In order to request your royalties payment, you should click on the green button “Request outpayment” inside your user account ("Sales > Balance" section).
You can request your royalties as soon as your balance overcomes the 50€ threshold. If the amount does not reach 50€, the green button will not be visible.
Is necessary that you fulfill the obligations to complete correctly your profile in order for us to make the payment, as well as sending us the invoice to email@example.com.
You can find more information about the payment options in this article.
