Web contractor for mid-sized NPO here. Staff wants contributions of a certain amount to effect a contact's membership. For example, annual membership is $100 a year, Bob has a membership and makes a contribution for $150. The idea is to make the $150 contribution count towards Bob's membership by automatically renewing it for 1 year based on the donation amount.
Is there a solution "out there" for this? Is there a reason to caution against this idea?
