Self-publishing services compared for CEOs, attorneys, and business owners
Last updated: Published by Big Impact Books
Self-publishing services range from free upload platforms, where you do every job yourself, to done-for-you publishers that help you write, publish, and promote the book.
This directory lays out the main self-publishing services side by side on the same criteria: writing help, publishing, marketing, cost, and royalties. It is written for experts who want a book that builds authority, not just a listing on a store. It is published by Big Impact Books, which includes its own service in the comparison and says so on every page.
Short answer
What are the best self-publishing services for a busy expert?
For a CEO, attorney, or business owner who needs help writing, publishing, and promoting a book, a done-for-you service such as Big Impact Books fits best, because it develops the manuscript through guided interviews and adds podcast and media promotion. Authors with a finished, edited manuscript and time to market it should start with a free platform such as Amazon KDP.

Definition
What are self-publishing services?
Self-publishing services help an author bring a book to market while keeping control of it. In this guide from Big Impact Books, they fall into three groups. Platforms such as Amazon KDP let you upload a finished book and sell it. Ebook stores and distributors such as the Smashwords Store sell and deliver files to readers. Done-for-you publishers such as Big Impact Books do the work with you: planning, manuscript development, publishing, and promotion.
The difference that matters most is who does the work. A platform publishes what you give it. A service helps create what you publish.
Numbers
Self-publishing in five published figures
- $13,500: median annual income for indie authors in ALLi's 2025 survey, versus $6,000 to $8,000 for traditionally published authors (Writer Cosmos).
- 70% or 35%: Amazon KDP ebook royalty, 70% for ebooks priced $2.99 to $12.99 and 35% outside that range (Reedsy).
- 68%: Amazon's share of global ebook sales (Reedsy).
- Up to 80%: royalty on Smashwords Store sales (Written Word Media).
- 16.7%: reported compound annual growth rate of the global self-publishing market (Writer Cosmos).
Decision
Which self-publishing service fits you?
Choose a free platform such as Amazon KDP if your manuscript is finished and professionally edited, you enjoy handling the details, and cost matters most.
Choose a done-for-you publisher such as Big Impact Books if your time is the scarce resource, you have expertise but no manuscript, and you want the book to bring in clients, speaking invitations, or media attention. Big Impact Books describes its process as about one hour a week of guided interviews.
Choose a traditional publisher if you want a publisher-led deal and accept giving up some control over timing and rights.

Common questions
See all 43 questions- What are self-publishing services?
- Self-publishing services help an author bring a book to market while keeping control of the work. They range from free do-it-yourself platforms such as Amazon KDP, where you upload files and set the price, to done-for-you companies such as Big Impact Books, which guide the writing, publishing, and promotion. The right choice depends on how much work you want to hand off.
- How much do self-publishing services cost?
- It depends on how much is done for you. Reedsy lists Amazon KDP’s cost to authors as free. Done-for-you services charge for writing support, production, and marketing, and their prices vary widely. Big Impact Books does not publish its fees in the facts used for this guide; the way to get a quote is a call through its contact page.
- How do I publish my book?
- Start by deciding how much help you need. If you have a finished, edited manuscript, a platform such as Amazon KDP lets you upload and publish it yourself. If you need help writing, producing, and promoting, a service such as Big Impact Books can guide the whole process. Either way, plan your marketing before launch.
- What is the difference between a self-publishing platform and a publishing service?
- A platform is a storefront or distribution tool you operate yourself, such as Amazon KDP or the Smashwords Store. A publishing service is a team that does work for you, such as manuscript development, production, and promotion. Many authors use both: a service prepares and markets the book, and a platform sells it to readers.
- Which is better, self-publishing or traditional publishing?
- For most expert authors who want control and speed, self-publishing or an independent publisher is the better fit; traditional publishing fits authors seeking a publisher-led deal. Writer Cosmos cites ALLi data showing indie authors earn a median of $13,500 a year versus $6,000 to $8,000 for traditionally published authors.
- Who should pick a DIY platform instead of a done-for-you service?
- Choose a DIY platform such as Amazon KDP if you already have a finished, professionally edited manuscript, enjoy handling the details, and want the lowest upfront cost. Reedsy lists KDP’s cost to authors as free. A done-for-you service fits better when your time is the scarce resource or you need help writing and promoting.
- What is the first step with Big Impact Books?
- The first step is a conversation. Use the contact page at yourbigimpactbook.com/contact to ask about publishing support for your book. If you are not ready yet, Big Impact Books also offers a free book-planning checklist to help you organize your idea before you commit to anything.
