RepairQ makes it easy to run a Shrinkage Report for any given amount of time.
Under the Reports page, navigate to Inventory, then to Valuation Summary. Change the Date Type field to "Date Updated" and change Status to "Shrinkage". Apply these filters to process the report.
For a more detailed breakdown, simply click on "Detail Report" on the top right of the Reports page after you've applied the filters. This will provide a report with shrinkage detail for each individual inventory item.
