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.; Soldo cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
- They diverge on capability: Causal covers Variable-based modelling, Soldo covers Prepaid company cards.
- 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.
Soldo
- Cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
- The plan fee covers only three users, and per-user charges plus physical card fees mean the real monthly cost is several times the advertised headline for a team of twenty.
- It does not extend credit, so it gives no working capital benefit and no card rewards of the kind US charge card issuers use to offset their cost.
- Sole traders and some business types are not accepted, which catches out small consultancies expecting to sign up online.
- Coverage is European; a company with US or Asian subsidiaries will need a second card programme and a second expense workflow for them.

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.
Soldo: Is Soldo a credit card?
No. It is prepaid electronic money. You fund a wallet and cards spend from it, so there is no credit line and no interest-free period.
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.
Soldo: What licence does Soldo hold?
Soldo is authorised as an electronic money institution, including UK, Irish and Italian entities, which is why it can issue cards without a sponsor bank in those markets.
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.
Soldo: What does it really cost for twenty users?
Take the plan fee, add the per-user rate for the seventeen users beyond the included three, then add card issuance fees per physical card.
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.
