Funding and Service Agreements (FSAs) and Service Documents (SDs) are binding documents between SWD as a funder and the service operators. Both parties are required to observe the terms of respective agreements for different services as laid down in the documents.

 These documents define the obligations of SWD to service operators, the role of SWD in overseeing the performance of the service operators, the kind of services to be provided, the performance standards, and the basis of subvention.
