They cannot deliver what they promise Yes, AMZ Pro Hub can "publish your book on Amazon and Google as a paper and ebook edition. That's what they CAN do. What they CANNOT do is everything else they promise. They make it sound like they are very tied into the latest and greatest trends and techniques for e-marketing and publicizing, but they are absolutely inept. For starters, they will offer a "guaranteed or your money back" publishing deal in which they assure you they can sell lots of books. For me, after 18 months, they cannot take credit for selling a single copy. I am responsible for all online sales (about 40) which took place as I taught several workshops and classes. The contract promised a webpage; they wanted me to pay extra for that. I refused and they charged my credit card anyway. I threw a fit and they reversed the charges and produced the webpage as promised. After a year of no sales, they stopped all activity and refused to return my texts and calls. ProHub promises unlimited editing and revisions. Beware. Without telling me, the ran my text through an AI editor that changed text, punctuation, quotes!, capitalization, and so on. They did not tell me they did that. I caught it AFTER the book went live. They had to take it down while I went over the text line by line to fix as many problems as I could find. Why did they do that? Because ProHub's content writers have terrible English skills and are incapable of offering any kind of worthwhile editing feedback regarding style or content. I wanted to produce the print edition first, but they produced an ebook edition first, which made formatting the print edition almost impossible. ProHub editors/staff have no sense of style or elegance and will produce ugly copy. The writer must pay attention to proper pagination, page numbering, running headers, TOC layout, everything. The first cover layout had spelling errors. The first print edition had the book cover upside down. The second edition had been secretly re-edited as mentioned. The third effort had lost the correct pagination. ProHub will produce marketing materials (blurbs and blogs) that are so badly written they made little sense. I had to rewrite all of them myself. I finally had to take over the task of writing the blogs for them. The advert blurbs got much better over time, but I suspect they were using ChatGPT or similar. They wrote their own "reader reviews" for the webpage that were blatantly from ProHub due to the recognizably poor language they used. Summary: They will promise the moon and deliver nothing. I saw ZERO evidence of sales from their side. They claim to not know how many books have been sold on Amazon, so how were they going to live up to the contract of $10,000 in royalties if they had NO IDEA how many books were sold? So, shop around and be wary of all publishers that make huge promises and who do not use their real names or locations. By the way, ProHub will also shuttle you from one project manager to another about every 6 months and ask for extensions on the contract they can avoid meeting their promises. For transparency, I am a non-fiction science writer. My first book was published through large and well-known publisher that sells a lot of books, but royalties were $1 per book and limited to about the first year of sales (they sold the ebook copyright and I got about $2000.) I wanted to go to online sales with this book to increase royalties and to lower the price of the book. In other words, I wanted a bit more control. Working with ProHub without doing my homework was a rookie mistake. Don't make it.
