REGISTERING MY BUSINESS NAME

I read somewhere on this board that I need to register my business name with the city and state where I live in Massachusetts. My question is I am not sure what to call myself as far as a business category. Not even sure why I need to register, since I am not selling any products.

Any suggestions? I just printed up business cards before I knew I had to register and now I’m just hoping the name isn’t taken. Pretty rookie mistake, I know. :help

You need to register if you plan to conduct business in a name other than your own. Entities get filed with the Sec. of State. DBA is done at city/town hall.
