Marketing teams love case studies because decision-makers always want to see what their competitors are up to. It's a great way for them to hit their conversion KPIs.
Sales reps love them even more because case studies provide cold, hard proof showing how the product or service they're selling overcomes the pain points their prospects want to overcome.
Success stories open doors. So, what would you write about? The answer may be surprising...
Case studies don't have to be blockbuster wins. They can be everyday niggles your product or service solves. To find your own hero story, look for three things: a problem that frustrated your client, a smart way you solved it, and a result they’re still benefiting from.
To show you what we mean, here are nine examples of these stories in action:
A CRM platform found that few trial users were converting because the software felt "confusing". Your content team built a daily tip email service and added a series of helpful "how-to" articles to their website. This approach guided new users through the initial learning curve, doubling their conversion rate to paid accounts in eight weeks.
A consulting firm's sales team kept seeing promising proposals go quiet after the initial pitch. To fix this, your enablement specialists rewrote their sales deck, added an objection-handling sheet, and created a simple follow-up playbook. Fewer deals went cold, and the team's close rate jumped by 20% in just three months.
A building firm seemd to be in constant disputes with clients over what work had been completed. Your QA consultant solved this by sitting in on site reviews, introducing clear evidence trails, and adding mandatory mid-phase sign-offs. Disagreements dropped to almost zero straight away, and client approvals came through twice as fast.
A private clinic was consistently missing its revenue targets because too many patients were failing to show up or cancelling late. Your healthtech team implemented an automated SMS reminder system and gave patients the ability to reschedule their appointments online. Within a single quarter, missed appointment slots fell by 60%, and overall appointment volume rose significantly.
For months, a food manufacturer was getting complaints from major retailers about inconsistent product quality. Your procurement team addressed this by rewriting supplier agreements and training goods-in staff to perform simple visual quality checks. This simple change cut waste by 20% and stopped complaints from their key accounts virtually overnight.
An investment firm's complex identity verification system was creating a major bottleneck that slowed down new customer onboarding. Your compliance consultants tackled the problem by simplifying the required forms, introducing ID scans, and automating the approval workflow. The changes reduced the average activation time for a new client from several days to under an hour.
Losing new users in the first week is a common problem for language apps. After your EdTech team found learners were put off by the intense focus on grammar, you rejigged the lesson order to prioritise vocabulary and added gamification for motivation. The result was a sharp and immediate fall in the app's user drop-off rate.
A UK firm wanted to expand into the EU, but their shipments were constantly being delayed at customs. Your trade consultancy stepped in to rewrite the client's paperwork, retrain their operations staff, and simplify the entire customs workflow. This cleared the backlog, meaning the firm to hit its target export volumes within the first month.
An enterprise SaaS provider failed an internal audit after staff were found to have admin access to old client accounts. Your security team responded by rebuilding the platform's admin control features from scratch and retraining all the team leaders on the new protocols. As a result, the company passed its follow-up emergency audit with ease.
Saving staff time, cutting down on costs, fixing inefficiencies all make great case studies. Let us turn your hero stories into case studies your sales and marketing teams can use.
To find your hero stories, we speak with your sales and support teams about what buyers care about the most. Which features close a deal? Which features do customer services help with the most?
We ask you to identify the customers on your CRM using the services clients value the most. We then ask your sales and support teams to recommend which customers we should get in touch with.
We contact each client on your shortlist. We speak to as many as we can to get a deeper understanding of each feature: how easy they are to use, the problems they solve and the gains they deliver.
You get our shortlist with selection based on each client's quotability, line of business and the level of difference your product made. We’ll create short testimonials from clients we don’t feature.
We write each case study using this copywriting formula: the problem, why it mattered, how the client found your product, how you tailored it to solve their problem and the results they achieved.
We deliver a variety of different case study formats (more in the next section) for different teams including an SEO-optimised version for your site, social posts, PDF downloadables and more.
We send the drafts to both you and your client for review. We'll keep revising it until you and your client are happy with the messaging, tone and content and are ready to sign it off as complete.
When you and your client have signed the case study off, we provide you with the final versions, ready to drop into proposals and follow-ups, website landing pages and more with no rewrites needed.
You don’t just get a case study. You get these six different versions that your sales and marketing teams can use to drive inbound leads, follow up with prospects and show how your product solves real problems for real customers.
We write a search-optimised web page version of the case study. It includes clear copy, internal links and smart metadata to help bring the right visitors to your site.
Short posts for LinkedIn and X highlight the problem solved and the outcome you've delivered. Each one links to the case study on your site to drive new enquiries.
You get a clean, branded PDF that’s easy to drop into sales decks, email replies and proposals, showing how your product solves real problems in the real world.
