Fortnox Plans Pricing
Fortnox is sold as a per-user, per-month SaaS in Swedish kronor (SEK, excl. VAT). Customers pay a base "Fortnox Access" platform fee plus one or more program/package licenses (invoicing, bookkeeping, bookkeeping plus, complete), scaling by users and add-on modules. The REST API and the WebSocket Topics API are available to registered developer applications; Fortnox does not charge a separate per-request API fee for a customer's own integration - paid third-party integrations are instead distributed via the Fortnox marketplace under a revenue-share. The SEK figures below are representative snapshots from mid-2026 public sources and are NOT reconciled; Fortnox revises pricing often.
