In Adobe Workfront, custom billing rates for a specific project are handled through project-level billing rate overrides in the project finance area. Adobe documentation explains that billing rates calculate revenue for projects and tasks, and that role billing rates can be overridden for a project or company. For project-specific custom rates, Adobe’s project finance documentation states that a project manager can specify a different billing rate for a job role on a specific project, and Workfront then uses the project-level rate instead of the system-level rate to calculate revenue. The documented steps are to go to the project, open the Billing Rates or Rates > Billing area, and add a new billing rate override for the relevant job role. Project Details > Billing Information is not the documented location for updating custom project billing rate overrides, and Project Settings > Access Levels relates to permissions rather than financial rates. Therefore, the correct answer is C. Project Finances > Override Project-Level Billing Rates .
