Case Study Writing Service

Your customers are more convincing than you are

You can tell potential customers that you’re knowledgeable, reliable, responsive and very good at what you do. They’d probably rather hear it from someone who’s already paid you.

That’s what makes a good case study so useful. Instead of another marketing claim, it gives prospective customers a real example of the problem you were asked to solve, what you did and what happened as a result.

The familiar structure is challenge, solution, result. The difficult bit is finding the story worth putting inside it.

I’ve been writing professionally for 30 years, with a background in journalism as well as corporate and commercial copywriting. I interview customers and subject-matter experts, find the useful details and turn successful projects into clear, credible case studies that demonstrate what you can do without reading like 1,000 words of self-congratulation.

The interesting bit usually isn’t in the brief

A project brief might tell me that the implementation was successful, the customer was delighted and the new system delivered significant efficiencies.

That’s a start.

But what was happening before? Why was it a problem? How serious was it? What had they already tried? Why did they choose you? What happened during implementation? Was anything unexpectedly difficult? What actually changed afterwards?

And what does “significant” mean?

That’s why I prefer to interview the people involved.

My journalism background taught me how to prepare for an interview, ask open questions, listen properly and recognise when something in an answer deserves another question. A questionnaire can collect information. A conversation can uncover a story.

Challenge. Solution. Result. That’s the easy bit. Most business case studies follow roughly the same structure for a good reason. There was a situation or problem. Something was done about it. Things changed. But a structure isn’t a story.

The challenge needs enough context for the reader to understand why it mattered. The solution needs to explain what you actually did rather than becoming a list of product features. And the result needs to demonstrate a meaningful difference.

Sometimes there’s another useful ingredient: friction.

Perhaps the implementation wasn’t entirely straightforward. Perhaps circumstances changed halfway through. Perhaps there was an obstacle that needed solving. Removing every difficulty can make a case study sound less convincing rather than more.

Real projects tend to have edges.

Let the customer do some of the selling

There’s an important difference between:

We provided an exceptionally responsive service throughout the implementation.

and a customer explaining what happened when they needed help at four o’clock on a Friday afternoon.

Specific experiences are believable.

So are good customer quotations.

I don’t interview people simply to obtain an approving sentence to drop into the finished case study. I want to know what they noticed, what mattered to them and what changed from their point of view.

Their language can also tell us something useful about how customers actually describe the problem you solve. That’s often rather more revealing than the terminology used in the marketing department.

“Successful” isn’t a result

Neither is transformational, highly effective or significant improvement. If useful numbers exist, I want to find them.

Perhaps something that took three days now takes three hours. Costs fell by 17%. Twenty sites were migrated without interruption. Complaints dropped. Capacity increased. An additional process disappeared altogether.

Specifics make a case study credible.

Not every project produces a conveniently dramatic percentage, of course. There may be other evidence: a process simplified, a deadline met, a risk reduced, a capability introduced or a problem that stopped occurring.

I won’t manufacture numbers because they’d look good in a pull quote. The evidence has to belong to the story.

Case studies without the corporate varnish

The temptation with customer success stories is to make everybody look perfect. The client was visionary. The challenge was enormous. The solution was innovative. The implementation was seamless. The results were exceptional.

Everyone involved was apparently magnificent.

Unfortunately, that can make the finished case study sound like advertising dressed up as evidence.

I’d rather make it believable. That means clear language, useful detail, authentic quotations and enough context for somebody reading it to understand why the result matters.

The aim isn’t to make your success smaller. It’s to make it credible enough to count.

One interview can do rather a lot

A detailed customer conversation doesn’t necessarily have to produce one piece of content.

The full story might become a website case study or downloadable PDF. A shorter version could be useful to the sales team. Strong quotations might work on service pages or in presentations. Individual findings could provide material for social posts, proposals or other marketing content.

You don’t have to turn every customer interview into a small publishing empire.

But if we’ve already uncovered good evidence and useful customer insight, it makes sense to consider where else it could earn its keep.

Case study writing services

I can help with individual customer stories or an ongoing programme of case studies, including:

customer and stakeholder interviews;
background research and project familiarisation;
identifying the strongest angle;
B2B and customer case studies;
challenge, solution and results narratives;
customer success stories;
anonymous case studies where appropriate;

editing and rewriting existing case studies; and
adapting case-study material for other marketing content.

I can work directly with your marketing, sales or customer-success team, or alongside your agency.

From introduction to approval

We’ll start with the project itself: who the customer is, what you did for them, what makes the story interesting and anything I need to understand before speaking to them. If an interview is required, you’ll normally make the introduction.

I’ll research the background, prepare the questions and conduct the conversation. I’ll then write the case study, selecting the details and quotations that make the story useful to the intended reader.

You’ll review the draft for accuracy and messaging, and the customer can check their quotations, figures and any information attributed to them before publication.

That approval stage matters. A case study is supposed to provide evidence. It rather defeats the object if the evidence hasn’t been checked by the person providing it.

Thirty years of asking questions

Writing a case study isn’t simply a matter of making the sentences sound good.You have to understand enough about the organisation, project, product and customer to know which details matter.

I’ve spent 30 years interviewing people, researching unfamiliar subjects and turning complicated information into something other people can understand. Journalism taught me not to assume that the first answer is necessarily the interesting one. Commercial writing taught me what to do with it once I’ve found it.

Got a customer story worth telling?

If you’ve got a successful project, a happy customer or a sales team saying “we really ought to have a case study about this”, send me what you have. It doesn’t need to be a finished brief. Tell me who the customer is, what you did and what changed. I’ll ask the questions.

Case study writing FAQs

What do you need from us to write a case study?

Usually, some background on the customer, the project and what you believe makes the story worth telling. Existing proposals, project information, reports or results can all help.If the important information is mostly sitting inside people’s heads, that’s fine too. That’s what the interviews are for.

Do you interview our customers?

Yes. In many cases, that’s the best way to produce a strong case study. I’ll prepare beforehand and conduct the interview as a conversation rather than expecting your customer to complete a lengthy questionnaire.

Do we need measurable results?

They’re extremely useful, but not every worthwhile case study comes with a dramatic percentage attached. We’ll look for the strongest available evidence, whether that’s measurable performance, time or money saved, a change in process, a problem resolved or credible observations from the customer.

Can you write an anonymous case study?

Yes, where there’s enough information to tell a useful story without identifying the customer.

A named customer will usually provide stronger social proof, but confidentiality or commercial sensitivities sometimes make anonymity necessary.

Can you rewrite an existing case study?

Yes. I can restructure or rewrite an existing case study where the underlying story is good but the finished piece is too long, too technical, too promotional or simply doesn’t make enough of the evidence.

Who is responsible for customer approval?

You should ensure that you have the appropriate permission to identify the customer and publish any non-public information. As part of the writing process, I can incorporate customer amendments and ensure approved quotations, figures and factual details are reflected accurately in the final copy.
