About The Nationwide E-Invoicing Initiative
IMDA implemented the nationwide E-invoicing network in 2019 to help businesses improve efficiency, reduce cost, enjoy faster digital payment, and stay green at the same time. As one of the leading e-invoicing solution providers, this network is an extension of the International Peppol E-Delivery Network allowing businesses to transact internationally with other linked companies.
An Overview of Singapore’s E-invoicing Journey
| 2018 | IMDA adopted Peppol as the standard for the nationwide e-invoicing initiative and became the first Peppol Authority outside of Europe. |
| 2019 | The network was launched with 11 Access Point providers. |
| 2020 | The Government public procurement was connected to Peppol, providing an additional channel for Government vendors to issue invoices to Government. |
| 2021 | IMDA rebranded Peppol to InvoiceNow in Singapore, drawing on the public’s familiarity with PayNow, the widely adopted e-payment system in Singapore. |
| 2022 | IMDA introduced additional document types – purchase order and invoice response, on the InvoiceNow network, aiming to further streamline the procure-to-pay process for businesses. |
| 2023 | The Government announced the plan to make InvoiceNow the default channel for public procurement in the next few years. |
| 2024 | IRAS announced the GST InvoiceNow Requirement, which requires GST-registered businesses to transmit invoice data to IRAS via the InvoiceNow network. The requirement will be implemented progressively, starting from November 2025. |
Peppol Authority
Peppol Framework and OpenPeppol
IMDA's nationwide E-invoicing network is built on the established Peppol framework to support exchange of business documents electronically and is used in many countries. OpenPeppol is the non-profit international association in charge of development and maintenance of the Peppol specifications. OpenPeppol delegates the authority over the implementation and use of Peppol specifications to the local Peppol Authorities. For more information on Peppol, please visit https://www.peppol.org/.
IMDA as the Peppol Authority
IMDA became the Peppol Authority in Singapore in May 2018 and is responsible for approving and certifying Peppol Access Point Providers in Singapore.
As the Peppol Authority, IMDA takes the responsibility of specifying country specific rules and technical standards under the Peppol framework. To create a complete ecosystem of providers, IMDA started accrediting Peppol-Ready Solution Providers (PRSP) in 2019. PRSP evolved to InvoiceNow-Ready Solution Providers (IRSP) in 2024 to incorporate GST InvoiceNow Requirement.
IMDA also governs the compliance and promotes the adoption of Peppol framework in Singapore.
SMP in Singapore
IMDA has adopted a centralised Service Metadata Publisher (SMP) model in Singapore and has appointed SGNIC as the SMP provider in Singapore. For more information on the SMP in Singapore, please visit https://www.sgnic.sg/smp.html.
The InvoiceNow network is served by service providers that meet a variety of business needs. Service Providers who are interested to become an IMDA-accredited InvoiceNow-Ready Solution Provider (IRSP) or Access Point Provider (AP) can find out more about the pre-approval process below:
