How do I go about learning office management on the computer?

My son is starting a family business in the future.I need to learn office management on the computer.I don't have time for school. Is there any place on the internet where I can learn some things or would the library be the best place to go, to teach my self ?

Answer:
If you are going to be offering "terms of sale" - buy now, invoice, and get paid later - this is a good place to start.
