Is this really free, with no catch?

Yes. It runs entirely in your browser, so hosting it costs us nothing per invoice. The site earns from ads elsewhere, not from gating basic paperwork.

How do I get a PDF instead of a printout?

Hit the print button and choose Save as PDF as the destination. Every modern browser has it, and the output is a clean A4/Letter document without site chrome.

What must an invoice legally include?

In the US at minimum: who you are, who the client is, a unique number, a date, what was delivered, and the amount due. VAT jurisdictions add tax IDs and rates. When in doubt, ask your accountant, not a template.

The math

Line net = quantity × unit price − line discount. Subtotal = sum of nets. The invoice discount applies to the subtotal; every tax applies to the discounted base (per line when a tax varies by line, like mixed VAT rates). Total = base + added taxes − withheld taxes.

What this ignores

Jurisdiction-specific legal requirements (VAT IDs, e-invoicing mandates, sequential-numbering rules) and currency conversion. It produces a clean, correct document; your local rules decide what else must be on it.
