E-invoicing — electronic invoicing via structured data formats — is being mandated in more jurisdictions every year. Australia, the EU, Singapore, Malaysia, and dozens of other countries have either mandated it or are in the process of doing so. Here's what you need to know.

What Is E-Invoicing?

E-invoicing is not sending a PDF invoice by email. It's the exchange of invoice data in a structured electronic format (like PEPPOL or UBL) directly between business systems, without human intervention. The invoice data is machine-readable — your customer's accounting system can receive and process it automatically.

Sending a PDF via email is not e-invoicing. E-invoicing means the invoice data flows directly from your system to your customer's system in a structured format like PEPPOL.

How to Get Started

  • Check if your country has mandated e-invoicing and when
  • Register on your country's e-invoicing network (e.g., PEPPOL for AU/NZ)
  • Use invoicing software that supports the required format
  • Test with a few suppliers or customers before going live
  • Keep PDF invoices as backup during the transition

E-Invoicing in Matey

Matey supports PEPPOL-compliant invoice export for Australian and New Zealand businesses. You can send a standard invoice as normal — Matey handles the formatting and submission to the PEPPOL network automatically when your customer is PEPPOL-enabled.

If you're selling to government agencies in Australia or NZ, e-invoicing via PEPPOL is increasingly expected. Get set up now — it's a 10-minute process and unlocks faster payment from government clients.

Frequently Asked Questions

Do I have to switch to e-invoicing right now?
Depends on your country. In Australia it's optional but encouraged. In the EU, it becomes mandatory for large businesses in 2026 and smaller businesses in 2028. Check your local tax authority.
Is e-invoicing more secure than email invoices?
Yes. Invoices travel through a regulated network rather than email, which is vulnerable to interception and fraud. Invoice fraud via email is a growing problem.
What's PEPPOL?
PEPPOL (Pan-European Public Procurement OnLine) is an international e-invoicing network. Think of it as a postal network but for invoice data. Many countries use it as their e-invoicing infrastructure.
Will my customers need to do anything?
If they're also PEPPOL-enabled, the invoice arrives automatically in their system. If not, you can still send a PDF copy as well — the two aren't mutually exclusive.
