Billable vs. Non-billable

Bill everything to client or only requested tasks?

I'm curious about how others handle the billable vs. non-billable question. We charge clients by the hour vs. a flat fee or marketing up media. Thus accounting for how hours are spent is crucial.

What exactly is your question? Are you asking if you charge non-billable time as billable hours to a client?
