If you work on computers you need to track your screen time.. billing will be a real headache if not!!
I have tried quite a few of these time trackers [such as slimtimer], but this one in particular I really like.
The clients are imported from mac “Address Book” and include all the necessary contact information to add automatically to invoices and estimates… Very cool.
Its not free, but can be used for a very reasonable price.
Slimtimer is suited to a team environment. Track your sub-contractors screen time.
I used this software everyday for a couple years. It’s a great low profile tool that you can have in the background. It’s free as well!
One advantage Slimtimer has over native time tracking apps, it’s light weight.
You can accuratly track a number of developers simultaniously with this website. Allowing you to mine development time and productivity very effectively.
I found Billings more suited to the type of work I am doing now. I noticed a jump in productivity with my time tracking and invoicing workflow. Also these guys are near my hometown!
