Payment Gateway & PSP Integration Services in São Paulo

Every failed transaction is lost revenue and a trust hit. Hurain Technologies designs and builds payment integration layers — from single PSP connections to full payment orchestration hubs — for fintechs, digital platforms, and marketplaces that need reliable, reconcilable, multi-currency and multi-rail payment flows, including crypto on/off-ramps. In São Paulo, that means building to the technical expectations of the local market.

São Paulo Market Landscape

Why payment gateway integration is critical in São Paulo

  • São Paulo hosts the B3 stock exchange and the largest concentration of fintech unicorns and scale-ups in Latin America.
  • Brazil's Pix instant-payment system has driven exceptional real-time transaction volume, raising the bar for fraud detection and settlement infrastructure.
  • São Paulo-based crypto businesses now operate under Brazil's 2023 crypto-asset law, giving the BCB direct oversight of virtual asset service providers.

The Challenge

Problems we see teams struggling with

High transaction failure and decline rates

Poor PSP routing and retry logic silently loses revenue on every failed or declined transaction.

Manual reconciliation overhead

Finance teams spend days manually matching PSP settlement reports against internal ledgers.

Limited payment method coverage

Missing local payment methods and currencies caps conversion in new markets.

No unified view across multiple PSPs

Operating multiple PSPs without a central orchestration layer makes routing, reporting, and risk management inconsistent.

FX cost leakage on cross-border transactions

Without FX-aware routing, businesses absorb worse conversion rates and hidden markup on every cross-border transaction than necessary.

Checkout abandonment from unsupported local methods

Requiring a card when local users expect a wallet, bank transfer, or QR payment method caps conversion before checkout even begins.
