Questions
What is a DBA?
A registered trade name. Your company keeps its legal name and can also do business, advertise and take payment under this one.
Does a DBA protect my name?
No. It doesn't stop anyone else using the name. A trademark does that.
Do I need an LLC to get a DBA?
No. Sole proprietors can register one too. It just doesn't separate your business from your personal assets the way an LLC does.
