What Do They Mean by “Doing Business As (DBA)”

Sometimes it makes sense for a company to do business under a different name. To do this, the company has to file what’s known as a DBA—an abbreviation for “doing business as.” A DBA is also known as a “fictitious business name,” “trade name,” or “assumed name.” Sole proprietorship’s commonly use DBAs because a sole proprietorship’s official, legal name is simply the name of the owner. A DBA lets them use a real business name.
