What every invoice needs

A valid invoice has: your business name and contact, the client's details, a unique invoice number, the date, an itemised list of what you're charging for (description, quantity, price), any tax, and the total due. Add payment terms (e.g. 'due within 14 days') and how to pay. Keep your invoice numbers sequential — it makes bookkeeping and tax time far easier.

Frequently asked questions

Is this invoice generator really free?

Yes — fill in the fields, download the PDF, no signup or watermark. Everything runs in your browser, so your client and pricing details never leave your device.

Is a PDF invoice legally valid?

Yes, a PDF invoice with your details, the client's, a number, date, itemised charges and total is perfectly valid in most countries. Check local tax rules for what else (like a VAT/tax number) you must include.

Can I add tax or VAT?

Yes — enter a tax percentage and the tool adds it to the subtotal and shows the total. For multiple tax rates or recurring billing, a dedicated invoicing tool is easier.

What if I send lots of invoices?

A generator is great for occasional invoices. If you're invoicing regularly and need to track who's paid and chase late payers, a payments platform like Melio handles sending, tracking and getting paid.
