The Prevailing Wage setup table is used for tracking and calculating direct labor expenses at a rate that may be different than the normal labor rate of the Installer.
Some government jobs require the installing company to comply with specific pay regulations. In cases such as these, when a job is created, you may assign a Prevailing Wage code to the job on the Job Work Order form; when a User is entering timesheets, they will be able to select the Prevailing Wage rate or the normal installer rate.
