If you run your own business, it's important to track expenses and how you are using your time. There's a free timesheet software out there called, duh, Timesheet. Here's a link for you to read some Timesheet success stories. I think this would be a great way to track your projects. Much easier than just keeping an Excel file or writing it on a dry erase board. Though I haven't personally tried it out. Give it a go then tell me what you think! Maybe I'll start using it for my own projects!
