Invoices without purchase order numbers or reference numbers
If a purchase has been made through another channel than the NFI Purchasing Department and the invoice cannot be linked to a purchase order number or compulsory purchasing policy reference number, the invoice will be returned. You will be notified of this.
The notice will state that the invoice must be resent with a purchase order number and a new invoice date. You can request the order number from the commissioning party at the NFI.
