Reporting Requirements

All B2B invoices—regardless of format—must be submitted immediately to NAV’s Real-Time Invoice Reporting (RTIR) system in XML. Businesses can use qualified electronic signatures, robust internal controls or an unbroken audit trail to guarantee invoice authenticity, integrity and origin.

Standards & Platforms

NAV’s KOBAK infrastructure (also known as NAV Online 3.0) accepts invoice data in a prescribed XML schema. Whether you generate your invoices in-house or via an AP automation provider, the file you send must conform to NAV’s XML format and be delivered through the secure KOBAK endpoint.

Archiving Requirements

For VAT purposes, all invoices and their copies must be retained for five years from January 1 after the issuance date. For general accounting, retention extends to eight years. The “legal invoice” is simply the version sent or received in its original, unaltered format.
