Need help choosing a good combination name. Which one is the best combination of a LLC formation company?

Does LLC required in the name when print on business cards, letter, etc??

There is no 'best' name style, madtomic. It is all down to personal preference. Personally, out of what you list there, I prefer the third, ABCD Network, LLC.

IIRC, LLC is not required on your business literature such as business cards, although your official name does include LLC, so on any official documents that are filed, LLC must be included. I may be mistaken though, and it may well differ from state to state, I'm sure somebody with a little more knowledge about the subject than myself will drop in a comment or two.

I prefer the plural versions. So my vote would be: ABCD Networks, LLC

Not sure about the LLC requirements. Sorry.

http://bizfilings.com/learning/llcfaq.htm#name sums it up well enough.

When I filed, the form had me fill out an entity name and a DBA. I'll assume you know what a DBA is, and suggest that you setup the main name as an LLC and then DBA with whatever you want it to appear as.

please help with the poll fellow wht!

ABCD Networks, LLC - the best one.

AFAIK, you can name your company one of the following:
Something, Limited
Something, Ltd.
Something, LLC
