Doing this more than once? Slashit keeps the case study structure as a template, so writing one up is filling in blanks rather than starting from a blank page.
Use this in Slashit AppFree Case Study Generator
Structure a case study around the problem, what you did and the results — with the numbers up front. A case study is the most persuasive page on most freelance and agency sites, and the one most people never get round to writing.

What is the case study generator?
A case study is finished work turned into evidence. It follows a simple structure: the problem the client had, what you did about it, and the results — with the numbers at the top rather than buried at the end. For most freelance and agency websites it is the most persuasive page there is, and the one most people never get round to writing. Prospective clients do not read case studies to admire your process. They read them to find out whether you have solved a problem that looks like theirs. So the problem section does more work than the portfolio images.
How our free case study generator works
Name the client and the work
Client, industry and what you did. A reader recognises themselves in the industry line.
Describe the problem
What was going wrong before you arrived, in the client's terms.
List what you did
One line per action. Decisions, not a task list.
Give the results with numbers
The part that makes it a case study rather than a portfolio entry.
Add a client quote
Optional, but a plain sentence from the client beats any adjective you could write.
What can you use the case study generator for?
A project that went well
Write it up within a fortnight, while the numbers are to hand and the client is still pleased.
A niche you want more of
Publish two case studies in one industry and enquiries from that industry follow.
A proposal that needs backing
Attach the case study closest to the client's problem. It answers 'have you done this before?' before it is asked.
Work you cannot name the client for
'A B2B logistics company' still works. The industry and the numbers carry the argument.
Who uses our free case study generator?
Freelancers
Turn one good project into the page that wins the next three.
Agencies
Build a library of proof, organised by the kind of problem rather than by client name.
Consultants
Show a result rather than describing a method.
SaaS and product teams
Publish customer stories that read like evidence instead of marketing.
Why use the case study generator?
Numbers first
'Sign-ups up 34% in three months' is the reason someone keeps reading. Put it where it will be seen.
Problem-led
Readers are looking for their own situation. The problem section is what makes them recognise it.
Short enough to actually finish
The main reason case studies do not exist is that people plan long ones. This produces a complete short one.
Case study structure, and why each part is there
| Section | Its job |
|---|---|
| Client and industry | Lets the reader recognise themselves |
| The problem | The part prospective clients actually read |
| What you did | Shows judgement, not just activity |
| Results | Turns a story into evidence |
| Client quote | Third-party proof you did not write |
| Next step | Tells an interested reader what to do |
Tips for getting the best results
Get the numbers before you leave the project
Ask for the before figure at the start and the after figure at the end. Chasing data six months later rarely succeeds.
Use the client's words for the problem
What they said in the first call is more convincing than your later summary of it.
Ask for the quote while they are happy
The week after launch. A request three months later gets a polite nothing.
Keep it under 500 words
Enough to be credible, short enough to be read. Long case studies get skimmed for the numbers anyway.
Be honest about the numbers
If you do not have hard figures, describe the outcome plainly. Invented statistics are noticed, and they undo the credibility the page was for.
Frequently asked questions
How long should a case study be?
Three to five hundred words for most service businesses. Long enough to be credible, short enough that the results get read.
What if I do not have hard numbers?
Describe the outcome plainly — faster, fewer support emails, launched on time. Do not invent figures; a vague honest result is worth more than a precise false one.
Do I need the client's permission?
Ask, always. Many clients are happy to be named; some will agree to 'a B2B logistics company'. Check your contract for a confidentiality clause first.
Where should case studies go on my site?
Their own pages, linked from your work or services pages, with the industry and the result in the title. They are usually the strongest pages you have for search.
How do I get a client quote?
Ask in the week after launch, and offer to draft something for them to edit. Most people will not write one from scratch but will happily approve a sentence.
What is the difference between a case study and a portfolio piece?
A portfolio piece shows what you made. A case study shows what changed because of it. The second is what persuades someone to hire you.
