I had a project in the past that was simple time clock software. I have redesigned it, and I am going to start charging for it. I wrote the application from scratch, and it was quite a bit of work compared to the original.
It can be found at http://www.sipen.com if you would like to check it out. If anyone can provide feedback, it would be appreciated. It is still in 'beta' basically because there are small bugs I may need to fix. Any input (negative or positive) would be appreciated.
