Manhour tracks time while you work, automatically selecting from multiple hourly rates and calculating fees due. Manhour features a flexible rate structure: it lets you specify what hourly rates should apply during certain time intervals- so you could charge your regular base hourly rate during office hours, then automatically apply overtime rates for those late night stints… or use a different rate for weekends and holidays. You setup Rate Categories, create Projects you want to time-bill for, then let Manhour do the work of recording billable hours (or minutes.. or seconds…. Manhour lets you set your own billing block size… bill per full half hour… or every 3 seconds… it's your call) and figuring out your fee for you. Hit the 'Start' button when you start work… and 'Pause' when you stop. It's that simple. Did you do some work while away from your Mac? Use Manhour's Log Editor to retroactively add time to your work log, or to subtract time accidentally recorded while doing something not work-related. And when you're done? Print or save (as PDF or portable plain text) nicely-formatted log reports, or export CSV files easily understood by most spreadsheets and other applications. Manhour uses your Mac's system Address Book when assigning clients to projects, avoiding duplication of contact information. View client contact details directly within Manhour's Info Drawer, while editing through Address Book's familiar interface, at the click of a button. You can even hide Manhour's main window and control recording from the status menu bar. We wanted Manhour to complement your workflow as unobtrusively as possible. It doesn't try to do too much, doesn't force you to fill in more details than you need to track your time and fees… it just quietly reckons with time & money while you work, so you spend your time on billable hours, doing great work.
