Do you know of a good financial management program like Quicken that runs on Linux?
It's been a long while, but I came within an inch of moving my company accounts into GnuCash. What finally caused me to decide against it was not the program itself (which I was quite enamored of), but rather, due to it's lack of interoperability in my financial environment - At the time, it wasn't capable of online banking with my bank, new payroll rules from my state could not be automatically updated, and most importantly, my bookkeeper and tax guy wouldn't take the time to learn it, so the interface with them was an import/export PIA. Thus I stayed in QB, which I absolutely hated.
However, it's been many years - so assuredly many improvements have occurred... and your needs may be quite different from what mine were at the time...
Let me know if you like it...
