The short version

  • Each has a real cost: Carta pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.; 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: Carta covers Cap table of record, Conta Azul covers Electronic invoice issuance.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Carta

  • Pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.
  • The cap table is a legal record assembled from years of board consents, so migrating to another provider means re-entering historical transactions and having counsel confirm the rebuilt table matches the signed documents, which is why most companies stay whatever they think of the service.
  • The product is built around United States company law and tax practice, Delaware entities, 409A and ASC 718, so a company incorporated in the United Kingdom, Europe or elsewhere gets a record keeping tool while the valuation and compliance features that carry the price are of limited or no use.
  • 409A valuations are delivered on a cadence and require a refresh after each material event or every twelve months, so a company that raises or changes materially is repeatedly back in a valuation process with fees and turnaround time attached, and a late valuation blocks option issuance.
  • Carta drew sustained criticism in 2024 over how customer cap table data intersected with its secondary trading business, and although it exited that activity the episode is a live reason to check what a vendor holding your ownership record is permitted to do with it.

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

Carta: Do I need Carta before I have employees with options?

No. Before options exist a spreadsheet reviewed by your lawyer is usually enough. The pressure to move normally comes at a priced round, or the first time you need a 409A to set a strike price.

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.

Carta: Is the 409A included in the subscription?

The subscription tiers bundle valuations differently and refreshes after material events can carry additional cost. Check what triggers a chargeable revaluation before you sign, because raising a round is exactly the moment you will need one.

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.

Carta: Can my accountant get the stock compensation numbers out of it?

Yes, it produces ASC 718 expense schedules and exports. If your accounts are prepared under a different framework, expect the schedules to be a starting point that your accountant reworks rather than something they post directly.

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.

Carta: Is it useful for a company outside the United States?

It can hold the share register and grants, and it does support some non United States structures. The 409A and United States tax workflow will not apply to you, so weigh it against local alternatives that understand your filings.

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.

Carta: How hard is it to leave?

Harder than the export button suggests. You can export the data, but the receiving system has to reproduce every historical grant, cancellation and transfer, and someone has to verify the result against the original signed consents.

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.

Carta: Who normally pays for it, the company or the investors?

The company, even though investors and counsel are frequent users. That is the usual complaint about the pricing model: the party paying is not the only party benefiting.

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.
