How invoice generator works
An invoice is a document that records what a client owes you for goods or services. This generator builds one from a list of line items, each with a description, quantity and unit price, then applies an optional discount and sales tax to produce a clean, printable total.
Enter your business name, who you are billing, an invoice number and date, and one line item per line using the format description, quantity, unit price (for example: Web design, 10, 75). Add an optional flat discount, a sales-tax percentage, and a payment-terms line (Due on receipt, Net 15/30/45/60) that prints on the invoice. The tool multiplies each line quantity by its unit price, sums the subtotal, subtracts the discount, applies the tax to the discounted amount, and returns the total due.
The result renders as a formatted invoice document you can print directly from your browser (use the Print Invoice button, then choose Save as PDF as the destination). Everything runs locally in your browser - no data is uploaded, so client details stay private.
