The Institute of Chartered Accountants in England and Wales is planning to expand its scheme that offers charities access to free accounting services.
The institute already allows charities to post volunteering opportunities for accountants on its jobs portal, but few organisations have used the service.
Caron Bradshaw, head of charity and the voluntary sector at the institute, said the organisation was talking to voluntary sector umbrella groups about the needs of their members and planned to launch an expanded service next year.
"Many of our members want to do a small amount of voluntary work, but don't want to act as full-time trustees," she said. "A lot of charities could usefully access that help. We don't think the two groups are being brought together effectively.
"We want to create a new site that brings our members together with third sector organisations that need professional services. We want a body of experts that charities can easily draw on."
The institute was also looking into how it could improve accounting standards in the charity sector and was considering the introduction of a new entry-level qualification, Bradshaw said.
