What's the cheapest e-signature software?

Dataroom at $9.99/month per Org + $5/seat (3 included) with unlimited envelopes is typically the cheapest for any team over ~2 people - even past the 3 included seats, $5/seat beats the $25–65/seat charged everywhere else. Free tiers from competitors are usually limited to 3 envelopes/month.

Are all five legally binding?

Yes - electronic signatures are legally recognized under eIDAS (EU), ESIGN and UETA (US) when properly implemented, and all five ship audit-grade certificates of completion. For life sciences, validate 21 CFR Part 11 support specifically.

Which is easiest to migrate to?

Dataroom imports DocuSign templates and active envelopes automatically; most teams migrate in 2 hours. Dropbox Sign and Adobe Sign also have migration tools. PandaDoc requires manual rebuild.
