As a business user of the referral program, you can request a credit note, which you will need for your tax return. To do so, please fill in the online form. The initial request is sufficient and you will receive the documents on an ongoing basis. The credit note will be issued upon request within 3 working days, taking into account the rewards confirmed by then. Credit notes will be sent to you by email.
 

Note: In order for us to issue a credit note, you must first cash out your reward. We can only issue a credit note after the payout.
