The short version

  • Each has a real cost: IRIS KashFlow advertised monthly prices of £1.35 (Starter) and £2.75 (Business) are a 90% promotional discount off the standard £13.50 and £27.50 rates, and the promotion is described as lasting 6 months before reverting; 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.

Where each one falls short

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

IRIS KashFlow

  • Advertised monthly prices of £1.35 (Starter) and £2.75 (Business) are a 90% promotional discount off the standard £13.50 and £27.50 rates, and the promotion is described as lasting 6 months before reverting
  • Listed prices are in GBP plus VAT, and the platform's plans are built around UK VAT filing rather than other tax regimes
  • Annual pricing is quoted at RRP £162/year (Starter) and £291.50/year (Business) before the same promotional reduction

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.
