What Is PEPPOL B2G e-Invoicing
PEPPOL stands for Pan-European Public Procurement Online. It serves as a global framework for governments and businesses. They use it to exchange invoices and procurement documents in electronic form. The process stays secure, standardised, and interoperable every time.
In a PEPPOL e-invoicing setup:
- Suppliers generate invoices in the right PEPPOL format.
- Those invoices go through a certified eInvoicing Access Point provider for transmission.
- Government agencies receive them right away.
- The systems process everything digitally without delay.
The benefit comes down to simplicity:
- Suppliers skip PDFs and email attachments.
- Manual entry disappears too.
- Clean invoice data flows automatically.
- Machines read and validate it easily.
Why New Zealand Is Moving Toward PEPPOL B2G Enforcement
New Zealand picked PEPPOL as its national e-invoicing standard. The aim focuses on higher accuracy in transactions. Processing time drops noticeably. Payments happen faster for suppliers. The government wants a digital financial ecosystem. It should work well across public sector agencies. Fraud risks go down in the process.
The change ties into larger objectives:
- Treasury cycles speed up for better cash flow.
- Administrative workloads lighten for staff.
- Errors and mismatches happen less often.
- Relationships between suppliers and government strengthen.
- Financial transparency improves.
Global use of PEPPOL keeps expanding. New Zealand’s move to mandatory B2G e-invoicing fits right in. It lines up with top digital economies around the world.
New Zealand B2G e-Invoicing 2026 Requirements
B2B e-invoicing stays voluntary in New Zealand for now. Government Procurement Rules push the B2G side harder though. The mandate starts taking effect in 2026.
Compliance hits key milestones along the way:
From 1 January 2026
Government agencies handling more than 2,000 domestic invoices each year must:
- Send PEPPOL-formatted electronic invoices
- Receive PEPPOL-formatted electronic invoices
From 2027
Implementation rolls out in stages:
- Large suppliers face requirements based on annual revenue thresholds
- They submit e-invoices when working with those agencies
Additional requirements:
- PINT A-NZ serves as the mandatory format now
- NZBN (New Zealand Business Number) must be used on every invoice
- E-invoice archiving rules apply (7 years of retention)
These rules reach beyond NZ organisations. International suppliers contracting with New Zealand government entities follow them as well.
How PEPPOL B2G Invoice Generation Works
The PEPPOL network uses a four-corner model to handle secure data exchange.
Corner 1 – Supplier’s system
- Accounting software
- ERP systems
- Custom invoicing platforms
Corner 2 – Supplier’s Access Point Provider
- Validates the invoice
- Converts formats if necessary
- Transmits the invoice
Corner 3 – Receiver’s Access Point Provider
- Government agencies use designated providers
- Invoices arrive through that channel
Corner 4 – Government agency backend system
- Invoice processes automatically
- Verification happens quickly
- Payment queue forms without delays
This model lets suppliers and buyers use different systems and still communicate smoothly.
