Invoicing the Irish Government via Peppol

Becoming a registered government supplier

Before you ever issue an invoice, most Irish public sector contracts are won through eTenders (etenders.gov.ie), the national procurement portal, or via a framework agreement managed by the Office of Government Procurement (OGP). Once you're an approved supplier — whether from a one-off tender award or a standing framework — the buying body will issue purchase orders against which you invoice.

Being Peppol-ready is separate from winning the contract. Suppliers are not legally required to send e-invoices to public bodies, but several bodies prefer or require structured or Peppol invoices, so check the contract and purchase order terms for the invoicing format the buyer expects.

Why public bodies accept e-invoices

EU Directive 2014/55/EU requires public administrations across the EU to be able to receive and process electronic invoices in the EN 16931 standard. In Ireland it was transposed by S.I. 258/2019: public bodies have had to be able to receive EN 16931 e-invoices since 18 April 2019 (central government) and 18 April 2020 (sub-central). The obligation is on the public body, not on you. The goal is faster payment processing, fewer manual errors, and lower administrative cost on both sides.

Which Peppol ID do you invoice?

Every Peppol invoice must be addressed to the buyer's own Peppol ID, and there is no single ID for a sector. Each HSE area, county council and Education and Training Board has its own. Look the buyer up in the Peppol Directory (directory.peppol.eu), or ask the buyer or check the purchase order.

• Central government — departments and many state agencies
• HSE — health service bodies (see our dedicated HSE guide)
• City and county councils (see our dedicated county council guide)
• Education and Training Boards (see our ETB guide)

Check that the Peppol ID you use is the one for the specific body on your purchase order. For a general walkthrough, see our complete Peppol invoice Ireland guide.

What you need on every invoice

• The purchase order or contract reference issued to you
• Your registered legal entity name (matching your VAT registration, not just a trading name)
• Correct VAT treatment per line item
• A buyer reference, if one was provided — public bodies usually require a PO or buyer reference to route the invoice internally

Getting invoices out without an ERP system

You don't need SAP or Oracle to create a structured invoice. PeppolInvoice.ie generates a UBL 2.1 XML file built to EN 16931 / Peppol BIS Billing 3.0, and a matching PDF, from a simple web form — built for suppliers who send too few invoices a month to justify an enterprise integration. You upload the UBL file to your own Peppol Access Point to send it over the network, and we recommend validating the file with your Access Point.
