Add your client and place the fields
Type their name and email, or a mobile number for a text. Click where they sign, initial and date. Siggy can find the signature lines for you.
Your client signs on their phone
They open the link, read the document, and draw, type or upload a signature. No account and no app.
Need to be sure who they are? Add an identity check: photo ID and a selfie, from $6.00.
Everyone gets the signed copy
When the last person signs, Siggy seals the document, adds the certificate of completion and emails it to everyone. You will see it in Agreements straight away.
The signed document and certificate are attached.
Made for the practices that send these every week
