About Invoice Generator

Fill in your details, your client's details, and a list of line items, then download a clean single-page A4 invoice as a PDF. Supports seven currencies (USD, EUR, GBP, PKR, INR, CAD, AUD), a percentage tax rate, a flat discount, and free-form payment terms. Totals update live as you type, and the PDF is generated on your device with no account or watermark.

Freelancers and small businesses often need one invoice right now, not a subscription to an invoicing platform. This generator produces a clean, single-page A4 invoice as a PDF: enter who the invoice is from, who it bills, an invoice number with issue and due dates, and the line items, then download the file and send it. There is no account, no watermark, and no template gallery to wade through.

Each line item takes a description, a quantity, and a unit price. Amounts are computed per row and summed into a live summary. A flat discount is subtracted from the subtotal first, then the tax rate is applied to the discounted amount, which matches how most jurisdictions expect sales tax or VAT to be calculated. Seven currencies are supported (USD, EUR, GBP, PKR, INR, CAD, AUD) and the chosen symbol appears in both the on-screen totals and the PDF. The layout uses Helvetica with a ruled items table, right-aligned amounts, and wrapped descriptions, so long item text stays readable instead of overflowing the column.

The PDF is built on your device with the pdf-lib library; nothing you type is sent to a server. The tool remembers only your currency and tax rate between visits. Client names, addresses, line items, and notes are never stored, so a shared computer does not leak billing details.

Frequently asked questions
Is my client's billing information private?

Yes. The PDF is generated by JavaScript running in your browser, so names, addresses, and amounts never leave your device. The tool stores only your currency and tax rate preferences locally; it never saves invoice content.

How is tax calculated when there is also a discount?

The flat discount is subtracted from the subtotal first, then the tax rate is applied to the discounted amount. This matches the usual treatment of sales tax and VAT on discounted invoices.

Can I add a logo or change the template?

Not yet. The output is a fixed single-page A4 layout in Helvetica with a ruled items table. It is designed to look standard and print cleanly rather than be customizable.

How many line items fit on the invoice?

Up to 20. The layout is single-page A4, and 20 rows with wrapped descriptions is the practical limit before content runs off the page. Long descriptions wrap automatically.

Is the generated invoice legally valid?

An invoice is valid when it contains the details your jurisdiction requires: typically both parties' names and addresses, a unique number, dates, itemized amounts, and tax. The PDF includes fields for all of these, but check local rules for extras such as tax IDs.
