When it comes to commercial contracts, the phrase "Best Endeavors" is often used to describe the obligations of the parties involved. Essentially, this means that the party in question is required to use all necessary efforts to fulfill the terms of the contract. This is a stricter obligation than what is typically required under a "reasonable endeavors" clause, and is equivalent to the term "best efforts" used in securities markets. In most cases, best endeavors is the preferred term in commercial contracts signed in the United States.Best endeavors is a term used in many commercial contracts. The term imposes on one party the obligation to use its "best efforts" to achieve a particular result. This is a stronger obligation than using "reasonable endeavors," which typically only requires using reasonable care and diligence.The term is often used in contracts related to the sale or purchase of goods or services. For example, a company might agree to use its best efforts to sell a product to a customer. This would require the company to do everything reasonably possible to sell the product. If the company fails to sell the product, it might be liable for breach of contract.Best endeavors is also common in contracts relating to securities.
