&gt; You are right, a few good tools out there. This is just our take on it, we like simple things :)<p>I used to have a really simple way to track time, back in the pre-cloud days: music CDs.<p>Put on CD, hit play, start working on something billable to a particular client. When the CD ends, put on another. When done working on stuff for that client, add up the total time of the pile of played CDs, and that&#x27;s the time to bill that client.<p>That did require manual action, but since I was going to listen to music while I worked anyway it was not really any extra work.
