Sending a proposal without a DRAFT watermark risks the client forwarding it as final. A contract without CONFIDENTIAL stamp gets printed and left on a desk. Watermark PDF prevents both — in 10 seconds.

Why Watermark Before Sharing

  • Draft control: Recipient knows not to forward or print as final.
  • Confidentiality: “CONFIDENTIAL — Do Not Distribute” deters casual sharing.
  • Branding: Subtle logo watermark brands proposals without a cover letter.
  • Copy deterrent: Tiled watermark makes clean photocopy harder.
