Case Study Template: 5 Parts, 3 Formats, 1 Example
Emily Carter
A case study shows one customer's problem, what they did about it and what changed, told with real numbers and the customer's own words. Sales teams send it to buyers who want proof, marketers publish it for search, and founders pull it into pitch decks. Below is a case study template you can copy, the five components it needs, the three formats it usually ships in, and a complete example.
Direct answer. A case study template has five parts: a customer snapshot, the challenge, the solution, the results with numbers, and a customer quote with a call to action. Lead with a headline that states the result, keep it to 500–1,500 words, and publish it as a web page, a two-page PDF or a short slide deck.
The Case Study Template
Copy this skeleton into a doc. The bracketed prompts tell you what goes in each part.
CASE STUDY: [Customer name]
Headline: [The result, in the customer's terms]
Summary: [Two sentences + 2–3 headline numbers]
AT A GLANCE
Industry: [ ] Size: [ ] Region: [ ] Product used: [ ]
1. THE CUSTOMER
Who they are, what they do, why this story matters.
2. THE CHALLENGE
What was wrong, what it cost, what they tried before.
3. THE SOLUTION
What they chose, why, and how it was rolled out.
4. THE RESULTS
Before → after, with numbers and a time frame.
5. QUOTE + NEXT STEP
"[Quote]" — [Name], [Title], [Company]
[Call to action: book a demo / read more / contact]
The definition behind it is simple. Wikipedia's article on the case study calls it "an in-depth, detailed examination of a particular case (or cases) within a real-world context." A marketing case study keeps that idea, one real case examined closely, and arranges it so a buyer can see themselves in the story.
The 5 Components of a Case Study
Each component answers a question a buyer has while reading. Write them from your customer interview notes in this order.
1. The customer
Two or three sentences on who the customer is: industry, size, location and what they do. Add why their situation is common, so readers in the same position recognize themselves. The at-a-glance box repeats these facts in a scannable sidebar.
2. The challenge
Describe the problem in the customer's terms and, wherever possible, what it cost: hours lost each week, missed revenue, error rates, staff turnover. Mention what they tried before. A challenge with a number makes the result later in the story mean something.
3. The solution
What they chose, why they chose it over the alternatives, and how the rollout went: who was involved, how long it took, what the first weeks looked like. Keep product detail to what mattered for this customer. A case study works as a story; the feature list belongs on the product page.
4. The results
The section readers scan first. Give before-and-after numbers with a time frame: "from 9 hours a week to 2, within the first quarter." Pick the two or three results that matter most to your target buyer and turn them into large callouts. Only publish numbers the customer has confirmed.
5. Quote and next step
A quote from a named person with their title carries more weight than any sentence you write. The best quotes come from the interview, in the customer's own words, and describe a feeling or an outcome. Close with one call to action that suits the format: book a demo on a web page, a contact line on a PDF, a next-step slide in a deck.
How to Write a Case Study in Six Steps
- Pick the right customer. Choose one whose situation matches the buyers you want more of, and who has measurable results.
- Get permission early. Confirm they're happy to be named, and agree on who approves the final draft.
- Interview for 30–45 minutes. Ask about life before, the moment they decided to change, the rollout, and what's different now. Record it, with permission, so quotes are exact.
- Collect the numbers. Ask for before-and-after figures and the time frame. Rounded numbers they can stand behind beat precise ones they can't.
- Write the headline last. Once the results are clear, write a headline that states the main one: "Northpine cut scheduling time by 78%."
- Send for approval. Share the draft with the customer and fix anything they flag before design.
