Minimum Inventory is the minumum amount of inventory desired to have on hand after all orders have been filled. The value is used to create purchase orders with the 'Certificates to Order' option. The certificates to order option will create a purchase order that includes all certificates needed to fill unfilled orders and also the amount needed to return the inventory back to the minimum amount desired. Example: If XYZ Store's current inventory is $100, minimum inventory $250 and there are $1000 in unfilled XYZ Store certificates ordered, the certificates to order purchase order will recommend purchasing $1150 ($1000 to fill orders and $150 to return the inventory back to $250).
