use the reorder report
This report should show any item for which quantity on hand has dropped below the configured reorder amount. If the reorder qty is set to 0, then item is not included on the reorder report. You would need to set a reorder quantity of at least 1 for an item to show up. Then, once the quantity on hand equals or drops below the re-order qty, it’ll be on that reorder report. This should save you from having to go looking for items that need reordering.
