compare Powerstore2/Powerstore3 features?

Thanks for bearing with me. I shall purchase the Powerstore3 release in a little over 2 weeks after I ready the Cloud VPS CentOS server I have been modifying lately. I am grumpy from lack of sleep so please forgive my terse and past-clouded perspective.

I do have one last question.
Can you tell me what has been suggested that best dovetails into Powerstore3 to handle all of the taxes withheld of others, the expenses we incur, and the net income upon which we ourselves will be robbed, I mean "taxed"? It is a messy area that I bet has been smoothed out somewhat by Powerstore and by the back-and-forth between Support and Powerstore users.

Any detail of the mechanisms that might interface with the database and if (and how) the relevant data can be accessed-and-pulled into our outside tool (e.g., Quicken, or something like that on our client system)?

Thanks again,
chris

[note: I have never been able to install Powerstore2 yet because the server was hanging us up, and will needing to get the new version w/o ever having gotten to install. That is a contributing headache that motivated my brashness, so, sorry again.]
