If you want something that you can customize to some extent, look at "Legal File Management Software", which although usually not cheap, covers all details as may be necessary.
I personally have been using Amicus Attorney for years and record all characters who are a party to a transaction, plus all documentation and a chronological time line with all the communications involved, telephone calls,emails,faxes, etc.
All information being available with a click of the mouse.
Good Luck,