Three Case Study Formats: Web Page, PDF and Slides
The same five parts travel well across formats. What changes is the layout and where the reader meets it.
| Format | Best for | Layout |
|---|---|---|
| Web page | Search traffic, links in sales emails, social posts | Hero headline and results band, then the story sections, quote and CTA |
| PDF, 1–2 pages | Email attachments, procurement packs, print at events | Page 1 tells the story with an at-a-glance sidebar; page 2 holds results, quote and contact |
| Slides, about 6 | Sales calls, webinars, investor and partner pitches | One slide each: title and result, customer, challenge, solution, results, quote and next step |
A web page needs a few extra sentences of context because it gets read cold, by someone who arrived from search. A PDF should stand on its own when forwarded to someone who never saw your website. Slides carry the least text: one idea per slide, with the presenter filling in the story aloud.
Many teams write the PDF first, publish the web page from the same copy, and pull the results and quote into a slide for their sales deck. Writing all three from one approved draft keeps the numbers consistent.
Case Study Example
Here's the template filled in for two fictional companies. It runs about 330 words, a typical length for a two-page PDF.
Case study: Northpine Veterinary Clinics × Tallyhaven (fictional sample)
Headline. Northpine cut weekly scheduling time from 9 hours to 2 across four clinics.
At a glance. Industry: veterinary care. Size: 4 clinics, 62 staff. Region: Pacific Northwest. Product used: Tallyhaven shift scheduling.
The customer. Northpine runs four small-animal clinics with overlapping vet, nurse and front-desk rotas. Each clinic manager built schedules in a shared spreadsheet every Friday.
The challenge. Managers spent a combined 9 hours a week on rotas, and last-minute swaps were handled by group text. Twice in one quarter a clinic opened short-staffed because a swap never reached the spreadsheet. "Friday afternoons were just rota Tetris," says operations lead Dana Ruiz.
The solution. Northpine moved all four clinics to Tallyhaven in three weeks, starting with one pilot clinic. Shift templates were copied from the old spreadsheet, and staff began requesting swaps in the app, where a manager approves them in one tap.
The results. After the first quarter:
- Scheduling time fell from 9 hours a week to 2.
- Short-staffed openings went from 2 per quarter to none.
- 91% of swap requests were approved within four hours.
Quote. "I got my Friday afternoons back, and the team stopped asking who's on tomorrow." — Dana Ruiz, Operations Lead, Northpine Veterinary Clinics
Next step. See how Tallyhaven handles multi-site rotas: book a 20-minute walkthrough.
Notice the shape: the headline gives the result, the challenge includes a cost, and each result has a number and a time frame. The quote does the emotional work so the rest can stay factual.
Write and Design the Case Study With Playyy
Playyy is an AI design agent that writes and lays out a case study as a formatted document, then turns the same content into slides, all on one editable canvas. Paste your interview notes and results, or the filled-in template above, into the AI document generator and ask for a two-page customer case study. It writes the sections with headings, result callouts, a quote block and tables, and you edit any part by chat or directly in the document before exporting a PDF.
For the deck version, give the same content to the presentation maker and ask for a six-slide case study: title and result, customer, challenge, solution, results, and quote with next step. The results become large number callouts or a native chart you can edit, and the deck exports as PPTX or PDF for the sales team.
Brand consistency comes from the brand kit: paste your website URL once and Playyy applies your colors, fonts and logo to the document and the slides, so the case study matches the rest of your sales material. The sales collateral use case shows how case studies, sell sheets, white papers and proposals share one brand kit.
Check every number against what the customer approved before you send it. The AI writes from the figures you give it, so the facts stay yours to verify.
Conclusion
A case study template keeps a customer story to the five parts a buyer looks for: who the customer is, what went wrong, what they did, what changed, and what they say about it. Interview first, collect confirmed numbers, write the headline last, and get approval. Then publish one draft in the format your readers use: a web page for search, a two-page PDF for email, or six slides for the sales call.

Frequently asked questions
A business case study has five components: a customer snapshot (who they are), the challenge they faced, the solution they chose and how it was rolled out, the measured results, and a customer quote with a call to action. Academic case studies use a different five: introduction, background, the case itself, analysis or discussion, and conclusions with recommendations.
