Before you start

A few useful answers.

Are the tools free, without a watermark?

All four generators are free to use, require no account and add no NineBrief watermark to your finished document.

Where is my work saved?

Each tool keeps a working draft in this browser when local storage is available. It is not an online document history or a cloud backup. Export an editable JSON backup before clearing browser data, changing devices or starting another document.

How do I save a PDF?

Check your document, then choose Download PDF. In the browser print dialog, choose Save as PDF. The printed document leaves out the editor controls.

Which document should I use?

Use an invoice to request payment, a quote or estimate to propose work and prices, a purchase order to order from a supplier, and a delivery note to record what was delivered.
