Checklist

What to put on an invoice

A clear invoice gets paid faster because the client can approve it without questions. Most invoices carry the same core details, and the generator above has a field for each of them.

  • Your business details: name, address and a contact email or phone number.
  • The client: the person or company you are billing and their address.
  • A unique invoice number: numbers that never repeat make records and follow-ups easier. See the invoice numbering guide.
  • Issue date and due date: the due date follows from your payment terms, for example Net 30. See what Net 30 means and the payment terms guide.
  • Line items: what you delivered, the quantity and the rate, so the client can match each charge to the work.
  • Totals: subtotal, any discount, tax where it applies, shipping and the balance due.
  • How to pay: bank details, a payment link or accepted methods. See invoice payment methods.

Tax rules differ by country and state. If you charge sales tax or VAT, check which details your tax authority requires on invoices; the invoice template essentials page covers the common requirements.

When a generator is enough and when software helps

A free generator suits occasional invoices: a handful a month, simple pricing and payments you track yourself. Once you send many invoices, need recurring billing, automatic reminders or online card payments, invoicing software saves time. The guides below compare the options, including what free invoicing software gives up and how much invoicing software costs.

Questions

Common questions

Is this invoice generator really free?

Yes. There is no account, no trial and no watermark on the PDF. The tool runs in your browser, and the site is supported by ads.

How do I save the invoice as a PDF?

Click Download PDF / Print, then pick Save as PDF (on Windows: Microsoft Print to PDF) as the printer. Only the invoice preview is printed, not the rest of the page.

Is my invoice data stored anywhere?

Only in your own browser, in local storage, so the form is still filled in when you come back. Nothing you type is sent to our server. Start a new invoice clears it.

How is the due date calculated?

The due date is the issue date plus the payment terms you pick, for example 30 days for Net 30. Choose Custom date if you want to type your own due date.

Is tax applied before or after the discount?

The generator subtracts the discount first and calculates tax on the discounted subtotal. Shipping is added after tax and is not taxed. Sales tax and VAT rules differ by location, so check what applies to you.
