Award-winning eSignature solution
What a valid digital signature means
A valid digital signature is an electronic signature process that ties a signer’s identity to a document and records proof of intent, integrity, and timing. In the U.S., it works by combining signer authentication, a signed record, and a tamper-evident audit trail so the document can be traced back to the person who signed it. signNow supports this workflow with secure signing, document history, and verification tools that help preserve evidentiary value under ESIGN and UETA.
Why valid digital signatures matter
A valid digital signature reduces paper handling, speeds approvals, and supports enforceability by preserving evidence of intent and record integrity. Under ESIGN and UETA, it can satisfy legal requirements for many U.S. transactions when consent, attribution, and retention are handled correctly.
Common signature challenges
Signer identity can be disputed when authentication is weak or shared across multiple users. Missing audit details can make it harder to prove who signed, when, and from where. Poor retention practices can leave signed records unavailable during audits or litigation. Inconsistent workflows can create version mismatches between the signed file and the final record.
Who uses valid digital signatures

How the signing flow works
A valid digital signature follows a simple sequence that connects identity, consent, and a preserved record.
Open document: The signer opens the document and reviews the request. Verify identity: Identity is verified before the signature step begins. Sign and seal: The signature is applied and the record is sealed. Store record: The completed file is stored with its audit trail.

Real-world use cases
Customer stories show how valid digital signatures fit operational, compliance, and customer-service workflows across industries.
Enterprise operations
A NetSuite operations leader needed signatures tied to business systems, not separate email threads.
- Kodi-Marie Evans at Xerox used signNow with NetSuite.
The workflow kept the right signatures on the right documents and reduced manual routing across systems.
Healthcare practice
A healthcare founder needed secure signing for patient-facing records and internal approvals.
- John Butler at Fertility Centers of Illinois valued the API and responsiveness.
The result was a more controlled signing process with stronger record handling for regulated documents and mobile use.
Best practices for signing
A consistent policy helps teams keep signatures defensible, searchable, and easier to audit over time.

FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and signing issues that affect valid digital signature workflows in the U.S.
signNow Business starts at $8/user/mo billed annually, while Business Premium adds bulk send. If you need HIPAA handling, confirm a BAA and the correct plan before rollout.
If a signer cannot complete the flow on mobile, use the signNow iOS or Android app, or a supported browser such as Chrome, Safari, or Edge. Mobile-created eSignatures remain valid under ESIGN and UETA when intent is clear.
If you need stronger evidence for a regulated file, review the audit trail, timestamps, and document history. For FDA-regulated records, 21 CFR Part 11 requires secure audit trails and unique user identification.
If a document must be retained for healthcare use, keep the signed record for 6 years under HIPAA 45 CFR 164.530(j)(2), unless another rule requires longer retention.
If a signer disputes authorship, use the audit trail, signer authentication details, and document history to show attribution under ESIGN and UETA. Stronger authentication improves evidentiary weight.
If your team needs more controlled routing, signNow Business Premium adds bulk send, and Enterprise adds advanced signer authentication and integrations for larger workflows.
