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.
Stampli
- No transparent pricing published; quote-based model required
- Specific pricing for individual modules or add-ons not available on pricing page
- Cost varies based on invoice volume, complexity, and customization needs

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.
Stampli: What does Stampli cost?
Stampli does not publish fixed pricing. The company uses a custom quote-based model. Visitors are directed to 'Request a Quote' and meet with an AP expert to discuss pricing based on their specific invoice volume and requirements.
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.
Stampli: What is included in Stampli's standard offering?
Stampli's core accounts payable solution includes unlimited invoice capture, entities/locations, vendors, and PO matching; automated processing via Stampli Cognitive AI; 12 pre-built reports; interactive dashboards; a dedicated Customer Success Manager; and support with under 90-second response time.
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.
Stampli: How long does it take to implement Stampli?
Stampli uses a 'fulfillment-first' implementation approach and deploys in weeks versus competitors requiring months or longer.
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.
Stampli: What add-on modules are available with Stampli?
Optional modules include Procurement, Direct Pay functionality, credit card programs, advanced vendor management, and expense management. Pricing for add-ons requires requesting a custom quote.
