At last, a platform that does what it promises! It's a refreshing experience after much frustration with other platforms that didn't deliver.
Publisher Champ is an essential tool to have, in my opinion. Before using it I was completely blind to my daily spending vs net royalties, organic vs inorganic sales. I can't imagine publishing without it anymore!
This is by far, hands down, the only app to use if you're an online publisher through Amazon, etc. This app was recommended to me by another author, and he was right. Also, the app developer is super responsive and helpful, which is beyond unique and amazing. 5 stars is not enough!
What an incredible app! If you're a widely published author I can't recommend this highly enough! I've used other author aggregators before, but this breaks out your data so well and visually! Absolutely love it.
very responsive customer service. I am still learning how all the features work. I am a wide author so it's hard to find a software that helps me visualize my earnings across many channels.
Excellent tool that proves valuable insights in a fraction of the time. Of particular benefit is the ability to see Meta advertising effectiveness and match to sales on a granular level across retailers. Much thought went into this, and help, if needed at all--is super fast and friendly. Easy to use.
I can't emphasize enough how much I love this product and the amazing customer service. The founder Eiri is always there to answer any questions. I needed help finding the data I needed for a report and within no time, he guided me and I was able to export my report. HIGHLY RECOMMEND.
Publisher Champ has been a game changer in the couple of weeks that I've had it. Really loving this program. Makes finding just about anything that I want a few clicks away. Stats and Analytics seems to be exactly what Amazon has, which is fantastic. I get up-to-date information and it's super easy to review and access. I can't imagine how much work went into making this.
Phenominal Customer Support! Answers instantly - as if he as reading my mind. Turns out the issue was not a problem with synchronization, but the fact that I didn't understand how to read the data in the columns. The presentation of information is top notch and so much to digest. I do appreciate the many options and understanding how best to track profitability. Especially like the "cha-ching" sound for every sale recorded. Nice touch.
Excellent analytics and impeccable customer service. Couldn't recommend highly enough. The UI is easy to understand and let's me easily stay on top of how my book catalog is performing across platforms.
