Inventory stock and reorder tracker

What does this template do?

Roll stock balances forward from opening units, receipts, and issues, then compare closing stock with a minimum and target.

Closing units equals opening plus receipts less issues. Reorder quantity equals target less closing stock, floored at zero, only when closing stock is below the minimum.

All quantities in a row use the same unit. Minimum and target levels are manual policies; this worksheet does not calculate demand variability or purchase lead time.

The working tab keeps editable inputs separate from formulas, with room for 60 records. The Notes tab explains the method and how to extend the range. All example records are fictional and can be replaced. Download a workbook format to retain formulas, or CSV when you need calculated values only.
