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

Vena Solutions

  • Vena publishes no pricing and contracts are modular, so two organisations of similar size can pay very different amounts and neither can benchmark without going through procurement.
  • Implementation services for data integration and template configuration typically make up a large part of first-year cost, often exceeding the licence, and that figure only appears in the proposal.
  • Excel dependency is structural: organisations on Google Workspace, or staff working only in a browser or on Chromebooks, cannot use the primary interface as intended.
  • Because it accepts existing spreadsheets, it can preserve years of undocumented logic and circular workarounds rather than forcing the clean-up that a rebuild on a purpose-built modelling tool would require.
  • Model performance degrades with very large dimensional models, so organisations that grow into genuinely large planning problems eventually hit the limits of the spreadsheet-first design and face a second migration.
