After a proposal is signed, both you and the client receive a PDF copy by email. You can also download it manually at any time.
Manual download
Go to the Proposals list → find the signed proposal → click the three-dot menu → Download PDF. The PDF includes the proposal content and the audit trail summary on the final page.
Note
PDF generation is on demand, the file is created fresh at download time, always reflecting the content at the moment of signing (not any subsequent edits).
