SEO Tacking Told - Would you use this?

I am in the process of developing a tracking tool which will allow me to keep a record of all my blasts, link building, web 2.0 properties etc.

I currently use a spread sheet but this has become messy and i want something that will allow me to add all the details of my client and then add all the links i have built, details of all web 2.0 properties including login details etc. The ability to include some/all of this data into a monthly client report would also be a feature.

I also want it to record any paid services I use so that I can track any associated costs.

I will also release this when its finished so just wandering what features you would like to see in this, what would you find useful, what would you pay for something like this, monthly or one off payment?

thanks in advance for your help

what do u currently use to track your projects?

I would never pay for something like this on a monthly basis. 1 time purchase only and the data would have to be on my local system.
