Hi,
I have a custom_field [cost of goods]/[purchase price] for each product.
I would like to give my sales agent comission based on net profit (sales price subtracted by purchase price).
Example:
Product X cost = 100:-
Product X sold = 110:-
Agent comission = 1%
Agent should earn 0.1:- (1% of 10:-) rather than 1.1:- (1% of 110:-).
Is it possible? If not, then this feature is of no real use to me.
