Bangkok · Payment gateway audits

We examine how money moves through your payment gateway application — settlement timing, fee ledgers, reconciliation breaks, and control gaps — then deliver a written financial audit your finance and compliance teams can act on.

Gateway Financial Audit

End-to-end financial audit of a payment gateway application covering capture, settlement, fees, reserves, and reporting relied on by finance.

Settlement Reconciliation Review

A focused examination of whether settlement files, bank receipts, and the merchant ledger close cleanly for a defined sample window.

Fee & Ledger Assessment

Trace MDR, interchange, FX markups, and reserve holds from gateway fee reports into the accounts that finance actually books.

What clients ask us to verify

  • Whether settlement files match the merchant ledger for a sample period
  • How MDR, interchange, and FX markups appear in the gateway’s fee reports
  • Whether refund and chargeback paths reverse correctly in the books
  • Gaps between application controls and finance sign-off procedures

From a recent Bangkok engagement

“They walked our settlement file line by line against our ERP. The fee mapping table alone explained a three-month variance we had been chasing.”
