Where each one falls short

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

Karbon

Monthly billing option only available for teams of 4 or more users
Team plan at $59/month per user minimum cost may be expensive for smaller practices
No seat license discounts published; scaling costs linearly with user count

Rydoo

A five-user minimum means very small teams pay for seats they do not have, which removes Rydoo from consideration for firms of two or three.
Pricing is per user rather than per active user, so organisations where most staff claim expenses twice a year still pay a full seat every month for them.
There is no card issuing, so real-time spend control and pre-authorisation are outside the product and remain with your bank.
Per diem and multi-entity handling sit on the higher tier, so the countries that most need Rydoo generally cannot buy the cheap plan.
Receipt extraction quality varies by language and receipt format, and finance teams still review a meaningful share of claims by hand.
