Inventory items columns

I want to make some amendments to the inventory items table, for example, I want to change the title of quantity on hand to be quantity sold.
how can I reach to this option?

not possible.
also, Qty on hand is not sold quantity because the quantity represents the inventory stock available with you.

so as you mentioned there is some thing wrong in the program, because when i register any sales, the sold items appear under the column of quantity on hand, and the balance will appear under the column of quantity owned.

@Tamer_Derbala There is nothing wrong with the program in this regard. You may be entering transactions incorrectly or have accounts set up incorrectly. To understand inventory management in Manager, read the three-part Guide beginning here:
