The Invoice Generator is a free, browser-based tool for creating professional invoices you can download as a print-ready PDF. You fill in your business details, client information, and a table of line items (description, quantity, unit price), and the tool automatically calculates line subtotals, applies tax, and produces the grand total. It supports Indian GST breakdowns (CGST, SGST, and IGST) as well as a flat percentage tax rate for other regions, plus optional discounts and shipping.

It is built for freelancers, consultants, small businesses, and shop owners who need a clean invoice without buying accounting software or logging into an online account. Everything runs locally in your browser, so you can generate a GST-compliant invoice in a minute and send the PDF to your client by email.

Each line item's amount is quantity multiplied by unit price. The tool sums every line amount to get the taxable subtotal, subtracts any discount, then applies tax on the result. For example, three units at 500 each gives a 1,500 line total; a 200 discount brings the taxable value to 1,300.

For Indian GST, an 18 percent rate on a 1,300 taxable value is split equally for intra-state sales: CGST at 9 percent (117) and SGST at 9 percent (117), totalling 234 in tax. For inter-state sales the same 18 percent is charged as a single IGST line (234). Shipping is added after tax, and the grand total is taxable value plus tax plus shipping. The tool shows each component separately so the invoice stays transparent and audit-friendly.

The PDF is generated entirely in your browser from the values you type. No template server is involved, so the layout, currency symbol, and totals reflect exactly what you entered.
