Who decides the rankings on this site?
Big Impact Books writes and publishes The Authority Book Desk, so its team decides the rankings. Every option is judged on the same stated criteria for one reader, a busy CEO or attorney, and the site does not present itself as independent.
The criteria we use
Whether price is published
Published prices are quoted exactly with their source. Where none is published, we say so.
What is included
Whether editing, publishing, and promotion are part of the service or separate.
Author time
How much of the author’s time the provider states. Where nothing is stated, we say so.
Rules we follow
- We never invent prices, ratings, reviews, or client results.
- We describe other providers only with neutral facts from their own public pages.
- We quote statistics with their source, date, and conditions, and mark older figures as historical.
- Testimonials are quoted from Big Impact Books clients as they appear on its main website.
- Each page shows a Last updated date that changes only when the content changes.

Common questions
Which is better, a proposal coach or a done-for-you publisher?
A proposal coach suits authors who want a traditional deal and plan to do the writing themselves. A done-for-you publisher such as Big Impact Books suits busy CEOs and attorneys who want the book written, published, and promoted for about one hour a week. Our comparison page ranks four options on the same criteria.

Rather than naming companies, look for warning signs: unclear pricing, pressure to buy add-ons, contracts that hold your rights for long periods, vague bestseller promises, and no finished books to show. Get the contract in writing, check who owns the files and the ISBN, and ask to speak with past authors.
