Build a Peppol A-NZ e-Invoice (BIS Billing 3.0, UBL)

Skill: Convert invoice data into the Australian Peppol (A-NZ) UBL e-invoice

Region: Australia Category: E-Invoicing — Peppol A-NZ (EN 16931-aligned) Does: Takes ordinary invoice data and produces a UBL 2.1 Invoice in the Australia/New Zealand Peppol BIS Billing 3.0 profile, routed over the Peppol network (the ATO is the Australian Peppol Authority) to the buyer's access point. Standard: Peppol BIS Billing 3.0 — A-NZ specialisation (aligned to EN 16931) · ATO Peppol Authority

Australian e-invoicing is voluntary but standardised on Peppol: government agencies must be able to receive Peppol e-invoices, and the A-NZ profile constrains the international BIS Billing 3.0. Parties are identified by ABN using Peppol scheme 0151. GST is 10%. Validate against the A-NZ BIS schematron before sending.

When this applies

• B2B / B2G invoicing where the recipient is registered on the Peppol network with an A-NZ endpoint.
• Cross-Tasman (AU↔NZ) invoicing using the shared A-NZ profile (NZ uses NZBN scheme 0088/0088-GLN or the NZBN scheme).

Document structure (UBL Invoice)

├── cbc:CustomizationID  (urn:cen.eu:en16931:2017#conformant#urn:fdc:peppol.eu:2017:poacc:billing:international:aunz:3.0)

├── cac:TaxTotal  (TaxSubtotal: GST category S @10%, or Z/E/O)

GST category codes: S standard (10%), Z zero/GST-free, E exempt/input-taxed, O out of scope. ABN endpoints use Peppol EAS 0151.

Calculation rules

• Line net = quantity × unit price; group lines by GST category → TaxSubtotal (TaxableAmount, TaxAmount = base × 10%).
• TaxInclusiveAmount = TaxExclusiveAmount + GST; PayableAmount = TaxInclusiveAmount − Prepaid.
• GST-free / input-taxed lines carry rate 0 with the appropriate category and reason.

Validation checklist

• A-NZ CustomizationID / ProfileID used; currency AUD
• Supplier & customer ABN endpoints with schemeID="0151"
• Each line: quantity (unitCode), price, GST category + rate, line total
• GST TaxSubtotal reconciles; GST-free/input-taxed lines categorised correctly
• TaxInclusiveAmount = exclusive + GST; PayableAmount correct
• Passes the A-NZ Peppol BIS schematron; recipient reachable on Peppol

Last updated: 2026-06-04 — confirm the active A-NZ Peppol BIS Billing version, ABN endpoint scheme, and schematron against the current ATO Peppol Authority specifications before use.
