Frequently asked questions

Is this invoice generator really free?

Yes. Creating, previewing, printing and downloading invoices is free, with no account and no usage limit.

Do you store my invoice data?

No. Your invoice is calculated and rendered in your browser. Drafts you save stay in this browser's local storage on this device.

Can I use the PDF for tax purposes?

PDFs follow common invoicing practices for each country, but requirements vary by jurisdiction, business type and transaction. Verify local requirements with a qualified professional.

Which paper size does the PDF use?

A4 by default, or Letter for the United States, Canada and Mexico. You can switch at any time.

Can I add my logo and brand colour?

Yes. Upload a logo and pick an accent colour — both are processed locally in your browser.

Does it work on a phone?

Yes. The builder is mobile-first, and you can save the PDF from your phone's print dialog.
