Nationwide E-Invoicing Framework

last updated 05 April 2019

IMDA has implemented the nationwide E-Invoicing framework with the industry. The e-invoicing network is live from 9 January 2019 with certified Access Point providers offering services to help businesses improve efficiency, reduce cost, enjoy faster payment cycles, access to new financing options and build a strong foundation for digitalisation.

What is E-Invoicing?

Electronic invoicing or E-invoicing is the automated creation, exchange and processing of request for payments between suppliers and buyers using a structured digital format.

Benefits of E-Invoicing

E-invoicing brings about benefits to businesses in the following area:

  • Cost reduction: moving from paper to electronic invoices eliminates or reduces several costs to businesses, such as invoice transportation, manpower costs and archiving. It also improves accuracy which saves in error correction costs.

  • Faster payment cycles via improved verification and validation: E-invoicing can accelerate invoice processing times by mandating that “required fields of information” are completed before e-invoices are sent. This would allow validation to be speedily completed and payment to be released. With the further application of rule-based processing (including the potential for artificial intelligence), human intervention could be further reduced and processes speed up.

  • Access to new financing options: E-invoicing allows for accurate and real time visibility of the status of payment cycles, enabling more efficient cash flow management for business sustainability and growth planning. E-invoicing also has the potential to enable supply-chain financing in near-real-time, facilitating greater efficiency and transparency that could increase working capital and liquidity.

  • Leveraging data analytics: Businesses that migrate to e-invoices can use data analytics to help identify potential fraud or human errors, and AI-enabled solution could further enhance such activities and extend benefits across large volumes of transactions quickly.

  • Business-to-Business (B2B) Benefits: While there are already significant motivations for businesses to adopt e-invoicing, e-invoicing also has the potential for wider B2B ecosystem benefits. Some of these include development of new services (e.g. advanced accounting services) and ecosystem multiplier effect.



The open standard “Pan-European Public Procurement On-Line (PEPPOL)” will be adopted to provide standards-based mechanism of exchanging invoices in structured format. The PEPPOL standard is maintained by OpenPEPPOL, a non-profit international association. It was conceived in the European Union in 2008, with OpenPEPPOL established in 2012. It has 304 members from 32 countries, with 199 Access Points in 23 countries in Europe and North America, that serve to connect over 160 thousand entities. PEPPOL conducted over 85 million e-invoices in 2018. Please visit PEPPOL’s website for more details.

IMDA has joined OpenPEPPOL as the first PEPPOL authority outside of Europe, and the first country in Asia. As the PEPPOL Authority, the IMDA will be able to set national rules and specifications that meet Singapore’s domestic requirements, as well as appoint and certify Service Metadata Publishers (SMP) (colloquially called the address book) and Access Point (AP) providers. We will also ensure conformance to the PEPPOL technical and service standards.


How PEPPOL e-invoicing works

Companies who wish to adopt e-invoicing must subscribe to an AP provider or third parties (eg. Accounting Platforms) who are connected to the Access Points. Companies then send their e-invoices to their AP provider, which checks and verifies the receiving company’s PEPPOL address through the SMP (the SMP service is offered as a free service in Singapore by Singapore Network Information Centre, or SGNIC). The AP provider then sends the document to the relevant receiving AP provider, and then onward to the receiving party.


Sample of sending an e-invoice on the PEPPOL network

Senders/Receivers can either connect directly to an Access Point or through third parties (eg. Accounting platforms) who are connected to Access Points.


Government Agencies Leading E-Invoicing

IMDA is working with several key government agencies, such as Accountant General’s Department (AGD), to drive the adoption of e-invoicing.

AGD is joining the nationwide e-invoicing framework to provide government vendors with greater options when transacting with the Government, in addition to the current Vendors@Gov system. AGD will be sourcing for a service provider in the coming months.

The Singapore Government is committed to coming onboard the nationwide e-invoicing network and more details will be provided later in the year.
