Your Nonprofit Case for Support: A 5-Step Checklist / Cosmic

Too many social impact leaders step into donor meetings with a bold vision—but an unclear case for why anyone should support it. They see the potential, they know the impact their work could have, but they do a terrible job of getting other people to understand that vision.

Your case for support isn’t just a fundraising tool; it’s a strategic asset that can align your messaging, mobilize your team, and inspire serious investment in your mission. But only if you get it right.

It’s the master narrative that combines your purpose, vision, and strategy into a cohesive story. When done effectively, it becomes the playbook for your fundraising, your marketing, and your management.

Here is a 5-step framework to help you build a clear, compelling case for support that connects with hearts and minds—and opens doors.

Step 1: Establish Your 'Why' (Purpose, Problem, Urgency)

Before anyone can care about your solution, they need to understand why it matters. This first step is the establishing shot for your entire narrative. It sets the context, establishes relevance, and answers the most critical question in a donor’s mind: “Why should I care?” Your ‘Why’ is comprised of three essential elements.

The Purpose

This is the foundational reason your organization exists. What is your fundamental purpose? It’s not just what you do, but why you do it. This should be a clear, concise, and inspiring statement that captures the core of your mission.

The Problem

What specific, tangible problem in the world are you dedicated to solving? Avoid the trap of getting stuck in buzzwords and academic speak. Describe the problem in human terms that anyone can understand. The more clearly and emotionally you can articulate the problem, the more invested your audience will become in finding a solution.

The Urgency

Why is this problem important right now? What are the consequences of inaction? Supporters need to understand what would happen if your vision did not come true. Creating a sense of urgency—without being inauthentic—helps your issue stand out against all the other important problems vying for attention. It frames your work not just as important, but as timely and essential.

Step 2: Paint a Compelling Vision (The Future State)

Once you’ve established the problem, you must offer a compelling vision of the alternative. This is your response to the ‘Why.’ It’s the hopeful, aspirational core of your case for support. If the problem is the current reality, the vision is the future you are working to create.

What Does Success Look Like?

This is the make-or-break ingredient. What is the change you envision? What does the world look like if your organization succeeds? Don't be afraid to be bold. Your vision should be big enough to inspire people and make them feel like they are part of something transformative.

Describe this future state with clarity and emotion. Use storytelling to paint a picture of the lives changed, communities strengthened, and systems transformed. This isn’t about outputs, like the number of workshops held; it’s about outcomes, like a community where every child has the opportunity to thrive. This is what captures the imagination, connects with your audience’s values, and motivates them to join your cause.

Step 3: Outline Your Strategy (The 'How')

If you’ve convinced someone that the problem is urgent and your vision is worth pursuing, their next logical question will be, “How are you going to do that?” Your strategy provides the answer, bridging the gap between the problem and the vision.

Your Unique Approach

This doesn't need to be a schematic-level diagram of your operations. That’s a common mistake that mires your audience in unnecessary detail. Instead, describe your strategy in its purest terms. What is your theory of change? What is your big-picture plan for making your vision a reality?

The Big Picture Plan

Tell a story about your plan. If there's something unique about your approach that makes it particularly effective, highlight it. This is where you build credibility and appeal to the logical side of your supporters’ minds. While emotion inspires, logic convinces. Your strategy must provide a rational foundation that makes your vision feel not just inspiring, but achievable. If it’s missing, people may be motivated by your vision but remain skeptical that your organization can actually pull it off.

Step 4: Build Credibility (The 'Why You?')

You've presented an urgent problem, a compelling vision, and a sound strategy. Now, you have to answer the unspoken question: “Why should I believe you can do this?” Building credibility is about proving your organization is up to the task and is a trustworthy steward of a supporter’s investment.

Showcase Past Wins

Don’t be shy about your accomplishments. Many nonprofits lean too far into humility and miss the chance to build confidence. Brag a little. Celebrate what you’ve achieved, the milestones you’ve hit, and the progress you’ve made. This isn’t arrogance; it’s providing evidence of your effectiveness.

Let others sing your praises. Share testimonials from beneficiaries, quotes from community partners, or endorsements from respected leaders in your field. This type of social proof is incredibly powerful because it comes from a third-party perspective, reinforcing your claims and validating your impact.

Let the Data Speak

Back up your stories with hard evidence. Share key impact metrics that demonstrate your success and show progress toward your vision. Presenting clear, compelling data is not bragging—it’s simply sharing the facts of your impact. Combining powerful stories with verifiable data creates an undeniable case that you are a credible and capable organization worthy of support.

Step 5: Define the Supporter's Role (The Ask)

This is where everything comes together. A huge mistake organizations make is to present the first four steps beautifully, only to end with a vague or absent ask. Don’t leave your audience thinking, “That was interesting, but what do you want from me?”

Center the Donor

The most effective asks shift the focus from “we” to “you.” Frame the supporter as the hero of the story. It isn’t about what your organization needs; it’s about the transformational impact their support can make possible. Use language that empowers them and connects the dots between their contribution and the vision you’ve laid out. Show them exactly how their participation will help achieve the future state they now feel invested in.

Be Clear and Flexible

Your ask must be clear. Whether you’re asking for a specific donation, a volunteer commitment, or an introduction, spell it out. At the same time, be flexible. Tailor your pitch to the individual. Understand what they care about most and connect your work directly to their priorities. If a donor cares deeply about environmental justice, show them how your program advances that cause. If they are passionate about education, highlight that angle.

By inviting supporters to participate on their own terms, you create a genuine partnership and make them a co-creator in your mission.

Your Case for Support is More Than a Fundraising Tool

While traditionally used for fundraising, your case for support is one of the most versatile assets your organization can create. Don’t just file it away to be used for your next capital campaign. Put it to work across your organization.

Use it as a Content Strategy: The five steps—Why, Vision, Strategy, Credibility, and The Ask—are your content pillars for the year. Create blog posts, social media campaigns, and email newsletters based on each ingredient. This ensures your strategic communications are constantly reinforcing your core narrative and planting seeds for future fundraising efforts.
Use it as a Management Tool: A strong case for support is a powerful tool for internal alignment. Share it with your team, your board, and your volunteers to ensure everyone is rowing in the same direction. It provides a shared language and a unified message that can mobilize your entire organization around your most important goals.

If you don’t have a dialed-in case for support, now is the time to create one. It’s a foundational asset that will generate opportunities, clarify your message, and drive results for your organization for years to come.
