First, you need a unique name for your business. Second, identify the main activity of your business, such as consultancy, cleaning services, or transportation. Third, choose the best business structure for your needs: LLC, Corporation, or Partnership, and decide on the number of partners. Finally, determine your business address, which also defines the state in which you'll register your business. In most cases, your home address can be used as your business address, except for specific cases like car dealerships requiring a showroom.
