Data Tables and Columns by Sheet

1. Annual Inventory Plan (Main Planning Hub)

• Column A: Item ID (Text/Number): Unique identifier for each product or inventory item.
• Column B: Product Name (Text): Full name of the item.
• Column C: Category (Dropdown List): e.g., Raw Materials, Finished Goods, Packaging Supplies. Predefined list with data validation.
• Column D: Annual Forecasted Demand (Number - Integer): Total units expected to be consumed or sold annually based on sales projections.
• Column E: Safety Stock Level (Number - Integer): Minimum inventory level to prevent stockouts.
• Column F: Reorder Point (Formula-Based): Calculated as (Monthly Demand × Lead Time in Months) + Safety Stock. Uses a formula referencing D and E.
• Column G: Order Quantity (Number - Integer): Standard batch size for reordering, based on EOQ or supplier constraints.
• Column H: Average Unit Cost (Currency): The typical cost per unit from suppliers.
• Column I: Annual Holding Cost Rate (%): Percentage of cost to store one unit for a year (e.g., 15%).
• Column J: Total Annual Inventory Cost (Formula): = (Annual Demand × Unit Cost) + ((Order Quantity / 2) × Unit Cost × Holding Rate). Automatically calculated.

2. Current Inventory Ledger

• Column A: Date Updated (Date)
• Column B: Item ID (Text/Number)
• Column C: Product Name
• Column D: Quantity On Hand (Integer)
• Column E: Location in Warehouse (Text): e.g., Aisle-3, Bin-B7.
• Column F: Last Received Date (Date)
• Column G: Expiry Date or Shelf Life (Date – Optional)

3. Purchase Orders & Replenishment Tracking

• A: PO Number (Text)
• B: Supplier Name (Text)
• C: Item ID & Product Name
• D: Ordered Quantity (Integer)
• E: Expected Arrival Date (Date)
• F: Status (Dropdown: Pending, In Transit, Delivered, Cancelled)
• G: Received Quantity (Integer – Manual Input After Delivery)
• H: Variance (Formula): = D - G

4. Monthly Performance Dashboard (Interactive Charts & KPIs)

• Real-time summary of inventory turnover ratio, stockout frequency, carrying cost vs budget, and safety stock compliance.
• Data sourced dynamically from the other sheets using INDEX/MATCH or XLOOKUP formulas.

Required Formulas

• Reorder Point (Cell F2): =ROUND((D2/12)*E3 + E$5, 0)
• Total Annual Inventory Cost (J2): =D2*H2 + ((G2/2) * H2 * I$5)
• Inventory Turnover Ratio (Dashboard): =SUM(Annual Demand Column) / AVERAGE(On-Hand Inventory Across Months)
• Stockout Flag: =IF(D3=0, "⚠️ Stockout", "✓ In Stock")

Conditional Formatting Rules

• Low Stock Alert (Current Ledger): Apply red fill to rows where On Hand Quantity is less than Reorder Point (conditional formula: =D3 < $F$5).
• Critical Expiry Warning: Yellow highlight for items with expiry date within next 30 days.
• Overstock Alert: Orange fill if Quantity On Hand exceeds forecasted demand by more than 25%.
• Purchase Order Status Color Coding: Green (Delivered), Yellow (In Transit), Red (Pending/Canceled).

User Instructions

Step-by-Step Usage Guide:

1. Startup Planning Phase: Begin by populating the "Annual Inventory Plan" sheet with projected demand based on market research, sales forecasts, and initial product offerings. Use historical data from pre-launch testing if available.
2. Set Safety Stock & Reorder Points: Adjust safety stock values based on supplier reliability and lead times. These are crucial for startups to avoid cash flow strain due to overstocking or operational delays from shortages.
3. Daily Operations: Update the "Current Inventory Ledger" after every receipt, shipment, or physical count. Use barcode scanners (if available) to automate item ID entry.
4. Replenishment: When inventory falls below the reorder point, create a new purchase order in Sheet 3 and track it through status updates.
5. Monthly Review: Review the "Dashboard" each month to analyze KPIs. Use charts to spot trends and adjust forecasts for the next year.

Example Rows

Recommended Charts & Dashboards (Sheet 4)

• Balanced Bar Chart: Monthly inventory value vs. forecasted demand.
• Pie Chart: Inventory breakdown by category (e.g., Finished Goods vs. Raw Materials).
• Trend Line Chart: Inventory turnover over time – shows efficiency improvements across quarters.
• Gauge Meter: Visual indicator for % of safety stock compliance across all SKUs.
