Becoming a food vendor is a good way to work on your own schedule, set your own hours and be your own boss. At first glance, the concept of a vending cart or concession stand may seem like a simple venture. But as with any other business startup, there is some real work involved.

Developing a business plan, creating a menu and choosing the right equipment and supplies are just a few things that you have to think about before getting your idea off the ground.
