DBA for S-Corp in New York
When you use a name, different from the official name of your company, you should have the DBA registered. In New York sole proprietorships and general partnerships register DBA with their county clerks, while organized companies (Corporations, LLC, etc) file with the NY Secretary of State.
So if your company is called "Alexis Ventures & Enterprises, Inc." you could register a DBA "AV&E" with the Secretary of State (although not "AV&E, Inc.", as DBA cannot have restricted company identifiers as part of its name). We provide this service here: DNA in NY.
