Plain-language answer

InvoiceNow is Singapore’s nationwide e-invoicing network based on the Peppol interoperability framework. In-scope GST-registered businesses are being brought into the GST InvoiceNow Requirement in phases; the applicable date depends on factors such as registration route and 2025 supply value.

Decision framework

Turn the requirement into a controlled plan.

1

Confirm scope and date

Use current IRAS guidance and your GST facts; do not rely on a generic deadline.

2

Map systems and flows

Identify where invoices originate, change, are approved and reach the ledger.

3

Choose a route

Compare an InvoiceNow-ready solution with an Access Point route based on your current systems. Onboarding typically includes registering your UEN in the SG Peppol Directory; review the Peppol ID Singapore guide for the identity step.
