Who runs this site
Free Invoice Generator is operated by me, Mikhael Benjamin Santoso. Where the terms and the privacy policy say "we" or "us", they mean me.
Why it exists
The aim is narrow: let anyone produce a correct, downloadable invoice in a browser without an account. It's built for the person who needs to send one invoice today and has no accounting software: a freelancer, a contractor, a small business invoicing across borders, someone who invoices once a year.
It isn't meant to be where your records live. There is no account and no history held on my side. The trade-off is that your invoices are saved in your browser, so clearing your browser data removes them for good, and the PDFs you download are the copies to keep.
What it is
A free invoice generator that needs no account. Invoice data is sent to the server only when you press Download PDF, to make the file. It is held in memory for about a second, not written to disk, not recorded in logs, and not kept after the PDF is sent. Alongside it are free calculators for the arithmetic around getting paid and plain guides to the parts of invoicing that are easy to get wrong.
How the guides and calculators are made
- Where a guide states a rule, it quotes the primary source (HMRC, the IRS, the legislation itself) and links to it, so you can read the original rather than take my word for it.
- Where a rule differs by country, the guide says which country its example comes from, and doesn't present the rule as universal.
- The calculators do arithmetic only. They don't know your tax rate, your payment terms or what you may charge. You supply those, because they depend on where you are and what you agreed.
- Every change is checked against an automated test suite that drives the pages in a real browser, including the arithmetic of every calculator.
- Every page carries the date it was last updated.
Sources and licences
Facts such as tax rates, deadlines and legal requirements are restated in my own words, with a link to the page they come from. Where a guide quotes a source word for word, the quote is short, in quotation marks, and linked. Material from official sources is used under the terms those sources publish:
- United Kingdom (GOV.UK, HMRC, legislation.gov.uk, the Small Business Commissioner): contains public sector information licensed under the Open Government Licence v3.0.
- New Zealand (Inland Revenue and other agencies): Crown copyright material, reused under the Creative Commons Attribution 4.0 licence.
- Australia (business.gov.au): © Commonwealth of Australia, under the Creative Commons Attribution 3.0 Australia licence. The ATO's pages are cited for their facts and linked, not reproduced.
- European Union (EUR-Lex, the European Commission): © European Union, reused under the Commission's reuse policy, which allows reuse with the source acknowledged.
- European Central Bank (euro foreign exchange reference rates): ECB data, used with the ECB cited as the source. The exchange rate risk calculator works out cross rates and changes from them, which are its own calculations, not ECB figures.
- United States (the IRS, the eCFR and other federal sources): works of the US federal government, which are not subject to copyright in the United States.
- Everyone else, including the CRA and other national tax authorities, courts and legislatures: cited for their facts, which are restated here and linked to the original, with short quotations marked as such.
None of these sources endorses this site. If you hold the rights to something quoted here and want it changed, get in touch.
What it is not
It isn't accounting software, a payments processor, or a place to keep client records. Nothing on this site is legal, accounting or tax advice either. It explains how invoices and the sums around them work. What applies to you depends on your jurisdiction and your agreements, and I recommend asking a professional who knows both.
Corrections
If a guide or a calculator is wrong, please tell me by email. A corrected page gets a new "last updated" date.
