Invoice generator
Fill in the fields and the invoice takes shape beside them. The generator breaks VAT down by rate, applies the withholding if it applies to you and adds up the total. When it is ready, print it or save it as a PDF from the browser itself. Nothing is sent to any server.

Mandatory content
These are the ones the Spanish invoicing regulation lists for a complete invoice. You fill in the first seven above. The eighth depends on your case and has to be written by hand.
Numbering runs consecutively within each series, with no gaps and no repeats. You can keep several series, but each one has its own count.
The day you issue the invoice. If the transaction happened on a different day, that second date goes in as well.
Name or company name, tax ID and registered address of whoever issues the invoice. All three, not just the name.
The same three details for the recipient. Between companies and professionals, the customer's tax ID is not optional.
A description of the transaction with what is needed to determine the net amount: item, quantity and unit price before tax.
The rate applied and the VAT charged, stated separately. If the invoice mixes rates, each one with its own net amount and VAT.
The sum of net amounts and VAT, minus the IRPF withholding where it applies. It is the amount to be collected.
Exempt transactions, reverse charge or the cash accounting scheme: the invoice has to say so and cite the provision. The generator does not write them because it cannot know which one is yours; add them before you hand it over.
An invoice missing one of these details is not half an invoice: it is an invoice your customer may not be able to deduct, and it may cost you an adjustment.

Complete or simplified
What this page produces is a complete invoice, the one that is always valid for everyone. The simplified invoice, what used to be called a receipt, is an option with an amount cap, not a shortcut you can take whenever you like.
Up to €400
VAT included. It carries a number, a date, the issuer's details, the VAT rate and the total, but it does not identify the recipient.
Up to €3,000
Retail, hospitality, passenger transport and a few more cases the regulation lists. Outside that list the cap is still €400.
No cap
Above €3,000 there is no alternative, and below it nothing is forbidden either: always issuing complete invoices is the safe option, and it is the one that comes out of here.
With a simplified invoice your customer cannot deduct the VAT, because they are not named as the recipient. They can ask you to include their tax ID and address, and then they can; at that point it is simpler to issue a complete invoice from the start.

The figures, with their source
The generator applies the rates in force in Spain and no others. Here are the five, each with the rule that sets it and the year in which it is in force.
AEAT · VAT Act 37/1992 · rates in force in 2026
Royal Decree 439/2007, IRPF Regulation, art. 95 · in force in 2026
These are guideline figures so that your invoice adds up, not tax advice. Your VAT rate depends on what you sell and your withholding on your situation: if in doubt, ask the AEAT or your accountant before issuing.
Check VAT, withholding and take-home in the calculatorWhat this sheet lacks
An invoice made on a standalone website is a correct piece of paper: it carries the details the regulation asks for and the maths adds up. What it does not carry is anything the law requires of the system that issues it, and writing it better does not fix that.
You write the number yourself and nobody checks that it is the next one in the series. Nothing stops you repeating 12 or jumping from 30 to 32, and consecutive numbering with no gaps is mandatory.
Since Royal Decree 1007/2023, the software that issues invoices has to generate an invoicing record for each one. It applies to companies from 1 January 2027 and to everyone else from 1 July 2027. This sheet generates none.
On a verifiable invoice each record chains the hash of the previous one, and the document comes out with a QR code your customer can use to check on the AEAT website that it exists. Here there is neither hash nor code.
Close the tab and nothing is left: not the invoice, not who you issued it to, not what you are owed. Issued invoices have to be kept for four years, which is how long the tax office can ask you for them.
None of this is a problem if you invoice twice a year. If you invoice every week, it is the reason invoicing software exists, and not the other way round.
What VeriFactu is and when it starts applying to youCommon questions
As a document, yes: it carries the content the Spanish invoicing regulation requires and the maths is done. What a standalone website cannot give you is what the law asks of the issuing system, which is guaranteed numbering, an invoicing record and safekeeping. That is what separates invoicing once from invoicing always.
Ten days' trial, no card. The app keeps the numbering and the record comes out with every invoice.
