If you have a business, it’s important to know when to use its legal name. Example: If your business’s name is “My Business LLC”, you must refer to your company as “My Business, LLC” in contracts, just as you signed it up within the formation documents with the state.
If you want to refer to your business as “My Business” or “MB” or “Designs By My Business” instead of “My Business, LLC”, you will need to file for a DBA (Doing Business As) with the state. This will ensure that all of your interactions are operating under your business properly. Once you have a DBA filed and approved, you can use this variation of your business name on your invoicing and on social media profiles, for example.
