Hi,
We can track almost all the costs & revenue related to the project with an analytic account.
Go to Accounting-> Settings-> Tick Analytic Accounts.

By analytic accounting over project management, we can track its performance, productivity, profitability, invoicing, and timesheets in all manner.

For more details, refer to the blog:

Hope it helps
