It is a meeting of heads with a common intention and is done by offer and acceptance. A match can be shown from words, behaviors and, in some cases, even silence. For example: The manager of company A goes to the manager of company B and asks him to provide a certain number of parts necessary for his product. Director B agrees and they shake him up. It is an agreement, but not a contract. If the two managers sit down and note that A will buy $1,000 worth of B coins and both sign, it is a contract. A contract has the weight of the law behind it, but the agreement may not be. In business law, there are different types of agreements, some of which are part of normal business operations and are intended to protect other companies from adverse legal situations. .
