There is a difference between an occupational license, a business license, and registering your business name and entity. Only certain types of professions, such as contractors, barbers, hair stylists, need occupational licenses, which are usually issued at the state level. Business licenses are issued at the local level by your city clerk's office. Some cities license all business activities. Others license only a few types of businesses, so be sure to check. You register your business name and entity type (partnership, LLC, etc.) where you live and conduct business. Since you conduct business over the internet, your office address would be the location of the business.
