Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fortnox

  • Corporate packages alone span at least 7 named tiers (Mini through Stor+) priced from 209 kr/man to 919 kr/man, and add-on programs are billed separately per module (SEK)
  • 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

sevdesk

  • The free Kostenlos plan caps invoices and e-invoices at just 3 per month, forcing an upgrade to the Rechnung plan for unlimited invoicing
  • API access and cost center tracking are reserved for the top Buchhaltung Pro tier at EUR 13.95 to EUR 34.90/month depending on commitment length, not included in the mid-tier Buchhaltung plan
