How to Make an Invoice

An invoice is not a design problem. It is a checklist — nine pieces of information, and if one is missing, your payment stalls in someone’s inbox while they email you about it. Most "free" invoice makers solve this by making you sign up, watermarking your document, or quietly keeping your client list. The generator below does none of that: it runs entirely in your browser, nothing you type is uploaded anywhere, and the PDF is yours in about two minutes.

What every invoice needs — the animated tour

Watch the highlight move through a real invoice, part by part. These nine elements are the same whether you’re a freelance designer in Sydney or a plumber in Leeds — only the tax lines change by country.

The two-minute method

First, fill in Your business once and hit Save on this device — the generator remembers your details and logo in your own browser, so invoice number two takes thirty seconds, not two minutes. Second, add the client and the line items, being specific: "Bathroom retile — labour, 14 hrs @ $95" beats "work done" every single time an accounts person reads it. Third, check the tax line matches your situation — the country selector sets the right label and rate, and you can switch tax off entirely if you’re not registered. Finally, hit Download / Print PDF and choose "Save as PDF" in your browser’s print dialog.

Send the PDF, not an editable document. A PDF looks the same on every screen, prints cleanly, and is far harder for anyone to tamper with in transit — which matters, because the most common invoice scam is a criminal intercepting an editable invoice and changing the bank details before it reaches your client.

Invoice, quote or receipt?

These three documents get mixed up constantly, and the mix-up costs real time. A quote comes before the work — it says what the job would cost, and commits nobody to payment. An invoice comes after (or during) the work — it says what is now owed, by whom, and by when. A receipt comes after payment — it proves what was paid. Accounts teams process each differently, which is why the document’s name belongs at the top in large letters. Send an invoice titled "Quote" and it will be politely filed and never paid.

Numbering that won’t embarrass you later

Pick one sequence and never break it: INV-0001, INV-0002, onwards forever. Tax authorities in every country covered on this page expect invoice numbers to be unique and broadly sequential — an audit that finds two invoices numbered 0007 asks awkward questions. The generator above keeps a counter on your device and suggests the next number automatically. One professional trick: don’t start at 0001. Starting at, say, 0041 avoids announcing to your very first client that they are your very first client.

Getting paid faster

Three changes reliably shorten the gap between sending and getting paid. Name a real date — "Due 19 July 2026" outperforms "due on receipt", which many clients treat as a suggestion. Put your payment details on the invoice itself, so paying you never requires a reply email. And invoice immediately: an invoice sent the day the work finishes lands while the value is fresh; one sent three weeks later joins the end of the queue. If a client is habitually late, shorter terms (7 days instead of 30) and a polite late-payment line in your notes both help — but nothing helps as much as invoicing promptly and making payment frictionless.

Invoice rules by country

The nine-part checklist is universal; the tax lines are not. Each guide below covers exactly what your tax office expects on an invoice — with the generator preset to that country’s rules.
