while im making the invoice with details i need a button of net cost when you open that button it has to be like the invoice you created but without the rates of the invoice so you can add the net cost so in this case you have the invoice and the net cost ( net cost should not be shown to the customers at all it is internal issue )
so from the invoice amount and the net cost amount the company can easily know the net profit
the Estimate feature is not very useful i hope to have this feature it will make it very easy for all the companies
please
