Whether you're a nonprofit director writing your first grant proposal or a development professional preparing a federal application, this guide walks you through every stage of the process.

Step 1: Research the Right Funders
Before writing a single word, identify funders whose mission aligns with your work. Resources include Grants.gov (federal), Foundation Directory Online (foundations), and state-level grant databases. Look for funders who have previously funded similar organizations.

Step 2: Write a Compelling Letter of Inquiry (LOI)
Most foundations begin with an LOI — a 1-3 page overview of your organization, the problem you solve, your proposed solution, and your budget request. A strong LOI:
• Opens with a compelling one-sentence mission statement
• Cites data to document the need
• Clearly describes your proposed project and expected outcomes
• States the amount requested and how funds will be used

Step 3: Develop the Full Proposal
If invited to submit a full proposal, you'll need: an executive summary, organizational background, problem statement, goals and objectives, program design, evaluation plan, and a detailed budget narrative.

Step 4: Prepare for Federal Grants
Federal applications (HHS, SAMHSA, NIH, DOE) require registration in SAM.gov, a Grants.gov account, and adherence to specific notice requirements. Allow 4-6 months for federal proposals.
