Ok, so I sell apps on Google Play. Google are removing Google Checkout, so I've been moved to Google Wallet as a merchant. My app money for the previous month is transferred every month on the 15th, and it came through on the 17th. However, it would appear they sent me the money twice, it came through on the 17th and the 18th. So, what should I do? I would keep the money, but I'm scared Google will chase me and demand it back :/
Contact them and let them know. It's their mistake, but better to keep on their good side and be honest. Don't worry, they won't contact your mum to ground you. :-P
Just got off the phone to them, it seems there was an issue with the system where google play developers received 2 payouts. They resolved the issue, but the developers that received the two payouts will have the second deducted from their next payments...
