Pix Automático

Pix Automático extends Brazil's dominant real-time payment rail into the recurring billing space — a segment previously served almost entirely by boleto bancário (bank slip), direct debit via SEPA-equivalent DEBITO EM CONTA, or card-on-file. For operators serving Brazilian consumers, Pix Automático is the emerging default for subscription collection.

How Pix Automático Works

Pix Automático uses a two-phase consent-and-execution model:

Consent setup: The customer authorises the merchant to debit their account, via a notification in their own bank's app or by scanning a QR code. This runs inside the Pix arrangement, directly between the payer's PSP and the receiver's PSP — not through Open Finance. The BCB's implementation guide places the payment-initiator model, which does use Open Finance specifications, explicitly outside its own scope; that model is an optional parallel channel chosen by the receiver, not the default path. The consent specifies the receiver, whether the amount is fixed or variable, a ceiling the payer sets, the frequency, and the duration.

Execution: The merchant's financial institution (or PSP) sends a Pix debit request referencing the active consent. BCB's SPI (Instant Payment System) validates the consent and executes the transfer, typically within seconds. The customer receives a debit notification via their banking app.

Disputes are handled through the bank — customers can revoke consent at any time via their bank app, and BCB's MED (Mecanismo Especial de Devolução) framework covers unauthorised charges.

Economics vs. Card Recurring

The cost difference between Pix Automático and card-on-file recurring is material for high-volume merchants:

For a subscription business with R$200/month average transaction value at 2% card MDR, Pix Automático at 0.3% MDR represents a saving of approximately R$3.40 per transaction — meaningful at scale.

Comparison to VRP and SEPA SDD

Pix Automático, VRP (UK), and SEPA Direct Debit represent three national approaches to the same problem: enabling recurring bank-account-based debits with consumer consent protections.

Operator Considerations

Market opportunity: Brazil has ~215 million people, 148 million of whom (about 86% of the adult population) made or received at least one Pix transaction in 2025, and card penetration in the unbanked and lower-income segments remains limited. Pix Automático reaches consumers that card-on-file does not.

Integration path: Merchants need a Brazilian financial institution or PSP that has implemented Pix Automático on the receiving side. Integration uses the Pix API, not the Open Finance Brasil APIs, unless the merchant has deliberately chosen the payment-initiator model. Payer-side support is mandatory for Pix participants offering transactional accounts; receiver-side support is optional, so availability depends on the collecting PSP. Operational mechanics — mandate states, retry limits, refunds and reconciliation identifiers — are covered in the Pix Automático operations reference.

Risk consideration: Unlike card payments, Pix Automático does not have a chargeback mechanism equivalent to card disputes. MED carries two distinct tracks here: the ordinary fraud track, unchanged from any Pix transaction, and a Pix Automático refund category covering authorisation mismatch or an absent authorisation, on which the payer's PSP must refund in full within 24 hours and seek reimbursement afterwards. Treating the second as if it were a card chargeback misjudges both the timing and who is out of pocket first.
