Pointkit is an online project collaboration service targeted to contractors, freelancers and small teams. It comes with many features including, task managing, invoicing, and time tracking. I built Pointkit using Pointkit itself to keep on track of all the many web development tasks required to build it.
Pointkit is now in Beta mode at Pointkit.com. You can sign and test it for free.

Once all the main bugs are eliminated there will be a premium account plan which will cost $19 a month and will include all the options.
I like to keep options simple so PointKit will only have two plans, the free one with limited options, and the paid one with all the options.
