Signers never need a SahlSign account. The signing flow is:
- They receive an invitation email with a "Sign Document" button
- The button opens a unique signing page (the URL contains a one-time token)
- They review the document, accept the electronic-signature disclosure, and start filling fields
- Before submitting, they verify identity via a one-time code sent to their email
- They click Submit. The signed PDF + Certificate of Completion arrive in their inbox
Only the sender — the person initiating the signature request — needs a SahlSign account. This keeps friction near zero for signers, which dramatically improves completion rates.
What if a signer wants to keep a copy?
The completion email includes both the signed PDF and the Certificate of Completion as attachments. Signers also get a verify URL they can revisit any time at /verify/{document-id} to confirm the document hasn't been tampered with.
