Top 8 E-Signature Tools

Ranked by SMB value:

Free Tier Comparison

iContract: unlimited signatures free. DocuSign: 3 envelopes/month free. Dropbox Sign: 3/month. signNow: trial only. Most others: trials or document caps. iContract's free tier is the only genuinely 'unlimited' option.

When DocuSign Still Wins

DocuSign has the most signer trust — recipients recognize the brand and click links faster. For B2B sales to large enterprises, DocuSign's enterprise integrations (SAP, Salesforce, Oracle) are deeper. But you pay 5-7x more for these advantages.

When iContract Wins

Better economics: free for unlimited signatures vs $10-$65/month elsewhere. Plus AI contract generation (no other e-sign tool has this). Plus 14+ free legal tools. The full stack at SMB pricing.
