The short version

  • Each has a real cost: Billin plan Basico caps usage at just 5 clients, 1 user and 10 products for EUR 6.60/month, well below what most active small businesses need; 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.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Billin

  • Plan Basico caps usage at just 5 clients, 1 user and 10 products for EUR 6.60/month, well below what most active small businesses need
  • Plan Pro still caps clients at 50 and users at 3 for EUR 14/month, so any business with more clients must move to the unlimited EUR 23/month tier

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.

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.

Billin: Is there a free trial for Billin?

Yes, Billin offers a 30-day free trial with all features included. No credit card is required to start.

Source
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.

Billin: How many users does each Billin plan include?

Básico includes 1 user, Pro includes 3 users, and Ilimitado includes unlimited users.

Source
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.

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.
