I work with Sage version 8 and do not use any office plug-ins. I think the idea is that if you have data on spread sheets you can import it in to Sage without having to manually re-type it all. Also you can then export your data back in to your spread sheet or reports in to your word processor. Standard Sage reports tend to print in a very small letter size and it is easier to enlarge and layout you info. in Word.
