Articles of Organization 
Like  the Corporation, the Limited Liability Company (LLC) also needs a  incorporating statute. It has a slightly different name than the statute  for the corporation but, in principle, its purpose is the same. In it,  the most important data of the founded company are stated. This is  little more than the company's address and the name of the company.
Operating Agreement 
Operating  Agreement is the English term for the partnership agreement of a LLC.  If a LLC is not a single person, it regulates the relationship between  the shareholders. For example, the Operating Agreement defines the  voting rights of the individual shareholders, their respective  percentage ownership in the company, the profit distribution, and  organizational structure of the management.
For forming a LLC, an  Operating Agreement is not required in many U.S. states. As the  founder, the state cannot force anyone to set up a partnership  agreement. However, there are good reasons for doing it. If several  persons form a LLC, it provides contractual security in the interaction  of the individual partners and, by clearly defining the rules, helps to  avoid disputes. With more shareholders in a LLC, the Operating Agreement  should adequately define what happens to the LLC in the event of death  or retirement of a partner. Basically, the LLC dissolves if one of the  partners no longer belongs to it. Corresponding provisions in the  Operating Agreement can change that.
Finally, the Operating  Agreement is important if the founders are planning to do business with  their LLC in Germany. This fact determines the respective competent  German tax authority, and whether the LLC in Germany will be classified  as an individual??partnership??, or as a corporation. In principle, both  are possible and have an impact on the tax payable. The LL C's  Shareholders Agreement can be written with a carefully worded provision  as to a favorable decision of the authorities. For the LLC, this means  saving money.
So that a U.S. company is established as quickly as  possible ALTON assists its clients as needed with all the mentioned  steps to found a Corporation or a LLC. If necessary, ALTON can also  provide its clients, who do not plan any operations in the United  States, with an official business address and Registered Agent. In  addition, ALTON can assist newly-established U.S. companies with other  important steps, such as looking for suitable personnel in the U.S. or  even acquiring commercial and residential real estate.
Relatively early in both the formation of a Limited Liability Company and a Corporation is the choice of a suitable name. The selection is subject to few conditions. For a Limited Liability Company, it must be the name of the company with, for example, “LLC” or L.L.C.”, “LC” or L.C.”, or “Limited Company”, “Limited Liability Company” or, simply, "Limited" or "Ltd." at the end. For a Corporation, an extension, such as “Incorporated" or "Inc.”, or “Corporation” or "Corp." is required.
The company name can not include components such as “bank” or “trust” unless the founder also has received a proper permit for that industry. Of course, the name chosen in the respective state must not have already been assigned to another company. Along the path to establishing a business as a LLC and as a Corporation, further steps differ slightly. We will, therefore, look at the sequence for each of the two business entity forms.
