When you’re just starting your editing or proofreading career, one of the most common questions is: “How do I build a portfolio when I haven’t had any clients yet?”

Great question—and here’s the good news: You don’t need to wait for someone to pay you before you can start building your portfolio.

Let’s look at what actually counts in a beginner editor’s portfolio (and what doesn’t), so you can start putting your work out there confidently.

What Counts in a Beginner Portfolio

You’re not limited to paid, published work. These are all fair game:

1. Practice Projects

Edited passages from style manual exercises or editing courses? Absolutely. Just be sure to label them clearly as practice edits.

Example: “Line edit of a training excerpt from [course name]”

Check with the course owner first before you share the practice projects as well. As far as I’m aware, the Proofread Anywhere course allows you to share your work on the practice projects, but always double check.

2. Volunteer Work

Ever proofread a friend’s newsletter or edited a blog post for a nonprofit? If it was real content with real stakes, it’s portfolio-worthy.

Tip: Ask permission to use before/after samples or mention it on your site.

3. Beta Reading with Feedback

If you’ve done beta reading with constructive feedback (especially for nonfiction), that shows editorial thinking—even if it wasn’t a “formal” edit. Again, ask the author’s permission before you share these.

4. Your Own Content

Have you written and self-edited blog posts, newsletters, or social media captions? These show your voice, your ability to write clearly, and your ability to self-edit.

Note: This works especially well if you’re focusing on editing content writing or marketing materials.

5. Sample Edits You Created Yourself

Take an excerpt from public domain content and show how you’d edit it. Include the original and a marked-up version to demonstrate your skills. In your marked up version, show how you add editorial comments when you have questions for your clients. Make sure your questions or explanations are clear, concise, and kind.

**What Doesn’t Count**

Some things you should probably leave out:

1. Edits Without Permission

Don’t showcase work from someone else’s manuscript or business unless you’ve been given written permission. Respecting NDAs and client privacy is a must.

2. Unedited Original Work

A portfolio is about showing your editing skills, not your writing alone. If you’re including your own blog post, it should show editing chops too—like side-by-side versions or annotated improvements.

This is your opportunity to give your potential client what kind of edits they can expect to receive from you and what it might be like to work with an editor.

3. Overly Polished Final Versions Without Explanation

If it’s impossible to tell what you did, it won’t showcase your editing. Include before/after comparisons or use Track Changes where possible.

How to Present Your Portfolio Professionally

Label each sample clearly: Was it a course edit? Volunteer work? Self-directed? Say so.
Add context if needed: What kind of edit was it (proofread, copyedit, line edit)? What was your focus? Present it almost like a case study.
Show range: Include different types of content (if you plan to offer multiple services).

You can present your samples as

A PDF download
A private Google Drive folder (with links from your website)
Embedded samples on your website (with screenshots or Track Changes)

Do You Even Need a Portfolio as a New Editor?

Short answer: not always.

When you’re just starting out, it’s easy to believe you must have a polished portfolio to land your first client. But here’s the truth: Many editors start by getting work through word of mouth, networking, or job boards, where samples aren’t always required.

Some clients care more about your qualifications, training, or professionalism than a curated portfolio.

If you’re marketing yourself to small businesses, self-publishing authors, or nonprofits, they may not expect a fancy showcase of work; they just want to know you can help them.

So if the idea of building a portfolio is stressing you out, take a breath. You don’t have to wait until it’s “perfect” (or even until it exists!) before you put yourself out there.

A portfolio becomes more useful once you’re ready to

Raise your rates and attract higher-paying clients who want to see proof of your experience
Specialize in a niche (like nonfiction, marketing content, or academic work) and show examples that match
Build a website where prospective clients can explore your services and get a feel for your style

Until then? Focus on doing good work, building relationships, and saying “yes” to opportunities that help you grow. Your portfolio can (and should) evolve over time.

I have never had a portfolio of samples, as such, but I do have testimonials from my clients that I showcase on my website. Like most new editors, I started with nothing. I asked a former colleague to write a testimonial for me because editing had been part of my job. Other than that, I just asked each new client as they came in. It took time, but now my “portfolio”/testimonial page does a lot of the talking for me.

Final Thoughts

Don’t wait for your “dream client” before you build your portfolio. Use what you’ve got—and label it honestly.

Everyone starts somewhere. The key is to show your process, your eye for detail, and your ability to make content better.
