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.; Conta Azul it is a Brazilian product with Brazilian fiscal logic, so it is of no use to an entity filing anywhere else, and a foreign group with a Brazilian subsidiary runs it as a local island alongside whatever the group reports in.
- They diverge on capability: Causal covers Variable-based modelling, Conta Azul covers Electronic invoice issuance.
- 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.
Conta Azul
- It is a Brazilian product with Brazilian fiscal logic, so it is of no use to an entity filing anywhere else, and a foreign group with a Brazilian subsidiary runs it as a local island alongside whatever the group reports in.
- Plans are scoped by revenue band, so a company that crosses a threshold pays more without necessarily using more of the product, and budgeting the software cost means forecasting turnover rather than usage.
- It is not a tax calculation and filing engine, so the accountant still prepares the statutory obligations, and a business that expects the subscription to cover its Brazilian tax compliance has misread what it is buying.
- Municipal service invoice coverage varies by city because each municipality runs its own system, so a business in a smaller or unusual municipality may find its service invoices still have to be issued on the city portal by hand.
- The product targets micro and small companies under the simplified regime, so a business that grows into the more complex Brazilian tax regimes will outgrow it and face a migration at exactly the moment its accounting is becoming harder.

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.
Conta Azul: Does Conta Azul do my tax filings?
No. It organises the operational and financial records and shares them with your accountant, who prepares and files the tax obligations. It is the record keeping layer, not the compliance filer.
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.
Conta Azul: Can it issue service invoices for my city?
Coverage depends on your municipality, because each runs its own service invoice system. Check your specific city before subscribing, since a gap there is the difference between automation and manual issuance.
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.
Conta Azul: Why does the price depend on my revenue?
Plans are banded by turnover rather than purely by features or users. It keeps the entry price low for very small companies, but it means growth triggers a price change independent of how much of the product you use.
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.
Conta Azul: Will my accountant work in it?
Many Brazilian practices already do, and there is a dedicated accountant role. Ask your accountant before subscribing; if they work in a different product, the friction of running two systems usually falls on you.
Conta Azul: Is it suitable if I leave the simplified tax regime?
It is built around smaller companies and the simplified regime. As the tax treatment becomes more complex, expect to outgrow it and to face a migration alongside a change of accounting complexity.
Conta Azul: Is there an English interface?
It is a Brazilian product in Portuguese, aimed at Brazilian owners and accountants. Plan for Portuguese language operation.
