Sign is an e-signature tool built for individuals and small teams, not enterprise procurement. Upload a document, place signature/date/text fields, send it, and get it back signed, hashed, and backed by a full audit trail -- all without the per-seat pricing that DocuSign and Adobe Sign charge a company for.
Free to start (3 envelopes/mo), $8/mo for 25 envelopes, or $19/mo unlimited -- no seat fees at any tier.
