On Youdot, you only have one payment call made each month on the date you entered your payment method. For instance, if you entered your payment informations on December 15th, your payment calls will be made on the 15th of each month.
Payment calls include all your purchases and registrations in a single downloadable invoice.
Click on the "Bills" tab in the "Transactions and billing" section of your account. All of your invoices should be available in PDF format.
If a blank page appears when you click the button, just wait a few seconds for your invoices to load.
If you want your upcoming invoices to have a different billing address, remember to change your details from your account before the payment call (on the last day of the month).
