The short version

  • Each has a real cost: 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.; Solaris baFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • They diverge on capability: Circula covers German per diem engine, Solaris covers German banking licence.
  • Prices and features above were last checked on 1 September 2026.

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.

Solaris

  • BaFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • BaFin fined Solaris EUR 6.5 million in March 2024 for systematically late suspicious activity reports and EUR 500,000 for breaching large exposure limits between January 2022 and March 2024, which is a track record a partner inherits reputationally.
  • Solaris has previously needed BaFin approval before onboarding new corporate clients, which can turn a commercial decision to launch into a regulatory timetable outside your control.
  • The 2024 restructuring involved job cuts and the closure of parts of a business unit, so product lines a partner depends on may not have the engineering behind them that the sales process implies.
  • SBI Holdings acquired majority control in 2025, so strategic direction now sits with a Japanese financial group whose priorities for the European business may differ from the roadmap you were sold.

Answered from the vendors’ own pages

Circula: Does Circula calculate German per diems automatically?

Yes, by destination country and trip duration, including meal and accommodation deductions, which is the main reason DACH finance teams buy it.

Solaris: Does Solaris have a real banking licence?

Yes. Solaris SE is a German credit institution, which is why it can offer deposits and lending, unlike e-money based competitors.

Circula: What does it actually cost for fifty employees?

Roughly seven hundred and fifty euro a month for expense licences alone at the fifteen euro rate, before the ninety nine euro card platform fee and any accounts payable module.

Solaris: Is the BaFin action still live?

The special representative appointed in 2022 had the mandate extended in July 2024, and fines were issued in March 2024. Treat supervisory oversight as an active condition in your diligence.

Circula: Is there a minimum commitment?

Yes. A minimum of ten licences and annual billing on the published rates.

Solaris: Who owns Solaris now?

SBI Holdings of Japan agreed in December 2024 and January 2025 to take a majority stake of over seventy per cent for around EUR 100 million.
