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.

Mercury

  • Treasury access requires a $250,000 balance held with Mercury
  • Non USD international wires carry a 1% conversion fee
  • Choosing OUR wire coding, which covers intermediary bank charges, costs $15 per wire
  • ACH invoicing is $1 per transaction on Mercury Plus and only free on the $299 a month Pro plan
  • Advanced and recurring invoicing require Mercury Plus at $29.90 a month
