At Youdot, you only have one payment call on the last day of the month. It includes all your purchases and registration, in a single invoice to download.
Click on the invoice button in your "transactions and invoices". A tab opens and your invoice is available in pdf format.
The tab opens and you just have a blank page? Wait a few seconds for your invoice to load.
Do you need an invoice with another billing address? Remember to change your details from your account before the payment call (on the last day of the month) so that this address is on your invoice.
