InerTrak is a time-tracking tool for designers, contract workers, lawyers, or anyone else who works on multiple projects on an hourly basis. It automatically keeps track of the time you spend on different projects thorughout the day; all you do is click to start and stop the timer. A detail view shows the daily totals for each project, with the ability to check off days as they are billed, and add a note to any date. Each project includes an hourly rate (set automatically from client's rate, or set individually). Data views show times and monetary amounts. Easily create an invoice for any project or client, using a template file that you can customize, and automatically mark the days as billed.
