Free Online Invoice Generator

How to make an invoice online

An invoice is the document you send once work is done, asking to be paid. To make one, add your business details, your client's details, a list of what you did or sold with a price for each line, then a due date and how you want to be paid. Fill in the fields on the left and watch the invoice build itself on the right, then download it as a PDF and send it to your client.

1. Add your company name, logo, and banking details so the client knows who is billing them and where to pay.
2. Add the client's name and contact details, then set an invoice number and due date.
3. List each item or service with a description, quantity, and price. The generator adds up line totals and tax on its own.
4. Download the finished invoice as a PDF and email it, or print it if your client prefers paper.

What to include on a professional invoice

A client can only pay you correctly if the invoice format tells them exactly what they owe and how to pay it. At minimum, every invoice needs:

• A unique invoice number, so you and the client can track which invoices are paid, open, or overdue.
• The issue date and a due date, either a fixed date or terms like "net 7" or "net 30".
• Your business details and the client's billing details.
• Line items, each with a description, quantity, unit price, and line total.
• A subtotal, tax, and the final total due.
• Banking details or a payment link, so the client knows exactly where to send the money.

Invoice vs quote vs proforma invoice

A quote is sent before the work starts and is not a request for payment, it is a proposed price the client can accept or negotiate. A proforma invoice sits in between: it looks like a real invoice and is often used for imports or upfront deposits, but it is not a final demand for payment either. An invoice is the real thing, sent once work is complete or goods are delivered, and it is what you and your client's accountant use for tax and bookkeeping records.
