Invoicing instructions

We prefer to receive e-invoices. If you cannot send e-invoices, please send your invoices in PDF format by email.

We no longer accept invoices on paper (Act on electronic invoicing of procuring entities and businesses, 241/2019, section 4).

Note that the file must be A4-sized, and any attachments should be in the same file as the invoice. You can send several invoices in one email, but each invoice must be attached as a separate file, and each file must have a different name. Each invoice file must include all of the pages relevant to the invoice.

Please note that the reference field on the invoice should state the purchase order number or at least the project number and the name of the person who placed the order.

Please do not send anything other than invoices to the invoicing addresses stated above. If you have any questions or queries about purchase invoices, please contact our Accounts Payable team.
