Purchase receipts for transactions are emailed to you by Google soon after the purchase. However, purchases might be bundled together if you have made multiple purchases and receiving the receipt might take a bit longer.
- How to check your purchase history:
- Enter http://pay.google.com then log in with your desired Google account
- Select Actions to display your Play Store order history
- Choose an individual entry to view its corresponding receipt
All purchases are processed by Google through Google Play for Android devices. If there are any issues with the billing or have any questions about the billing process, you can contact Google here: https://support.google.com/googleplay
