This sheet defines all unique inventory items in the system. The structure is minimal yet comprehensive, ensuring clarity and ease of updates.

• Last Updated: Date/time auto-populated when edited.
• Status: Text field (e.g., "In Stock", "Low", "Out of Stock") – dynamically updated via formula.

2. Resource Planning Sheet

This sheet supports forecasting and planning for future stock needs based on historical usage patterns and demand estimates.

• Plan Period (e.g., Month/Quarter): Text input (e.g., "Jan 2025")
• Item ID: Link to Inventory Master via VLOOKUP
• Predicted Demand: Integer; estimated required quantity for the period.
• Expected Usage Rate (per day/week): Decimal (e.g., 2.5 units/day)

4. Dashboards Sheet

A visual summary of key metrics using tables and charts for quick decision-making.

• Average Usage Rate (by category): Aggregated average from the Resource Planning sheet.
• Total Transactions This Month: COUNTA of transactions in the last 30 days.

Formulas and Calculations Required

The template uses only essential Excel formulas to ensure clarity and performance:

• =IF(Current Stock < Reorder Level, "Low", "In Stock"): Updates status dynamically.
• =MAX(0, Predicted Demand - Current Stock): Calculates required order quantity.
• =SUMIFS(Transactions!$B:$B, Transactions!$A:$A, >=TODAY()-30): Counts transactions in the last 30 days.
• =VLOOKUP(Item ID, Inventory Master!$A:$D, 4, FALSE): Fetches unit of measure or other details.
• =SUM(Transactions!$C:$C) (filtered by date) to calculate net movement.

Conditional Formatting Rules

To enhance readability and alert users to critical inventory levels, conditional formatting is applied:

• Status column in Inventory Master: Green if "In Stock", Yellow if "Low", Red if "Out of Stock".
• Current Stock values below Reorder Level: Highlighted in red with a warning message.
• Forecasted demand exceeding current stock: Flagged in orange for review.
• Transactions sheet: Date filter by last 7 days: Background color changed to light blue to indicate recent activity.

Recommended Charts and Dashboards

To support data-driven decision-making in resource planning, the following charts are recommended:

• Heat Map of Stock Status by Category: Highlights which categories have low or no stock.

The Dashboards sheet integrates these visualizations using Excel’s built-in chart tools, enabling quick interpretation without needing external software.
