MI Business Search FAQ
How do I name a small business?
Naming a small business is often a do-it-yourself job. Small business startup budgets usually won’t support hiring someone to help name your business. For easy step-by-step instructions on naming your small business, visit our How to Name a Business guide.
How do I come up with a catchy business name?
The first step to naming your business is figuring out what business structure you will use for your new company. After that, you will brainstorm at least 4-5 possible names. The more you brainstorm the better. Once you have some names, you can test the names against best practices, name availability, and state guidelines.

Should you name your business after yourself?
Naming your business after yourself has its benefits. Unless you have a name like John Smith, your name can help you find a .com domain name. If you are coming up with innovative ideas or a new approach, using your name can help create a strong brand.
There are also reasons NOT to name your business after yourself. If you don’t want to be the face and name of your business, it won’t work. If your type of client or customer base would prefer a company name, then you should give them a company name to work with.
If you want your business to someday run on its own, without you working there every day, then you shouldn’t use your name.
Can I sell my trademark or buy someone else’s?
Yes, you can sell or buy a trademark. A trademark is considered intellectual property which means it can be sold like property. It’s important to consult with an attorney before buying or selling intellectual property, especially trademarks.
Is my trademark application public?
Yes, your trademark application, including your personal identification information, is public. By law, your trademark information must be easily searchable by the public.
Where should I buy a domain name?
Our top choice in web hosting and domain registrars is GoDaddy. We like their domain search tool— you can search for the exact name you want or make suggestions based on keywords and available names. There are also several other companies to choose from that will provide a good experience.
Visit GoDaddy to search for domain names.
Can I put the word “company” in my business name?
Yes, you can. Neither the term “company” nor any of its abbreviations has any legal connotations. A company is simply an association of individuals.
Do I have to write “LLC” after my company name?
If you choose to use a limited liability company structure for your new business, most states will require that you use LLC after the name. You can also use the full term limited liability company.
If you are marketing your business, you usually don’t have to use LLC after the name.
