What Revenue expects
The four rules of Irish invoicing
Sequential numbers
Invoice numbers must run in order with no gaps, and Revenue checks. The generator bumps yours automatically.
VAT broken down by rate
A mixed invoice must show net and VAT separately for each rate. The totals section does this for you.
VAT number if registered
Registered? Your VAT number must appear. Not registered? Charge no VAT and skip the field.
Keep records 6 years
Download and keep a copy of every invoice. Revenue requires six years of records.

Questions
Questions people ask
What must an Irish invoice include?
A VAT invoice must show: your name and address, your VAT number, an invoice number and date, the customer’s name and address, a description of the goods or services, the net amount per VAT rate, the VAT rate(s) and VAT amount, and the total. This generator produces exactly that layout.
I’m not VAT registered. Can I still use this?
Yes. Pick 0% on each line so no VAT is added, leave the VAT number field empty, and write "Not registered for VAT" in the notes field. Businesses below the registration thresholds (€42,500 services / €85,000 goods) issue plain invoices with no VAT on them, and must not call the document a "VAT invoice". Our guide to invoicing without a VAT number explains why.
Which VAT rate do I put on my invoice?
The rate that applies to what you sell: 23% standard for most services and goods, 13.5% for construction, repairs and fuel, 9% for hospitality and hairdressing, 0% for exports and certain goods. Each line can carry its own rate, and the totals break VAT down by rate as Revenue expects.
What is the reverse charge checkbox for?
In certain cases (most commonly subcontractors under RCT in construction) VAT is accounted for by the customer, not the supplier. Tick the box and the invoice shows no VAT plus the required wording that the recipient accounts for it.
How should I number invoices?
Sequentially, with no gaps. That’s a Revenue requirement. Any format works (INV-001, 2026/17) as long as it increments. The "New invoice" button bumps your number automatically so the sequence stays intact.
PDF or Word: which should I send?
PDF for sending (it can’t be edited and renders the same everywhere). Word if you want to make further edits or apply your own branding first. This tool gives you both, free.
Is my data stored anywhere?
Only in your own browser, so your details are pre-filled next time. Nothing is uploaded: the invoice is generated entirely on your device. See the privacy policy for details.
How long do I have to keep invoices?
Revenue requires businesses to keep records, including invoices, for six years. Download and store a copy of every invoice you issue. The generator does not keep copies for you.
Sources
Sources and method
The generator lays out the fields Revenue requires on a VAT invoice: a sequential number, the issue date, your name, address and VAT number, the customer’s details, a description of each line, the net amount, the VAT rate and VAT amount per rate, and the gross total. Totals are worked out in your browser from the quantities and unit prices you type, using the current Irish rates (23%, 13.5%, 9%, 4.8% and 0%), and the PDF or Word file is built on your own device. Nothing is uploaded.
It does not file anything with Revenue, check that a VAT number is valid, or decide which rate applies to your goods or service. If you are not VAT registered, leave the VAT fields blank and the document becomes a plain invoice. For rates, reverse charge rules and what to do about late payment, use the sources below.
