The short version
- Only Spendbase 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.; Spendbase charging a share of savings gives the vendor an interest in defining savings generously, and the customer cannot verify a counterfactual price it never saw.
- They diverge on capability: Causal covers Variable-based modelling, Spendbase covers Subscription visibility.
- 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.
Spendbase
- Charging a share of savings gives the vendor an interest in defining savings generously, and the customer cannot verify a counterfactual price it never saw.
- The savings share is reported at around 25 percent but is not published on the pricing page, so the actual commercial terms only appear in a contract.
- Spendbase is both a banking provider and your software negotiator, so a company using both concentrates operating cash and vendor relationships in one small, young company.
- Banking is delivered through partners rather than held directly, meaning deposit protection and service continuity depend on those partners rather than on Spendbase.
- It is scoped for startups and small companies, so organisations needing approval workflows, purchase orders or ERP integration will find it thin against a real procurement platform.

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.
Spendbase: Is Spendbase free?
The card and banking tier is genuinely free with no per-user fee. The spend management service is paid from a share of the savings it finds, reported at around 25 percent.
Causal: 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.
Spendbase: How is a saving calculated?
The methodology is not published. Agree the baseline, the measurement period and what counts as a saving in writing before signing.
Causal: 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.
Spendbase: Does Spendbase hold my money?
Banking is provided through regulated partners including Moorwand in the UK and EEA and Sutton Bank in the US, with Mastercard issuing the cards.
Causal: 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.
Spendbase: Is it suitable for an enterprise?
No. There are no purchase orders, approval hierarchies or ERP integration; it is built for startups.
