Parties entering into a long-term cooperation can lay down general agreements in a framework agreement. A framework agreement can relate to different partnerships, e.g. between a service provider like HeadFirst or Between and an independent professional/supplier, but also between a service provider and client.
It may happen that you are asked to sign several framework agreements, e.g. a framework agreement between you and the service provider, but also a framework agreement of a specific client in which the client and the service provider have laid down their mutual agreements.
You can find the covering agreement(s) in your Select profile under the heading Terms and Conditions.