A one-page summary that highlights the client’s challenge, your solution and the end result. It’s built for fast use in prospecting emails and pitch packs.
We write a short email that introduces the case study and links to the website version. You can send it as-is or adapt the intro for your next newsletter.
We use Vocal Video to capture your client’s story on camera. You get a sharp, branded clip to use on your website, at events or in outbound campaigns.
We take care of everything from first call to final sign-off, so your team gets sales-ready content they can actually use.
After reading a case study, buyers often check the professionals that carried out the work. A well-written About page and clear team bios help them understand what you do and the expertise of your people. It's the last check-up many buyers do before making the call.
Case studies show what you've done. Thought leadership content shows you how approach business. When decision-makers are at or near the point of buying, there's more chance they'll call you if they trust you and regularly check in to get your opinion on industry issues.
Here's a selection of the types of questions customers ask when they contact us.
A good case study writer takes a real customer success story and turns it into a clear, compelling narrative that shows how a product solved a specific problem. It’s a way to turn past wins into proof — giving future buyers a reason to trust what the business offers. Companies hire professional writers to handle interviews, write the story, and produce polished sales assets without tying up internal teams.
What’s involved in writing a case study?
Why case studies matter
They handle the whole process of writing a case study, from interviewing a happy customer to delivering polished sales and marketing assets that tell the story clearly and credibly.
To show real, measurable results that a client achieved using a product or service. It’s practical proof that builds trust with future buyers.
Three parties usually take part in creating case studies: the business commissioning the project, the client whose story is featured, and the specialist writer who runs the process and creates the final content.
Case study projects usually start with a scoping call. The writer meets with sales or customer success teams to surface strong, success-driven stories worth telling.
They look for four things: good results that other clients would want to achieve, a relevant client profile, someone who’s willing to take part, and ideally, someone who can offer memorable quotes.
The writer runs a 45–60 minute recorded call to understand the client’s original challenge, their buying journey, and the results they’ve seen. It’s relaxed but structured to get strong material.
Writers often turn one story into several formats, such as:
A single case study typically costs between £1,500 and £5,000 depending on how complex the story is and how many deliverables are included.
From kickoff to final sign-off, most case study projects take four to six weeks, depending on client availability and review cycles.
The writer shares a draft of the case study with both the business and the featured client, manages all feedback, and makes revisions until everyone’s happy with the final version. At that point, the project is over.
Case studies give sales reps something real to share, a proven example of success that helps answer common client objections and strengthens proposals by proving solutions work in the real world.
When used as gated downloads or optimised web content, case studies attract high-interest visitors and encourage them to share their details.
Yes. Once the business makes an introduction, the writer handles the rest, from scheduling the interview for the case study to following up for approvals.
If the story doesn’t stretch into a full piece, the writer can still extract shorter testimonials or quotes for use on your website or in other marketing.
Before writing a case study, they review existing content, brand guidelines, and marketing assets. Revisions are used to fine-tune the tone until it feels right.
Writers often use remote testimonial tools like Vocal Video, Testimonial.to or Vouch. These platforms guide the client through a simple recording process that captures their story on camera.
Most writers charge 50% upfront to start the project, with the remaining 50% due on completion once the final assets are delivered. Deposits are necessary because of the time-consuming nature of a case study project.
An effective commercial case study describes how a product, service or process offers a solution to a problem experienced by individuals or businesses. Good case studies also provide new insights into the subject matter being covered. That could be how the product, service, or process achieves it: for example, a workflow automation or a new approach to a regulatory obstacle.
Firms use case studies in their digital marketing campaigns. Their aim is to boost brand credibility by showing how the product works in practice and drive revenue by generating more leads. They work well because they are, in effect, customer stories with happy endings. Potential customers read them and see how you help firms overcome issues similar to theirs in other companies.
Essential for effective case studies is a structured, compelling narrative that moves the reader from background, challenges, resolutions and implementation to the final result. They also showcase the emotional and human aspect of the journey a client's been through: for example, how a product, service or process helped them solve the problem and the benefits that brings.
For better storytelling, visuals can highlight the important points in a case study. The case study should also be written in clear, persuasive, and concise language, helping your audience better understand the value of the product and service.
Freelance writers can handle all types of case study needs across various industries. Their skill comes in complex case studies where multiple decision-makers and departments are responsible for the final outcome and buying decision. The more complex your product, service or process, the more you need a freelance case study writer with proven expertise and a strong track record.
Successful case studies typically include client interviews to gather relevant data and testimonials. This can involve collecting data from different real-world use cases, not just surface-level observations.
This means they'll need to be comfortable with interviewing as interviewing current clients is really important for understanding the challenges, needs and obstacles of a client in a case study. They should also be able to gather data not just from interviews but from observations and primary and secondary sources.
