The short version
- Only Invoicely 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.; Invoicely free plan is limited to just 5 invoices and 3 clients per month, and PayPal-only payments.
- They diverge on capability: Causal covers Variable-based modelling, Invoicely covers Invoice creation.
- 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.
Invoicely
- Free plan is limited to just 5 invoices and 3 clients per month, and PayPal-only payments.
- No native mobile app mentioned, limiting on-the-go invoicing.
- Team member limits on lower tiers can be restrictive for growing businesses.
- No listed integrations with accounting platforms like QuickBooks or Xero.

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.
Invoicely: Is there a free plan, and what are its limits?
Yes, the Free plan allows up to 5 monthly invoices and 3 saved clients, with PayPal-only payments and no team members, and requires no credit card.
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.
Invoicely: What does Invoicely cost?
Paid plans start at Basic for $9.99/month, Professional at $19.99/month, and Enterprise at $29.99/month, each raising invoice, client, and team member limits.
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.
Invoicely: Can I change or cancel my plan?
Yes, Invoicely allows customers to upgrade or downgrade their subscription level at any time.
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.
