Free Online AI Invoice Generator

Free invoice generator for a ready-to-download PDF

Create an invoice online with your business details, client information, item descriptions and logo. ToolNivo’s invoice maker updates the amounts while you edit and shows a page-by-page preview. Download the invoice as a PDF or print a clean copy without the website’s navigation.

The editor uses one professional invoice layout. There is no signup, payment requirement or automatic draft saving. It is designed for creating individual invoices, not for tracking payments, sending reminders or managing an accounting ledger.

How to create an invoice

1. Enter your business name and contact details, then add your client’s billing information.
2. Set the invoice number, invoice date, due date and currency. Add a purchase-order number if you need one.
3. Add each product or service with a description, quantity and unit price. Use the move buttons to reorder items.
4. Enter any discount, tax, shipping charge and amount already paid. Check the balance due in the live preview.
5. Add optional notes, terms or payment instructions. Choose a file name and select Download PDF.

What information should an invoice include?

Give the recipient enough information to understand who is billing them, what was supplied, when payment is due and how to pay. Business and client contact details, an invoice reference, itemized amounts, currency and payment instructions help make those details clear. The optional Tax/VAT field records the number you enter; the tool does not verify registration or determine tax obligations.

This is a general invoice builder. Required details and tax treatment can differ by location and transaction, so review your invoice for your own requirements before sending it.

How invoice totals are calculated

Unit prices are rounded to the selected currency’s normal decimal precision. Each line equals quantity multiplied by that rounded price, with the line amount rounded to the same precision. The subtotal is the sum of those line amounts.

A percentage discount is calculated on the subtotal, or you can enter a fixed discount. Tax applies to the subtotal after discount. Shipping is added separately, or included in the tax base when you enable that option. Total equals subtotal minus discount plus tax plus shipping. Balance due equals total minus amount paid; an overpayment appears separately as a credit, rather than a negative amount due.

Calculations use decimal strings and integer minor units with half-up rounding. The selector supports currencies including USD, EUR, GBP, MAD, CAD, AUD, JPY, CHF, AED and SAR. It changes the currency and precision only; it does not convert exchange rates.

Download an invoice as PDF or print it

Review the live invoice pages before downloading. Normal item rows stay together when a page fills up. An exceptionally long description continues on another page with a continuation label. Table headings repeat, and notes and terms can continue across pages without being cut off.

Supported Latin text remains selectable in the PDF. Text lines using characters outside the PDF font are rendered as images by your browser to retain their appearance; those particular lines may not be selectable. Logos are processed locally, with transparent PNG pixels preserved.

Print Invoice prints only the invoice pages. Disable your browser’s own headers and footers in the print dialog if it adds a URL or date. To combine a downloaded invoice with attachments, use Merge PDF. You can extract pages with Split PDF or create supporting documents using Text to PDF.

Privacy for business and customer details

The editor, calculations, logo processing and PDF generation run in your browser. Invoice contents are not uploaded or automatically saved to browser storage. The page loads the software needed to generate your PDF, but those asset requests do not include your invoice information. Download your work before closing or reloading the page.
