Frequently asked questions
Everything people usually want to know before sending their first invoice with the tool.
Is this invoice generator really free?
Yes. Every feature on this site — including PDF download, all templates and multi-currency support — is free with no sign-up. The site is supported by ads, which is why there is no paywall and no watermark on your invoice.
Do I need to create an account?
No. There are no accounts. Open the page, fill in the invoice and download the PDF. Your draft is saved automatically in your own browser storage, not on our servers.
Is my invoice data sent to a server?
No. The generator, the tax calculations and the PDF rendering all run locally in your browser. Your client names, amounts and notes never leave your device.
Will the PDF have a watermark?
No. The PDF you download is a clean, single-page A4 document with no branding, no watermark and no promotional footer.
Can I use it for VAT or GST?
Yes. Set the tax label to VAT, GST or Sales Tax and enter your rate — the totals update live. For UK VAT invoices specifically, see the UK VAT preset page which pre-fills GBP and 20% VAT.
Does it work on my phone?
Yes. The layout adapts to mobile screens: you fill the form, and the live invoice preview appears below with a fixed action bar for downloading or printing.
Can I save an unfinished invoice?
Automatically. Anything you type is saved to your browser (localStorage) and restored the next time you visit — even after closing the tab. Clearing your browser data will erase it.
Is an invoice created here legally valid?
The document is a standard commercial invoice containing the details most jurisdictions require (parties, date, unique number, itemized amounts, tax). Whether it satisfies specific local rules — such as UK VAT invoice requirements — is your responsibility; see our UK guide for the checklist.
What is the difference between an invoice and a receipt?
An invoice is a request for payment issued before the money arrives; a receipt confirms payment after it. If your client already paid, issue a receipt instead — this generator makes invoices.
What payment terms should I use?
Net 14 or Net 15 is standard for freelance and small-business work; Net 30 is common for larger companies with accounts-payable processes. Whatever you choose, write it explicitly — the template has a terms field for exactly this.
