Manuscript Editing
Thoughtful, professional editing for fiction and nonfiction.
Every manuscript deserves an editor who understands both the finer points of language and the bigger picture of effective storytelling. I offer developmental editing, line editing, copyediting, and proofreading to help authors strengthen their work while preserving their unique voice.
I also partner with independent publishers and editorial agencies to provide reliable, detail-oriented manuscript editing for their clients.
Business Writing & Editing
Clear, compelling content that connects with your audience.
From educational articles and product reviews to technical content and white papers, I help businesses communicate complex ideas, engage readers, and establish credibility.
With experience spanning pet care, health technology, consumer products, and more, I bring research skills, adaptability, and editorial precision to every assignment.
Experience You Can Count On
Good writing is about more than finding the right words. It’s about understanding the audience, communicating with purpose, and paying attention to the details.
I’m Sara Seitz, a professional freelance writer, editor, and novelist. Since founding Pen&Post in 2019, I’ve worked with publishers, businesses, and digital publications to create and refine content across a wide range of subjects and formats.

Whether I’m refining a fiction manuscript or translating technical information into accessible content, I approach every project with curiosity, care, and a commitment to quality.
Many of my client relationships have lasted for years, built on consistent communication, dependable work, and a willingness to adapt to each client’s needs.

Great editorial work is often a collaborative effort. I work with publishers, editorial agencies, and businesses that need a dependable freelance professional to support their projects and maintain high standards of quality.

I value clear communication, thoughtful feedback, consistent quality, and the kind of professional relationships that make working together easy.
