What is E-Signature Software?

E-signature software allows users to electronically sign documents, creating a legally binding agreement without paper. It manages the entire workflow, from sending the document to collecting signatures, creating an audit trail, and storing the executed copy securely.

How does it ensure legal validity?

Top providers comply with regulations like the U.S. ESIGN Act, UETA, and Europe's eIDAS. They create a comprehensive audit trail that records every action taken on the document, including IP addresses, timestamps, and signer identity verification, which can be used as evidence in court.

How to choose

What is the difference between an electronic signature and a digital signature?

An electronic signature is a broad term for any electronic process that indicates acceptance of an agreement (e.g., a typed name, a scanned image of a signature). A digital signature is a specific, more secure type of electronic signature that uses certificate-based digital IDs to encrypt and authenticate the document's integrity.
