Most homeowners don`t want others to know how much money they raised when selling their business. The NDA could have a clause to keep this information secret if the potential buyer decides to track the purchase of the business. Some commercial brokers have a separate NDA agreement for secrecy after the sale. Buying and selling businesses usually raises many eyebrows, as the market is an extremely competitive place. When a party decides to buy a business, but doesn`t want its competitors and competitors to learn their secrets, they usually ask for a confidentiality agreement, abbreviated as NDA. In addition, this also means that the seller is required to keep secret all information about the operation of the operation as well as about the trade agreement itself until the expiry of the NDA.
