In addition to utilizing resources drawn from its own members and from Palestinians in the Diaspora, WA raises funds from the region through support committees and public campaigns. It has been a consistent and responsible source of development funds for Palestinians during a 20-year period that has spanned continuing occupation, political transition, the state-building process and, since the year 2000, the ongoing emergency situation in Palestine.

WA has partnered with the leading funding institutions in the Arab region and globally, including the Arab Fund for Economic and Social Development, Arab Monetary Fund, Arab Bank for Economic Development in Africa (BADEA), Kuwait Fund, Arab Gulf Programme for United Nations Development Organizations (AGFUND), the Islamic Development Bank (IDB), the World Bank, OPEC Fund, and the development agencies of Britain, France, Italy, Saudi Arabia, and Canada. USAID has funded several projects through partnerships with the International Youth Foundation and with the United Palestinian Appeal. WA has also benefited from cooperation and technical assistance from UN agencies such as UNESCO, ESCWA, UNRWA, and foundation grants from the Ford Foundation, and also with support from Welfare Association-UK (WA-UK) from the European Community; Community Fund, Karim Rida Said Foundation; and the Princess Diana Memorial Fund and a number of other U.K. trusts.
