The short version
- Each has a real cost: Adyen there is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic; 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.
- They diverge on capability: Adyen covers Payment processing, Causal covers Variable-based modelling.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Adyen
- There is a minimum monthly invoice, set by industry and business model and only disclosed through the sales team, so small volumes are not economic
- Published fees are indicative rather than a rate card, with real pricing negotiated
- Interchange++ means the card cost varies per transaction rather than being a single predictable percentage
- Alternative payment methods carry their own rates on top, such as 3.3 percent plus $0.10 for American Express in North America
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.

Answered from the vendors’ own pages
Adyen: How much does Adyen charge per transaction?
Adyen charges a fixed $0.13 USD per transaction plus a variable fee based on the payment method used. Credit cards typically cost $0.13 + 0.60% + interchange, while digital wallets and BNPL options cost between $0.13 + 0.99% to $0.13 + 4.99%+, depending on the specific method and region.
SourceCausal: 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.
Adyen: Does Adyen have monthly subscription or setup fees?
No, Adyen has no setup fees or monthly recurring charges. You pay only for each transaction processed. The transaction fee structure remains the same regardless of transaction volume or business size.
SourceCausal: 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.
Adyen: What's Adyen's Interchange++ pricing option?
Adyen offers an Interchange++ transparent pricing model that passes interchange and scheme fees directly to merchants instead of bundling them into a percentage rate. This allows visibility into exact costs for each payment method.
SourceCausal: 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.
Adyen: Can I process payments in multiple currencies with Adyen?
Yes, Adyen supports 100+ payment methods across multiple currencies. You can link multiple bank accounts in different currencies to avoid currency conversion fees on international transactions.
SourceCausal: 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.
