Where each one falls short

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

Circula

  • The module pricing stacks: expenses at fifteen euro per licence plus ninety nine euro for cards plus a hundred and forty nine euro for accounts payable means a fifty person company pays well over a thousand euro a month before add ons.
  • A minimum of ten licences excludes small teams, and the flexible licensing model for occasional claimants makes monthly cost harder to forecast than a flat per seat price.
  • Strength is in German tax rules, so companies with significant operations outside the DACH region gain little from the feature that justifies the price.
  • The accounts payable module includes only a hundred invoices per month, so invoice heavy businesses face metered overage on top of the platform fee.
  • Card issuing carries a per card transaction ceiling and depends on partner issuing, so high value procurement spend can hit limits that a bank issued corporate card would not.

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
