Where each one falls short

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

Billin

  • Plan Basico caps usage at just 5 clients, 1 user and 10 products for EUR 6.60/month, well below what most active small businesses need
  • Plan Pro still caps clients at 50 and users at 3 for EUR 14/month, so any business with more clients must move to the unlimited EUR 23/month tier

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
