Auto-summarized by WETEC AIBIWASE Binh Phuoc implemented invoice-specific dynamic QR codes linked to its existing enterprise resource planning (ERP) system to provide an official payment channel and reduce reliance on third-party collection services. Customers can view bills and scan the matching code with a banking app; once payment is confirmed, the invoice is reconciled and its outstanding balance is cleared automatically in real time. The Android and iOS customer app also provides bill access, notifications and direct support, helping address limited app adoption and impersonated payment channels. BIWASE Binh Phuoc saves at least VND 1,000 per transaction compared with third-party collection, and all QR payments are automatically reconciled into the ERP.

Connecting customer payments to outstanding balances
Water bill collection involves the customer, the bank and the utility's commercial team. Third-party collection brings transaction fees and reconciliation work. At BIWASE Binh Phuoc, adoption of the customer app was limited, while impersonated payment channels created a need for an official channel. WETEC implemented invoice-specific dynamic QR codes connected to the existing enterprise resource planning system, or ERP.

High collection-service costs, dependence on 3rd-party channels.
Limited online presence, creating openings for scams.
