It is important to keep in mind that the 'On Hand' field is calculated based on historical usage, so it does not pull the most recent Inventory Count. The system **pulls prior Inventory Counts** to figure out how much of an item is used for **every $1,000** in Sales. It then takes the most recent Inventory Count, looks to see how much there has been in Sales since that Inventory Count, and subtracts the Usage per $1,000 number from the most recent Inventory Count to theoretically calculate the 'On Hand' values. To work successfully, the items need to appear on **two inventory Counts which are dated a minimum of 45 days apart**. This allows the system to get a good look at usage over a period of time to make that calculation.
