"Part of the challenge in going freelance over the last nine months or so has been keeping careful track of the projects I do, and making sure not only that I remember to send out invoices, but also that I get paid—hopefully, promptly."
I like how Dan Moren organizes his accounts. His setup is pretty neat. It gives me a lot of great ideas and inspiration to do something similar.
