Digital Signature Purpose for SignNow
Award-winning eSignature solution
What a digital signature ensures
A digital signature is a cryptographic way to sign a record so the signer can be identified and the document can be checked for tampering. It uses public key infrastructure, a private key to create the signature, and a public key to verify it. In practice, the signature binds the signer’s identity to the document, records the signing event, and helps show that the file has not changed after signing. Under U.S. law, it supports reliable electronic execution.
Why digital signatures matter legally
They reduce paper handling, speed approvals, and create stronger evidence of intent and integrity. Under ESIGN and UETA, a properly attributed digital signature can be enforceable like a handwritten one when consent, identity, and record retention are handled correctly.
Common digital signature pitfalls
Signer identity can be disputed when authentication is too weak or the record lacks clear attribution. Documents may lose evidentiary value if timestamps, IP data, or audit details are incomplete. Compliance gaps appear when retention, consent, or access controls do not match HIPAA, FERPA, or ESIGN needs. Tampering risk rises when the workflow does not preserve a hash, audit trail, and sealed final copy.
Who uses digital signatures
Organizations
Organizations use digital signatures to ensure contracts, approvals, and disclosures stay attributable, intact, and legally usable across remote workflows.
Teams
Teams use them for leases, patient forms, tax documents, loan files, and internal approvals that need clear signer intent.
People who benefit most
A director of NetSuite operations at Xerox can route approvals through connected systems, keep the right signature on the right document, and preserve a defensible record for internal controls and external review. A COO at a growth-stage firm can replace paper routing with mobile signing, reduce turnaround time, and keep customer-facing documents simple enough for nontechnical signers to complete quickly.

Core features that support signing
signNow pairs signing controls with recordkeeping features so the signature stays attributable, verifiable, and easier to manage across teams.
Signer binding
Creates a cryptographic link between the signer and the document, helping show who signed and whether the file changed afterward.
Audit trail
Captures signing events in a tamper-evident record, which supports disputes, audits, and internal review.
Identity checks
Uses identity checks such as SMS OTP, ID verification, or other methods to strengthen attribution.
Mobile access
Supports mobile signing on iOS, Android, macOS, and Windows without changing the legal effect of the signature.
Reusable workflows
Works with templates and reusable workflows so recurring documents move faster without losing record integrity.
Compliance support
Helps teams keep electronic records organized for ESIGN, UETA, HIPAA, and other U.S. requirements.
How the signing flow works
A digital signature follows a short sequence that links identity, consent, and document integrity from start to finish.
Open document: The signer opens the document and reviews the request. Verify identity: Identity is verified before signing begins. Apply signature: The signature is applied and sealed to the record. Store record: The completed file is stored with its audit history.
Quick steps to send a document
Use a simple sequence to prepare, send, and store a signed document without adding extra manual work.
Prepare file:
Upload the file and set the signing order. Set verification:
Choose the signer authentication method. Place fields:
Add fields, initials, and signature boxes. Send request:
Send the document for signature. Save record:
Download the completed copy after signing.
Recommended workflow settings
Set the signing workflow to preserve identity, integrity, and retention evidence across regulated and general business documents.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for routine remote signing |
| Signature type | Cryptographic digital signature |
| Audit trail | UTC timestamps and IP logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 in transit, AES-256 at rest |
Browser and device support
signNow works in modern browsers and on mobile devices, with encrypted connections used during signing and review.
Desktop browsers Chrome, Firefox, Edge, and Safari supported Mobile devices iOS and Android mobile apps available Operating systems Windows and macOS supported for web signing
For regulated deployments, managed devices, SSO, API access, and retention controls may matter more than the device itself. Teams should confirm browser policy, mobile access, and admin settings before rollout, especially when HIPAA, FERPA, or internal security rules apply.

Real-world signing examples
These examples show how digital signatures support remote execution, record integrity, and faster document handling in real business settings.
Enterprise operations
A NetSuite operations leader needed the right signatures on the right documents, in the right formats, across connected workflows.
- Xerox used signNow with NetSuite integration.
The team kept routing aligned with system records and reduced manual signature handling across document types.
Real estate
A real estate founder needed online execution with built-in security, mobile access, and a clear compliance record for clients.
- Martin Properties processed documents online.
- Mobile and offline signing were used.
The workflow supported remote execution while keeping the signing record organized for review and follow-up.
Best practices for reliable signing
A reliable signing process depends on identity controls, retention rules, and a record that can stand up to review later.
Match authentication to risk
Preserve full audit evidence
Define retention early
Restrict signing access
FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and signing issues that affect legal use and document handling.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. If a signer cannot complete the flow, check consent, browser support, and whether the document needs stronger authentication for the transaction type.
For HIPAA workflows, signNow supports HIPAA compliance with a BAA. If PHI is involved, confirm the agreement is signed, access is restricted, and records are encrypted at rest and in transit.
If you need bulk send, use Business Premium or higher. The Business plan is priced at $8/user/mo annually and includes core eSignatures, but bulk send is listed on Business Premium.
If your document must support 21 CFR Part 11, use controls such as unique user identification, timestamps, and retained history. signNow’s compliance features should be matched to the regulated process and validated internally.
If a signature is questioned in court, the audit trail matters. signNow records signing events, and a complete log helps support attribution, intent, and document integrity under ESIGN and UETA.
If a user cannot access a document on mobile, confirm the device supports iOS or Android signing and that the browser is current. signNow also supports desktop use in Chrome, Firefox, Safari, and Edge.
