I am under Zoho one, integrated CRM and Book. We have one situation is that : 

We can do record Expense for Potential in Zoho Book and but we are unable to run profit report on particular Deals / Sales

Report by specific Potentials ( Deal )  that shows :

- Sales amount by items

- Cost of good sales by items ( if possible ) 

- Expense items

- Profit ( total of all above )

and Report by all potentials ( Deal ) : same with above , but summary row instead of iteams, but show all potentials by duration.
