Frequently Asked Questions

How much does DocuSign cost per year?

DocuSign Standard costs $25/user/month ($15,000/year for 50 users). Business Pro costs $40/user/month ($24,000/year). Both have envelope limits — exceeding them requires purchasing additional envelopes. API access needed for integration requires Business Pro at minimum.

Can I replace DocuSign with custom e-signature software?

Yes. A custom e-signature platform using open-source signing technology costs $40,000 to build with $3,000/year maintenance. Over 5 years: $52,000 vs. $75,000–$120,000 DocuSign. Custom platforms have unlimited signatures, full API access, and your branding.

What are DocuSign envelope limits?

DocuSign plans include a fixed number of envelopes per year. Exceeding this limit requires purchasing additional envelope packs or upgrading your plan. For high-volume organizations (1,000+ documents/month), these overage costs can be significant and unpredictable.
