An inventory tracker in Excel works well for small to mid-size operations that don't need a full warehouse management system. Done right, it gives you a live view of what's in stock, what needs reordering, and what's running low — all in a spreadsheet your whole team can use.
Your Inventory Master List
One row per SKU. Columns: SKU, product name, category, unit of measure, current stock, reorder point, reorder quantity, unit cost, supplier, and last updated date.
The reorder point is the stock level that triggers a reorder — typically enough to cover your average lead time from the supplier. If it takes 5 days to get stock and you sell 20 units per day, your reorder point is 100 units.
Flagging Low Stock
Add a Status column:
=IF(E2<=F2, "REORDER", IF(E2<=F2*1.25, "LOW", "OK"))
Where E2 is current stock and F2 is reorder point. This flags items that need immediate reordering (at or below reorder point) and items getting close (within 25% of the reorder point). Apply conditional formatting: red for REORDER, amber for LOW, green for OK.
Calculating Stock Value
Add a Stock Value column:
=E2*H2
Where E2 is current stock and H2 is unit cost. Sum this column to see total inventory value. Use SUMIF to see value by category:
=SUMIF(C:C, "Electronics", I:I)
Tracking Movements
Add a separate Movements sheet with one row per stock movement: date, SKU, type (In, Out, Adjustment), quantity, and notes. Then use SUMIFS on the master list to calculate current stock from movements rather than entering it manually:
=SUMIFS(Movements!D:D, Movements!B:B, A2, Movements!C:C, "In") - SUMIFS(Movements!D:D, Movements!B:B, A2, Movements!C:C, "Out")
This makes your stock levels dynamic — they update every time a movement is logged.
Reorder Report
Add a filtered view or a separate sheet that shows only items with status REORDER, including the reorder quantity and supplier. This becomes your purchase order input sheet — one place to see exactly what needs to be ordered and from whom.
The Easy Way: Using SheetXAI in Excel
Example 1: You have your product list and stock levels already in the spreadsheet.
"I have an inventory list on Sheet 1 with SKU, product name, current stock, reorder point, and unit cost. Add a status column flagging items that need reordering, calculate stock value by category, and build a reorder report showing only items that need restocking."
SheetXAI reads your data, adds the status logic, calculates values, and builds the reorder report.
Example 2: Your inventory data lives in your ERP or POS system.
"Pull current stock levels from our inventory system and build a tracker showing stock status, items below reorder point, and total inventory value by category."
SheetXAI connects to your system, pulls the data, and builds the full inventory tracker.
