What it is
Pix is an instant bank-transfer payment method, not a wallet and not a company. It is a real-time payment rail operated and owned by the Banco Central do Brasil (the Central Bank of Brazil). When a customer pays with Pix, money moves directly between bank accounts and lands in the merchant's account in a few seconds, 24 hours a day, every day of the year, including weekends and holidays. Pix is built on the central bank's settlement infrastructure, so it is a public utility rather than a commercial product you buy from one vendor. Customers authenticate inside their own bank or wallet app by scanning a Pix QR code or pasting a Pix copy-and-paste string, or by using a Pix key (such as a phone number, email, CPF/CNPJ or a random key) linked to their account. For a merchant, Pix is a payment method you connect to, usually through a licensed acquirer, a payment service provider (PSP), or a local aggregator. It is the single most important checkout option in Brazil today and covers the large majority of adults who hold a bank account. Because it is a bank rail, the transaction is irrevocable once confirmed: there is no card-style chargeback, which lowers dispute risk but means refunds must be handled as a new outbound transfer. Pix also supports recurring debits (Pix Automático) and a collections format called Pix Cobrança for invoices and QR-based billing.
How customers pay
Pix matters only in Brazil. It is a domestic rail settled in Brazilian reais (BRL). Any consumer or business with a Brazilian account can send and receive Pix. It is used everywhere in the country, from physical stores and restaurants to e-commerce, billers, governments and person-to-person transfers. For a cross-border merchant selling into Brazil, Pix is effectively mandatory if you want competitive conversion and lower acceptance cost next to international cards. It does not work for customers outside Brazil, and it does not settle in any currency other than BRL through the local rail.
How merchants connect
- Through a PSP / aggregator that supports Brazil (for example dLocal, EBANX, Adyen, Stripe) — the common route for foreign merchants.
- Through a Brazilian licensed acquirer or a local sponsor bank with a direct Pix connection (best for merchants with a local entity).
- Through a payment gateway or checkout that renders a dynamic Pix QR code or a copy-and-paste string via API.
- Through a marketplace or platform that already bundles Pix as a payment method on your behalf.
Best-fit business models
Pix suits almost any merchant selling to Brazilian buyers: local e-commerce stores and independent websites, digital goods and SaaS, gaming top-ups, subscription services, B2B invoicing, and marketplaces. It is a strong fit if you want to cut card fees, avoid chargebacks, and give buyers a familiar, instant option at checkout. It is less of a fit when you need built-in installment lending (Brazilians expect parcelamento on cards) or when you cannot obtain a local settlement entity and must rely entirely on a cross-border PSP. Small merchants benefit most because Pix removes the need to negotiate card interchange and works through simple dynamic QR codes.
Cross-border and local-entity limits
Foreign merchants cannot connect directly to the Pix rail; you must go through a licensed local acquirer, sponsor bank, or an international PSP that has Pix enablement. Settlement is in BRL, so you take FX risk and cost when you repatriate. Pix transfers are irrevocable, so your refund and dispute playbook must treat refunds as separate outbound payments, and you should watch for cloned or fake Pix QR codes at the point of sale. Brazilian authorities levy an IOF tax on foreign-exchange transactions involving Brazilian consumers paying international businesses, which can affect the landed cost. Public pricing is only a first filter. Actual pricing changes with country, industry, volume, settlement currency, integration method and contract terms. Confirm against the provider's official pricing page or a written quote before you go live.
Alternatives and complements
- Boleto — voucher/cash method for buyers without a card or who prefer deferred payment.
- Credit and debit card acquiring — needed for installments (parcelamento) and high-ticket checkout.
- Mercado Pago — a wallet and PSP that bundles Pix, local cards, boleto and installments inside the Mercado Libre ecosystem.
Provider questions to ask
- Do you support Pix as a live payment method in my target countries, and what settlement currency do you pay out (BRL or my home currency)?
- What are your all-in fees per Pix transaction, including any FX, payout, and reconciliation fees — and can I get that in writing?
- How do you handle refunds, since Pix is irrevocable, and what is your dispute process for fraud claims?
- Do you support Pix Cobrança and Pix Automático for recurring billing, or only one-time QR payments?
- What are your exact payout timing and any holding or reserve policy on Pix funds?
Questions merchants ask
Is Pix enough as a standalone checkout option?
Usually no. Use Pix where it matches local buyer habits, then add complementary methods for cards, wallets, bank transfers, cash vouchers, or BNPL depending on the market and ticket size.
Can a foreign merchant connect to Pix directly?
Sometimes, but many merchants use a PSP, acquirer, aggregator, or local partner. Confirm entity, bank-account, currency, tax, industry, refund, and settlement requirements before implementation.
What should I verify before signing for Pix?
Ask whether the method is live for your entity and industry, which checkout flows are supported, how refunds and failed payments work, what fees apply, and which currency you receive.
