You can pay for a transaction with credit card or via bank transfer (you'll find the bank details on the invoice). Please choose the option you would like to use in Offers - My Permissions Offers by clicking on the tab Awaiting Payment and then on the red "View" button of the relevant license number. In the new window select the desired payment method on the right. Clicking on Pay By Card will open a new window for submitting your credit card details securely. Selecting Pay By Transfer will download the invoice for you.
How do I view my pending permissions request?
