B2B case study examples: the 7 parts of a good customer story
Last updated: October 20, 2026
What separates a good case study from a weak one is usually not length or design but detail: who, what they were dealing with, what changed, and who says so. Below are the 7 parts of a story, each with a weak and a strong example. The examples use a fictional company.
1. Headline: state the result
The headline is the one line that decides whether the story gets read. Talk about the customer's result, not your product.
Sample Logistics uses our product
Sample Logistics cut proposal turnaround from 2 days to half a day
2. Summary: two sentences
Most readers only read the summary. Fit who they are, the problem and the result into two sentences.
Sample Logistics is a 40-person international freight company. Since preparing quotes in a single screen, the time for a quote to reach the customer has dropped from 2 days to half a day.
3. Customer intro: let readers see themselves
Industry, size and the team involved are enough. The goal is for a prospect to think "that's like us".
Sample Logistics is one of the leading companies in its industry.
Sample Logistics is a 40-person freight company based in Rotterdam. Its 6-person sales team answers hundreds of price requests a month.
4. Situation: the problem in the customer's words
Instead of a general description of the problem, tell a concrete moment the customer lived through.
The company was facing challenges due to inefficient processes.
Prices lived in three separate spreadsheets. In sales manager Anna de Vries's words: "We had to ask three people for every quote; while the customer waited, a competitor had already sent a price."
5. Solution: the work, not the features
Rather than listing your product's features, describe how the customer used it. Readers should be able to picture their own workflow.
Our product offers advanced pricing, reporting and integration features.
The team brought its price sheets into one place. Now when a rep opens a request, they see the current price and send the quote from the same screen.
6. Result: number, period and baseline
If there's a number, give its period and what it's compared with. If there isn't, give a concrete before-and-after example; an invented percentage does more harm than no percentage.
Efficiency increased significantly.
In the first three months, the average time for a quote to reach the customer dropped from 2 days to half a day. The team answers more requests in the same time.
7. Quote: make it clear who said it
The quote is the most-read sentence in the story. Give it with name, title and company; an anonymous quote doesn't persuade.
"Great product, I'd recommend it to anyone." — A customer
"Now we can give the price before the customer hangs up." — Anna de Vries, Sales Manager, Sample Logistics

Common mistakes
- Telling the story around your product instead of the customer.
- Numbers without period or baseline: "40% increase" compared with what, over how long?
- Long intros: the result belongs in the first two sentences.
- Publishing without approval: always show quotes and numbers to the customer.
- Publishing and forgetting: put the story where your sales team actually works.
