Great typography in business documents

Forums: 

Hi, hi, thrice hi.

New member here, and my first post so here goes. I can find any number of articles about generic typography subjects such as terminology, basics about serifs v sans serifs and the like, and then again I can find lots of detailed tutorials about using software like InDesign, but I can't find any good resources about the combination of typography as applied in document design.

Put another way, I'd be very interested in seeing some examples, guidelines, rules of thumb etc. specifically relating to the design of business documents that are readable and functional but a step away from the dreaded Micro$oft Word template sort of documents.
