The short version
- Only sevdesk has a free tier, so it costs nothing to try first.
- 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.; sevdesk the free Kostenlos plan caps invoices and e-invoices at just 3 per month, forcing an upgrade to the Rechnung plan for unlimited invoicing
- 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.
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.
sevdesk
- The free Kostenlos plan caps invoices and e-invoices at just 3 per month, forcing an upgrade to the Rechnung plan for unlimited invoicing

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.
sevdesk: How much does sevdesk cost?
sevdesk offers a free plan and three paid tiers. Invoice Plan starts at €11.90/month (€4.45/month on 24-month), Accounting Plan at €25.90/month (€9.95/month on 24-month), and Accounting Pro at €34.90/month (€13.95/month on 24-month).
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.
sevdesk: What is included in sevdesk's free plan?
The free plan allows creation of up to 3 invoices/e-invoices monthly, unlimited contact creation, and access to support materials. No credit card is required.
