You ask whether you should update your "DBA" designation to conform with current business activities.
The answer depends on what you mean by DBA. Officially, a DBA is a formal filing withe a Municipality or County - it is primarily for the benefit of the government entity and the public so they aren't left in the dark in the event of a complaint, lawsuit, etc. There is really no need to conform your DBA to what you do in your business. By contrast, if you simply mean a trade-name (which some refer to as a DBA) then once again there is no need to conform that with your business - although it is a good idea to do so because it will minimize "confusion" in the marketplace. That can come back to bite you.
I hope this information has been helpful. Best of luck.
I agree with Attorney Hedayat. It depends. You'll need to check with your local government and if you need further assistance, contact a lawyer experienced with small business requirements.
My response does not create an attorney-client relationship. I am providing general information only, not legal advice. In responding to questions, I provide competent legal information but am not applying my legal knowledge or skills to resolve or advise on your specific factual circumstances described in the question, such as by proposing a specific course of action (other than asking the user to seek the advice of an attorney licensed to practice in the relevant jurisdiction).
DBA is essentially short form for Doing Business As. It is a way for you to register your name with the state so as to allow people to locate you, the owner, in the event they need to find you. So long as the name is available, you can name your business whatever you like. That being said, it is generally a good idea not to confuse your potential customers as to the goods/services you have to offer. Hope that helps.
