Fortnox

  • The Fortnox Access verification tier is priced by transaction volume, rising from 9 kr/man at zero verifications to 199 kr/man at 1000+ verifications (SEK), so cost is not fixed and scales with usage

  • The Starter plan at $39 per month allows only 3 data import integrations
  • AutoFile state filings are metered: Starter includes 2 credits a year and each extra filing costs $50, Professional includes 4 and each extra costs $55
  • Real time tax calculation API access requires the Professional plan at $99 per month
  • Phone support, a Customer Success Manager and a dedicated onboarding specialist require the Professional plan
  • The developer sandbox requires the Professional plan
  • The 10% saving requires annual billing
