This is an incredible tool and so flexible. Not only does it allow me to see all my royalties in one place (impossible outside of Xero) but the API feeds make it so easy to set up and maintain. I had it set up in less than 5 minutes. For me, the Amazon Attribution analysis feature is the real value-add, removing hours of manual exporting and analysis for my team each week. I can make decisions on my ads at a glance and it's really helped my most recent launch. Also a big shout-out to the founder, Eiri, who has been incredibly responsive on the messenger function and is so open to feedback and suggestions. Highly recommend.
This site is AMAZING! I had no idea the details I was missing out on for my book biz. I know things now I didn't even think to ask about. I still have way more to learn as I just signed up yesterday. If you have a publishing business, you HAVE TO HAVE THIS! It's amazing!
Get this software if you want to save tons of time and improve your understanding on your books' P&L and finance across different platforms! Best software!
brilliant service - highly recommend.
Eiri is the definition of a professional and engaged developer; that approach is abundantly clear in the quality and evolution of Publisher Champ. If publishing seriously, this is a must-have tool.
Best KDP Data Tool I've ever used. So much functionality, clear information, fantastic price as well.
TOP! Kann ich sehr empfehlen für alle Selfpublisher. Guter Service, sehr zufriedenstellend.
I had been using a similar app, but found Publisher Champ more robust. Easy to navigate and the price is reasonable. Well worth it!
Publisher Champ is mandatory for all publishers!
A unique and indispensable app for self-publishing. Without it, keeping accounts manually and doing statistics would really be impossible.
