Once identified within the control panel, to access the Check-in Scan invoices, you have to click on the My Account drop-down menu. This is in the upper right corner just below the language flag. And then click on Invoices.

The Invoices panel will open. In the left column all your invoices will appear in chronological order.

To view, print or download them you have to click on the PDF icon. You can find this on the right side next to the last column of each invoice.
