Portfolio Case Study Template
A template for writing client case studies in three parts (challenge, approach, results), with prompts that draw out the details clients care about.
What this is
A three-page template for writing portfolio case studies that help you win clients. It follows Challenge → Approach → Results, with fill-in prompts for the details prospects look for when they evaluate a freelancer.
What is inside
Page 1: The setup
- Client name / industry (anonymised if needed)
- One-line summary of the engagement
- The challenge: what problem they came to you with
- Context: their size, their market, what they’d tried before
Page 2: The work
- Your approach: how you worked, as well as what you delivered
- Main decisions: why you chose this strategy over the alternatives
- Timeline: how long it took from kickoff to results
- Tools and techniques used
Page 3: The results
- Headline metric (the big number)
- Supporting metrics (3-4 secondary outcomes)
- Client quote / testimonial
- What you’d do differently (shows honesty and self-awareness)
How to use it
- Write one case study per major engagement. Three strong ones are enough.
- Lead with the result, because prospects scan for numbers first.
- Get a client quote. Even one sentence makes the case study far more believable.
- Publish it on your website and link to it from your proposals.
