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.; Fiken bank integration available only as add-on (69 NOK/month)
- 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.
Fiken
- Bank integration available only as add-on (69 NOK/month)
- Project accounting requires separate add-on (69 NOK/month)
- Payroll and employee features cost extra (69 NOK/month)
- Physical mail invoicing costs 25 NOK per invoice

Questions people ask
- Is Causal or Fiken better?
- Neither clearly leads. Causal starts at On request and Fiken at 219/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Causal or Fiken?
- Causal starts at On request and Fiken at 219/month.
- Does Causal or Fiken run on more platforms?
- Both run on Web, so platform support will not decide this one for you.
- What is Causal best used for?
- Causal is most often used for a finance team whose three-statement excel model has become too fragile to change safely before every board meeting, a company that needs to show a range of outcomes rather than a single forecast, with uncertainty modelled directly in the drivers, a budget owner outside finance who should adjust hiring or spend assumptions and see the effect without being given edit access to the master spreadsheet, a group already running lucanet for consolidation and reporting that wants planning on the same platform rather than a separate tool. Of those, a finance team whose three-statement excel model has become too fragile to change safely before every board meeting and a company that needs to show a range of outcomes rather than a single forecast, with uncertainty modelled directly in the drivers are not what Fiken is typically brought in for.

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.
Fiken: Is there a free trial for Fiken?
Yes, Fiken offers a 30-day free trial with no credit card required. After the trial, the base plan costs 219 NOK per 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.
Fiken: Do additional users cost more on Fiken?
No, Fiken includes unlimited user accounts at no extra cost on the base plan.
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.
Fiken: What add-ons are available and how much do they cost?
Monthly add-ons include bank integration, project accounting, KID number system, and API access (69-99 NOK each). Time tracking, payroll, and expense reimbursements also cost 69 NOK per month. Annual tax filing costs 1,290 NOK for sole proprietors or 1,590 NOK for limited companies.
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.
Fiken: What are the per-transaction costs?
SMS invoicing costs 3 NOK, e-invoicing via Vipps costs 5 NOK, physical mail invoicing costs 25 NOK, and credit checks cost 15 NOK per transaction.
