Yeah, which is a shame for good apps like FreshBooks and probably Tiempo that handle the other heavy lifting like invoicing but don’t play nice with a day/week workflow.
What are the differences that you see between a day/week workflow and an hourly one?
Tracking by the hour (or less) introduces a whole new level of mental overhead. Most people are pretty good at recalling the major items they worked on in a day -- and if they can't, they can usually reconstruct what happened by examining e-mail history, commit logs, work product, etc. It's a lot harder to recall how many hours you spent on something though. Based on personal experience at least, if I'm not actively using a timer or using some kind of software that records what I'm doing in real time, my personal recollection tends to be way off. Even when I am using a timer, I often run into issues like forgetting to turn off the timer when I take a gym or coffee break.
There's also all sorts of performance anxiety when it comes to hourly tracking. Not all hours are equal. I'm personally way more productive in the morning than I am right after lunch. But as far as invoicing goes, an hour's an hour. So I can either feel guilty about billing two hours for something that should have taken only one or I can write an hour off, which introduces even more overhead. With daily or weekly billing, a lot of that gets smoothed out.
