You can try looking at the Item Costing Report as that will give you the costing history on the left side of it.  Otherwise we could write something custom in Crystal but there is not a table that holds the actual unit costs by time frame but we could pull the information by grabbing the cost from the purchase transactions.  Let me know when you are ready to merge companies.  It is definitely not easy but I just helped a client that had 2 Sage companies but they were the same EIN and the new CFO wanted to combine them.  The history doesn't come but we can bring over some order history for easier lookups and the related beginning balances.  The consolidation function you mentioned is more for reporting as it can combine up Mutiple general ledger balances together but again its only balances and not any detail.  [email protected]  

Thank you John for your help.  I will let my boss know and see what he would like to do.
