The first step in starting a bill changer or vending machine business is to find a reputable supplier of commercial quality vending machines. You need to decide what type of vending you want to do: soda, snacks, candy, gumballs, or strictly bill changing. Once you have your equipment, you need to find good locations in your area. Look for places with a lot of foot traffic. The more people coming through a location, the better. Once you have picked out a location, approach the owner of the store and let them know you operate a vending machine business in the area. Make a proposal to set up a vending machine in their store, and explain that, as the owner, you will set up the machine and take full responsibility for keeping it stocked and serviced. Let them know that they will make a percentage of the gross sales, between 15 and 33 percent. Set up your machine and start making money! Then you can start the process over again at another location.
