For legal documents, Statements of Work, bids, etc. I've been using latex a lot lately. It has most of the benefits of Markdown but is way more powerful.

I like to write common documents up front then put macros in place of things like "client name" -- then at the top of the file I declare them and it makes for really easy document generation.
