The Euclid Network has launched a consultation on the European Commission's financial regulations.
Filippo Addarii, director of the European network for third sector leaders, said the commission had decided not to consult publicly on the regulations, which govern all its grants and tenders.
But Euclid had been invited by the commission's Directorate-General for Budget to advise it on how to make the regulations more sector-friendly, he said.
Euclid, which is affiliated to UK chief executives body Acevo, will consult its members and other national and international networks to compile a list of 10 recommendations. Addarii said he hoped these would make EU funding more accessible and flexible and address issues such as full cost recovery.
"This could have a dramatic benefit for the development of civil society and its relationship with the EU," he said. "My message is to get in touch because Euclid won't achieve anything on its own. If we don't succeed now we won't have another chance until 2014."
