Case Study Writing
A case study is proof that your product works for someone who looks like the prospect. Not a testimonial (too short), not a white paper (too abstract), not a blog post (too general). A case study tells a specific story: who the customer is, what problem they had, what they did, and what happened. The numbers carry it. The narrative makes it readable.
The bar: a prospect should finish the case study thinking "that company is like mine, they had my problem, and it worked." If the case study doesn't produce that thought, it failed regardless of how polished it looks.
The 5-Section Structure
Every B2B SaaS case study follows the same skeleton. The reader expects this format.
| Section | Purpose | Length |
|---|---|---|
| 1. Headline + snapshot | Hook with the result. Quick-scan summary | Headline ≤ 15 words. Snapshot: 3-5 bullet points |
| 2. The customer | Who they are, why they matter as a reference | 100-150 words |
| 3. The challenge | The specific problem before your product | 150-250 words |
| 4. The solution | What they implemented, how, and why your product | 200-300 words |
| 5. The results | Quantified outcomes with before/after | 200-300 words |
Total length: 800-1,200 words. Shorter than 800 feels thin. Longer than 1,200 and nobody finishes it. Executives skim. Make every word earn its place.
