A1 or A3 — which should I choose?

For most companies, A1. It is a file, it does not depend on a token being plugged in, and it can be used by more than one system at once — including your accountants. A3 lasts longer but ties usage to the physical device.

Do I have to go somewhere to get one?

No. Validation is done by scheduled video call, presenting the original document to the camera.

I lost the certificate password. What now?

There is no recovery: the password is the key to the file, and without it the certificate will not open. The route is to issue another, with a new cost and a new validation. Which is why we insist on keeping it in a password manager rather than on paper in a drawer.

What happens if it expires?

Invoicing, filing transmission and portal access stop the next day. Since A1 lasts a year, renewal goes into the calendar well in advance — and we warn you beforehand, because the stoppage tends to happen on the worst possible day.

Does one certificate cover several companies?

No. The e-CNPJ is tied to a specific CNPJ. Anyone with more than one company needs a certificate for each.

How long does it take to open my company?

It depends on the Board of Trade in your state, but the average is 3 to 10 business days from the moment we receive your documents. We follow every stage and tell you whenever the status changes.

Do I need to come to the office?

No. The whole process is digital, from signing the contract to sending documents. If you would rather meet in person, we also receive clients by appointment.

How does switching from my current accountant work?

You do not have to speak to them. We formally request your accounting records, check what is outstanding and handle the transition. Your invoicing never stops.

Do you serve companies in any state?

Yes. We work online with clients across Brazil. State and municipal obligations are handled according to the law of each location.

What is included in the monthly fee?

Accounting and tax bookkeeping, tax calculation, ancillary filings, payroll within the plan limit and support from the accountant in charge. One-off work such as amending the articles of association or issuing certificates is quoted separately and always approved by you first.

Is there a lock-in period or cancellation fee?

There is no lock-in. The contract can be ended with 30 days' notice and we hand back your full accounting records, organised.

Need something that is not on the list? We quote it separately and only proceed after your written approval — no surprises on the invoice.

The digital certificate is the company's identity in the electronic environment. It is what signs documents, opens the government portals, transmits filings and issues invoices. Without it, much of the routine simply cannot start.

There are two formats. **A1** is a file, installed on a computer or server, valid for one year, and usable by more than one system at the same time — including the accounting firm, which saves passing a token back and forth. **A3** lives on a physical card or token and lasts longer, but depends on the device being plugged in.

We work with **A1**, issued with validation by video call: you do not have to go anywhere.

1. Choosing the type
e-CNPJ for the company, e-CPF for the individual. Business owners generally need the e-CNPJ; some filings and signatures also require the e-CPF of the responsible person.
2. Booking the validation
Issuance requires validation in person or by video call, presenting original documents. The video call resolves it without travel, and it is the route we use.
3. Issuing and installing
Once validation is approved, the file is generated and installed where it will be used. This is the moment to store the password somewhere safe: without it the file is useless, and there is no recovery — reissuing costs again.
4. Use and renewal
It then covers invoicing, eSocial, the Receita portals, e-CAC and document signing. A1 lasts one year, and renewal has to happen before expiry — an expired certificate stops invoicing the very next day.
