My unit price (stock value / level) constantly changes each time I add more stock. I know purchase price is visible on the inventory screen but it would be a lot more useful for me to have unit price visible as this is the magical number used to quote customers and put your margin on. I have put a support ticket in about this and linnworks have advised as this is constantly changing they cannot add it to the inventory screen however it is a simply calculation of stock value / level so I would not have though it would be such a big task.
