Invoice Generator - free online tool cover illustration

Create Professional Invoices Free (Download as PDF)

Freelancers, contractors, and small shops lose hours to invoicing, or worse, send sloppy invoices that delay payment. The free Invoice Generator from ZeroFee Tools fixes that: fill in your business and client details, add line items, and download a clean, professional PDF in minutes. Everything happens in the Builder tab (business details, client details, items, tax, discounts), and your data never leaves your device.

How do I create a professional invoice for free?

Fill in your business details and client details in the Builder tab, add line items with quantities and rates, set tax and any discounts, and upload your logo. The generator produces a clean, professional invoice you can download as PDF in minutes. No account, no templates locked behind paywalls.

Include a due date and payment method on every invoice to shorten payment cycles.

Is my business data safe in an online invoice generator?

With this one, yes: everything you type stays in your browser and is never sent to a server, so client names, rates, and tax details remain private. Many free invoice tools store your data in the cloud or require an account; this generator works entirely locally with nothing to sign up for.

Save the downloaded PDF with a clear filename like Invoice-1042-Acme.pdf.

Everything happens in the Builder tab - business details, client details, items, tax, and discounts - with a live FAQ tab answering common questions as you work. Your logo and data stay on your device; nothing is uploaded anywhere.

How to use the Invoice Generator in 5 steps

  1. Start a fresh invoice. Hit “New invoice” to clear the Builder and start clean. (Use “Clear all” any time you want a blank slate.)
  2. Add your business details. Enter your Business name, Address, Email, and Phone. Upload a Logo if you have one - it stays on your device and appears on the PDF header.
  3. Add the client and invoice details. Fill in Client name, address, and email, then set the Invoice number, Currency, Issue date, and Due date. A clear due date gets you paid faster.
  4. Build the line items. Click “+ Add item” for each product or service, with quantity and rate. Then set Tax % and Discount % - totals calculate automatically.
  5. Download the PDF. Hit “Download PDF (free)” and send it to your client. Save a copy for your own records before you start the next one.

Where is my business data stored?
