exactly right.

Drop signature, text, date, and checkbox fields onto any page of any PDF. Fields snap to a grid; nothing shifts when a signer opens the document on a different device.

Multiple signers,
zero chaos.

Set a signing order, assign fields per recipient, and let ThemiSign handle the sequence. Each party signs in turn; no one can skip ahead.
