01How it works

Three steps, no sign-up.

Fill in the left-hand side

Your details, the client’s, and a line for each thing you did. The document redraws as you type, so what you are looking at is what will print.

Press Download PDF

Your browser opens its own print dialog. Choose Save as PDF and you get a proper US Letter file with selectable text: no watermark, no library, no upload.

Send it however you like

Attach it to an email, put it in a message, print it. It is your file. Nothing here sends anything on your behalf.

02 · Questions

The honest answers.

Is this invoice generator really free?

Yes, and there is nothing to sign up for. No account, no email address, no watermark on the document and no limit on how many you make.

How do I download the invoice as a PDF?

Press Download PDF. Your browser opens its own print dialog. Choose "Save as PDF" as the destination and you get a proper PDF with selectable text, at whatever paper size that dialog is set to, which is US Letter unless you have changed it.

Where is my data stored?

In this browser, and nowhere else. The invoice is kept in your browser’s own local storage so it is still here if you close the tab. Nothing is uploaded, because there is nothing here to upload it to.

Can I put my own logo on it?

Yes. Choose an image and it goes on the letterhead. It stays on this device: it is held in the page and in your browser’s storage, and never sent anywhere.

Can the customer pay through the invoice?

No. This makes the document; it does not take money. Put your bank details in the "How to pay" box and record the payment yourself when it arrives.

Can an AI assistant fill in this invoice for me?

Yes. An assistant can give you a link that fills in the client, the lines, the dates and the tax, written like this: https://www.invoicekoi.com/us/invoice-generator/#to=Halverson%20Build&item=Labor|3|hours|45&item=Copper%20pipe|2|m|12.50&terms=Net%2014%20days&tax=8. In a browser that supports WebMCP, an assistant working in the page can fill it in directly. Neither can touch your own name, your address or how you get paid: you type those, and they stay in this browser.
