It is very easy to use, learn it by yourself if you have some business background.. or you could take a course from Algonquin, I think they offer the course.
I have one QuickBooks, I don't remember the version. If you are interested in that, I'll check and tell you. By the way, I bought the book from teh book store last year.
QuickBook is an accounting software which designed for non-professinal people(people who has basic business knowledge).It is pretty straight forward, as XYZ139 said. I think you will be fine.If you are in rush, say have an interview rencently, just let me know see what I can do for you.
