I got tired of filling out timecards so I wrote a simple script to print out my timecard for me (I still double-checked and signed it). Word got around and I added some features to default to your hours/billing numbers from the previous week for people other departments. It was really cool walking past the timecard tray every week and seeing it evolve from the pile of yellow cardstock timecards with a few folded white paper ones (printed from my script) to eventually almost entirely printed ones. It was something that just took me a few hours on a slow week, and probably ended up saving the company quite a lot of time.

Now that I'm doing contracting work, I did the same thing again when I got tired of invoicing from a spreadsheet. Not that generating an invoice is all that hard or time consuming, it's just one of those tasks that takes me a lot of inertia to start, so I would put it off. I'll probably clean up and post the invoicing script on github one of these days.
