I was at a law firm the other day listening to three attorneys debate whether their spreadsheets were a satisfactory tool for doing their transactional clients' capitalization tables. The first attorney (we'll call her Susan) said that her spreadsheets were fine. Her stock plan administration worksheets rolled up automatically into a few other worksheets for a client's capitalization tables and those worksheets could show the data by class, type, date, and fully-diluted.
It all sounded very complicated, but I was impressed.
