Free Invoice Generator: Create and Print a Professional Invoice

Getting paid starts with a clear request for payment. A tidy invoice tells the client what they owe, why, and by when, and it makes their accounts team's job easy, which is often what decides how quickly you are paid. This generator lays your details out as an invoice, checks the sums to the cent, and lets you print it or save it as a PDF.

How to use this generator

1. Enter your business details and your client's details.
2. Set the invoice number and the issue and due dates.
3. Add each item: a description, a quantity and a unit price. Use Add item for more, and × to remove a row.
4. Add a discount and a tax rate if they apply.
5. Add payment details and any notes.
6. Check the preview, then choose Print or save as PDF.

The example values are only there to show how it works. Replace every one before you send anything.

How the totals are worked out

Money is calculated in whole cents, not floating-point decimals, so totals never drift by a penny.

• Line amount = quantity × unit price, rounded to the cent
• Subtotal = sum of the line amounts
• Discount = subtotal × discount %
• Taxable amount = subtotal − discount
• Tax = taxable amount × tax rate
• Total due = taxable amount + tax

The tests cover the classic rounding traps, such as 0.1 + 0.2, and confirm that the parts always add up to the total. The tool warns you about negative quantities, invalid numbers and impossible percentages instead of producing a wrong invoice.

What makes an invoice easy to pay

Clear descriptions. "Website design, homepage and three inner pages" beats "Services".

A unique number. It lets both sides refer to the invoice without confusion.

Obvious dates and terms. State the due date, and consider stating what happens if payment is late.

Easy payment instructions. The fewer steps between an invoice and a payment, the faster it happens.

The right contact. Send it to the person who approves payments, not only to the person who hired you.

Tax and legal details

Invoice requirements vary by country and by type of business. Some places require a tax registration number, specific wording, a sequence of numbers without gaps, or particular formats. Others are more relaxed. This tool provides a tax rate field and an optional registration number field, but it does not know your local rules and does not look up tax rates. Check what applies to you, or ask an accountant, before relying on the output for official records.

Getting paid faster

Send invoices promptly, when the work is delivered or the milestone is reached, not weeks later. Agree payment terms before the work starts, not after. Ask for a deposit on larger projects; the project price calculator shows how to set one. If you work with clients abroad, our guide to getting paid internationally covers payment routes and hidden costs. Follow up politely when a due date passes.

Keeping records

An invoice is also a record of income. Keep a copy of every one you send, in a folder you can find later. To track what you have earned and spent across a month or a year, use the income and expense tracker. Records make tax time easier and show you which clients are worth the effort.

Common mistakes

Vague descriptions. They invite questions and delays.

Reusing numbers. It creates confusion in both sets of records.

Forgetting the due date. Without one, there is no lateness.

Sending it with the example text still in. Check every field before sending.

Assuming the tool stores your invoices. It does not. Save the PDF.

Assumptions and limits

This generator produces a printable layout from the details you enter. It is not accounting software: it does not store invoices, track payments, send reminders or produce electronic invoice formats that some tax authorities require. Currency is display only, and no exchange rates are applied. Everything happens in your browser. For a freelancer's overall approach to finding and pricing work, see our freelancing guide.
