Thank you for the quick response.  I understand the concept of FIFO.  I actually carry very little inventory, but instead order an item as needed and sell it.  For this item I was able to correct the issue by changing the date of the invoice which preceded the bill (inventory increase).  However, I have another situation that also had the invoice date prior to the bill, but changing the Invoice date did not correct the issue.  To be clear I had none of these items in stock as seen in the picture below. The last ones I sold were in Oct of 23. 

So why is QB adjusting the cost?
