To find an overview of your invoices from IEX, log in to app.iex.dk with your username and password to IEX version 3.
In the menu, go to Subscription to find an overview of your invoices.
Here you can do the following:
Download your invoice as a PDF
Open your invoice in the browser window
Note: If your subscription is set to payment by credit card, and the payment fails due to missing payment method or a withdrawal error, there will be added an invoice fee of DKK 39. This amount will not appear on your invoice in the overview, but it will be added to the invoice, that you receive by mail.
