The short version
- Each has a real cost: Causal causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.; 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.
- They diverge on capability: Causal covers Variable-based modelling, Circula covers German per diem engine.
- 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.
Causal
- Causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- Self-serve pricing is gone: the old causal.app pricing page now redirects to a Lucanet solution page, so what was a transparent product you could sign up for is an enterprise sales conversation with no published rate.
- The variable-based model is a genuine departure from spreadsheet thinking, so an accountant fluent in Excel must relearn how to express a model, and the team members who could previously all edit the forecast often cannot at first.
- Deep Excel compatibility is limited by design; complex existing workbooks with macros, circular references or heavy lookups do not import cleanly and have to be rebuilt, which turns a tool evaluation into a modelling project.
- Consolidation, statutory reporting and multi-entity currency handling are weaker than in dedicated corporate performance management suites, so a group with several legal entities usually needs Lucanet’s other modules alongside it, raising the real cost well past the planning tool alone.
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.

Answered from the vendors’ own pages
Causal: Does Causal still exist?
The product does, as Lucanet xP&A. The independent Causal brand and self-serve offering have been retired following the October 2024 acquisition.
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.
Causal: What does it cost now?
Nothing is published. The former pricing page redirects to Lucanet, and the product is quoted as part of the Lucanet CFO Solution Platform.
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.
Causal: Can I import my existing Excel model?
Simple workbooks import. Models with macros, circular references or heavy lookup chains have to be rebuilt around named variables, which is the real migration cost.
Circula: Is there a minimum commitment?
Yes. A minimum of ten licences and annual billing on the published rates.
Causal: Is it a replacement for a consolidation tool?
No. It plans and forecasts. Statutory consolidation and multi-entity reporting sit in Lucanet’s other modules.
