Electronic Signature Vs Wet Signature Guide
Award-winning eSignature solution
What electronic signature means
Electronic signature vs wet signature compares a digital signing method with ink on paper. An electronic signature is any electronic sound, symbol, or process attached to a record with intent to sign. In U.S. business use, it can capture consent, approvals, and acknowledgments through a browser, mobile app, or link. A wet signature is handwritten ink on a physical document. Both can be valid, but electronic workflows add identity records, timestamps, and easier storage.
Legal value and business effect
Electronic signature vs wet signature matters because ESIGN and UETA give electronic signatures legal effect for most U.S. business transactions, while reducing paper handling, courier delays, and manual filing. With SignNow, teams can keep a documented audit trail and support enforceability without changing the underlying business record.
How electronic signing works
The process is straightforward: prepare the file, deliver it to signers, capture consent and signatures, then preserve the signed record with supporting evidence.
Prepare: Prepare the document, define fields, and choose the signing order. Deliver: Send by link or email, then notify each signer. Sign: Signer reviews, authenticates, and signs on device. Complete: System seals the file, stores the audit trail, and archives it.

FAQ and troubleshooting
These answers cover signing, compliance, and plan-level questions that affect how a U.S. team uses electronic signatures versus wet signatures.
SignNow supports legally binding eSignatures under ESIGN and UETA on paid plans, with audit trails and templates for traceability. If your document needs HIPAA coverage, a BAA is required when PHI is involved, and the workflow should use appropriate access controls.
For HIPAA-related forms, SignNow can be used if your organization has a signed BAA and follows HIPAA Security Rule safeguards. The signed record should include access controls, audit controls, and retention practices aligned to 45 CFR 164.530(j)(2).
If a deal needs higher signer assurance, use identity verification methods such as SMS OTP or ID verification. SignNow’s workflow can record signer history and timestamps, which helps attribute the signature to the right person.
The Business plan includes core eSignature features, while Business Premium adds bulk send and kiosk mode, and Enterprise adds advanced signer authentication. If a feature is missing, confirm the plan tier before changing the workflow.
When a signed PDF looks altered, check the audit trail and document history first. SignNow preserves tamper-evident records, so any post-signing change should be visible through the file history and evidence package.
Some documents still require wet ink because ESIGN and UETA exclude certain document types, and state law may add more rules. Wills, some court orders, and documents needing notarization or witnesses may still need a paper process.
