No. There is no such option and I can't promise if it can be added. I will check in future updates. Thank you

You already have this option in the system review the screen shot
all i need is on the sales report to be able to view this cost for each item i sell .
even if it means paying for it

That is settings and no where the avg. cost is display. However you can check it in `sam_warehouses_products`. There is plan to show this on list products page for warehouses but it's still not yet done.

Hello I am willing to pay for this for it to show on sales report this is the right place to show it , it becomes meaningful when shown on the sales report . Advise.
On the warehouse report both base cost and average can be shown but may not be used for any meaningful analytics unless combined with sales.
Your product is the best for all products i have seen so far only this issues are pertinent

Hello, Displaying it on the sales report could take sometime as there could be more than 1 costing record for each sale item. I am not sure on how it can be managed there.
