Publisher Champ has become an essential part of my author business. I sell across multiple platforms (including direct through Shopify), and having everything pulled together in one place is a huge help—especially for tracking ads, revenue, and day-to-day performance. What really sets it apart is the support. Eiri has been incredibly responsive and thoughtful, and even implemented a feature I needed much faster than I expected. It’s rare to find a tool where the founder not only listens but actually works with you to improve the product. If you’re an author juggling several sales channels or running ads, Publisher Champ is absolutely worth it. It’s already strong, and it keeps getting better.
Brilliant software and incredible customer support. You can send a chat message and a founder will respond within minutes, and they know how this KDP stuff works inside out.
This tool is my eyes to the detailed metric for Amazon royalties, Amazon Ad spend and beyond. I cant imagine using any thing else. Responsiveness to queries is excellent.
An absolute revelation for any author trying to wrangle multiple retailers without spending a ton of time gathering all the data manually. It does take some setup time, but well worth the effort to be able to see all the pretty graphs and find all your sales information in one place. Would give it more than 5 stars if I could!
So helpful - several times a day, I get notifications of book sales. It helps me keep track of my publishing business easily and at a glance.
Works a charm - best data service for KDP that I've used / heard of.
Using it! saves me time going back and forth from amz ads attributions and fb ads. Also royalties per book much easier to see. Very responsive support. Amazing. Hopefully Amazon updates their reporting soon so we can see when orders were placed and shipped. otherwise I won't know how much organic sales we are generating. Or 2 weeks delayed which makes launches hard. But that's on Amazons reporting.
Have been using for my KDP Business Publisher Champ now for several years. Can highly recommend it.
Publisher Champ has completely transformed how I track and manage my book sales. The sleek, modern design is not only beautiful but incredibly intuitive. Everything is laid out logically, and managing my large catalog of books in multiple formats across several retailers couldn’t be easier. The reporting options are endless, offering valuable insights across every sales platform, and the integration with Shopify is a huge bonus. Performance-wise, it’s lightning-fast—no lag like I’ve experienced with other tools. But what truly sets Publisher Champ apart is their customer service: top-notch, responsive, and genuinely open to feedback. They listen, they implement, and they continuously roll out smart upgrades that make the platform even better. If I could give more than five stars, I would. Publisher Champ is an absolute must-have for authors serious about understanding and growing their sales.
Game changer for serious authors who currently have to manually track revenue vs ad expenses and attribution ad performance. I like that data is pulled from FB ads, AMS ads, KDP platform, Kobo platform, etc automatically and that i can see how much I make on a SERIES when accounting for the ad spend on book 1. Game changer.
