A multiple billing rate is a temporary indirect cost rate that applies to a specific period and is used for funding, interim reimbursement, and reporting indirect costs on federal or federal pass-through awards while a final rate is being established. If a team member has multiple responsibilities, assigning multiple rates may be essential. For example, John Smith is a project manager who also does HTML coding, and you'll need to charge him differently based on the type of job he's performing. In this example, you may construct separate jobs for Project Management and HTML coding, each with its own rate, and assign both to John.
