Common Change has done all the work for you! It is certainly possible to set up a bank account and have multiple signatories on the account to be able to maintain fiscal accountability, and then make and respond to needs either in person or via email/text/calls and we know of several groups who have done so. As folks began to express interest in Relational Tithe and collaborative giving over the years we heard people saying that it would be easier for them to do shared giving without having to do all the administrative work that goes into it. We created Common Change as a tool to facilitate giving - creating an easy toolkit for contributing funds, managing finances, making and responding to requests and getting quarterly or annual reports on your sharing. Plus your donations to your Group Fund are tax deductible.
