This is an application primarily intended for lawyers and other legal professionals who have minimum annual billing requirements. The app allows you to enter your annual billing target, a starting number of hours accrued prior to starting to use the program, and daily billed hours. You can also set which days are non-work days (for example, holidays, weekends, vacations, etc.)
The app will then tell you how many hours you need to bill each day to achieve your annual billing requirement.
