Following an update of ScheduleInterpreter® enabling active time periods (ATP) structure for customer accounts, this update brings similar functionality for the interpreters. Upgrade brings ATP in configuration of the mileage rates for vendors. New features include options to setup default rate for the entire organization and fine tune rates per individual interpreter, when needed. ScheduleInterpreter® preserves the history of the rates and allows to set future rates when federal government announces the upcoming changes. New tools to manage W-2 employees and 1099-MISC independent contractors are added.
