Table Structures and Columns
The template features multiple structured tables, each serving a distinct purpose in the startup’s inventory planning lifecycle:
1. Inventory Tracking Table (in "Inventory Tracking" sheet)
| Column | Data Type | Description |
|---|---|---|
| Date | Date/Time (YYYY-MM-DD) | Transaction date (e.g., receipt, shipment, internal transfer). |
| Item ID | <Text/Number | Unique identifier for each product or inventory item. |
| Description | Text | Name and brief description of the item (e.g., “USB-C Charging Cable - Black”). |
| Category | <Text/List (Dropdown) | Select from predefined categories like "Electronics," "Packaging," "Raw Materials." |
| Initial Quantity | Numeric (Integer) | Opening stock at the start of the period. |
| Received | Numeric (Integer) | Units received from suppliers or production. |
| Issued/Used | <Numeric (Integer) | Units consumed, shipped, or used in fulfillment. |
| Final Quantity | Numeric (Integer) | Automatically calculated as: Initial + Received – Issued. |
| Unit Cost ($) | Decimal (2 decimal places) | Average cost per unit. |

2. Demand Forecasting Table
| Column | Data Type | Description |
|---|---|---|
| Item ID | Text/Number | Links to inventory items. |
| Description | Text (Auto-filled) | Name of item. |
| Last Quarter Forecasted Demand | Numeric (Integer) | Expected demand for the previous quarter. |
| This Quarter Forecasted Demand | Numeric (Integer, Formula-driven) | Auto-calculated based on trend or growth rate input. |
| Actual Demand | Numeric (Integer) | Entered after quarter ends for variance analysis. |
| Variance (%) | Numeric (Percentage format) | =(Actual - Forecast) / Forecast × 100. Negative = under-forecast, Positive = over-forecast. |
Formulas Required
The template leverages dynamic formulas to reduce manual work and ensure accuracy:
=IF(DATE(Year, Quarter*3-2, 1) < TODAY(), "Completed", "In Progress")– To flag which quarter is active.=B4 + C4 - D4– For calculating Final Quantity in the Inventory Tracking table.=E4 * F4– For Total Value calculation.=Forecast(1, ActualDemandRange, ForecastedDemandRange)– Linear regression model for demand forecasting (if enabled).=IF(VariancePercent > 15%, "High Variance", IF(VariancePercent < -10%, "Low Demand", "On Track"))– Risk categorization.
Conditional Formatting
To enhance visual analysis and quick decision-making, the template includes:
- High Stock Alert: Cells in “Final Quantity” turn red if > 150% of average usage.
- Stockout Risk: Background turns yellow if Final Quantity is below 20% of average quarterly demand.
- Variance Alert: “Variance (%)” cells turn red if > 15% or green if < -10%, indicating forecast accuracy issues.
- Due for Reorder: Items with Final Quantity ≤ Reorder Point trigger a blue highlight.
User Instructions
- Setup Phase: Begin by filling in the “Inventory Tracking” sheet with current inventory levels as of the first day of Quarter 1.
- Quarterly Planning: At the start of each new quarter, update forecasted demand based on sales data, marketing plans, and seasonality.
