How to make an invoice
A good invoice answers four questions at a glance: who is billing, who is being billed, what for, and how much. Fill in your details on the left and the preview updates instantly. When it looks right, download it as a PDF and send it on.
What every invoice should include
At minimum: your business name and contact details, the client's details, a unique invoice number, the date and a due date, a clear list of items with amounts, and the total. Adding payment terms in the notes — like "due within 14 days" — helps you get paid on time.
Pick a look that fits
The ten templates above change the colour and header style so your invoice matches your brand, from bold and colourful to clean and minimal. The numbers and layout stay clear and professional in every one.
