Cosign is best for
When you need accountability, status, and completion proof.
Comparison
Cosign vs email attachments
Use Cosign when you want private request links, status tracking, and completion proof for one document without unnecessary workspace overhead.
Alternative
Email attachments
Tradeoff
Email is familiar, but it does not show a reliable request status or signer-specific audit trail.
Cosign focus
Upload a document, add signers, send private links, and know where the request stands.
Not trying to be
A broad document library, team chat, file editor, or proposal platform.
Good fit
Small businesses, agencies, consultants, accountants, brokers, and operators.
