We may earn a commission if you hire through links on this page, at no extra cost to you. How we choose picks.
A case study shows how a real customer used your product or service and what changed as a result. It is one of the most persuasive types of content for business buyers. Case studies go wrong when results are exaggerated, the customer has not approved the final text, or the story is all about you instead of the customer. This guide helps you publish case studies that are credible and approved.
We are finalizing our shortlist for this service. Until then, the guide below walks you through how to evaluate sellers yourself.

What a good case study package includes
Case study gigs are priced by length and whether interviews are included. Check that the package states:
- Interview with the customer, and with your team if needed.
- Structure: situation, challenge, solution and results.
- Length and formats.
- Quotes taken from real interviews.
- Approval round with the customer.
- Design: included or text only.
- Revisions and delivery time.
Choose customers whose story matches the buyers you want more of. A case study from a similar industry or size is far more convincing to prospects than one from an unrelated business, even if the results were bigger.
Ask the writer to prepare interview questions in advance and share them with the customer. Customers give better answers when they have time to think and check numbers, and they are more comfortable approving a case study built from questions they saw beforehand.
How to brief a case study writer
- The customer and their contact, with permission to interview.
- The project: what you did and when.
- Results with evidence the customer agrees to share.
- Your audience: who will read the case study.
- Format: web page, PDF, slides or all.
- Brand guidelines and examples you like.
Keep the customer at the center. Readers want to see themselves in the story: the problem they recognize and the result they want. Your product should appear as the means, not the hero.
Plan the approval process with the customer early, including who approves, how long it takes and whether their legal or communications team needs to review. Approvals are the most common cause of delays.
What drives the price
- length and number of formats
- interviews and research
- design and layout
- video or audio versions
- approval rounds
- the writer's experience in your industry
If you plan several case studies, ask for a template. Consistent structure and design make them easier to produce and to compare.
Red flags
- Results or quotes invented or exaggerated.
- No plan for customer approval.
- Stories that focus only on your company.
- No interview, only generic text.
- Use of logos or names without permission.
Store the approval email or form with the case study. If a customer later asks, you can show what they agreed to publish.
For turning case studies into sales pages, see our sales copy guide. For your website, read our website content guide, and for design our presentation design guide.
Reuse each case study across your marketing: a web page, a short summary for sales emails, a quote for your homepage and a social post. One approved story can support sales for a long time if you plan these versions from the start.

FAQ
What is the usual structure of a case study?
The customer and their situation, the challenge, why they chose you, what was done, and the results, often with a quote from the customer.
Does the writer interview the customer?
Often, yes. A short interview gives real quotes and details. Arrange it with the customer's permission and share the questions in advance.
Do I need the customer's approval?
Yes. Always get written approval of the final text, the customer's name, logo and any figures before publishing.
What if the customer cannot share numbers?
Use what they can share: time saved, quality improvements, a before-and-after description or a strong quote. Never invent figures.
Which formats work best?
A web page, a PDF for sales teams and a short version for social media. Some case studies also include a video.
