B2B case study template, with examples

A B2B case study works when a buyer can see themselves in it within ten seconds. That means a headline with the result, a short snapshot of who the customer is, then the problem, the approach and the outcome, with numbers. Below is a seven-part template, an example of each section done well, and the mistakes that make case studies get skipped.

TL;DR

• Seven parts: headline result, snapshot, challenge, approach, results, quote, next step.

• Lead with the outcome. Buyers skim for the number first.

• Be specific about the "before": the problem is what makes readers recognise themselves.

• If the client can't be named, anonymise properly and keep the details that matter.

The seven-part case study template

1. Headline with the result

The outcome, the customer type and the timeframe. "How a 200-person manufacturer booked 46 meetings with distributors in 90 days." (Illustrative.)

2. Snapshot

A short box with industry, company size, region, the service or product used, and two or three headline numbers. This is what skimmers read.

3. Challenge

What was going wrong, in the customer's words where possible. Include the cost of doing nothing. "Their sales team relied on trade shows, which produced a burst of leads twice a year and silence in between."

4. Approach

What you did, step by step, and why. Name the decisions, not just the activities. "We built a target list of 300 distributors in three new markets and ran role-specific outreach to buying and category managers."

5. Results

Numbers with context: what changed, compared to what, over what period. Use a before-and-after where you can.

6. Quote

One or two sentences from the customer about the result or the experience, with name and role if they agree.

7. Next step

A single, relevant call to action: a similar resource, a call or a related service.

What makes buyers read to the end

• Results above the fold. The headline and snapshot carry the story for skimmers.

• A recognisable problem. The challenge section is where readers decide "that's us".

• Specific numbers. "46 meetings in 90 days" beats "significant growth".

• Honest detail. Mention what was hard. It makes the result believable.

• Visuals. A before-and-after chart or a timeline helps the result land.

Anonymised case studies

Many B2B clients won't allow their name to be used. You can still publish a strong case study:

• Describe the company by industry, size and region instead of name.

• Keep the real numbers, with permission.

• Remove anything that identifies them: logos, product names, exact locations.

• Get written approval for the final version.

Our own case studies follow this approach. See examples such as lead generation for a professional conference.

Common mistakes

• Burying the result at the bottom.

• Vague numbers like "improved efficiency".

• Writing about yourself instead of the customer's problem.

• Too long. 600 to 1,000 words is usually enough.

• No next step. Readers who are interested have nowhere to go.

Where to use case studies

• Sales follow-up: send the most relevant one after a first call.

• Outbound: reference one result in a short message.

• LinkedIn: turn the story into a post or carousel. See LinkedIn post ideas.

• Landing pages: add the headline result near your call to action.

• Proposals: include two that match the buyer's industry. See our proposal templates.
