Projects & collaboration

Sign

Electronic signatures on PDFs

Upload a PDF, add the people who sign it and send it. RIO does not send email: you share each outside signer’s link yourself.

Open Sign

Opens in RIO. You will be asked to sign in if you are not already, and you see it when your role allows.

Who uses it

Sales, HR and anyone collecting signatures.

What teams do with it

  • Sign an offer letter

    Upload the letter, add the candidate as signer and share their link.

  • Countersign a vendor agreement

    Choose sequential signing so your director signs after the vendor.

  • Sign what is sent to you

    Requests addressed to you show in Sign when you log in.

Key features

  • PDF upload with type and size checks
  • Multiple signers, in order or in parallel
  • Private signing links for outside signers
  • Signed document download

Connected apps
