You can use budgets in Zoho Books to store the ideal amount of money you would like to spend for a project as a whole as well as for individual tasks and staff. You can also store the number of hours you would like to spend for a project. After you’ve set your budget, you can compare the time and cost it actually took versus the amount you set in your budget.
There are four different budgets options available.
Go to the Timesheet tab, select the desired project and click the Edit button.
