I'm so glad you posted this comment. I just self published my first book three days ago and the first two days, I witnessed a few sales from friends I told about my book. Then today, I had no sales reported at all in my report. My dad called me and asked how my book was selling and I told him in a sad and frustrated voice that I hadn't made any sales at all today. He called me back a couple of hours later stating that five of his coworkers purchased my book. That was about six hours ago. When I checked my reports section, it stated I still had not made any sales. I hope they fix this problem. As a new member of amazon I'm a little upset. How often does this sort of thing happen and how long does it usually take to repair?
I've noticed that every time you make any sort of change to your book, even if it's something minor like changing the category, Author Central will give you a message that your sales reporting is delayed. It's the change you performed that's causing the problem. Amazon seems to take your book 'out of the loop' for about 24 hours.
Muppetbrain and Cindy, this issue comes up every so often and I can understand your frustration. It's usually handled within no more than a couple of days and everything goes back to normal. And it's usually around the first of the month. For fairly accurate and updated info, go to novelrank.com. It's a good tool for double-checking kdp reports. Your sales always get posted, however. Don't get too distracted by the phenomenon. It will likely continue into the future. Right now sales are up, so the hidden factor here is one of increased traffic for KDP.
Thank you for the tip texaswier, and ruthlesspen it's good to know that changes to my books will affect reporting. Guess I should be focusing on new material rather than checking sales too much, but it's so tempting to see if another has slipped into the box!
I've noticed this issue going back to last month on OK sales. Nothing shows up and then in one 2 hour period 8 books sold. This month thus far 0 books in UK. I find that hard to buy given the US sales thus far.
Don't bother with novelrank.com unless you sell less than about 20 copies a month. Above that, it's so inaccurate as to be laughable. I've NEVER seen it accurately follow the Amazon sales and usually underestimates sales to an alarming extent - i.e. HUNDREDS less. I've sent them the 'real' figures occasionally, as they suggest, but it made no difference to the figure reported there. Checking sales at novelrank.com is a bit like trying to measure the amount of rain that's falling by sticking your hand out of the door and seeing how wet it gets.
