E-invoicing software for the invoices you send.
Every invoice and credit note comes with an EN 16931 e-invoice file, beside the PDF your customer reads.
A PDF is not an e-invoice.
An e-invoice is a data file that your customer’s software reads without anybody typing it in again.
Ireland is moving to it between businesses from November 2028. Invoicer keeps your invoices as data from the start, so the file is made for you every time you issue one.

What Invoicer does today.
The hard part of e-invoicing is clean data. That part is done the moment you raise the invoice.
- A file with every invoice
- Download the UBL file beside the PDF for any invoice or credit note. Nothing extra to set up.
- VAT worked out once
- Irish rates, reverse charge and exemption reasons, the same on the PDF and in the file.
- The right identifiers
- Company details from the CRO register and VAT numbers checked on VIES, so the file names the right parties.
- Credit notes that point back
- A credit note names the invoice it corrects, as the standard requires.
- Self-billing as well
- Invoices raised for your contractors under Revenue section 71 get the self-billing version of the file.
- Your records, exportable
- Every invoice, with its PDF and its file, exported whenever you want them.
What it does not do yet.
- Send over Peppol
- Sending over the Peppol network needs a certified Access Point, and Invoicer is not connected to one yet. Download the file and send it through a Peppol provider.
- Receive e-invoices
- Invoicer is for the invoices you send. Receiving your suppliers’ e-invoices, which every business must be able to do from November 2028, needs your accounts software or a Peppol provider.
- Report to Revenue
- Invoicer does not send invoice data to Revenue. Real-time reporting starts with the large corporates in November 2028, and Revenue will write to each business it includes.
The technical detail of the file is on the compliance page.
Questions about e-invoicing.
Something else? Ask us and a person answers, usually within one working day.
What is e-invoicing?
An e-invoice is an invoice sent as structured data rather than as a document to look at. It follows the European standard EN 16931, so the customer’s software can read the seller, the lines, the VAT and the totals without anybody typing them in again.
Is a PDF invoice an e-invoice?
No. A PDF is a picture of an invoice, even when it is emailed, and Revenue excludes PDFs and scanned paper from its definition. Once Ireland’s e-invoicing rules apply to you, the structured file is the legal invoice. You can still send a PDF with it as a courtesy copy.
When does e-invoicing become mandatory in Ireland?
As Revenue has announced it: large corporates from 1 November 2028, when every business must also be able to receive e-invoices; VAT-registered businesses that also trade with businesses elsewhere in the EU from November 2029; and the EU-wide rules for business sales between EU countries from July 2030. Revenue publishes the detail on revenue.ie, and our guide keeps track of it.
What should I do before 2028?
Three things. Ask your accountant or your accounts software how you will receive e-invoices, which every business must be able to do from 1 November 2028. Keep each customer’s legal name, address and VAT number up to date, since an e-invoice carries them as data rather than as print. And if Revenue writes to say your business is in the first phase, plan for sending e-invoices and reporting them as well.
Which e-invoice format does Invoicer produce?
A UBL 2.1 file that follows EN 16931: the Peppol BIS Billing 3.0 specification for ordinary invoices and credit notes, and Peppol BIS Self-Billing 3.0 for self-billed ones. Those are the formats the Peppol network carries.
Does Invoicer send e-invoices over Peppol?
Not yet. Sending over the Peppol network needs a certified Access Point, and Invoicer is not connected to one today. You can download the file for any invoice and send it through a Peppol provider.
Can Invoicer receive e-invoices from my suppliers?
No. Invoicer is for the invoices you send, and for self-billed invoices you raise for contractors. Ask your accountant or your accounts software how you will receive e-invoices from November 2028.
Does Invoicer report to Revenue?
No. From November 2028 the large corporates in the first phase must also report part of each e-invoice’s data to Revenue in real time, and Invoicer does not connect to Revenue. Revenue will write to each business it includes in that phase.
