PIX/BaaS

Key points

• PIX/BaaS is the model in which a regulated institution provides other companies with ready-to-use PIX infrastructure.
• It allows a fintech or platform to offer instant payments without itself being an institution authorized to operate on the system.
• The provider handles the transactional account, keys, and reconciliation, while the client company focuses on its own product.

What is PIX/BaaS?

PIX/BaaS combines PIX with the concept of banking as a service. It is the arrangement in which an authorized institution offers its payment infrastructure to third parties, who consume it through integrations. This way, a company that is not a regulated financial institution can still offer PIX features to its own users, relying on the provider's structure.

How it works

In the traditional model, participating in PIX requires being an authorized institution connected to the system, which involves significant regulatory and technical requirements. BaaS solves this by intermediating that access: the regulated provider maintains the connection to the payment system and exposes its capabilities through interfaces that client companies integrate into their products.

In practice, the provider offers transactional accounts, the creation and management of PIX keys, the sending and receiving of payments, and reconciliation, which matches each amount received to the corresponding charge. The client company appears to the end user as the one offering the service, while the regulated infrastructure runs underneath, under the provider's responsibility.

This model is especially relevant for platforms that need settlement in reais, including those that operate with crypto. A service that converts stablecoins into reais, for example, relies on a PIX/BaaS provider to deliver the final amount to the beneficiary's account, handling the regulated part of the operation without having to build it all from scratch.

The division of responsibilities between provider and client, including compliance obligations, is defined by contract and varies according to the arrangement.

Why it matters

Understanding PIX/BaaS helps explain how many fintechs and platforms offer instant payments without themselves being regulated institutions. For a company, it is what makes it feasible to integrate PIX into a product quickly. This is a description of infrastructure and does not represent any recommendation to operate.

Risks and limitations

In PIX/BaaS, the client company depends entirely on the provider: its failures, instabilities, or compliance issues directly affect the service offered to the end user. The division of regulatory responsibilities must be clear in the contract, and the extra layer of intermediation adds cost. None of this represents a recommendation to operate.
