At a glance
The parts of a case study, and what each one must do
| Part | What it answers | What usually goes wrong |
|---|---|---|
| Headline | What changed, and for whom? | A company name and nothing else |
| The customer | Is this company like mine? | No size, sector or situation given |
| The challenge | Do they understand my problem? | Vague pain, with no cost or consequence |
| What was done | What would happen in my project? | A product list instead of a story |
| The result | Did it work? | Adjectives where the numbers should be |
| The quote | Would they recommend it? | A line nobody would say aloud |

Case Study Writing Services: questions buyers ask
What is a case study writing service?
A case study writing service interviews your customer, gathers the facts and figures, and writes the story of how your product or service solved a real problem. The finished case study usually covers the customer, the challenge, what was done and the measured result, and the customer approves it before it is published.
How much does a case study cost?
It depends on how many interviews are needed and which versions you want. We quote per case study or for a set, in writing, after a short call. Projects start from $550.
Do you interview our customer?
Yes. We prepare the questions, run a short recorded call and send the customer the draft for approval before anything is published.
What if our customer will not be named?
An anonymous case study can still be useful if it gives the sector, the size and real numbers. We will tell you honestly when a story is too thin to publish.
What if we do not have exact numbers?
We help you find them, in analytics, the CRM or the customer's own records. If a result was not measured, we say what was done and state no number.
How long should a case study be?
Most work well at 600 to 1,200 words on the web page, with a short version for sales emails. Length matters less than a clear result.
How long does it take?
The proposal sets the dates. Most of the time goes on arranging interviews and waiting for the customer's approval. The writing itself takes days.
Can you turn one case study into other content?
Yes. One good story can become a sales slide, a short video script, a post for your company page and a section of a proposal.
