Hey @emmajeans, this is a great question.

So you can view a copy of the receipt on your Square Dashboard. Just head to the Sales tab and then select transactions from the top your your screen. 

You should see a list of all the payments you've processed and if you click on one it will create a pop out on your screen and you'll see all the details of the transaction!

Let me know if you're having trouble finding this section of the dashboard! 🙂
