This comprehensive Excel template is designed for operations teams managing product inventory across multiple warehouses, distribution centers, or retail locations. As part of the "Operations Dashboard" suite, this "Product Inventory (Extended)" version provides a robust analytical foundation for real-time tracking, forecasting, and strategic decision-making. The template integrates advanced data structures with dynamic visualizations to support scalable inventory operations in manufacturing, e-commerce, logistics, and supply chain environments.

Sheet Structure

• 1. Inventory Master List: Core table containing all product SKUs, categories, suppliers, current stock levels.
• 2. Stock Movement Logs: Detailed record of inbound/outbound transactions including dates, quantities, and reasons.
• 3. Reorder Alerts & Forecasting: Automated calculations for reorder points based on demand trends and lead times.
• 4. Warehouse Performance: KPIs per warehouse including turnover rate, stock accuracy, fill rate, and shrinkage.
• 5. Summary Dashboard (Interactive): Centralized visual overview with charts, filters, and real-time metrics.

Table Structures & Columns

The template features five interconnected sheets with precisely defined table structures to support enterprise-grade operations.

Sheet 1: Inventory Master List

Sheet 2: Stock Movement Logs

Formulas & Calculations

• Economic Order Quantity (EOQ) Formula: SQRT((2 × Annual Demand × Ordering Cost) / Holding Cost per Unit)
• Reorder Point Calculation: Average Daily Usage × Lead Time + Safety Stock
• Stock Accuracy Rate (Warehouse Performance): (Counted Items Matched / Total Counted) × 100%
• Demand Forecast (30-day Moving Average): AVERAGEIFS(Quantity, Date, ">=Today()-30")
• Auto-Refresh Last Updated: =NOW() with conditional formatting to only update on edits.

Conditional Formatting Rules

The template applies visual cues for instant operational awareness:

• Low Stock Alert: Red fill if Current Stock Level ≤ Reorder Point.
• Overstock Warning: Yellow highlight if stock exceeds 150% of EOQ.
• New Items (Last 7 Days): Green border for products updated in the last week.
• Damaged/Returned Items: Orange font and background for records with "Damage" or "Return" in Reason Code.
• Negative Stock Levels: Red text and exclamation icon — critical alert state.
