When you're sent an agreement to sign via Shortlist, you can easily sign it electronically in your portal.
First, you will receive an email notification that an agreement has been sent for your signature.
Once you follow the link in that email, you will be taken to the Documents section of your portal. Your unsigned agreements will be designated as New. Click on the document title to review and sign.
Once you have signed the agreement, your client will receive notification that it is complete.
