Build a proper invoice. Keep it local.

The math. Subtotal is the sum of quantity × rate. A percentage discount comes off the subtotal, then tax applies to the discounted amount - the ordering most jurisdictions use. If your tax authority taxes the pre-discount amount, or you need line-level tax rates, this simple model is not enough; check your local rules.

Print to PDF. The download button opens your browser’s own print dialog with the page styled so only the invoice prints, sized for A4 and US Letter. Nothing is uploaded, rendered server-side, or watermarked - the PDF your browser writes is yours.

What saves where. Your business details, currency, tax rate, and notes persist in this browser’s localStorage so repeat invoices start pre-filled. Client names and line items are deliberately never stored. Clear it any time with the button in the form; nothing ever reaches a server.

What this tool does not do. Sequential numbering, delivery, payment links, reminders when an invoice goes unpaid, and reconciling what actually arrived at the bank. A generator makes documents; getting paid is a workflow.

Not accounting advice. This produces a clean, standard invoice document. Whether its contents satisfy your tax regime (VAT lines, reverse-charge notices, e-invoicing mandates) is between you and your accountant.
