You can update the payment method at any time in their account settings. If you own more than one Ryte account you can choose in "Accounts" which account you wish to update.
Navigate to Accounts > Payment and update your payment method. If you forgot to add your VAT ID during the sign-up process you can enter it here as well. In this view, you can also change the invoice recipient if needed.
Only the account owner can update the payment method. If you are not the account owner and need to change the payment details, please contact the person who invited you to the Ryte account – that's the owner of the Ryte account.
