Quick answer

What is E-signature Software?

E-signature software lets people sign contracts and forms online with a legally recognised electronic signature, an audit trail and tamper evidence. Plans differ by senders, envelope limits, templates, integrations and API access.

E-signatures replace printing, scanning and couriering documents, cutting turnaround from days to minutes.

This category covers market leaders (DocuSign, Adobe Acrobat Sign, Dropbox Sign), document automation (PandaDoc), affordable and developer-friendly tools (SignNow, BoldSign, SignWell, Signeasy, Zoho Sign) and enterprise platforms for regulated industries (OneSpan Sign).

Prices range from free plans to about $45 per user a month, and envelope caps matter as much as seat prices. The profiles below summarise dated sources and are research aids, not legal advice or rankings.
