Invoice Generator

A single-page invoice generator: fill in the business and the client, add line items, set a tax rate and a currency, preview, download the PDF. A PayPal.me link becomes a QR code on the invoice. Nothing leaves the browser: there is no backend and no account.

Status: maintained as a utility, not a product. Dependencies are kept current (Dependabot is on); features are added when someone needs them.

Features

• Business and client details, with an optional logo upload.
• Line items with quantity and unit price; subtotal, tax and total computed as you type.
• Tax rate per invoice, including 0% for exempt or reverse-charge invoices.
• Currency selection with locale-aware formatting.
• Automatic invoice numbering, invoice and due dates, free-text notes.
• Preview, PDF download (jsPDF), and a QR code for the PayPal.me payment link.
• Light and dark mode; responsive layout.

The "Send by email" button only simulates a send: there is no mail service behind the app. Download the PDF and attach it.
