How to Make a Free Invoice (Fast)

Sending your first invoice — or just tired of wrestling with a spreadsheet template? You don't need accounting software to bill a client. Here's what belongs on a professional invoice and how to generate a clean PDF for free, right in your browser.

Make an invoice in three steps

Use the Invoice Generator:

1. Fill in your business details and your client's details.
2. Add line items (description, quantity, price), plus tax and any notes — the totals calculate for you.
3. Click Download PDF. Done.

What every invoice should include

• The word “Invoice” and a unique invoice number.
• Your details — name/business, address, and contact.
• Your client's details.
• Date issued and a due date.
• Line items — a clear description, quantity, and unit price for each.
• Subtotal, tax, and total.
• Payment terms / notes — how and when to pay.

The generator lays all of this out for you, so you just fill in the blanks.

Tips to get paid faster

• Number your invoices (001, 002…) so they're easy to track and reference.
• Set a clear due date — “due in 14 days” beats “due on receipt” for prompt payment.
• Spell out payment methods in the notes.
• Keep a copy — download and file every invoice you send.
