Best software for publishers. Would not know how to survive without it.
Amazing and unique service in my experience. Comprehensive data and constant development. I love it!
Nobody does it better. This has become the go-to tool for anyone who is managing an author business, and I imagine actually any publisher is managing any kind of publishing business. What's more, the founder seems to be constantly available on the chat and has been so for the last couple of years as far as I remember which is quite insane. Thank you Eiri for this magical tool.
I love Publisher Champ. It helps me check on the health of my business at a glance.
I use this tool for Amazon KDP. The dashboard on Amazon is impossible to work with but on Publisher Champ I can actually see which books are selling. I like how all the numbers are laid out where I can compare todays sales to yesterdays and this months performance compared to last months. it also links to my amazon ads so i get to see my actual net profit and not just the gross. Great job guys! oh and excellent support team too
This platform saves authors so much time making business decisions. I wouldn't be without it, especially with the API feature.
Amazing product, if you are planning to publish this is a must have...
This is the tool we've all been yearning for. What a powerful asset! Worth every penny!
This tool is perfect, and the founder always responds in real time. Highly recommended for serious KDP publishers !
The best tool for publishers who want to keep track of their book's performances across all plattforms. In addition, customer support service is outstanding - response rate is extremely high and the support always helpful. They really take into account user's feedback and demand, and keep improving the features and adding more useful features over time. Gold standard! Highly appreciated and highly recommended.
