How to Write a Nonprofit Case for Support Donors Actually Read

A case for support is the single most reused document in fundraising. It becomes the grant narrative, the campaign brochure, the board pitch, and the elevator answer. Write it well once, and everything downstream gets easier. Write it poorly, and every ask drags.

Answer four questions in order

Every strong case answers, in this exact sequence: Why this? Why now? Why us? Why this amount? Change the order and the reader gets lost. Skip one and the ask feels premature.

Lead with the problem, not your program

The worst cases open with the organization's founding year. The best open with a specific human problem the reader recognizes. "Last year, 1,400 kids in our county aged out of foster care without a stable adult in their lives." Now the reader is leaning in. Only then do you introduce yourselves.

Use one story, not five

Pick one person whose life illustrates the problem and the solution. Follow them through the whole document. Five stories dilute; one story burns in.

Show the math without hiding behind it

Numbers give donors confidence. They also numb readers. Alternate: story, number, story, number. "For every $2,400, one child gets a year of mentorship." That sentence has done more fundraising than any pie chart ever.

Name what happens if nothing changes

The strongest cases include a paragraph on the cost of inaction. Not doomsday — just honest. Donors give to prevent futures they can picture. Help them picture it.

Make the ask specific

"Your support matters" is not an ask. "$2.4 million over three years to reach 900 more children" is an ask. If you don't name a number and a horizon, you're writing a brochure, not a case.

Test it out loud with five donors

Before it's designed, before it's printed, before a consultant polishes it — read the draft to five current donors. Watch their faces. The parts they interrupt to comment on are the parts that work. The parts they nod politely through are the parts to cut.

Length: shorter than you think

The internal case document can run 8–12 pages. The version you hand a prospective donor should be one page plus a two-page appendix. Nobody is going to read 40 pages of your theory of change. Say the true thing quickly.
