Nothing changes in the way you are invoiced.

You use your Q8 liberty card in the Q8 app solely to authorize your refueling session.
Invoicing works in the same way as when using the physical card, namely at the end of the month.

Do you pay by direct debit?
Then this will continue as usual.

You can recognize a mobile fueling transaction on your invoice by the “M” indicator next to the card number.
