Why Teams Switch from DocuSign to SigPen
No Per-Envelope Fees
DocuSign charges you every time you hit send. One busy month and your bill doubles. SigPen is one flat rate, send as many documents as you want.
AI That Actually Helps
SigPen's AI reads your PDF and places signature, date, and text fields automatically. DocuSign still requires manual field placement on every document.
Same Legal Standing
Both platforms are ESIGN Act and UETA compliant. SigPen signatures carry the exact same legal weight as DocuSign, at a fraction of the cost.
Frequently Asked Questions
Is SigPen legally equivalent to DocuSign?
Yes. Both SigPen and DocuSign produce ESIGN Act and UETA-compliant electronic signatures. Every SigPen signature includes a full audit trail with timestamps, IP addresses, and signer consent records, the same evidentiary standard used by DocuSign.
Can I import my existing DocuSign templates into SigPen?
You can upload any PDF to SigPen and use our AI field detection to automatically place signature, date, and text fields. If you have specific templates, just re-upload the underlying PDF and you're set.
What happens to my documents if I cancel?
Your signed documents and audit trails are always downloadable as PDFs. We never hold your data hostage. Cancel anytime and download everything before you go.
Does SigPen support multiple signers?
Yes. You can add as many signers as needed per document, assign specific fields to each signer, and set signing order if required. Recipients sign via a secure link, no SigPen account needed.
How does SigPen handle API integrations?
SigPen's Business plan includes full REST API access with webhooks, mergeData for pre-filling fields, and an embeddable signing widget. This is typically an enterprise-only feature at DocuSign.
