Is it possible to use different billing rates for different clients on a bucket method project?

It is not possible to bill different clients with different billing rates on a bucket method project. However as a workaround, make use of Roles & Rates and assign different client specific roles and rates to the team members of the project. To achieve this, follow the steps given below:

• Create roles based on the client billing rate.
• Assign these newly created roles to the project.
• Select the appropriate role rate while entering Time on the timesheet, based on the client selected.
