Australia Peppol E-Invoicing Guide

Overview

Australia operates a Peppol-based e-invoicing framework governed by the Australian Tax Office (ATO) and aligned with the A-NZ Peppol authority. The country uses the PINT A-NZ (Peppol International) billing specification, a regional profile of the global BIS Billing 3.0 standard tailored for Australia and New Zealand. All invoices are denominated in AUD, and the standard GST rate is 10%.

Clearvo exposes a single REST API endpoint for AU invoice delivery. No local tax engine or ERP integration is required — your system provides the invoice data; Clearvo handles format conversion, digital signature, and Peppol network routing.

Mandate and Timeline

The ATO mandated Peppol e-invoicing for Business-to-Government (B2G) transactions from July 2022. Commonwealth agencies are required to receive Peppol invoices, and suppliers transacting with the Australian government must be capable of sending them via the network.

Business-to-Business (B2B) e-invoicing remains voluntary as of 2026, though adoption is accelerating due to ATO incentives and the broader Trans-Tasman alignment with New Zealand. The ATO continues to promote the standard as part of its broader digital economy strategy.

Format and Network

• Specification: PINT A-NZ (Peppol International A-NZ Billing 1.x)
• Network: Peppol four-corner model
• Endpoint scheme: EAS 0151 (Australian Business Number, ABN)
• Document format: UBL 2.1 XML
• Currency: AUD
• GST rate: 10% (standard taxable supply, taxCode: "S")

Participant identifiers use scheme 0151 with the ABN as the identifier value — a numeric string without spaces or hyphens. Both supplier and buyer must be registered Peppol participants, discoverable via the SMP/SML. The ATO operates as the Peppol Authority for Australia.

Required Fields

The following fields are mandatory under PINT A-NZ and must be present in every invoice submission:

Tax codes follow EN16931 conventions mapped to Australian GST categories. Zero-rated exports use Z; input-taxed supplies (e.g. financial services, residential rent) use E.

Integration Example

Send an AU invoice via the Clearvo API:

curl -X POST https://api.clearvo.io/v1/invoices \
  -H "Authorization: Bearer $CLEARVO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "country": "AU",
    "documentType": "invoice",
    "invoiceNumber": "AU-INV-2026-001",
    "issueDate": "2026-06-16",
    "dueDate": "2026-07-16",
    "currency": "AUD",
    "buyerReference": "PO-2026-001",
    "supplier": {
      "name": "Clearvo Technologies Ltd",
      "taxId": "51824753556",
      "endpointId": "0151:51824753556",
      "endpointSchemeId": "0151"
    },
    "buyer": {
      "name": "Australia Buyer AS",
      "taxId": "BUYERAU001",
      "endpointId": "0151:BUYERAU001",
      "endpointSchemeId": "0151"
    },
    "lines": [
      { "description": "Software consulting services", "quantity": 5, "unitPrice": 1000, "taxCode": "S", "vatRate": 10 }
    ]
  }'

The API returns a deliveryId on success, which can be used to poll delivery status.

Key Rules

• ABN format: Supplier and buyer taxId values must be valid 11-digit ABNs. Clearvo does not validate ABN check digits — your system must supply a registered ABN.
• Endpoint scheme: Always use 0151. New Zealand uses 0088 (NZBN); do not mix schemes across Trans-Tasman invoices.
• GST-inclusive pricing: PINT A-NZ expects line amounts exclusive of GST. The unitPrice field is the ex-GST unit price; Clearvo calculates the tax amount from vatRate.
• Buyer participation: The buyer must be a registered Peppol participant. Clearvo performs an SMP lookup before delivery; unregistered buyers will cause a pre-send rejection.
• No credit notes in pilot scope: Credit notes (documentType: "creditNote") use the same PINT A-NZ schema but require a billingReference linking to the original invoice number.
• Clearvo positioning: Clearvo is a developer-first Peppol access point. There is no bundled tax engine or compliance advisory layer — you own the tax determination; Clearvo owns the network delivery.
