ORDER BOOK: According to Entrepreneur.com, more than 400 billion cups of coffee are consumed every year in the United States alone, and "most successful coffeehouses have heavy foot traffic and high-volume sales ... [serving] up to 500 customers per day." You will need to constantly serve coffee to regular customers and be able to attract new clients, since your drinks will likely cost only about $3 or $4 each, in order to break even or make money. Although the cost of the coffee itself is quite low and coffee shops frequently mark up their products significantly, the idea is to achieve volume in your sales.
Starting a coffee shop might sound like fun, but it also involves a lot of hard work. It's important to fully research your business before you begin so you'll know what you're getting into, both in terms of finances and managerial responsibilities.
