When you start using Procountor Solo, we will automatically order electronic invoice addresses for you. When you log in for the first time and the Solo program is no longer in trial use, you will receive the new electronic invoice addresses within 24 hours. We send you the addresses automatically, and this does not require any action from you.
When the electronic invoice addresses have become available to you, you will see them in the program under Settings > E-invoicing. You can notify invoicing companies of your new invoicing information by e-mail, for instance. The notification specifies the address to which the invoices should be sent from now on. The E-invoicing view in Solo contains a pre-filled notification template for electronic invoice addresses.
