The success of a business is often tied to maintaining positive cash flow. However, that doesn't mean that everything will go to plan. In fact, 32% of Singapore businesses said that maintaining adequate cash flow has been one of their biggest challenges according to a recent survey by Atradius Singapore. Late payments can also be detrimental to businesses, with 52% of Singapore businesses reporting that they are experiencing delays in payments.

There are a number of ways businesses can solve these cash flow problems. One is to stay on top of invoicing, which becomes easier for businesses that move away from the traditional, time-consuming manual- and paper-based invoicing processes and implement more efficient invoice processing workflows like electronic invoicing (e-invoicing).

Thanks to InvoiceNow, a Singapore e-invoicing initiative that uses the Peppol framework, doing so is easier and more advantageous for businesses that adopt it.

What is E-Invoicing?

E-invoicing (or electronic invoicing) automates the process of suppliers sending buyers an invoice using an integrated electronic format. With e-invoicing, an accounting or ERP system typically generates and/or accepts electronic invoices within an accepted standard or framework like Peppol.

With governments around the world launching initiatives to drive the adoption of e-invoicing, like the adoption of the Peppol framework for e-invoicing in Singapore, there's never been a more perfect time to solve your cash flow problems by improving your invoicing process.

Peppol E-Invoicing in Singapore

Pan-European Public Procurement On-Line or Peppol is an international network owned and maintained by OpenPeppol that allows registered businesses under its network to exchange electronic invoices and other documents.

In 2018, the InfoCommunications Media Development Authority (IMDA) became the first Peppol authority outside of Europe. As the Peppol authority in Singapore, the IMDA is responsible for:

  • Ensuring compliance with the Peppol technical and service standards.
  • Promoting the use of e-invoicing in Singapore.
  • Approving and certifying a Service Metadata Publisher (SMP). The IMDA has adopted a centralised SMP model in Singapore and appointed SGNIC as the country's SMP provider, serving as an address book for businesses who registered to receive e-invoices.
  • Approving and certifying Access Point Providers, a connectivity service that links business systems to the Peppol network
  • Approving and certifying Peppol-ready accounting or ERP solution providers that allow business users to send and receive e-invoices through the Peppol network.

What is InvoiceNow?

In January 2019, the IMDA launched Singapore's nationwide e-invoicing initiative, InvoiceNow. It adopts the Peppol framework to manage the transmission of invoices across financial systems without human intervention, increasing the speed of processing invoices, which can result in faster payments.

How Does Electronic Invoicing With InvoiceNow Work?

With InvoiceNow, businesses using Peppol-ready accounting or ERP systems can send and receive e-invoices to one another through the Peppol network.

Documents are transferred on the Peppol network using a standard XML format called the BIS (Business Interoperability Specifications) Billing 3.0, allowing the exchange of invoices even if they are not using the same accounting or ERP system.

This allows you to choose your preferred accounting or ERP system to connect to all approved systems under the Peppol network.

Peppol operates based on a four-corner model that allows businesses to exchange electronic documents over the Peppol network. In the four-corner model:

  1. The seller sends the invoice through its accounting or ERP system.
  2. The seller's accounting or ERP system converts the invoice into the standard BIS format.
  3. The seller's accounting ERP system will utilise the global directory to identify the receiver's accounting or ERP system.
  4. The buyer receives the invoice through its accounting or ERP system.

The Peppol Network uses a four-corner model involving the (1) seller, the (2) seller's accounting system, the (3) buyer's accounting system and the (4) buyer.
