Problem
A company can spend months collecting taxes incorrectly without realizing it. All it takes is a changed tax classification in the ERP, an inappropriately framed operation, or a change in legislation that no one has been able to keep up with. When the problem appears, it may have turned into fines, lost credits, or improperly paid taxes.
For accounting offices, this happens at scale. A single office can manage dozens or hundreds of companies, each with different regimes, operations, and obligations. Checking everything manually requires time, specialized professionals and constant monitoring of the legislation.
The Tax Reform amplifies this challenge. until 2033, companies and accountants will need to deal with the transition between old and new rules, while continuing to operate normally. The problem is not just finding the right legislation, but understanding when it affects what actually happens within each company.
Solution
TributoX is a B2B tax intelligence SaaS with AI for companies and accounting offices. It applies updated legislation to the context of each company to identify tax risks and opportunities, with verifiable regulatory references.
Its regulatory data infrastructure brings together a specialized base, contextual retrieval, and validation of legal references. The API itself brings this engine to ERPs, software houses, and partner platforms, in a B2B2B distribution.
The product is evolving into continuous auditing: document analysis, operational history, deterministic checks, and inconsistency detection, to automatically identify relevant situations.
Business model
TributoX operates with SaaS subscriptions, additional consumption, and tax intelligence licensing by API.
For businesses, we offer monthly plans for R$297, R$497 and R$997, according to the usage profile. Accounting offices have plans starting at R$497, including a mode of R$1.497 Stop until 30 clients, while operations with larger portfolios can receive personalized proposals. Additional users, excess consumption, and expanded functionality can also generate revenue.
Another front is B2B2B distribution. ERPs, software houses, and other platforms can integrate TributoX with their own products, with API contracts negotiated by volume of use or revenue sharing.
This model allows increasing revenue both through direct acquisition and expansion of existing accounts and through the commercial reach of partners.
Market
The global tax management market, including software and associated services, is estimated at US$ 26,3 billions in 2026, with projected annual growth of 11,3% unto 2033, according to Grand View Research.
Brazil is our initial market, with 25,4 millions of active companies and 106,6 a thousand accounting organizations. We serve companies and offices of different sizes, with tiered plans, customized contracts and API integration.
Our modular and API-first architecture allows the reuse of AI, document processing, business context and analysis mechanisms, adapting the tax layer to the rules of each country.
The strategy is to consolidate the operation in Brazil, expand to Latin America and then reach global markets, distributing our tax intelligence directly and through ERPs, software houses and B2B platforms.
Competitors
The Brazilian tax intelligence market includes companies such as Systax, DGTAX, OmniFisco and Virtio Fiscal, which work in tax compliance, auditing, parameterization and tax analysis. We also compete indirectly with specialized consultancies, tax research platforms, and generic artificial intelligence tools.
TributoX combines continuously updated legislation, the individual context of each company, and artificial intelligence to identify legally based tax risks and opportunities.
Our strategy is to deepen this capacity with continuous auditing and also make it available via API, allowing ERPs, software houses, and B2B platforms to incorporate tax intelligence into their products. The difference lies in the integration of these capabilities, not in the exclusivity of each technology.
Competitive differentiation
TributoX goes beyond a tax chatbot. Our technology combines a specialized base of continuously updated legislation with the real context of each company, allowing us to identify tax risks and opportunities with legal basis.
The system uses evidence retrieval mechanisms, verifiable regulatory references, and low confidence signaling when there is insufficient information to support a conclusion.
We also offer our own, authenticated and asynchronous API, which allows us to integrate our tax intelligence with ERPs, software houses, and other platforms.
We are evolving this infrastructure with deterministic checks, data reconciliation, and anomaly detection to enable continuous auditing.
Our differential lies in the combination of regulatory knowledge, business context, traceability, and API distribution, without depending on a single AI model.
Entry barrier
Creating a tax chatbot is relatively simple. The challenge is to build an infrastructure that continuously monitors legislation, understands the context of each company, and supports its analyses with verifiable evidence.
TributoX already has a specialized regulatory base, contextual retrieval mechanisms, validation of legal references, and its own API in production.
Our architecture is evolving to incorporate operational history, deterministic checks, data reconciliation, and anomaly detection.
The barrier to entry lies in the combination of structured tax knowledge, regulatory updating, traceability, integrations, and validation with real data. The more companies and platforms that use this infrastructure, the greater our operational learning and ability to improve the product, regardless of the AI model used.
Traction
TributoX began to be developed and validated in 2025 with partner accounting offices. Monetization began in 2026 and we achieved 147 paying customers in seven months, with R$ 322.534 of revenue received in the period. We left R$ 6 thousand in the first month for a monthly peak of R$ 74 thousand; in the most recent month, we received R$ 71.534.
We grew without external investment, mainly through direct acquisition, referrals and partnerships with accounting offices. We serve accountants, offices, and companies and we already have a functional API for integration with other platforms.
The next step is to expand distribution, structure acquisition and retention, and validate continuous auditing with real data. The amounts reported are revenues received, not MRR: we are separating subscriptions and variable components to accurately measure recurrence, churn, and expansion.
