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.; Rydoo a five-user minimum means very small teams pay for seats they do not have, which removes Rydoo from consideration for firms of two or three.
- They diverge on capability: Causal covers Variable-based modelling, Rydoo covers Receipt OCR.
- 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.
Rydoo
- A five-user minimum means very small teams pay for seats they do not have, which removes Rydoo from consideration for firms of two or three.
- Pricing is per user rather than per active user, so organisations where most staff claim expenses twice a year still pay a full seat every month for them.
- There is no card issuing, so real-time spend control and pre-authorisation are outside the product and remain with your bank.
- Per diem and multi-entity handling sit on the higher tier, so the countries that most need Rydoo generally cannot buy the cheap plan.
- Receipt extraction quality varies by language and receipt format, and finance teams still review a meaningful share of claims by hand.

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.
Rydoo: Does Rydoo issue cards?
No. It is expense software only; you keep your existing corporate card or bank programme.
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.
Rydoo: Is there a minimum?
Yes, pricing carries a five-user minimum, so the smallest bill is five seats regardless of headcount.
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.
Rydoo: Do I need the Pro plan?
If you operate per diems, multiple legal entities or multi-currency claims, yes. Essentials is for single-entity receipt and approval workflows.
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.
