The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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
