How do you make sure that you get all of your work done on time?
As freelancers, we wear many different hats. In addition to performing our freelancing specialty for the client, we’re also the sales staff, the manager, the support team, and the accountant all rolled into one person.
For many freelancers the project planning tasks that go along with freelancing may seem kind of overwhelming (especially if they’ve never done any project planning). Other freelancers may find that they need to provide the same kind of project plans to their clients that would have been required of them in the corporate world.
Either way, project planning can be a lot of extra work for a freelancer. The project planning task is difficult to handle without good tools to work with.
In this post, I list some project management tools that are either freeware or open source.
I was a little surprised none of the 37signals apps made it into the list, but if you're looking for a project management solution on the cheap, this is a great list.
