How does Peppol e-invoicing work and how will it help Australian businesses?

E-invoicing is not a new concept, and electronic invoices have been around for a while in several different formats, standards, and names - all claiming to connect buyers and suppliers digitally and more efficiently.

The issue was that many e-invoicing systems were expensive and time consuming to set up. This meant that it was only something large businesses, who typically had a big volume of orders or invoices to process, considered implementing, and the lack of a consistent and single format and framework for e-invoicing kept it from being widely adopted.

The turning point for e-invoicing has been the adoption of a globally recognised standard for sending e-invoices and e-orders, known as Peppol (Pan-European Public Procurement OnLine). This standard enables anyone who is part of the network to send e-invoices and e-orders easily and safely to each other. The standard also enables a simple and accessible way for businesses to be onboarded onto the network.

There are already 200,000+ businesses across 34+ countries on the Peppol network. Australia, New Zealand, and Singapore have all adopted the standard as the basis for their latest e-invoice mandates.

Peppol e-invoices are sent and received in the following steps:

Step 1. The supplier generates an invoice from their accounts receivable system for the buyer and it is sent electronically to their Certified Peppol Access Point, this is typically done via an integration between the supplier’s system and the access point provider. Note – an Access Point acts as a gatekeeper in the network to ensure that each invoice is in the right format, valid and the sender is who they say they are, so it gets to the right receiver.  

Step 2. The sender's Peppol Access Point validates the invoice to make sure that it can be sent via the Peppol network. They check if the supplier is legitimate and that the receiver can receive the invoice. The sender's Access Point finds the buyer's Access Point and sends it electronically to them.

Step 3. The buyer’s Access Point receives the validated invoice and processes it directly to the buyer's accounts payable system. This is typically done via an integration between the buyer's system and the Access Point provider.

Step 4. The supplier's invoice is automatically entered into the buyer’s system. There is no need for any party to do any manual data entry or validation. The whole process takes a matter of minutes. It is highly secure and very easy to use.

As adoption of Peppol e-invoicing continues to grow in Australia and APAC, more and more businesses are starting to investigate how they can get started. One of the first questions that comes up in many of the conversations I’m having is how much Peppol e-invoicing costs? There is not a simple answer, but the ATO recently approximated the cost of processing an invoice in three ways, comparing the cost of processing a paper, PDF and e-invoice. The differences are clear:

  • Paper invoices - approximately $30 per invoice
  • PDF Invoices - approximately $27 per invoice
  • E-invoice - less than $10 per invoice

Multiplying these figures by the number of invoices you send and receive on a daily, weekly, or monthly basis (ie. your invoice volume over a given period) gives you an idea of the total cost for each type of system and the savings you could be making by adopting Peppol e-invoicing.

However, as there are several different Certified Peppol Access Point providers across Australia and New Zealand, the costs involved with each provider varies. But there are usually two main costs to consider, and businesses should make sure their providers’ pricing structure reflects its ability to scale, as the number of transactions, e-invoices, or e-orders they send or receive grows over time:

  • An implementation fee – this covers the initial setup of your Access point and integration into your finance systems. That could cover an integration from your accounts payable platform into your access point, an integration from your accounts receivable platform into your access point, or both.
  • Monthly subscription fee – Once your finance systems are connected to your access point there is usually a monthly Peppol subscription fee. This covers the costs involved in sending and receiving business documents (e.g., e-invoices, e-orders) via the Peppol Network.

Remember to make sure that any subscription or monthly fee is volume-based, so that you are only paying for what you use. With greater discounts available for greater volumes, the average cost per business document sent or received should go down as your volumes increase.
