To start a business, you must narrow your ideas, determine goals and plans to achieve them. Develop a business plan, get training, choose a location, and find financing. Decide on a legal structure like sole proprietorship or partnership. Register your business name and get a tax ID number. Enroll in state and local taxes, get licenses and permits, hire employees, and advertise your new business using various methods. Over time, look for ways to expand your business through partnerships or new campaigns.
