To request an invoice for any product or service you purchased, please contact our Customer Support team via the Contact Us form or email.
Please note:
- Invoices for any given month are issued in the first half of the following month, typically before the 10th. For example, if you buy a question package on 21 March and then request an invoice, you will receive it by 10 April. In urgent cases, we can expedite your request, too.
- The prices on the website for individuals already include VAT.
- If you have an EU tax number and you provide it at the time of purchase together with the proper billing information, the VAT rate is 0%. We recommend that you verify your EU VAT number on this website https://ec.europa.eu/taxation_customs/vies/#/vat-validation.
