I've been billing daily but yeah, in my limited consulting experience hourly is way more stressful and it isn't practical to have to account for your work at that level of granularity. Especially since this is a question specifically about long term work.

That being said, this question is more useful as an hourly rate since some people set their daily/weekly rate different because they work more or less than an 8 hour day / 40 hour week.

I make a half day the minimal billable unit for support of old projects. This helps control the problem of odd hours popping up here and there.

For companies that send you around the place internationally, I charge full days for international travel time - giving them the choice of sending you Business or Economy (and the corresponding amount of work that would be possible to undertake in flight).

EDIT: Re the last point - If they are paying by the hour/day/week, they are buying my time irrespective of whether I am able to work or not. Eg If they put me on economy, or put me through a day of meetings - they are going to be charged the day.

I'm not 100% clear on your last point, are you saying that if the send you Business-class you'll be able to get some amount of work done on the plane that you won't if Economy? I'm not arguing here, just trying to understand.

Can we speak a little more as to how you indicate that a half day is the minimal billable unit? My clients are happy to pay my high rate but I can't imagine ever suggesting to them that anything but an hour would be the minimal unit at this point.
