The best sales material most businesses own is sitting in their inbox: a client writing "you saved us" or "we've never had a month like this". It gets a smile, then it gets archived.
A short case study turns that email into proof a stranger can trust. Problem, what you did, what changed, in the client's own words. This prompt writes it from the email and a few notes about the job.
How to use it
- Ask the client first: "Would you mind if we shared your message and the results on our website?" Most people are flattered.
- Paste their message, plus a few lines on the job: what was wrong, what you did, how long it took, and any numbers you can back up.
- Use the long version on your website, the short one in proposals and the three-line version on social media.

Write a case study from the material below. Our business: [name], [what we do] Client: [name or "a roofing company in Ottawa" if they prefer to stay anonymous], [industry] The problem before: [what was wrong, in plain words] What we did: [steps, tools, timeline] Results we can back up: [numbers, dates, or "no numbers, only feedback"] The client's message (paste exactly): [paste] Write three versions: 1. Website case study (250 to 350 words): a headline built on the result, "The problem", "What we did", "The result", and a pull quote from the client's message. End with one line inviting similar businesses to get in touch. 2. Proposal snippet (80 words): problem, action, result, one short quote. 3. Social post (under 60 words) with a hook first line. Rules: keep the client's words as they wrote them (trim only). Never invent numbers, timelines or quotes. No hype words like "revolutionary" or "game-changing". Canadian English.
What makes a case study believable
- Specific beats impressive. "Booked 14 jobs in the first month" is stronger than "massive growth".
- The client's words carry the weight. Quote them, lightly trimmed, never rewritten into marketing language.
- Show the before. Readers recognise themselves in the problem, not in the result.
Only publish numbers you can show, and only with the client's permission. If they prefer, use their first name and industry instead of the company name.
