The document will be available next year and will pull together all the key points of good practice that were discussed during the meeting.
Gregor McNie, public affairs manager at the Institute of Fundraising Scotland, said it could lead to the development of a new code of fundraising practice.
"We are taking things one stage at a time, but eventually it should be a possibility," he said.
"What the institute eventually produces will be a strong, clear and workable guide to best practice in cross-border fundraising that enjoys sector-wide support."
The discussions covered transparency in fundraising, how fundraising organisations make donors aware of their geographical remit, how gifts received from outside a charity's area of operation should be treated and how fundraised income is divided up between the four nations during UK-wide campaigns or corporate partnerships.
The guide will be produced with reference to the institute's code Accountability and Transparency in Fundraising and in consultation with the ImpACT Coalition before being taken to the wider sector.
The group is to meet again to develop key actions.
