Sheet Names

• Inventory Master: Central repository of all products and stock details.
• Resource Allocation: Tracks labor, machinery, storage space, and other resources allocated to inventory operations.
• Reorder Alerts & Forecasting: Automatically calculates reorder points and predicts future demand using historical data.
• Purchase Orders: Logs all purchase activities with supplier details and order status.
• Stock Movement Log: Records every transaction (in/out, transfers, returns).
• Dashboard Summary: High-level visual overview of inventory health, stock levels, and planning performance.
• Settings & Parameters: Stores configuration values like lead times, safety stock thresholds, reorder quantities.

Table Structures and Data Models

The core relational structure is built around three primary tables that are linked via foreign keys:

1. Inventory Master (Product Table): Stores product-level data including SKU, category, unit of measure, cost price, retail price, and safety stock levels.
2. Stock Levels (Inventory Tracking Table): Tracks real-time stock quantities by location and warehouse. Contains daily updates for each product.
3. Resource Allocation Table: Links inventory items to labor hours, equipment usage, and storage capacity needs based on volume or value.

Columns and Data Types

Each table includes precisely defined columns with appropriate data types:

Inventory Master Table

• SKU: Text (Primary Key)
• Description: Text (Max 100 characters)
• Category: Text (e.g., Electronics, Office Supplies)
• Unit of Measure: Dropdown (e.g., pcs, kg, liters)
• Cost Price: Number (Currency format)
• Retail Price: Number (Currency format)
• Safety Stock Level: Number (Integer)
• Max Stock Level: Number (Integer)
• Min Stock Threshold: Number (Integer, auto-calculated from safety stock)

Stock Levels Table

• SKU: Text (Foreign Key to Inventory Master)
• Warehouse Location: Text (e.g., W1-A, B2-C)
• Date: Date/Time (Auto-filled with today’s date)
• On Hand Quantity: Number (Integer, tracked daily)
• Reserved Quantity: Number (Integer, for pending orders or production needs)
• Total Available Stock: Calculated field (On Hand - Reserved)
• Status Flag: Text (e.g., "In Stock", "Low", "Out of Stock")

Resource Allocation Table

• SKU: Text (Foreign Key)
• Resource Type: Dropdown (Labor, Equipment, Storage)
• Unit Required per Item: Number (e.g., 0.5 labor hours per unit)
• Total Units Projected This Month: Number (from forecasting)
• Total Resource Needed: Calculated field (Units × Unit Requirement)
• Current Resource Allocation: Number (manual or auto-populated)
• Resource Deficit/Surplus: Calculated field (Total Needed - Current)

Formulas Required

The template uses dynamic formulas to ensure real-time updates:

• Total Available Stock = On Hand Quantity – Reserved Quantity
• Stock Status = IF(Total Available Stock < Safety Stock Level, "Low", IF(Total Available Stock <= 0, "Out of Stock", "In Stock"))
• Reorder Point = Min Stock Threshold + (Daily Average Usage × Lead Time) (in Reorder Alerts sheet)
• Monthly Forecast = AVERAGE(Previous 6 Months’ Sales) × (1 + Growth Rate %)
• Total Resource Needed = Projected Units × Unit Requirement
• Resource Deficit/Surplus = Total Resource Needed – Current Allocation
• Automated alerts trigger when stock falls below safety thresholds or resource deficits exceed 10%.

Conditional Formatting Rules

• Stock Status Cells: Green for "In Stock", Yellow for "Low", Red for "Out of Stock".
• Reorder Alerts: Red background if stock below safety level; Orange if approaching threshold.
• Resource Deficit: Negative values in red, positive values in green to indicate surplus.
• Duplicate SKUs: Highlight rows where SKU matches across different locations (potential error).
• Date-based filters: Conditional formatting shows "Past Due" entries where order date exceeds 30 days.

5. Navigate to the Dashboard Summary for a visual summary of inventory turnover, stockout risks, and resource needs.
6. To adjust parameters, go to the Settings & Parameters sheet and modify safety stocks, lead times, or reorder quantities.
7. Save the file as an .xlsx format with version control (e.g., “V1.2 – 04-2024”).
