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.; Invoice2go starter plan caps invoices at just 30 per year, forcing an upgrade for most active businesses.
- They diverge on capability: Causal covers Variable-based modelling, Invoice2go covers Invoice creation and customization.
- 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.
Invoice2go
- Starter plan caps invoices at just 30 per year, forcing an upgrade for most active businesses.
- Card processing fees are higher than some dedicated payment processors.
- Accounting integrations are limited to QuickBooks and Xero, excluding other platforms.
- Premium plan requires roughly $100k+/year revenue to be cost-effective, per its own positioning.

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.
Invoice2go: What does Invoice2go cost?
Invoice2go offers three tiers - Starter (30 invoices/year), Professional (100 invoices/year), and Premium (unlimited invoices) - distinguished by invoice volume and card processing fees from 3.5% down to 2.9%.
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.
Invoice2go: Is there a free trial?
Yes, Invoice2go offers a 30-day free trial that requires a credit card but includes a 100% money-back guarantee if canceled within 30 days.
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.
Invoice2go: Does Invoice2go integrate with accounting software?
Yes, the Professional and Premium plans include integration with QuickBooks and Xero.
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.
