Online Accountant vs Traditional Firm in Brazil

In Brazil, an online accountant and a traditional firm do the same legally required job — opening the company and running its taxes — but at very different cost and speed. An online accountant opens a CNPJ for about R$ 0 to R$ 500 in roughly 5 to 10 days and charges a monthly fee that commonly starts under R$ 200; a traditional firm typically charges from R$ 500 to open, can take up to 30 days and often runs from R$ 500 a month upward. Which one fits depends less on price than on how complex the business is.

Online accountant vs traditional firm: the short answer

For service providers, self-employed professionals, companies taxed as PJ and small or digital businesses, an online accountant usually fits: the whole process is remote and lower in cost. A traditional firm tends to fit better when the operation is complex — heavy payroll, intricate tax situations or a need for bespoke, in-person advice. Both meet the same legal duty, so the decision is about the profile of the business, not about which one is “real” accounting.

What each model is

An online accountant is an accounting service delivered through digital platforms, with dedicated accountants who hold an active CRC registration and work remotely; in Brazil the established names include Contabilizei — the largest by client count — along with Agilize, Conube and Contabilix. A traditional firm serves clients in person, usually from a local office. Since 2026 the terms “online” and “digital” accounting are used as synonyms in Brazil; both still require a registered accountant, because the law does.

Cost and speed compared

The clearest differences are in what it costs to open and to run the company, and in how long the opening takes:

With the online model the opening is frequently absorbed into the monthly plan, and in certain cities some services also cover the Junta Comercial fees and the digital certificate — a saving that can reach R$ 1,800 at the start.

Who each one fits

An online accountant fits profiles that can be run digitally: service providers, self-employed professionals, companies operating as PJ, micro and small businesses and digital businesses. A traditional firm fits operations with high tax complexity, a large payroll, or owners who prefer face-to-face meetings and tailored analysis.

What stays the same

Whichever model is chosen, the law is identical: except for the MEI, every company must have an accountant with an active CRC registration, who defines the CNAE, chooses the tax regime in the MAT before the CNPJ is issued, and signs the incorporation act. Whether that duty is legally required for your company does not depend on the model, and the markers of a good online accounting service are the same either way.

Frequently asked questions

Is an online accountant cheaper than a traditional firm in Brazil? Usually yes: opening costs about R$ 0 to R$ 500 against R$ 500 or more, and monthly fees commonly start under R$ 200 against R$ 500 upward.

Is an online accountant legal in Brazil? Yes. An online accountant must hold an active CRC registration, exactly like a traditional firm; the law requires a qualified accountant, not a particular way of hiring one.

Which is faster to open a company? The online model, typically about 5 days in São Paulo and 10 in other capitals, against up to 30 days for a traditional firm.

When is a traditional firm the better choice? For complex operations, large payrolls or businesses that need bespoke, in-person advice.

Does either model change the taxes I pay? No. The taxes follow the CNAE and the tax regime, not the accounting model; both define the same regimes in the MAT.
