The body of law that governs business and commercial transactions is referred to as business law.   Business law falls under the branch of civil law that deals with issues of both private and public statutes.  Under the laws of business, specific operating guidelines are established in order to regulate corporate contracts and hiring practices.  Business laws also regulate the manufacturing and sales of consumer goods and services.
In order to establish a business within the United States, you must follow the laws established for operating a business within your state.  Registering a business involves filing paperwork with the government to obtain certificates, licenses and permits in order to operate legally.  Business registration involves everything from obtaining a tax identification number to naming your business and applying for the appropriate licenses to operate legally.  Business registration is not a one-time activity.  Business laws require that licenses, permits, and many other certificates be renewed annually.  Laws may also require specific inspections that are ongoing throughout the life of the established business.
All businesses require one or more federal, state, or local licenses or permits to operate.  Licenses can vary from a basic operating license to a very specific permit.  The type of license or permit required by law depends upon the type of business is established.  For example, if an individual wants to establish a cabinet manufacturing company, the business will be required to have specific permits related to environmental safety operations.  Regulations vary by industry and the state and location in which they are operating.  It is extremely important to understand and follow the laws established to owning and operating a business.  Failure to comply with licensing and permitting regulations can lead to expensive fines and put a business at risk for liability and risk.
Business laws have been established in the United States to ensure the safety of the operations, management, and goods and services within the country.  The Uniform Commercial Code addresses most aspects of business law.  All 50 states have adopted the rules for transactions within this code.  The types of transactions addressed in the Uniform Commercial Code include sales, leases, negotiable instruments, bank deposits/collections, funds transfers, and letters of credit, and bulk sales, documents of title, investment securities, and secured transactions. 

Business laws are developed to protect the health and safety of the society that they serve.  The laws encompass everything from the name of the company to the appropriate licenses and permits required to operate.  Laws are also established to address the safety and environment in which a business operates.  Careful consideration is given to environmental factors and the welfare of the community when a business is established.  Depending upon the industry, specific laws regulate the operations to ensure the quality of the product that is delivered.  For example, if you establish a restaurant business you must follow the laws for handling food safely, maintaining the cleanliness of the restaurant, and ensuring a safe environment for which your customers and employees can exist.
