FAQ
Is this invoice generator free?
Yes. The invoice generator is free to use, works without an account and runs entirely in your browser.
Can I download the invoice as a PDF?
The tool downloads a clean HTML invoice. Open that file in your browser and use the browser print dialog to save it as PDF if you need a PDF copy.
Does the invoice generator store my client details?
No. The invoice data stays in your browser session and is not uploaded to a server.
How is tax calculated?
Tax applies only to lines marked taxable. If you add a discount, the taxable subtotal is reduced proportionally before the tax rate is applied.
Can I use a fixed discount instead of a percentage?
Yes. Choose fixed discount, enter the amount, and the calculator caps the discount at the subtotal so the invoice cannot go below zero before tax.
Can I track a partial payment?
Yes. Enter the amount already paid and the invoice generator will show the remaining amount due or any overpayment credit.
Is this a replacement for accounting software?
No. It is a fast invoice maker and calculator. Check local tax rules, legal requirements and your accounting records before sending official invoices.
