Prime eSign
Electronic signatures you can stand behind
Send agreements for signature with a complete audit trail. Standard for everyday documents; High Assurance when stronger proof is required.
Why eSign
Upload a document, place signature fields and send a secure link. Signers complete without creating an account — and you retain a full record.
When the agreement must remain provable, High Assurance adds email verification before signing, sealed documents and independent verification.
