There is a wide range of contracts that need to be used in the course of doing business, often dependent on the nature of your business and the country in which you are operating.
Before starting any commercial negotiations, it is a good practice to enter into a Confidentiality Agreement, also known as a Non-Disclosure Agreement (NDA), with businesses to whom you may be disclosing sensitive information. It gives you the ability to take legal action if the other party discloses the information to a third party without your consent.
A legal agreement for the sale of goods or supply of services helps to make your customers aware of their rights and obligations from the moment you start doing business with them.
If you are selling goods, you will need a Sale of Goods Agreement (Business to Business). It typically covers the description of what is to be bought, the price, and practical details such as delivery time and returns.
Use a Supply of Services Agreement when one business provides services to another. This agreement describes the scope of services provided as well as the service levels, the fees to be paid, and how to terminate the agreement.
