I've been selling apps in Google Play for 3 years. I found out that the sales amount in Google Wallet doesn't match with the amount that I received. The amount shown in "Business insights" for "All time" is 30% more than what I received. I wondered why I received 30% less so I reported that to the Google. Google checkout team said they need to investigate but they secretly changed my record without notifying me. I kept emailing to them about the issue but they kept changing the representative and they finally advised that the issue happened because some orders are double counted. When I ask them for the double count detail for a specific month to see how the double count occurred, they refused to give the detail to me.
If you are also a developer who sells app in Google Play, I advise you check the sales amount in "Business insights" to see if you have the same issue as me.
If the answer is yes, I advise you to do the following.
- Go to Google Wallet, click the "Business insights", check the sales amount for all time, capture a screen shot.
- In the "Business insights", export the revenue for "All time".
- Go to "Payouts", go to "Reports" tab and download the monthly record by pressing the down arrow icon.
You need to save these documents in a save place and it is better that you saved multiple copies in the USB thumb drives.
Then you can start emailing to Google about the issue. I hope the above procedures will help you to preserve some evidence before Google made the change on your record without notifying you.
If you are unfortunate as me, please email to me and we can unite together to find out the answer.
