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

Brex

  • The free Essentials tier is limited to two legal entities
  • Premium is $12 per user per month, so cost scales with headcount using the card
  • Enterprise and Smart Card pricing is not published
  • Eligibility criteria are not stated anywhere on the pricing page, which matters for a product that extends credit
