Acevo has secured grant funding of £123,000 to disseminate a template that helps voluntary organisations calculate the full cost of projects.
The template, which was first launched a year ago, is intended to help charities get full cost recovery from local authorities and grant funders.
The new funding means that Acevo will produce a concise version of the template for smaller charities, an interactive electronic version, and run a training course to explain how to use it in 35 locations nationwide.
The full cost recovery project is backed by money from the Community Fund, the Active Communities Directorate, and the Northern Rock Foundation.
Other partners in the project are New Philanthropy Capital and KPMG.
Barbara Frost, vice-chairwoman of Acevo, said: "We've made huge progress with the full cost recovery agenda, which is beginning to gain increasing acceptance from government."
Acevo has also set up a commission of inquiry to develop its proposal for a Voluntary Finance Initiative (VFI). The concept, which envisages 10 or 20 year contracts for public service delivery by charities, was first outlined by Ed Mayo in the Acevo publication, Replacing the State? in October.
The 12-member commission includes Victor Adebowale, chief executive of Turning Point, and charity commissioner Geraldine Peacock. The vice-chair is former Labour minister Sally Keeble MP.
