Invoice and pro-forma invoice requests

Please read the information below carefully before submitting your request.

Invoice after payment

A standard invoice may only be issued once the payment has already been received and marked as paid in the ConfTool system.

Please select this option only if your payment has already been completed.

Pro-forma invoice before payment

If payment has not yet been made, a standard invoice cannot be issued at this stage.

In this case, you may request a pro-forma invoice, which can be used by your institution as the basis for arranging payment.
