Yes. It is possible to issue pre-invoice and official invoice.
To receive a pre-invoice, you first need to create a user area. After registering to receive a pre-invoice, enter the order registration stage through the user area and choose the services you want. As you progress through the order registration process, you will be able to receive a pre-invoice.
Also, in order to receive an invoice, you can enter My Bills after completing the purchase by entering the financial section in the user area and download the stamped invoice. If you need to receive a physical copy of the invoice, please contact the finance department through the ticket.
