Introduction to WPsigner

WPsigner is a professional electronic signature plugin that transforms your WordPress site into a complete document signing platform. Unlike SaaS alternatives that charge per envelope, WPsigner is a one-time purchase with unlimited signatures.

Why WPsigner?

Self-Hosted & Private

Your documents never leave your server. Unlike DocuSign, HelloSign, or Adobe Sign, your sensitive contracts, agreements, and personal data stay under your complete control.

No Per-Envelope Fees

Most e-signature services charge $1-3 per document. With WPsigner, you pay once and sign unlimited documents forever. Send 10 or 10,000 documents—the cost remains the same.

Legally Binding

WPsigner signatures are legally valid and enforceable under:

Regulation	Region	Status
ESIGN Act	United States	✅ Compliant
UETA	All 50 US States	✅ Compliant
eIDAS	European Union	✅ Simple Electronic Signature (SES)
PIPEDA	Canada	✅ Compliant
ECA	Australia	✅ Compliant

White-Label Ready

Remove all WPsigner branding and replace with your own company logo, colors, and email templates. Perfect for agencies and enterprises.
