Best of 2009: Web tool

[I'm participating in Gwen Bell's Best of 2009 Blog Challenge, in case you're all like, what's with the theme?]

Web tool. It came into your work flow this year and now you couldn’t live without it. It has simplified or improved your online experience.

Hands down, it’s Freshbooks. Their tagline is accurate. They make billing painless! It’s a very intuitive tool, super-easy to use, and very reasonably priced. Bonus: their staff is unbelievably pleasant. Almost too good to be true, yes. But true all the same. J’adore Freshbooks and their awesome team.
