The Association of Charity Shops is considering setting up an online database of government funding schemes for charities that run shops.
The database would initially contain details of grants or contracts for organisations that provide career training for young people, but it could be extended to include details of other funds.
The Government is already paying the NCVO £1.6m over three years to operate Funding Central, a website that lists thousands of contracting and funding opportunities.
Warren Alexander, chief executive of the ACS, said: "Many heads of retail in charities don't think about applying for government grants or contracts. But there are plenty of funds they could be eligible for.
"Some of the bigger government funding databases are wide-ranging. This would be targeted specifically at charities with high-street shops."
He said he hoped a working party to discuss the idea would be in place by late April.
