Table Structures and Columns (Inventory Master List)

Data Collection & Formulas in Action

• Auto-Generated Item ID: =CONCATENATE("INV-", TEXT(ROW()-1, "0000")) (in the first row of Inventory Master List).
• Current Quantity (Dynamic): Uses a SUMIF() formula in the Inventory Master List to sum all quantities from the Stock Transactions sheet for each Item ID.
• Status Update: Conditional logic using nested IF and COUNTIF functions to auto-update status based on quantity levels:

=IF([@Current Quantity] < [@Reorder Level], "Low Stock", IF([@Current Quantity] = 0, "Out of Stock", IF([@Status]="Discontinued", "Discontinued", "Active")))

• Inventory Value: =[@Current Quantity] * [@Purchase Price (USD)] to calculate total investment per item.

Conditional Formatting Rules

• Low Stock Items: Highlight cells in the "Current Quantity" column with yellow fill if value is below Reorder Level.
• Out of Stock: Red background for items with zero quantity.
• Overstocked Items: Green highlight when quantity exceeds Maximum Stock Level.
• Reorder Threshold Alerts: Apply color scales to the "Current Quantity" column using data bars to show stock levels visually.

User Instructions for Accurate Data Collection

1. Open the Data Entry Guide sheet first and review dropdown options and field descriptions.
2. In the Stock Transactions sheet, enter new entries daily with accurate date, item ID, quantity, transaction type (In/Out), reason (e.g., "New Shipment", "Internal Use"), and reference number.
3. Use the drop-down lists to avoid typos and ensure consistency.
4. Never manually edit values in the Inventory Master List—changes should come from automated calculations via transaction data.
5. Update the Last Updated Date field only when changes are made to item details.
6. Run monthly audits by comparing calculated totals with physical counts using a pivot table report.
