The short version
- Only Navan 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.; Navan enterprise pricing requires quote request; no transparency on true per-user or per-transaction costs
- 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.
Navan
- Enterprise pricing requires quote request; no transparency on true per-user or per-transaction costs
- Expense management charges apply beyond 5 users, increasing per-user costs for larger teams
- Corporate card programmes (Navan Card, Connect) complicate adoption by requiring banking integration
- AI assistant (Navan Edge) lacks transparency on data handling; unclear whether conversation data is retained for model training
- Limited EMEA coverage; emerging market travel inventory less comprehensive than global GDS systems

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.
Navan: Is Navan's travel booking free?
Yes. Navan Business travel bookings are free, supported by supplier commissions. Expense management is free for the first 5 users monthly; additional users cost £15/month each.
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.
Navan: What is Navan Edge?
Navan Edge is an AI travel assistant integrated into chat that handles flight, hotel, and restaurant enquiries, provides recommendations, processes cancellations and rebookings, and escalates to human support 24/7.
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.
Navan: Does Navan integrate with our ERP system?
Yes. Navan provides 30+ pre-built ERP connectors (SAP, Oracle, NetSuite, etc.) and REST APIs for real-time spend sync and invoice reconciliation.
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.
