historical data and seasonality.

• Columns: Month (Date), Product ID, Forecasted Units (based on past 12 months average and trends), Safety Stock Required, Recommended Order Quantity.
• Data Types: Date, Text (Product ID), Number for units.
• Formulas Used:
  • =AVERAGEIFS(Transactions!C:C, Transactions!B:B, Product_ID, Transactions!A:A, ">="&StartDate) – calculates moving average demand.
  • =Forecasted_Units * 1.2 – adds 20% safety stock buffer.
• Conditional Formatting: Highlight forecasted units above historical average in green; below average in red.

Dedicated to visualizing core inventory control metrics critical for business plan evaluation.

• Data Types: Numeric, percentage-based KPIs derived from formulas across sheets.
