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.
Pennylane
- No pricing is displayed on the homepage or linked pricing page; visitors are directed only to a Demarrer maintenant (Start now) signup flow with no published EUR figure
- The product bundles accounting, invoicing and a business bank account together, so buyers cannot subscribe to only one function

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.
Pennylane: What financial processes does Pennylane help automate?
Pennylane streamlines multiple financial functions including invoice creation, expense management, payment collection, and receipt documentation. The platform centralizes data from facturation, purchasing, treasury, and accounting in one unified system.
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.
Pennylane: Can Pennylane help with corporate spending control?
Yes. Pennylane provides corporate cards for employees with built-in spending controls and authorization workflows, allowing businesses to manage team expenses while maintaining visibility and approval requirements.
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.
Pennylane: Does Pennylane provide real-time financial visibility?
Yes. Pennylane's unified dashboard provides live transaction visibility and real-time cash flow monitoring across the entire business, helping teams access financial data instantly.
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.
