Unlike a typical new start up, a franchise has already dealt with the problems that any new busness will encounter, and those problems have been overcome and resolved. When you buy a franchise, what you really are buying is a SYSTEM.
The SYSTEM is a proven way of doing all of the things that any business must do to be successful. That system has been tested, adjusted, perfected and proven over time by the FRANCHISOR. The Franchisor is now offering you a DUPLICATE OF THAT SUCCESSFUL BUSINESS MODEL as your new business.
So, contrary to what you might be thinking, you aren't just buying the business idea, or the marketing, or the image . . . . what you really are buying is the best way of doing that business - a proven way. It has ALREADY WORKED, which really increases the likelihood that it will work for you.
One of the best things about a franchse business model is that it ASSUMES THAT YOU KNOW NOTHING about setting up and running this particlular business, so the SYSTEM contains all of the necessary components of the business model. "SOUP to NUTS" . . . "Business in a BOX". Turn KEY. You don't NEED TO KNOW ANYTHING because the SYSTEM knows everything. You simply "apply the system".
Think of it like this . . .
A McDonalds franchisee doesn't need to know ANYTHING about how to make hamburgers or fries. The SYSTEM KNOWS HOW. The franchisee is buying the COMPLETE FRANCHISE SYSTEM that includes all of the components necessary to successfully produce a duplicate of every other successful McDonalds. That's the whole point of the franchise model.
And that's why FRANCHISING is the most successful business model of all time.
