To my surprise I just found out that you cannot import quantity on hand from csv/xls when mass importing products! I read a work around somewhere that you have to create an inventory adjustment with all products, then export it with the quantity fields, edit in on excel and import it again. This would definately work with one exception though: when you select "All products" in inventory adjustment, no products are added because they have zero (0) quantity!

So is the only way to manually add all the products in the inventory adjustment and edit their quantities? Please enlighten me here because I must be doing something wrong! There is no way that you can't import your products quantities!
