Overriding Billing Rates
Depending on whether you use user-based billing or time code based billing, either the default bill rate for a user or time code is used while calculating the bill amounts. You can override those rates per project.
To override the default rates, click on a project to open its panel and then click Project Actions ▸ ▸ Billing Rates.
In the above example, Chris Patt's bill rate for the project has been set to $80. As you can see, you can click on the Add button to add a rate, click on the Rate cell to edit a rate, or click on the icon to delete a row which will default the rate for that user back to the default rate.
