Phew. I just got done working on invoicing my clients for the month. I have one client I've done a large number of different small projects for and it took almost a half hour just to figure out exactly everything I've done (looking over all of the plans, etc.). Then I went away from the computer for a few minutes and… it was all gone. So I had to tally it all back up again.
At any rate, it's nice to get that done. One conscientious client actually asked me the other day when I was going to bill him. Now, I've almost got an entire free week unless any other projects come up… maybe I can get some of my pet projects done!
