Everything runs in your browser. Nothing is sent to a server, and closing this tab discards what you typed — so print or save before you leave.

This tab forgets. The app doesn't.

Closing this page discards everything you typed. The free EstimateBill app keeps every invoice, client and price on your phone, numbers them in sequence, and tells you who hasn't paid — offline, with no account.

What a valid invoice has to include

Requirements vary by country, but almost every tax authority expects the same core set. Missing one of these is the usual reason an invoice gets queried or a client's accounts team sends it back.

  1. A unique invoice number — sequential, never reused, so payments can be matched.
  2. Issue date and due date — "due on receipt" is a term, not a date; put a real one.
  3. Your business name, address and tax ID — GSTIN in India, VAT number in the UK and EU, EIN in the US.
  4. The client's name and address — the legal entity being billed, not just a contact's first name.
  5. An itemised description — what was delivered, quantity, unit rate and line total.
  6. Tax shown separately — the rate and the amount, not folded silently into the total.
  7. The total due and how to pay — bank details, UPI ID, or a payment link.

If you are registered for GST or VAT, your local rules may add more — reverse-charge wording, place of supply, or a specific document title. Check your own tax authority's guidance before relying on any template, including this one.

How to make an invoice with this generator

  1. Fill in your business details on the left. They appear on the invoice as you type.
  2. Add the client and give the invoice a number and dates.
  3. Add a line for each piece of work with a quantity and rate.
  4. Set your tax label and rate — GST, VAT, Sales Tax, or whatever applies to you.
  5. Press Print / Save PDF and choose "Save as PDF" as the destination.

The form controls are hidden from the printed page automatically, so you get the invoice on its own with nothing else.

Invoice vs estimate vs quote

An estimate is an approximation that can move as the work becomes clearer. A quote is a fixed price you are committing to. An invoice is a demand for payment for work already delivered. The three often carry the same line items, which is why retyping them is such a waste — the EstimateBill app turns an accepted estimate into an invoice without re-entering anything.

Questions

Is this invoice generator really free?

Yes. There is no sign-up, no email and no watermark on what you print. It runs entirely in your browser.

Is my invoice data uploaded anywhere?

No. The generator is plain HTML and JavaScript running on your own device. Your figures are never sent to a server, and closing the tab discards them.

How do I save it as a PDF?

Press the Print button, then choose "Save as PDF" as the destination in your browser's print dialog.

Can I add GST, VAT or sales tax?

Yes. Enter any tax rate and label it whatever applies to you. Tax is calculated on the subtotal after any discount.

Can I save invoices and reuse clients?

Not in the browser tool — it is deliberately stateless. The EstimateBill app keeps clients, saved items and a full invoice history on your phone.
