Hi Jason, 

Your question relates to a very niche group. Normally, I would say that a BA would not get involved in this sort of work, unless they actually were a Finance Analyst. In that case, assuming he company already exists, the tools they use would have been pre-selected outside of the BAs sphere of influence. 

I'd be surprised if you get much more of an in depth answer though - not on here anyway. I would suggest for such information that you try a board around setting up companies, who are more likely to have relevant experience with such areas.
