Invoice Generator turns a short form into a printable A4 invoice and downloads it as a PDF. Line-item amounts are calculated in integer cents, so a quantity of three at 19.99 does not drift by a cent the way repeated floating-point multiplication can. One tax rate is applied to the subtotal, and the PDF shows subtotal, tax and total separately rather than hiding the arithmetic. Long descriptions wrap, the table repeats its header on a new page, and the totals block stays with the last rows instead of splitting across pages. The form validates the fields that make an invoice unusable — a missing sender, a missing client, an item with no price — before any document is produced. Everything is generated on your device with pdf-lib; the client name, amounts and output file are never uploaded, logged or stored.

Frequently asked questions about Invoice Generator
Does this invoice generator store my client details?
No. The form and the PDF generation run in the browser; nothing is saved on a server or in the page after you leave.
How is tax calculated?
Tax is a single percentage applied to the subtotal, which is the sum of quantity times unit price for each line, rounded in cents.
Can I use a different currency?
Yes. Pick a currency code and amounts are formatted with it. The tool does not convert values between currencies.
Is this a legally compliant invoice?
It is a document generator, not legal or tax advice. Requirements vary by country and business type, so check the fields your jurisdiction requires.
