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.; Fyle billed per active user, defined as anyone who creates an expense or has a connected card with transactions in the month, so headcount does not predict the bill
- They diverge on capability: Causal covers Variable-based modelling, Fyle covers Real-time card tracking.
- 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.
Fyle
- Billed per active user, defined as anyone who creates an expense or has a connected card with transactions in the month, so headcount does not predict the bill
- The Growth plan carries a 5 user minimum and the Business plan a 10 user minimum, so the entry cost is set by the floor rather than the team
- API access and the Sage Intacct and NetSuite integrations require a paid tier
- ACH reimbursements and project expense tracking sit above the entry plan
- Both published plans are billed annually
- Enterprise pricing is custom and aimed at organisations with 250 or more employees

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.
Fyle: How does Fyle define and charge for active users?
An 'active user' is defined as an employee who creates at least one expense or has a credit card connected with active transactions monthly. You only pay for active users, not all onboarded employees.
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.
Fyle: What is Fyle's Growth plan pricing?
The Growth plan costs $11.99 per active user per month (billed annually) with a minimum of 5 users. Includes unlimited expense tracking, receipt scanning, and single-stage approvals.
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.
Fyle: What features does Fyle's Business plan add?
The Business plan costs $14.99 per active user per month (minimum 10 users, annual billing) and adds multi-stage approvals, project tracking, ACH reimbursements (US only), and premium support.
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.
