# Using agreements
<a name="agreements-overview"></a>

AWS Marketplace seller agreements are contracts between sellers and buyers for products and services sold on AWS Marketplace. An agreement is formed when a buyer accepts an offer, public or private. Agreements also govern how buyers use a seller's products and services. The topics in this section explain the agreement structure, the types and their statuses, and how to change or *amend* agreements.

AWS is not a party to any agreements.
