AIT Payment Gateway

Production

Fintech · Domestic Payment Rails

QRIS & Virtual Account payment rails powering AIT products.

01 / Context

Every product that takes payment needs domestic channel integration (QRIS, bank VAs) plus reconciliation. Instead of re-integrating per product, we built one internal gateway.

02 / What we built

  • Espay integration for QRIS and multi-bank Virtual Accounts
  • One payment API reused across products (game top-up, ERP invoicing, and more)
  • Billing, callback handling, and transaction reconciliation

03 / Architecture

Product Payment API Espay (QRIS / VA) Callback Reconciliation
