'Inc.' means 'incorporated' and 'LLC' means 'limited liability company.' This refers to the legal form the business operates under.

Thanks Arim for the link, I learned alot. One more thing Is there any difference between INC. and Corporation?

Inc. and corporation are the same. Most businesses use 'inc.' because it is shorter. Businesses that are structured as a corporation or an LLC are required to indicate that information in their business name. Therefore, it is much easier to say 'XYZ Inc.' rather than 'XYZ Corporation' or 'XYZ Limited Liability Company.'

Inc stands for incorporated, which means the business is set up as a corporation in their state (or Delaware or Nevada). LLC stands for limited liability company. Corporations are owned by shareholders, whereas LLC's are owned by members.The form of a business tells us how the owners share liability. Shareholders of a corporation share almost no liability for the actions of the business. Members of a LLC share someliability (but nota lot) for the actions of the business. So, for example, if your vendor is incorporated, then you know you cannot sue the owners personally for breaching your contract. On the other hand, if you vendor is an LLC, then you may be able to sue the owners personally for breaching your contract. I hope that helps. SM.
