A case study is evidence, and evidence that turns out to be decorated is worse than no case study at all. This case study template holds one rule throughout: every result has a before figure, an after figure, a period and a named source, and no quote is written for a client to approve.
Inside the file: client and context written so a reader recognises themselves, the problem with the number that becomes the before figure, what they tried before and why it did not hold, the solution including the part that went wrong, results with before, after, period and source, an approved client quote, and what happens next. You also get a fully filled case study for a fictional manufacturer and an AI prompt that writes yours and lists exactly what you still need from the client. Works in Claude, Claude Code, ChatGPT, Gemini and Copilot.
B2B Customer Interview and Write-up Flow
The template now covers how to write a case study from the interview onward, so the before number, the period and the real quote are collected before anyone drafts.
-
Agreement first: named or anonymised, who approves, and consent to record the call
-
Two interviewees: the champion for the story and the metric owner for the numbers
-
45-minute interview guide: questions mapped to every section of the template, with rules against leading the customer
-
Interview-to-draft prompt: turns your transcript into a draft, pulls word-for-word quotes for approval and lists what you still need from the client
This is an AI template, not a design file: the structure, the example and the prompt that fills it with your evidence, not a PDF layout to style. One purchase, use it on every customer story you publish, pay once, keep forever and no account required.
