Description  :A company being an artificial person comes into existence through registration. Registration implies the incorporation of the company as a body corporate with the Registrar Of Companies. It is the legal process through which an enterprise obtains recognition as a separate legal identity.
 The registration of a company plays a vital role in the functioning of the company as the registration of a business is not just another financial aspect of the company; rather it’s a long term assurance of its credibility and success.

Further it helps in (a) Promotion & Advertising - Registered businesses gain more publicity in the industry. This is because they have established credibility not only to their clients but to the government and locality in which they support. The existing clients of a registered business will continue to support the company and gear it to its success. The potential clients of the company on the other hand will find that a registered business is more reliable than one that is not. This is because they are aware of the company’s established credibility in the business world.

 (b) Proprietorship - One huge advantage of registration with state and local government is safeguarding your business name. No one else can register a business with that same name.

(c) Guarantee - Customers and clients, especially people you’ve never worked with before, need assurance that you are a legitimate business. A potential client may suspect your business of being a “fly-by-night” operation if your company isn’t properly registered. When a business is on file with the state, it could put your clients at ease when making a decision about whether to spend money with your company.  

Types of Companies –
Public Company – Public Company means a company which is not a private company and has a minimum paid – up capital of five lakhs or such higher paid – up capital, as may be prescribed. Thus, a public company is one in which:

(a) does not restrict the transfer of its shares,(b) does not limit the number of members and (c) can invite or accept deposits from the public.
 Private Company – A private company is a company with private ownership. As a result, it does not need to meet the Securities and Exchange Commission's (SEC) strict filing requirements for public companies. Private companies may issue stock and have shareholders, but their shares do not trade on public exchanges and are not issued through an initial public offering (IPO). In general, the shares of these businesses are less liquid and the values are difficult to determine.
 Limited Liability Partnership - Limited Liability Corporate (LLP) is a body corporate having separate legal identity. In India, LLP is governed by the Limited Liability Partnership Act, 2008. A limited liability partnership (LLP) is a partnership in which some or all partners (depending on the jurisdiction) have limited liabilities. It therefore exhibits elements of partnerships and corporations. In an LLP, one partner is not responsible or liable for another partner's misconduct or negligence. This is an important difference from the traditional unlimited partnership under the Partnership Act 1890 (for the UK), in which each partner has joint and several liability. In an LLP, some partners have a form of limited liability similar to that of the shareholders of a corporation. In some countries, an LLP must also have at least one person known as a "general partner" who has unlimited liability of the company. Unlike corporate shareholders, the partners have the right to manage the business directly. In contrast, corporate shareholders have to elect a board of directors under the laws of various state charters. The board organizes itself (also under the laws of the various state charters) and hires corporate officers who then have as "corporate" individuals the legal responsibility to manage the corporation in the corporation's best interest. A LLP also contains a different level of tax liability from that of a corporation.
