A structure depends on the organization's objectives and strategy . In a centralized structure, the top layer of management has most of the decision making power and has tight control over departments and divisions. In a decentralized structure, the decision making power is distributed and the departments and divisions may have different degrees of independence. A company such as Proctor & Gamble that sells multiple products may organize their structure so that groups are divided according to each product and depending on geographical area as well.
Another plus is the ability of a corporation to raise money. A corporation can sell stock, either common or preferred, to raise funds. Corporations also continue indefinitely, even if one of the shareholders dies, sells the shares or becomes disabled. The corporate structure, however, comes with a number of downsides. A major one is higher costs. Corporations are formed under the laws of each state with its own set of regulations. You will probably need the assistance of an attorney to guide you. In addition, because a corporation must follow more complex rules and regulations than a partnership or sole proprietorship, it requires more accounting and tax preparation services.
