Invoice Generator

How to use this tool

1. Fill in your business details and the client's details.
2. Add line items with a description, quantity, and rate — amounts and totals calculate automatically.
3. Set the tax rate, add notes or payment terms, and check the live preview.
4. Click Print / Save as PDF to produce the finished invoice. Save named drafts and business details on this device to reuse them.

How it works

Each line's amount is quantity × rate; the subtotal is the sum of all lines; tax is applied at your percentage to the lines you mark taxable (untick the Tax box on exempt items like some services or resale goods); and the total is subtotal − discount + tax + shipping. The preview is exactly what prints — site navigation and form controls are stripped from the printed page.

Line amounts round to cents before summing. The discount reduces taxable and exempt items proportionally, and shipping is added after tax. The tool remembers the last invoice number you sent to the print dialog and suggests the next one (INV-0009 → INV-0010); check the number if you canceled printing. Once payment arrives, Create receipt from invoice transfers your items, contact details, logo, and totals to the Receipt Generator in this tab.

A good invoice includes: who it's from and to, a unique invoice number, issue and due dates, itemized charges, tax, the total due, and how to pay. Unlike a receipt (which records a completed payment), an invoice is a request for payment.
