Overseas Special Interest Group

OSSIG is a networking group for finance staff in international NGOs, based in the UK. The remit of the group is to look at all financial issues that are specific to people working in charities with overseas operations. It provides the opportunity for less experienced charities to learn from those with more experience in relevant areas. In addition charities can identify and share best practice approaches to common difficulties act together on any areas of shared interest.

mangoOSSIG is run by CFG in collaboration with Mango.

There is an active Steering Committee led by Mango and CFG with representatives from OSSIG member charities. 


The group meets three or four times per year in London. Meetings involve case studies from those working in the field as well as sector specialists, and provide opportunities for breakout group discussions. Visit our events pages to see details of upcoming OSSIG meetings and to register your attendance.
