Invoicing PRIO

PRIO prefers to receive invoices and credit notes from within Norway on EHF format (Elektronisk HandelsFormat). Vendors and partners from abroad may submit as PDF via e-mail. Instructions and requirements for both methods follow below.

EHF invoices

The address for invoices on EHF-format is Institutt for Fredsforskning, organisation number: 847353732.

If a vendor does not have in place its own system for issuing invoices on the EHF-format, it is possible to benefit from services available at a number of web portals to send EHF-invoices.

Requirements for invoices submitted to PRIO in the EHF-format

PDF invoices

An invoice submitted as an attachment to an e-mail sent will be forwarded to the processing queue in PRIO's solution for interpretation and verification of incoming invoices. The initial processing is automated and amounts to transferring the attachment only to another system. Links and body text in the email are not read or processed.

Requirements for invoices submitted to PRIO by e-mail

  • The invoice must be in one of these formats: PDF, JPEG, JPG, PNG, TIFF or TIF.
  • Invoices on invalid file formats will not be processed.
  • Include only one attachment/invoice per e-mail.
  • Do not enter any invoice information in the e-mail itself, only in the attachment. E-mail text will not be read or processed.
  • A link to an invoice, included in the e-mail, will not be processed or forwarded to the interpreter program.
  • The invoice must provide the name of a reference person at PRIO to avoid delays in the processing of the invoice.
