Table Structures & Columns (Inventory Data Sheet)

The main table in the Inventory Data sheet is structured as a simple list of products with essential fields: | Column | Description | Data Type | |--------|-------------|-----------| | Product ID | Unique identifier for each product (e.g., P1001) | Text/Number | | Product Name | Full name of the item (e.g., "Wireless Earbuds") | Text | | Category | Department or product type (e.g., Electronics, Apparel) | Text | | Current Stock Level | Number of units currently in inventory (as of today) | Number | | Reorder Point (ROP) | Minimum stock level before placing a new order | Number | | Lead Time (Days) | Average time between placing an order and receiving it | Number | | Avg. Monthly Sales (Last 6 Months) | Average units sold per month over the last six months | Number | | Last Sale Date | Date of the most recent sale recorded for this item | Date | | Forecasted Demand (Next Month) | Automatically calculated forecast based on historical data and trends. Formula applied here. | Number |

Formulas Required

This template uses a set of lightweight, easy-to-understand formulas:

Forecasted Demand (Next Month):
=ROUND(AVERAGEIF(InventoryData!$C$2:$C$100,[@Category], InventoryData!$H$2:$H$100) * 1.1, 0)
This formula calculates the average monthly sales for products in the same category and applies a 10% growth factor (adjustable). The result is rounded to whole numbers.
Reorder Status:
=IF([@Current Stock Level] <= [@Reorder Point], "Order Now", "OK")
Alerts users when inventory falls below the reorder threshold.
Stock Days Remaining:
=IF([@Forecasted Demand (Next Month)] > 0, [@Current Stock Level] / ([@Forecasted Demand (Next Month)] / 30), "N/A")
Estimates how many days of stock are left based on the monthly forecast.

Conditional Formatting

To enhance visual clarity and help users spot critical issues instantly:

Stock Levels Below Reorder Point:
Apply red fill with white text to cells in "Current Stock Level" where the value is less than or equal to the "Reorder Point."
High Forecasted Demand:
Use yellow highlight for forecasted demand values above 2 standard deviations from average (optional advanced rule).
Stock Days Remaining:
Green fill if over 30 days, yellow if between 15–30 days, red if below 15 days.

Instructions for the User

Add Products: Enter product details in the Inventory Data sheet. Use unique Product IDs and set appropriate Reorder Points based on lead time and sales patterns.
Input Historical Sales: For each product, update the "Avg. Monthly Sales (Last 6 Months)" column using data from your past six months of records.
Update Regularly: Re-enter sales figures monthly to keep forecasts accurate. The template automatically recalculates forecasted demand and reorder alerts.
Review Dashboard: Navigate to the Dashboards & Charts sheet weekly to check visualizations of inventory health and trends.
Place Orders: When "Order Now" appears, initiate purchase orders based on forecasted demand and lead time. Use the formula-derived reorder quantity (can be added manually).
Adjust Growth Factor: In cell A1 of the Sales Forecast sheet, you can modify the growth rate (e.g., 1.1 for 10%) to reflect actual business trends.
