Come up with a niche for your juice business. For example, you can focus on selling organic juices, energy juice, juice smoothies or selling bottled juices wholesale.
Write a business plan that includes details about your niche; three-year operating expenses; three-year profit projections; marketing and public relations strategies; analysis of competing businesses; information about potential vendors and selling venues.
Create juice recipes for your business, including flavors that aren't commonly found in grocery stores. A varied menu will give customers an incentive to patronize your business. For example, orange and pineapple juice are common flavors, but watermelon-acai and strawberry-carrot aren't as typical.
Contact your city's health department to find out what permits you need to start a food business. A food enterprise license, food manager certification or food handler permit may be required.
Obtain the licenses required by your state to operate a retail business, such as an Employer Identification Number, assumed name certificate or sales and use tax permit.
Find vendors to buy produce, if you won't be growing your own. Try to buy local to save on transportation costs. Contact farmers markets and growers associations in your area for a list of potential product suppliers.
Secure venues to sell your juice. Options include flea markets, a roadside stand, farmers market, city festival, carnival or fair, or shopping mall food court booth. Alternatively, you can bottle your juice and sell it wholesale to local grocery stores, restaurants, delis, fitness centers and cafes. Doing so will require that you bottle the juices at a licensed facility, such as a food manufacturing plant or commercial kitchen.
Buy wholesale commercial-grade juicers and supplies, such as cups, napkins and utensils, to save money as opposed to paying retail prices.
Market your juice business. Send news releases to local media outlets, sponsor a fitness day or health fair, launch a promotional website or open social networking accounts.
