1. Technology overview
Casso Company Limited was registered in Ho Chi Minh City on 7 April 2021 and operates from the Software Technology Park of Vietnam National University. It describes its product as a financial robot for businesses, automating the bank-statement and cash-flow work that Vietnamese SMEs and online sellers still do by hand.
Casso connects to a company’s bank accounts through official bank APIs, pulls transactions continuously and pushes each new credit to a customer webhook, so an e-commerce order can be confirmed without a human reading the statement. The line covers Casso Flow for bank API access and reconciliation, payOS as a VietQR-based payment gateway settling into the merchant’s own account, Casso Table for cash-flow tracking and X Invoice for e-invoicing. Casso became an official VietinBank API partner in 2021 and delivered with VietinBank the first balance-change webhook service for individual accounts in Vietnam. Supported banks include MB, OCB, VietinBank, ACB, KienlongBank, LPBank, BIDV, Shinhan Bank and PVcomBank.
