I run my own business. My name is my business name. There is no requirement to have a registered business name in MD. My license has my business name as Timothy (Tim) Montoya.
If you had a car wash or some other type of company, then you would need a business name since car washes are not licensed other than the business license.
But you're a "independent contractor" hanging your hat under a brokers roof......... right? The broker sets your deal or split with hm so his rules, right????
