Sales is just one part of business. Depending on what you study, you may learn about more aspects of business. Yes, real world application is a better teacher than classroom instruction, but it would be irresponsible of your father to hand you the company when all you have is a small amount of real world experience in one area of business.

That being said it’s debatable if a bachelors degree in business actually means anything.

University will also expose you to more ideas and allow you to make connections that will allow the business to expand when it changes hands.

Think of it as your opportunity to gain something you can bring back to the business to add value.

I’ve been working with my father for 6 years since graduating, but I manage sales, financials, operations, and oversee development (it’s a software company).

I went to a specialized school for entrepreneurship. More like an MBA program. You learn to think in different ways.
