Your Expression of Interest (EOI) might be the most important document you ever learned how to write. While everyone focuses on mastering full grant proposals, EOIs quietly determine which organisations get invited to submit those proposals in the first place. These deceptively simple documents serve as gatekeepers to millions in funding opportunities, yet most people approach them with the same casual attention they'd give to a cover letter.
The harsh reality is that poorly written EOIs eliminate more potentially successful organisations from funding consideration than any other factor in the grant process. Funders use these documents to cut their applicant pool from hundreds to dozens before the real competition even begins. Master the art of compelling EOI writing, and you'll find yourself invited to apply for grants that others never even hear about.
Expression of Interest documents serve a specific purpose that most writers completely misunderstand. They're not mini-proposals or detailed project descriptions. They're screening tools that help funders identify which organisations have the potential to deliver exceptional results with their investment. This distinction changes everything about how you should approach EOI writing.
Funders reviewing EOIs are asking themselves three critical questions about every submission:
Your EOI succeeds when it provides clear, confident answers to all three questions without wasting words on irrelevant details.
The most effective EOIs demonstrate competence rather than just describing intentions. Instead of explaining what you want to do, you show why you're uniquely qualified to do it successfully. This immediately separates your submission from the majority that read like wish lists rather than capability statements.
Successful EOIs follow a structure that builds credibility while maintaining focus. Your opening paragraph should clearly state what you're proposing and why it matters, but more importantly, it should establish your credibility to deliver results. This isn't about organisational history or mission statements. It's about demonstrating relevant expertise and capacity for the specific opportunity at hand.
Your project description needs to be precise and results-focused. Funders don't want to know every detail of your methodology or implementation timeline. They want to understand the logic behind your approach and your confidence in achieving meaningful outcomes. The best EOIs describe projects in terms of the changes they'll create rather than the activities they'll include.
The capacity section of your EOI carries enormous weight in funder decision-making. This is where you prove you can handle their investment responsibly and effectively. Focus on specific examples of similar work you've completed successfully, emphasising measurable results and lessons learned. Generic organisational capabilities matter less than demonstrated experience with comparable projects and challenges.
Your budget summary should be realistic and well-reasoned without being detailed. Funders want to see that you understand the true costs of your proposed work and can manage resources efficiently. Unrealistic budgets signal poor planning or unrealistic expectations about project scope.
The most fatal EOI mistake is treating it like a full proposal in miniature. Organisations try to cram comprehensive project details, extensive background information, and complete budget breakdowns into documents that should be focused and strategic. This approach overwhelms reviewers and suggests you don't understand the EOI's purpose in the funding process.
Another common error is failing to address the specific opportunity you're responding to. Generic EOIs that could apply to multiple funders or opportunities immediately signal that you haven't done your homework about what this particular funder values or needs. Customisation doesn't mean rewriting everything, but it does mean demonstrating a clear understanding of the funder's priorities and how your work advances them.
Many organisations also underestimate the importance of demonstrating readiness. Funders want to invest in projects that can begin immediately and deliver results within reasonable timeframes. EOIs that suggest extensive planning phases, uncertain partnerships, or undefined implementation details raise red flags about organisational capacity and project viability.
Outstanding EOIs go beyond meeting basic requirements to demonstrate why funding your organisation represents the best possible investment. This differentiation comes from showing specific advantages you bring to the work rather than just proving you're qualified to attempt it.
The most compelling EOIs include evidence of innovation or unique approaches that could achieve superior results. This means demonstrating thoughtful adaptation of proven methods to specific contexts or populations. Funders appreciate organisations that combine evidence-based approaches with creative problem-solving.
Partnerships and collaborations can provide significant competitive advantages when presented strategically. Rather than listing every potential partner, focus on relationships that genuinely strengthen your capacity or extend your reach in meaningful ways. Quality partnerships signal that other organisations trust you enough to work closely with you.
Results from previous work provide the most powerful differentiation, especially when those results exceed typical outcomes for similar projects. Concrete evidence of exceptional performance helps funders visualise what you might accomplish with their support.
Writing compelling EOIs requires understanding both the funder's perspective and the strategic purpose these documents serve in the larger funding ecosystem. The organisations that master this skill gain access to funding opportunities that remain invisible to others.
