ACOSS (Agence centrale des organismes de sécurité sociale) is the central umbrella body for the network of local offices responsible for collecting social security contributions (URSSAF). It also manages the flow of funds and cash flows within the social security system. Though not directly involved in administering benefits, ACOSS and the URSSAF are at the very centre of innovations such as exemptions to stimulate employment and foster the development of the home help sector.
