Singapore Implements Invoice Response for B2G E-Invoices

The Accountant-General’s Department (AGD) has introduced the Invoice Response document, enabling real-time status updates for B2G e-invoices sent through InvoiceNow, Singapore’s Peppol-based e-invoicing network.

Singapore has already established Peppol as the default mechanism for Business-to-Government (B2G) invoice exchange. With the addition of the Invoice Response document, public entities now support an extra document type that improves visibility and automation in the invoicing lifecycle.

The Invoice Response document is currently available for e-invoices sent to AGD’s Peppol ID. B2G suppliers that are enabled for Invoice Response can receive invoice status notifications directly through their accredited service provider, removing the need to manually track invoice progress on the Vendors@Gov portal.

In cases where an e-invoice is not successfully delivered to government systems, suppliers will also receive an email notification within three working days, allowing faster follow-up and issue resolution.

This update further strengthens Singapore’s B2G e-invoicing framework by improving transparency, reducing manual effort, and accelerating invoice processing.
