Use The Core, Adapt Your Nonprofit's Story to Multiple Funders
Adapted from my Proposal Builder's Toolkit: There's no magic in writing an effective proposal for funding; neither is there a guarantee in any single method you might choose to do this. But there is a core framework with which to tell your story every time your organization elects to approach a prospective benefactor. Remember: The proposal that's truest to reflecting your organization's credibility, capability and dedication to mission accomplishment is the one you want in the hands of funding decision makers. Such a proposal is likely to stand the best chance of being treated seriously, and in the event it doesn't result in funds, will hold up as a basis for additional efforts.
